 * \brief Set resource limits

 * clamping to minimum or maximum values, rounding up to nearest element
 * size, etc). The application can use ::cuCtxGetLimit() to find out exactly
 * what the limit has been set to.
 *
 * Setting each ::CUlimit has its own specific restrictions, so each is
 * discussed here.
 *
 * - ::CU_LIMIT_STACK_SIZE controls the stack size in bytes of each GPU thread.
 *   The driver automatically increases the per-thread stack size
 *   for each kernel launch as needed. This size isn't reset back to the
 *   original value after each launch. Setting this value will take effect 
 *   immediately, and if necessary, the device will block until all preceding 
 *   requested tasks are complete.
 *
 * - ::CU_LIMIT_PRINTF_FIFO_SIZE controls the size in bytes of the FIFO used
 *   by the ::printf() device system call. Setting ::CU_LIMIT_PRINTF_FIFO_SIZE
 *   must be performed before launching any kernel that uses the ::printf()
 *   device system call, otherwise ::CUDA_ERROR_INVALID_VALUE will be returned.
 *
 * - ::CU_LIMIT_MALLOC_HEAP_SIZE controls the size in bytes of the heap used
 *   by the ::malloc() and ::free() device system calls. Setting
 *   ::CU_LIMIT_MALLOC_HEAP_SIZE must be performed before launching any kernel
 *   that uses the ::malloc() or ::free() device system calls, otherwise
 *   ::CUDA_ERROR_INVALID_VALUE will be returned.
 *
 * - ::CU_LIMIT_DEV_RUNTIME_SYNC_DEPTH controls the maximum nesting depth of
 *   a grid at which a thread can safely call ::cudaDeviceSynchronize(). Setting
 *   this limit must be performed before any launch of a kernel that uses the
 *   device runtime and calls ::cudaDeviceSynchronize() above the default sync
 *   depth, two levels of grids. Calls to ::cudaDeviceSynchronize() will fail
 *   with error code ::cudaErrorSyncDepthExceeded if the limitation is
 *   violated. This limit can be set smaller than the default or up the maximum
 *   launch depth of 24. When setting this limit, keep in mind that additional
 *   levels of sync depth require the driver to reserve large amounts of device
 *   memory which can no longer be used for user allocations. If these
 *   reservations of device memory fail, ::cuCtxSetLimit() will return
 *   ::CUDA_ERROR_OUT_OF_MEMORY, and the limit can be reset to a lower value.
 *   This limit is only applicable to devices of compute capability 3.5 and
 *   higher. Attempting to set this limit on devices of compute capability less
 *   than 3.5 will result in the error ::CUDA_ERROR_UNSUPPORTED_LIMIT being
 *   returned.
 *
 * - ::CU_LIMIT_DEV_RUNTIME_PENDING_LAUNCH_COUNT controls the maximum number of
 *   outstanding device runtime launches that can be made from the current
 *   context. A grid is outstanding from the point of launch up until the grid
 *   is known to have been completed. Device runtime launches which violate
 *   this limitation fail and return ::cudaErrorLaunchPendingCountExceeded when
 *   ::cudaGetLastError() is called after launch. If more pending launches than
 *   the default (2048 launches) are needed for a module using the device
 *   runtime, this limit can be increased. Keep in mind that being able to
 *   sustain additional pending launches will require the driver to reserve
 *   larger amounts of device memory upfront which can no longer be used for
 *   allocations. If these reservations fail, ::cuCtxSetLimit() will return
 *   ::CUDA_ERROR_OUT_OF_MEMORY, and the limit can be reset to a lower value.
 *   This limit is only applicable to devices of compute capability 3.5 and
 *   higher. Attempting to set this limit on devices of compute capability less
 *   than 3.5 will result in the error ::CUDA_ERROR_UNSUPPORTED_LIMIT being
 *   returned.
 *
 * - ::CU_LIMIT_MAX_L2_FETCH_GRANULARITY controls the L2 cache fetch granularity.
 *   Values can range from 0B to 128B. This is purely a performence hint and
 *   it can be ignored or clamped depending on the platform.
 *
 * - ::CU_LIMIT_PERSISTING_L2_CACHE_SIZE controls size in bytes availabe for
 *   persisting L2 cache. This is purely a performance hint and it can be
 *   ignored or clamped depending on the platform.

 *
 * Allocates \p bytesize bytes of managed memory on the device and returns in
 * \p *dptr a pointer to the allocated memory. If the device doesn't support
 * allocating managed memory, ::CUDA_ERROR_NOT_SUPPORTED is returned. Support
 * for managed memory can be queried using the device attribute
 * ::CU_DEVICE_ATTRIBUTE_MANAGED_MEMORY. The allocated memory is suitably
 * aligned for any kind of variable. The memory is not cleared. If \p bytesize
 * is 0, ::cuMemAllocManaged returns ::CUDA_ERROR_INVALID_VALUE. The pointer
 * is valid on the CPU and on all GPUs in the system that support managed memory.
 * All accesses to this pointer must obey the Unified Memory programming model.
 *
 * \p flags specifies the default stream association for this allocation.
 * \p flags must be one of ::CU_MEM_ATTACH_GLOBAL or ::CU_MEM_ATTACH_HOST. If
 * ::CU_MEM_ATTACH_GLOBAL is specified, then this memory is accessible from
 * any stream on any device. If ::CU_MEM_ATTACH_HOST is specified, then the
 * allocation should not be accessed from devices that have a zero value for the
 * device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS; an explicit call to
 * ::cuStreamAttachMemAsync will be required to enable access on such devices.
 *
 * If the association is later changed via ::cuStreamAttachMemAsync to
 * a single stream, the default association as specifed during ::cuMemAllocManaged
 * is restored when that stream is destroyed. For __managed__ variables, the
 * default association is always ::CU_MEM_ATTACH_GLOBAL. Note that destroying a
 * stream is an asynchronous operation, and as a result, the change to default
 * association won't happen until all work in the stream has completed.
 *
 * Memory allocated with ::cuMemAllocManaged should be released with ::cuMemFree.
 *
 * Device memory oversubscription is possible for GPUs that have a non-zero value for the
 * device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS. Managed memory on
 * such GPUs may be evicted from device memory to host memory at any time by the Unified
 * Memory driver in order to make room for other allocations.
 *
 * In a multi-GPU system where all GPUs have a non-zero value for the device attribute
 * ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS, managed memory may not be populated when this
 * API returns and instead may be populated on access. In such systems, managed memory can
 * migrate to any processor's memory at any time. The Unified Memory driver will employ heuristics to
 * maintain data locality and prevent excessive page faults to the extent possible. The application
 * can also guide the driver about memory usage patterns via ::cuMemAdvise. The application
 * can also explicitly migrate memory to a desired processor's memory via
 * ::cuMemPrefetchAsync.
 *
 * In a multi-GPU system where all of the GPUs have a zero value for the device attribute
 * ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS and all the GPUs have peer-to-peer support
 * with each other, the physical storage for managed memory is created on the GPU which is active
 * at the time ::cuMemAllocManaged is called. All other GPUs will reference the data at reduced
 * bandwidth via peer mappings over the PCIe bus. The Unified Memory driver does not migrate
 * memory among such GPUs.
 *
 * In a multi-GPU system where not all GPUs have peer-to-peer support with each other and
 * where the value of the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS
 * is zero for at least one of those GPUs, the location chosen for physical storage of managed
 * memory is system-dependent.
 * - On Linux, the location chosen will be device memory as long as the current set of active
 * contexts are on devices that either have peer-to-peer support with each other or have a
 * non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
 * If there is an active context on a GPU that does not have a non-zero value for that device
 * attribute and it does not have peer-to-peer support with the other devices that have active
 * contexts on them, then the location for physical storage will be 'zero-copy' or host memory.
 * Note that this means that managed memory that is located in device memory is migrated to
 * host memory if a new context is created on a GPU that doesn't have a non-zero value for
 * the device attribute and does not support peer-to-peer with at least one of the other devices
 * that has an active context. This in turn implies that context creation may fail if there is
 * insufficient host memory to migrate all managed allocations.
 * - On Windows, the physical storage is always created in 'zero-copy' or host memory.
 * All GPUs will reference the data at reduced bandwidth over the PCIe bus. In these
 * circumstances, use of the environment variable CUDA_VISIBLE_DEVICES is recommended to
 * restrict CUDA to only use those GPUs that have peer-to-peer support.
 * Alternatively, users can also set CUDA_MANAGED_FORCE_DEVICE_ALLOC to a
 * non-zero value to force the driver to always use device memory for physical storage.
 * When this environment variable is set to a non-zero value, all contexts created in
 * that process on devices that support managed memory have to be peer-to-peer compatible
 * with each other. Context creation will fail if a context is created on a device that
 * supports managed memory and is not peer-to-peer compatible with any of the other
 * managed memory supporting devices on which contexts were previously created, even if
 * those contexts have been destroyed. These environment variables are described
 * in the CUDA programming guide under the "CUDA environment variables" section.

/**
 * \brief Registers an existing host memory range for use by CUDA
 *
 * Page-locks the memory range specified by \p p and \p bytesize and maps it
 * for the device(s) as specified by \p Flags. This memory range also is added
 * to the same tracking mechanism as ::cuMemHostAlloc to automatically accelerate
 * calls to functions such as ::cuMemcpyHtoD(). Since the memory can be accessed
 * directly by the device, it can be read or written with much higher bandwidth
 * than pageable memory that has not been registered.  Page-locking excessive
 * amounts of memory may degrade system performance, since it reduces the amount
 * of memory available to the system for paging. As a result, this function is
 * best used sparingly to register staging areas for data exchange between
 * host and device.
 *
 * The \p Flags parameter enables different options to be specified that
 * affect the allocation, as follows.
 *
 * - ::CU_MEMHOSTREGISTER_PORTABLE: The memory returned by this call will be
 *   considered as pinned memory by all CUDA contexts, not just the one that
 *   performed the allocation.
 *
 * - ::CU_MEMHOSTREGISTER_DEVICEMAP: Maps the allocation into the CUDA address
 *   space. The device pointer to the memory may be obtained by calling
 *   ::cuMemHostGetDevicePointer().
 *
 * - ::CU_MEMHOSTREGISTER_IOMEMORY: The pointer is treated as pointing to some
 *   I/O memory space, e.g. the PCI Express resource of a 3rd party device.
 *
 * - ::CU_MEMHOSTREGISTER_READ_ONLY: The pointer is treated as pointing to memory
 *   that is considered read-only by the device.  On platforms without
 *   ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES, this flag is
 *   required in order to register memory mapped to the CPU as read-only.  Support
 *   for the use of this flag can be queried from the device attribute
 *   ::CU_DEVICE_ATTRIBUTE_READ_ONLY_HOST_REGISTER_SUPPORTED.  Using this flag with
 *   a current context associated with a device that does not have this attribute
 *   set will cause ::cuMemHostRegister to error with CUDA_ERROR_NOT_SUPPORTED.
 *
 * All of these flags are orthogonal to one another: a developer may page-lock
 * memory that is portable or mapped with no restrictions.
 *
 * The ::CU_MEMHOSTREGISTER_DEVICEMAP flag may be specified on CUDA contexts for
 * devices that do not support mapped pinned memory. The failure is deferred
 * to ::cuMemHostGetDevicePointer() because the memory may be mapped into
 * other CUDA contexts via the ::CU_MEMHOSTREGISTER_PORTABLE flag.
 *
 * For devices that have a non-zero value for the device attribute
 * ::CU_DEVICE_ATTRIBUTE_CAN_USE_HOST_POINTER_FOR_REGISTERED_MEM, the memory
 * can also be accessed from the device using the host pointer \p p.
 * The device pointer returned by ::cuMemHostGetDevicePointer() may or may not
 * match the original host pointer \p ptr and depends on the devices visible to the
 * application. If all devices visible to the application have a non-zero value for the
 * device attribute, the device pointer returned by ::cuMemHostGetDevicePointer()
 * will match the original pointer \p ptr. If any device visible to the application
 * has a zero value for the device attribute, the device pointer returned by
 * ::cuMemHostGetDevicePointer() will not match the original host pointer \p ptr,
 * but it will be suitable for use on all devices provided Unified Virtual Addressing
 * is enabled. In such systems, it is valid to access the memory using either pointer
 * on devices that have a non-zero value for the device attribute. Note however that
 * such devices should access the memory using only of the two pointers and not both.

 * CUDA array (in elements); the following types of CUDA arrays can be allocated:
 *     - A 1D mipmapped array is allocated if \p Height and \p Depth extents are both zero.
 *     - A 2D mipmapped array is allocated if only \p Depth extent is zero.
 *     - A 3D mipmapped array is allocated if all three extents are non-zero.
 *     - A 1D layered CUDA mipmapped array is allocated if only \p Height is zero and the
 *       ::CUDA_ARRAY3D_LAYERED flag is set. Each layer is a 1D array. The number
 *       of layers is determined by the depth extent.
 *     - A 2D layered CUDA mipmapped array is allocated if all three extents are non-zero and
 *       the ::CUDA_ARRAY3D_LAYERED flag is set. Each layer is a 2D array. The number
 *       of layers is determined by the depth extent.
 *     - A cubemap CUDA mipmapped array is allocated if all three extents are non-zero and the
 *       ::CUDA_ARRAY3D_CUBEMAP flag is set. \p Width must be equal to \p Height, and
 *       \p Depth must be six. A cubemap is a special type of 2D layered CUDA array,
 *       where the six layers represent the six faces of a cube. The order of the six
 *       layers in memory is the same as that listed in ::CUarray_cubemap_face.
 *     - A cubemap layered CUDA mipmapped array is allocated if all three extents are non-zero,
 *       and both, ::CUDA_ARRAY3D_CUBEMAP and ::CUDA_ARRAY3D_LAYERED flags are set.
 *       \p Width must be equal to \p Height, and \p Depth must be a multiple of six.
 *       A cubemap layered CUDA array is a special type of 2D layered CUDA array that
 *       consists of a collection of cubemaps. The first six layers represent the first
 *       cubemap, the next six layers form the second cubemap, and so on.
 *
 * - ::Format specifies the format of the elements; ::CUarray_format is
 * defined as:
 * \code
    typedef enum CUarray_format_enum {
        CU_AD_FORMAT_UNSIGNED_INT8 = 0x01,

        CU_AD_FORMAT_FLOAT = 0x20
    } CUarray_format;
 *  \endcode
 *
 * - \p NumChannels specifies the number of packed components per CUDA array
 * element; it may be 1, 2, or 4;
 *
 * - ::Flags may be set to
 *   - ::CUDA_ARRAY3D_LAYERED to enable creation of layered CUDA mipmapped arrays. If this flag is set,
 *     \p Depth specifies the number of layers, not the depth of a 3D array.
 *   - ::CUDA_ARRAY3D_SURFACE_LDST to enable surface references to be bound to individual mipmap levels of
 *     the CUDA mipmapped array. If this flag is not set, ::cuSurfRefSetArray will fail when attempting to
 *     bind a mipmap level of the CUDA mipmapped array to a surface reference.
  *   - ::CUDA_ARRAY3D_CUBEMAP to enable creation of mipmapped cubemaps. If this flag is set, \p Width must be
 *     equal to \p Height, and \p Depth must be six. If the ::CUDA_ARRAY3D_LAYERED flag is also set,
 *     then \p Depth must be a multiple of six.
 *   - ::CUDA_ARRAY3D_TEXTURE_GATHER to indicate that the CUDA mipmapped array will be used for texture gather.
 *     Texture gather can only be performed on 2D CUDA mipmapped arrays.
 *
 * \p Width, \p Height and \p Depth must meet certain size requirements as listed in the following table.
 * All values are specified in elements. Note that for brevity's sake, the full name of the device attribute
 * is not specified. For ex., TEXTURE1D_MIPMAPPED_WIDTH refers to the device attribute
 * ::CU_DEVICE_ATTRIBUTE_MAXIMUM_TEXTURE1D_MIPMAPPED_WIDTH.

 * \section CUDA_MALLOC_ASYNC_overview overview
 *
 * The asynchronous allocator allows the user to allocate and free in stream order.

 * outside of the promised stream order, a use before allocation / use after free error
 * will cause undefined behavior.
 *
 * The allocator is free to reallocate the memory as long as it can guarantee
 * that compliant memory accesses will not overlap temporally.
 * The allocator may refer to internal stream ordering as well as inter-stream dependencies
 * (such as CUDA events and null stream dependencies) when establishing the temporal guarantee.
 * The allocator may also insert inter-stream dependencies to establish the temporal guarantee. 
 *
 * \section CUDA_MALLOC_ASYNC_support Supported Platforms

/**
 * \defgroup CUDA_UNIFIED Unified Addressing
 *
 * ___MANBRIEF___ unified addressing functions of the low-level CUDA driver
 * API (___CURRENT_FILE___) ___ENDMANBRIEF___
 *
 * This section describes the unified addressing functions of the
 * low-level CUDA driver application programming interface.
 *
 * @{
 *
 * \section CUDA_UNIFIED_overview Overview
 *
 * CUDA devices can share a unified address space with the host.
 * For these devices there is no distinction between a device
 * pointer and a host pointer -- the same pointer value may be
 * used to access memory from the host program and from a kernel
 * running on the device (with exceptions enumerated below).
 *
 * \section CUDA_UNIFIED_support Supported Platforms
 *
 * Whether or not a device supports unified addressing may be
 * queried by calling ::cuDeviceGetAttribute() with the device
 * attribute ::CU_DEVICE_ATTRIBUTE_UNIFIED_ADDRESSING.
 *
 * Unified addressing is automatically enabled in 64-bit processes
 *
 * \section CUDA_UNIFIED_lookup Looking Up Information from Pointer Values
 *
 * It is possible to look up information about the memory which backs a
 * pointer value.  For instance, one may want to know if a pointer points
 * to host or device memory.  As another example, in the case of device
 * memory, one may want to know on which CUDA device the memory
 * resides.  These properties may be queried using the function
 * ::cuPointerGetAttribute()
 *
 * Since pointers are unique, it is not necessary to specify information
 * about the pointers specified to the various copy functions in the
 * CUDA API.  The function ::cuMemcpy() may be used to perform a copy
 * between two pointers, ignoring whether they point to host or device
 * memory (making ::cuMemcpyHtoD(), ::cuMemcpyDtoD(), and ::cuMemcpyDtoH()
 * unnecessary for devices supporting unified addressing).  For
 * multidimensional copies, the memory type ::CU_MEMORYTYPE_UNIFIED may be
 * used to specify that the CUDA driver should infer the location of the
 * pointer from its value.
 *
 * \section CUDA_UNIFIED_automaphost Automatic Mapping of Host Allocated Host Memory
 *
 * All host memory allocated in all contexts using ::cuMemAllocHost() and
 * ::cuMemHostAlloc() is always directly accessible from all contexts on
 * all devices that support unified addressing.  This is the case regardless
 * of whether or not the flags ::CU_MEMHOSTALLOC_PORTABLE and
 * ::CU_MEMHOSTALLOC_DEVICEMAP are specified.
 *
 * The pointer value through which allocated host memory may be accessed
 * in kernels on all devices that support unified addressing is the same
 * as the pointer value through which that memory is accessed on the host,
 * so it is not necessary to call ::cuMemHostGetDevicePointer() to get the device
 * pointer for these allocations.
 *
 * Note that this is not the case for memory allocated using the flag
 * ::CU_MEMHOSTALLOC_WRITECOMBINED, as discussed below.
 *
 * \section CUDA_UNIFIED_autopeerregister Automatic Registration of Peer Memory
 *
 * Upon enabling direct access from a context that supports unified addressing
 * to another peer context that supports unified addressing using
 * ::cuCtxEnablePeerAccess() all memory allocated in the peer context using
 * ::cuMemAlloc() and ::cuMemAllocPitch() will immediately be accessible
 * by the current context.  The device pointer value through
 * which any peer memory may be accessed in the current context
 * is the same pointer value through which that memory may be
 * accessed in the peer context.
 *
 * \section CUDA_UNIFIED_exceptions Exceptions, Disjoint Addressing
 *
 * Not all memory may be accessed on devices through the same pointer
 * value through which they are accessed on the host.  These exceptions
 * are host memory registered using ::cuMemHostRegister() and host memory
 * allocated using the flag ::CU_MEMHOSTALLOC_WRITECOMBINED.  For these
 * exceptions, there exists a distinct host and device address for the
 * memory.  The device address is guaranteed to not overlap any valid host
 * pointer range and is guaranteed to have the same value across all
 * contexts that support unified addressing.
 *
 * This device address may be queried using ::cuMemHostGetDevicePointer()
 * when a context using unified addressing is current.  Either the host
 * or the unified device pointer value may be used to refer to this memory
 * through ::cuMemcpy() and similar functions using the
 * ::CU_MEMORYTYPE_UNIFIED memory type.
 *

/**
 * \brief Returns information about a pointer
 *
 * The supported attributes are:
 *
 * - ::CU_POINTER_ATTRIBUTE_CONTEXT:
 *
 *      Returns in \p *data the ::CUcontext in which \p ptr was allocated or
 *      registered.
 *      The type of \p data must be ::CUcontext *.
 *
 *      If \p ptr was not allocated by, mapped by, or registered with
 *      a ::CUcontext which uses unified virtual addressing then
 *      ::CUDA_ERROR_INVALID_VALUE is returned.
 *
 * - ::CU_POINTER_ATTRIBUTE_MEMORY_TYPE:
 *
 *      Returns in \p *data the physical memory type of the memory that
 *      \p ptr addresses as a ::CUmemorytype enumerated value.
 *      The type of \p data must be unsigned int.
 *
 *      If \p ptr addresses device memory then \p *data is set to
 *      ::CU_MEMORYTYPE_DEVICE.  The particular ::CUdevice on which the
 *      memory resides is the ::CUdevice of the ::CUcontext returned by the
 *      ::CU_POINTER_ATTRIBUTE_CONTEXT attribute of \p ptr.
 *
 *      If \p ptr addresses host memory then \p *data is set to
 *      ::CU_MEMORYTYPE_HOST.
 *
 *      If \p ptr was not allocated by, mapped by, or registered with
 *      a ::CUcontext which uses unified virtual addressing then
 *      ::CUDA_ERROR_INVALID_VALUE is returned.
 *
 *      If the current ::CUcontext does not support unified virtual
 *      addressing then ::CUDA_ERROR_INVALID_CONTEXT is returned.
 *
 * - ::CU_POINTER_ATTRIBUTE_DEVICE_POINTER:
 *
 *      Returns in \p *data the device pointer value through which
 *      \p ptr may be accessed by kernels running in the current
 *      ::CUcontext.
 *      The type of \p data must be CUdeviceptr *.
 *
 *      If there exists no device pointer value through which
 *      kernels running in the current ::CUcontext may access
 *      \p ptr then ::CUDA_ERROR_INVALID_VALUE is returned.
 *
 *      If there is no current ::CUcontext then
 *      ::CUDA_ERROR_INVALID_CONTEXT is returned.
 *
 *      Except in the exceptional disjoint addressing cases discussed
 *      below, the value returned in \p *data will equal the input
 *      value \p ptr.
 *
 * - ::CU_POINTER_ATTRIBUTE_HOST_POINTER:
 *
 *      Returns in \p *data the host pointer value through which
 *      \p ptr may be accessed by by the host program.
 *      The type of \p data must be void **.
 *      If there exists no host pointer value through which
 *      the host program may directly access \p ptr then
 *      ::CUDA_ERROR_INVALID_VALUE is returned.
 *
 *      Except in the exceptional disjoint addressing cases discussed
 *      below, the value returned in \p *data will equal the input
 *      value \p ptr.
 *
 * - ::CU_POINTER_ATTRIBUTE_P2P_TOKENS:
 *
 *      Returns in \p *data two tokens for use with the nv-p2p.h Linux
 *      kernel interface. \p data must be a struct of type
 *      CUDA_POINTER_ATTRIBUTE_P2P_TOKENS.
 *
 *      \p ptr must be a pointer to memory obtained from :cuMemAlloc().
 *      Note that p2pToken and vaSpaceToken are only valid for the
 *      lifetime of the source allocation. A subsequent allocation at
 *      the same address may return completely different tokens.
 *      Querying this attribute has a side effect of setting the attribute
 *      ::CU_POINTER_ATTRIBUTE_SYNC_MEMOPS for the region of memory that
 *      \p ptr points to.
 *
 * - ::CU_POINTER_ATTRIBUTE_SYNC_MEMOPS:
 *
 *      A boolean attribute which when set, ensures that synchronous memory operations
 *      initiated on the region of memory that \p ptr points to will always synchronize.
 *      See further documentation in the section titled "API synchronization behavior"
 *      to learn more about cases when synchronous memory operations can
 *      exhibit asynchronous behavior.
 *
 * - ::CU_POINTER_ATTRIBUTE_BUFFER_ID:
 *
 *      Returns in \p *data a buffer ID which is guaranteed to be unique within the process.
 *      \p data must point to an unsigned long long.
 *
 *      \p ptr must be a pointer to memory obtained from a CUDA memory allocation API.
 *      Every memory allocation from any of the CUDA memory allocation APIs will
 *      have a unique ID over a process lifetime. Subsequent allocations do not reuse IDs
 *      from previous freed allocations. IDs are only unique within a single process.
 *
 *
 * - ::CU_POINTER_ATTRIBUTE_IS_MANAGED:
 *
 *      Returns in \p *data a boolean that indicates whether the pointer points to
 *      managed memory or not.
 *
 *      If \p ptr is not a valid CUDA pointer then ::CUDA_ERROR_INVALID_VALUE is returned.
 *
 * - ::CU_POINTER_ATTRIBUTE_DEVICE_ORDINAL:
 *
 *      Returns in \p *data an integer representing a device ordinal of a device against
 *      which the memory was allocated or registered.
 *
 * - ::CU_POINTER_ATTRIBUTE_IS_LEGACY_CUDA_IPC_CAPABLE:
 *
 *      Returns in \p *data a boolean that indicates if this pointer maps to
 *      an allocation that is suitable for ::cudaIpcGetMemHandle.
 *
 * - ::CU_POINTER_ATTRIBUTE_RANGE_START_ADDR:
 *
 *      Returns in \p *data the starting address for the allocation referenced
 *      by the device pointer \p ptr.  Note that this is not necessarily the
 *      address of the mapped region, but the address of the mappable address
 *      range \p ptr references (e.g. from ::cuMemAddressReserve).
 *
 * - ::CU_POINTER_ATTRIBUTE_RANGE_SIZE:
 *
 *      Returns in \p *data the size for the allocation referenced by the device
 *      pointer \p ptr.  Note that this is not necessarily the size of the mapped
 *      region, but the size of the mappable address range \p ptr references
 *      (e.g. from ::cuMemAddressReserve).  To retrieve the size of the mapped
 *      region, see ::cuMemGetAddressRange
 *
 * - ::CU_POINTER_ATTRIBUTE_MAPPED:
 *
 *      Returns in \p *data a boolean that indicates if this pointer is in a
 *      valid address range that is mapped to a backing allocation.
 *
 * - ::CU_POINTER_ATTRIBUTE_ALLOWED_HANDLE_TYPES:
 *
 *      Returns a bitmask of the allowed handle types for an allocation that may
 *      be passed to ::cuMemExportToShareableHandle.
 * 
 * - ::CU_POINTER_ATTRIBUTE_MEMPOOL_HANDLE:
 * 
 *      Returns in \p *data the handle to the mempool that the allocation was obtained from.
 *
 * \par
 *
 * Note that for most allocations in the unified virtual address space
 * the host and device pointer for accessing the allocation will be the
 * same.  The exceptions to this are
 *  - user memory registered using ::cuMemHostRegister
 *  - host memory allocated using ::cuMemHostAlloc with the
 *    ::CU_MEMHOSTALLOC_WRITECOMBINED flag
 * For these types of allocation there will exist separate, disjoint host
 * and device addresses for accessing the allocation.  In particular
 *  - The host address will correspond to an invalid unmapped device address
 *    (which will result in an exception if accessed from the device)
 *  - The device address will correspond to an invalid unmapped host address
 *    (which will result in an exception if accessed from the host).
 * For these types of allocations, querying ::CU_POINTER_ATTRIBUTE_HOST_POINTER
 * and ::CU_POINTER_ATTRIBUTE_DEVICE_POINTER may be used to retrieve the host
 * and device addresses from either address.

/**
 * \brief Prefetches memory to the specified destination device
 *
 * Prefetches memory to the specified destination device.  \p devPtr is the
 * base device pointer of the memory to be prefetched and \p dstDevice is the
 * destination device. \p count specifies the number of bytes to copy. \p hStream
 * is the stream in which the operation is enqueued. The memory range must refer
 * to managed memory allocated via ::cuMemAllocManaged or declared via __managed__ variables.
 *
 * Passing in CU_DEVICE_CPU for \p dstDevice will prefetch the data to host memory. If
 * \p dstDevice is a GPU, then the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS
 * must be non-zero. Additionally, \p hStream must be associated with a device that has a
 * non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
 *
 * The start address and end address of the memory range will be rounded down and rounded up
 * respectively to be aligned to CPU page size before the prefetch operation is enqueued
 * in the stream.
 *
 * If no physical memory has been allocated for this region, then this memory region
 * will be populated and mapped on the destination device. If there's insufficient
 * memory to prefetch the desired region, the Unified Memory driver may evict pages from other
 * ::cuMemAllocManaged allocations to host memory in order to make room. Device memory
 * allocated using ::cuMemAlloc or ::cuArrayCreate will not be evicted.
 *
 * By default, any mappings to the previous location of the migrated pages are removed and
 * mappings for the new location are only setup on \p dstDevice. The exact behavior however
 * also depends on the settings applied to this memory range via ::cuMemAdvise as described
 * below:
 *
 * If ::CU_MEM_ADVISE_SET_READ_MOSTLY was set on any subset of this memory range,
 * then that subset will create a read-only copy of the pages on \p dstDevice.
 *
 * If ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION was called on any subset of this memory
 * range, then the pages will be migrated to \p dstDevice even if \p dstDevice is not the
 * preferred location of any pages in the memory range.
 *
 * If ::CU_MEM_ADVISE_SET_ACCESSED_BY was called on any subset of this memory range,
 * then mappings to those pages from all the appropriate processors are updated to
 * refer to the new location if establishing such a mapping is possible. Otherwise,
 * those mappings are cleared.
 *
 * Note that this API is not required for functionality and only serves to improve performance
 * by allowing the application to migrate data to a suitable location before it is accessed.
 * Memory accesses to this range are always coherent and are allowed even when the data is
 * actively being migrated.
 *

/**
 * \brief Advise about the usage of a given memory range
 *
 * Advise the Unified Memory subsystem about the usage pattern for the memory range
 * starting at \p devPtr with a size of \p count bytes. The start address and end address of the memory
 * range will be rounded down and rounded up respectively to be aligned to CPU page size before the
 * advice is applied. The memory range must refer to managed memory allocated via ::cuMemAllocManaged
 * or declared via __managed__ variables. The memory range could also refer to system-allocated pageable
 * memory provided it represents a valid, host-accessible region of memory and all additional constraints
 * imposed by \p advice as outlined below are also satisfied. Specifying an invalid system-allocated pageable
 * memory range results in an error being returned.
 *
 * The \p advice parameter can take the following values:
 * - ::CU_MEM_ADVISE_SET_READ_MOSTLY: This implies that the data is mostly going to be read
 * from and only occasionally written to. Any read accesses from any processor to this region will create a
 * read-only copy of at least the accessed pages in that processor's memory. Additionally, if ::cuMemPrefetchAsync
 * is called on this region, it will create a read-only copy of the data on the destination processor.
 * If any processor writes to this region, all copies of the corresponding page will be invalidated
 * except for the one where the write occurred. The \p device argument is ignored for this advice.
 * Note that for a page to be read-duplicated, the accessing processor must either be the CPU or a GPU
 * that has a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
 * Also, if a context is created on a device that does not have the device attribute
 * ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS set, then read-duplication will not occur until
 * all such contexts are destroyed.
 * If the memory region refers to valid system-allocated pageable memory, then the accessing device must
 * have a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS for a read-only
 * copy to be created on that device. Note however that if the accessing device also has a non-zero value for the
 * device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES, then setting this advice
 * will not create a read-only copy when that device accesses this memory region.
 *
 * - ::CU_MEM_ADVISE_UNSET_READ_MOSTLY:  Undoes the effect of ::CU_MEM_ADVISE_SET_READ_MOSTLY and also prevents the
 * Unified Memory driver from attempting heuristic read-duplication on the memory range. Any read-duplicated
 * copies of the data will be collapsed into a single copy. The location for the collapsed
 * copy will be the preferred location if the page has a preferred location and one of the read-duplicated
 * copies was resident at that location. Otherwise, the location chosen is arbitrary.
 *
 * - ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION: This advice sets the preferred location for the
 * data to be the memory belonging to \p device. Passing in CU_DEVICE_CPU for \p device sets the
 * preferred location as host memory. If \p device is a GPU, then it must have a non-zero value for the
 * device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS. Setting the preferred location
 * does not cause data to migrate to that location immediately. Instead, it guides the migration policy
 * when a fault occurs on that memory region. If the data is already in its preferred location and the
 * faulting processor can establish a mapping without requiring the data to be migrated, then
 * data migration will be avoided. On the other hand, if the data is not in its preferred location
 * or if a direct mapping cannot be established, then it will be migrated to the processor accessing
 * it. It is important to note that setting the preferred location does not prevent data prefetching
 * done using ::cuMemPrefetchAsync.
 * Having a preferred location can override the page thrash detection and resolution logic in the Unified
 * Memory driver. Normally, if a page is detected to be constantly thrashing between for example host and device
 * memory, the page may eventually be pinned to host memory by the Unified Memory driver. But
 * if the preferred location is set as device memory, then the page will continue to thrash indefinitely.
 * If ::CU_MEM_ADVISE_SET_READ_MOSTLY is also set on this memory region or any subset of it, then the
 * policies associated with that advice will override the policies of this advice, unless read accesses from
 * \p device will not result in a read-only copy being created on that device as outlined in description for
 * the advice ::CU_MEM_ADVISE_SET_READ_MOSTLY.
 * If the memory region refers to valid system-allocated pageable memory, then \p device must have a non-zero
 * value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS. Additionally, if \p device has
 * a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES,
 * then this call has no effect. Note however that this behavior may change in the future.
 *
 * - ::CU_MEM_ADVISE_UNSET_PREFERRED_LOCATION: Undoes the effect of ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION
 * and changes the preferred location to none.
 *
 * - ::CU_MEM_ADVISE_SET_ACCESSED_BY: This advice implies that the data will be accessed by \p device.
 * Passing in ::CU_DEVICE_CPU for \p device will set the advice for the CPU. If \p device is a GPU, then
 * the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS must be non-zero.
 * This advice does not cause data migration and has no impact on the location of the data per se. Instead,
 * it causes the data to always be mapped in the specified processor's page tables, as long as the
 * location of the data permits a mapping to be established. If the data gets migrated for any reason,
 * the mappings are updated accordingly.
 * This advice is recommended in scenarios where data locality is not important, but avoiding faults is.
 * Consider for example a system containing multiple GPUs with peer-to-peer access enabled, where the
 * data located on one GPU is occasionally accessed by peer GPUs. In such scenarios, migrating data
 * over to the other GPUs is not as important because the accesses are infrequent and the overhead of
 * migration may be too high. But preventing faults can still help improve performance, and so having
 * a mapping set up in advance is useful. Note that on CPU access of this data, the data may be migrated
 * to host memory because the CPU typically cannot access device memory directly. Any GPU that had the
 * ::CU_MEM_ADVISE_SET_ACCESSED_BY flag set for this data will now have its mapping updated to point to the
 * page in host memory.
 * If ::CU_MEM_ADVISE_SET_READ_MOSTLY is also set on this memory region or any subset of it, then the
 * policies associated with that advice will override the policies of this advice. Additionally, if the
 * preferred location of this memory region or any subset of it is also \p device, then the policies
 * associated with ::CU_MEM_ADVISE_SET_PREFERRED_LOCATION will override the policies of this advice.
 * If the memory region refers to valid system-allocated pageable memory, then \p device must have a non-zero
 * value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS. Additionally, if \p device has
 * a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES,
 * then this call has no effect.
 *
 * - ::CU_MEM_ADVISE_UNSET_ACCESSED_BY: Undoes the effect of ::CU_MEM_ADVISE_SET_ACCESSED_BY. Any mappings to
 * the data from \p device may be removed at any time causing accesses to result in non-fatal page faults.
 * If the memory region refers to valid system-allocated pageable memory, then \p device must have a non-zero
 * value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS. Additionally, if \p device has
 * a non-zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS_USES_HOST_PAGE_TABLES,

 *
 * The \p attribute parameter can take the following values:
 * - ::CU_MEM_RANGE_ATTRIBUTE_READ_MOSTLY: If this attribute is specified, \p data will be interpreted
 * as a 32-bit integer, and \p dataSize must be 4. The result returned will be 1 if all pages in the given

 * - ::CU_MEM_RANGE_ATTRIBUTE_PREFERRED_LOCATION: If this attribute is specified, \p data will be
 * interpreted as a 32-bit integer, and \p dataSize must be 4. The result returned will be a GPU device
 * id if all pages in the memory range have that GPU as their preferred location, or it will be CU_DEVICE_CPU
 * if all pages in the memory range have the CPU as their preferred location, or it will be CU_DEVICE_INVALID
 * if either all the pages don't have the same preferred location or some of the pages don't have a

 * - ::CU_MEM_RANGE_ATTRIBUTE_ACCESSED_BY: If this attribute is specified, \p data will be interpreted
 * as an array of 32-bit integers, and \p dataSize must be a non-zero multiple of 4. The result returned
 * will be a list of device ids that had ::CU_MEM_ADVISE_SET_ACCESSED_BY set for that entire memory range.
 * If any device does not have that advice set for the entire memory range, that device will not be included.
 * If \p data is larger than the number of devices that have that advice set for that memory range,

 * (i.e. \p data has 3 elements) and only device 0 has the advice set, then the result returned will be
 * { 0, CU_DEVICE_INVALID, CU_DEVICE_INVALID }. If \p data is smaller than the number of devices that have

 *   <li>Adding device work to any stream does not have the effect of making
 *   the stream active until all preceding host functions and stream callbacks
 *   have executed.  Thus, for
 *   example, a callback might use global attached memory even if work has
 *   been added to another stream, if the work has been ordered behind the
 *   callback with an event.</li>
 *   <li>Completion of a callback does not cause a stream to become
 *   active except as described above.  The callback stream will remain idle
 *   if no device work follows the callback, and will remain idle across
 *   consecutive callbacks without device work in between.  Thus, for example,

/**
 * \brief Attach memory to a stream asynchronously
 *
 * Enqueues an operation in \p hStream to specify stream association of
 * \p length bytes of memory starting from \p dptr. This function is a
 * stream-ordered operation, meaning that it is dependent on, and will
 * only take effect when, previous work in stream has completed. Any
 * previous association is automatically replaced.
 *
 * \p dptr must point to one of the following types of memories:
 * - managed memory declared using the __managed__ keyword or allocated with
 *   ::cuMemAllocManaged.
 * - a valid host-accessible region of system-allocated pageable memory. This
 *   type of memory may only be specified if the device associated with the
 *   stream reports a non-zero value for the device attribute
 *   ::CU_DEVICE_ATTRIBUTE_PAGEABLE_MEMORY_ACCESS.
 *
 * For managed allocations, \p length must be either zero or the entire
 * allocation's size. Both indicate that the entire allocation's stream
 * association is being changed. Currently, it is not possible to change stream
 * association for a portion of a managed allocation.
 *
 * For pageable host allocations, \p length must be non-zero.
 *
 * The stream association is specified using \p flags which must be
 * one of ::CUmemAttach_flags.
 * If the ::CU_MEM_ATTACH_GLOBAL flag is specified, the memory can be accessed
 * by any stream on any device.
 * If the ::CU_MEM_ATTACH_HOST flag is specified, the program makes a guarantee
 * that it won't access the memory on the device from any stream on a device that
 * has a zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS.
 * If the ::CU_MEM_ATTACH_SINGLE flag is specified and \p hStream is associated with
 * a device that has a zero value for the device attribute ::CU_DEVICE_ATTRIBUTE_CONCURRENT_MANAGED_ACCESS,
 * the program makes a guarantee that it will only access the memory on the device
 * from \p hStream. It is illegal to attach singly to the NULL stream, because the
 * NULL stream is a virtual global stream and not a specific stream. An error will
 * be returned in this case.
 *
 * When memory is associated with a single stream, the Unified Memory system will
 * allow CPU access to this memory region so long as all operations in \p hStream
 * have completed, regardless of whether other streams are active. In effect,
 * this constrains exclusive ownership of the managed memory region by
 * an active GPU to per-stream activity instead of whole-GPU activity.
 *
 * Accessing memory on the device from streams that are not associated with
 * it will produce undefined results. No error checking is performed by the
 * Unified Memory system to ensure that kernels launched into other streams
 * do not access this region.
 *
 * It is a program's responsibility to order calls to ::cuStreamAttachMemAsync
 * via events, synchronization or other means to ensure legal access to memory
 * at all times. Data visibility and coherency will be changed appropriately
 * for all kernels which follow a stream-association change.
 *
 * If \p hStream is destroyed while data is associated with it, the association is
 * removed and the association reverts to the default visibility of the allocation
 * as specified at ::cuMemAllocManaged. For __managed__ variables, the default
 * association is always ::CU_MEM_ATTACH_GLOBAL. Note that destroying a stream is an
 * asynchronous operation, and as a result, the change to default association won't
 * happen until all work in the stream has completed.

 * ___MANBRIEF___ Stream memory operations of the low-level CUDA driver API
 * (___CURRENT_FILE___) ___ENDMANBRIEF___
 *
 * This section describes the stream memory operations of the low-level CUDA
 * driver application programming interface.
 *
 * There are two versions of these APIs, a legacy version and a newer V2 version.
 *
 * V1:
 *
 * The V1 API is disabled by default. Users are required
 * to explicitly enable it, e.g. on Linux by passing the kernel module
 * parameter shown below:
 *     modprobe nvidia NVreg_EnableStreamMemOPs=1
 * There is currently no way to enable these operations on other operating
 * systems.
 *
 * Users can programmatically query whether the device supports these
 * operations with ::cuDeviceGetAttribute() and
 * ::CU_DEVICE_ATTRIBUTE_CAN_USE_STREAM_MEM_OPS.
 *
 * Support for the ::CU_STREAM_WAIT_VALUE_NOR flag can be queried with
 * ::CU_DEVICE_ATTRIBUTE_CAN_USE_STREAM_WAIT_VALUE_NOR.
 *
 * Support for the ::cuStreamWriteValue64() and ::cuStreamWaitValue64()
 * functions, as well as for the ::CU_STREAM_MEM_OP_WAIT_VALUE_64 and
 * ::CU_STREAM_MEM_OP_WRITE_VALUE_64 flags, can be queried with
 * ::CU_DEVICE_ATTRIBUTE_CAN_USE_64_BIT_STREAM_MEM_OPS.
 *
 * Support for both ::CU_STREAM_WAIT_VALUE_FLUSH and
 * ::CU_STREAM_MEM_OP_FLUSH_REMOTE_WRITES requires dedicated platform
 * hardware features and can be queried with ::cuDeviceGetAttribute() and
 * ::CU_DEVICE_ATTRIBUTE_CAN_FLUSH_REMOTE_WRITES.
 *
 * V2:
 *
 * The V2 APIs are available by default on all platforms.
 *
 * Support for the ::CU_STREAM_WAIT_VALUE_NOR flag can be queried with
 * ::CU_DEVICE_ATTRIBUTE_CAN_USE_STREAM_WAIT_VALUE_NOR_V2.
 *
 * Support for the ::cuStreamWriteValue64() and ::cuStreamWaitValue64()
 * functions, as well as for the ::CU_STREAM_MEM_OP_WAIT_VALUE_64 and
 * ::CU_STREAM_MEM_OP_WRITE_VALUE_64 flags, can be queried with
 * ::CU_DEVICE_ATTRIBUTE_CAN_USE_64_BIT_STREAM_MEM_OPS_V2.
 *
 * Support for both ::CU_STREAM_WAIT_VALUE_FLUSH and
 * ::CU_STREAM_MEM_OP_FLUSH_REMOTE_WRITES requires dedicated platform
 * hardware features and can be queried with ::cuDeviceGetAttribute() and
 * ::CU_DEVICE_ATTRIBUTE_CAN_FLUSH_REMOTE_WRITES.
 *
 * V1 & V2:
 *
 * Note that all memory pointers passed as parameters to these operations
 * are device pointers. Where necessary a device pointer should be
 * obtained, for example with ::cuMemHostGetDevicePointer().
 *
 * None of the operations accepts pointers to managed memory buffers
 * (::cuMemAllocManaged).
 *
 * \note
 * Warning:
 * Improper use of these APIs may deadlock the application. Synchronization 
 * ordering established through these APIs is not visible to CUDA. CUDA tasks 
 * that are (even indirectly) ordered by these APIs should also have that order
 * expressed with CUDA-visible dependencies such as events. This ensures that 
 * the scheduler does not serialize them in an improper order. For more 
 * information, see the Stream Memory Operations section in the programming 
 * guide(https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html).

/**
 * \brief Wait on a memory location
 *

 * memory is satisfied. By default, the condition is to wait for
 * (int32_t)(*addr - value) >= 0, a cyclic greater-or-equal.
 * Other condition types can be specified via \p flags.
 *
 * If the memory was registered via ::cuMemHostRegister(), the device pointer
 * should be obtained with ::cuMemHostGetDevicePointer(). This function cannot
 * be used with managed memory (::cuMemAllocManaged).

 * \brief Launches a CUDA function
 *
 * Invokes the kernel \p f on a \p gridDimX x \p gridDimY x \p gridDimZ
 * grid of blocks. Each block contains \p blockDimX x \p blockDimY x
 * \p blockDimZ threads.
 *
 * \p sharedMemBytes sets the amount of dynamic shared memory that will be
 * available to each thread block.
 *
 * Kernel parameters to \p f can be specified in one of two ways:
 *
 * 1) Kernel parameters can be specified via \p kernelParams.  If \p f
 * has N parameters, then \p kernelParams needs to be an array of N
 * pointers.  Each of \p kernelParams[0] through \p kernelParams[N-1]
 * must point to a region of memory from which the actual kernel
 * parameter will be copied.  The number of kernel parameters and their
 * offsets and sizes do not need to be specified as that information is
 * retrieved directly from the kernel's image.
 *
 * 2) Kernel parameters can also be packaged by the application into
 * a single buffer that is passed in via the \p extra parameter.
 * This places the burden on the application of knowing each kernel
 * parameter's size and alignment/padding within the buffer.  Here is
 * an example of using the \p extra parameter in this manner:
 * \code
    size_t argBufferSize;
    char argBuffer[256];

    // populate argBuffer and argBufferSize

    void *config[] = {
        CU_LAUNCH_PARAM_BUFFER_POINTER, argBuffer,
        CU_LAUNCH_PARAM_BUFFER_SIZE,    &argBufferSize,
        CU_LAUNCH_PARAM_END
    };
    status = cuLaunchKernel(f, gx, gy, gz, bx, by, bz, sh, s, NULL, config);
 * \endcode
 *
 * The \p extra parameter exists to allow ::cuLaunchKernel to take
 * additional less commonly used arguments.  \p extra specifies a list of
 * names of extra settings and their corresponding values.  Each extra
 * setting name is immediately followed by the corresponding value.  The
 * list must be terminated with either NULL or ::CU_LAUNCH_PARAM_END.
 *
 * - ::CU_LAUNCH_PARAM_END, which indicates the end of the \p extra
 *   array;
 * - ::CU_LAUNCH_PARAM_BUFFER_POINTER, which specifies that the next
 *   value in \p extra will be a pointer to a buffer containing all
 *   the kernel parameters for launching kernel \p f;
 * - ::CU_LAUNCH_PARAM_BUFFER_SIZE, which specifies that the next
 *   value in \p extra will be a pointer to a size_t containing the
 *   size of the buffer specified with ::CU_LAUNCH_PARAM_BUFFER_POINTER;
 *
 * The error ::CUDA_ERROR_INVALID_VALUE will be returned if kernel
 * parameters are specified with both \p kernelParams and \p extra
 * (i.e. both \p kernelParams and \p extra are non-NULL).
 *
 * Calling ::cuLaunchKernel() invalidates the persistent function state
 * set through the following deprecated APIs:
 *  ::cuFuncSetBlockShape(),
 *  ::cuFuncSetSharedSize(),
 *  ::cuParamSetSize(),
 *  ::cuParamSeti(),

/**
 * \brief Launches CUDA functions on multiple devices where thread blocks can cooperate and synchronize as they execute
 *
 * \deprecated This function is deprecated as of CUDA 11.3.
 *
 * Invokes kernels as specified in the \p launchParamsList array where each element
 * of the array specifies all the parameters required to perform a single kernel launch.
 * These kernels can cooperate and synchronize as they execute. The size of the array is
 * specified by \p numDevices.
 *
 * No two kernels can be launched on the same device. All the devices targeted by this
 * multi-device launch must be identical. All devices must have a non-zero value for the
 * device attribute ::CU_DEVICE_ATTRIBUTE_COOPERATIVE_MULTI_DEVICE_LAUNCH.
 *
 * All kernels launched must be identical with respect to the compiled code. Note that
 * any __device__, __constant__ or __managed__ variables present in the module that owns
 * the kernel launched on each device, are independently instantiated on every device.
 * It is the application's responsiblity to ensure these variables are initialized and
 * used appropriately.
 *
 * The size of the grids as specified in blocks, the size of the blocks themselves
 * and the amount of shared memory used by each thread block must also match across
 * all launched kernels.
 *
 * The streams used to launch these kernels must have been created via either ::cuStreamCreate
 * or ::cuStreamCreateWithPriority. The NULL stream or ::CU_STREAM_LEGACY or ::CU_STREAM_PER_THREAD
 * cannot be used.
 *
 * The total number of blocks launched per kernel cannot exceed the maximum number of blocks
 * per multiprocessor as returned by ::cuOccupancyMaxActiveBlocksPerMultiprocessor (or
 * ::cuOccupancyMaxActiveBlocksPerMultiprocessorWithFlags) times the number of multiprocessors
 * as specified by the device attribute ::CU_DEVICE_ATTRIBUTE_MULTIPROCESSOR_COUNT. Since the
 * total number of blocks launched per device has to match across all devices, the maximum
 * number of blocks that can be launched per device will be limited by the device with the
 * least number of multiprocessors.
 *
 * The kernels cannot make use of CUDA dynamic parallelism.
 *
 * The ::CUDA_LAUNCH_PARAMS structure is defined as:
 * \code
        typedef struct CUDA_LAUNCH_PARAMS_st
        {
            CUfunction function;
            unsigned int gridDimX;

            CUstream hStream;
            void **kernelParams;
        } CUDA_LAUNCH_PARAMS;
 * \endcode
 * where:
 * - ::CUDA_LAUNCH_PARAMS::function specifies the kernel to be launched. All functions must
 *   be identical with respect to the compiled code.
 * - ::CUDA_LAUNCH_PARAMS::gridDimX is the width of the grid in blocks. This must match across
 *   all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::gridDimY is the height of the grid in blocks. This must match across
 *   all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::gridDimZ is the depth of the grid in blocks. This must match across
 *   all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::blockDimX is the X dimension of each thread block. This must match across
 *   all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::blockDimX is the Y dimension of each thread block. This must match across
 *   all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::blockDimZ is the Z dimension of each thread block. This must match across
 *   all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::sharedMemBytes is the dynamic shared-memory size per thread block in bytes.
 *   This must match across all kernels launched.
 * - ::CUDA_LAUNCH_PARAMS::hStream is the handle to the stream to perform the launch in. This cannot
 *   be the NULL stream or ::CU_STREAM_LEGACY or ::CU_STREAM_PER_THREAD. The CUDA context associated
 *   with this stream must match that associated with ::CUDA_LAUNCH_PARAMS::function.
 * - ::CUDA_LAUNCH_PARAMS::kernelParams is an array of pointers to kernel parameters. If
 *   ::CUDA_LAUNCH_PARAMS::function has N parameters, then ::CUDA_LAUNCH_PARAMS::kernelParams
 *   needs to be an array of N pointers. Each of ::CUDA_LAUNCH_PARAMS::kernelParams[0] through
 *   ::CUDA_LAUNCH_PARAMS::kernelParams[N-1] must point to a region of memory from which the actual
 *   kernel parameter will be copied. The number of kernel parameters and their offsets and sizes
 *   do not need to be specified as that information is retrieved directly from the kernel's image.
 *
 * By default, the kernel won't begin execution on any GPU until all prior work in all the specified
 * streams has completed. This behavior can be overridden by specifying the flag
 * ::CUDA_COOPERATIVE_LAUNCH_MULTI_DEVICE_NO_PRE_LAUNCH_SYNC. When this flag is specified, each kernel
 * will only wait for prior work in the stream corresponding to that GPU to complete before it begins
 * execution.
 *
 * Similarly, by default, any subsequent work pushed in any of the specified streams will not begin
 * execution until the kernels on all GPUs have completed. This behavior can be overridden by specifying
 * the flag ::CUDA_COOPERATIVE_LAUNCH_MULTI_DEVICE_NO_POST_LAUNCH_SYNC. When this flag is specified,
 * any subsequent work pushed in any of the specified streams will only wait for the kernel launched
 * on the GPU corresponding to that stream to complete before it begins execution.
 *
 * Calling ::cuLaunchCooperativeKernelMultiDevice() sets persistent function state that is
 * the same as function state set through ::cuLaunchKernel API when called individually for each
 * element in \p launchParamsList.

/**
 * \brief Enqueues a host function call in a stream
 *
 * Enqueues a host function to run in a stream.  The function will be called
 * after currently enqueued work and will block work added after it.
 *
 * The host function must not make any CUDA API calls.  Attempting to use a
 * CUDA API may result in ::CUDA_ERROR_NOT_PERMITTED, but this is not required.
 * The host function must not perform any synchronization that may depend on
 * outstanding CUDA work not mandated to run earlier.  Host functions without a
 * mandated order (such as in independent streams) execute in undefined order
 * and may be serialized.
 *
 * For the purposes of Unified Memory, execution makes a number of guarantees:
 * <ul>
 *   <li>The stream is considered idle for the duration of the function's
 *   execution.  Thus, for example, the function may always use memory attached
 *   to the stream it was enqueued in.</li>
 *   <li>The start of execution of the function has the same effect as
 *   synchronizing an event recorded in the same stream immediately prior to
 *   the function.  It thus synchronizes streams which have been "joined"
 *   prior to the function.</li>
 *   <li>Adding device work to any stream does not have the effect of making
 *   the stream active until all preceding host functions and stream callbacks
 *   have executed.  Thus, for
 *   example, a function might use global attached memory even if work has
 *   been added to another stream, if the work has been ordered behind the
 *   function call with an event.</li>
 *   <li>Completion of the function does not cause a stream to become
 *   active except as described above.  The stream will remain idle
 *   if no device work follows the function, and will remain idle across
 *   consecutive host functions or stream callbacks without device work in
 *   between.  Thus, for example,
 *   stream synchronization can be done by signaling from a host function at the
 *   end of the stream.</li>

 * It is possible for \p numDependencies to be 0, in which case the node will be placed
 * at the root of the graph. \p dependencies may not have any duplicate entries.
 * A handle to the new node will be returned in \p phGraphNode.
 *
 * The CUDA_KERNEL_NODE_PARAMS structure is defined as:
 *
 * \code
 *  typedef struct CUDA_KERNEL_NODE_PARAMS_st {
 *      CUfunction func;
 *      unsigned int gridDimX;
 *      unsigned int gridDimY;
 *      unsigned int gridDimZ;
 *      unsigned int blockDimX;
 *      unsigned int blockDimY;
 *      unsigned int blockDimZ;
 *      unsigned int sharedMemBytes;
 *      void **kernelParams;
 *      void **extra;
 *  } CUDA_KERNEL_NODE_PARAMS;
 * \endcode
 *
 * When the graph is launched, the node will invoke kernel \p func on a (\p gridDimX x
 * \p gridDimY x \p gridDimZ) grid of blocks. Each block contains
 * (\p blockDimX x \p blockDimY x \p blockDimZ) threads.
 *
 * \p sharedMemBytes sets the amount of dynamic shared memory that will be
 * available to each thread block.
 *
 * Kernel parameters to \p func can be specified in one of two ways:
 *
 * 1) Kernel parameters can be specified via \p kernelParams. If the kernel has N
 * parameters, then \p kernelParams needs to be an array of N pointers. Each pointer,
 * from \p kernelParams[0] to \p kernelParams[N-1], points to the region of memory from which the actual
 * parameter will be copied. The number of kernel parameters and their offsets and sizes do not need
 * to be specified as that information is retrieved directly from the kernel's image.
 *
 * 2) Kernel parameters for non-cooperative kernels can also be packaged by the application into a single
 * buffer that is passed in via \p extra. This places the burden on the application of knowing each
 * kernel parameter's size and alignment/padding within the buffer. The \p extra parameter exists
 * to allow this function to take additional less commonly used arguments. \p extra specifies
 * a list of names of extra settings and their corresponding values. Each extra setting name is
 * immediately followed by the corresponding value. The list must be terminated with either NULL or
 * CU_LAUNCH_PARAM_END.
 *
 * - ::CU_LAUNCH_PARAM_END, which indicates the end of the \p extra
 *   array;
 * - ::CU_LAUNCH_PARAM_BUFFER_POINTER, which specifies that the next
 *   value in \p extra will be a pointer to a buffer
 *   containing all the kernel parameters for launching kernel
 *   \p func;
 * - ::CU_LAUNCH_PARAM_BUFFER_SIZE, which specifies that the next
 *   value in \p extra will be a pointer to a size_t
 *   containing the size of the buffer specified with
 *   ::CU_LAUNCH_PARAM_BUFFER_POINTER;
 *
 * The error ::CUDA_ERROR_INVALID_VALUE will be returned if kernel parameters are specified with both
 * \p kernelParams and \p extra (i.e. both \p kernelParams and \p extra are non-NULL).
 * ::CUDA_ERROR_INVALID_VALUE will be returned if \p extra is used for a cooperative kernel.
 *
 * The \p kernelParams or \p extra array, as well as the argument values it points to,
 * are copied during this call.
 *
 * \note Kernels launched using graphs must not use texture and surface references. Reading or
 *       writing through any texture or surface reference is undefined behavior.
 *       This restriction does not apply to texture and surface objects.

 *
 * Limitations:
 *
 * - Kernel nodes:
 *   - The owning context of the function cannot change.
 *   - A node whose function originally did not use CUDA dynamic parallelism cannot be updated
 *     to a function which uses CDP.
 *   - A cooperative node cannot be updated to a non-cooperative node, and vice-versa.
 *   - If the graph was instantiated with CUDA_GRAPH_INSTANTIATE_FLAG_USE_NODE_PRIORITY, the
 *     priority attribute cannot change. Equality is checked on the originally requested
 *     priority values, before they are clamped to the device's supported range.
 * - Memset and memcpy nodes:
 *   - The CUDA device(s) to which the operand(s) was allocated/mapped cannot change.
 *   - The source/destination memory must be allocated from the same contexts as the original
 *     source/destination memory.
 *   - Only 1D memsets can be changed.
 * - Additional memcpy node restrictions:
 *   - Changing either the source or destination memory type(i.e. CU_MEMORYTYPE_DEVICE,
 *     CU_MEMORYTYPE_ARRAY, etc.) is not supported.
 * - External semaphore wait nodes and record nodes:
 *   - Changing the number of semaphores is not supported.
 *
 * Note:  The API may add further restrictions in future releases.  The return code should always be checked.
 *
 * cuGraphExecUpdate sets \p updateResult_out to CU_GRAPH_EXEC_UPDATE_ERROR_TOPOLOGY_CHANGED under
 * the following conditions:
 *
 * - The count of nodes directly in \p hGraphExec and \p hGraph differ, in which case \p hErrorNode_out
 *   is NULL.
 * - A node is deleted in \p hGraph but not not its pair from \p hGraphExec, in which case \p hErrorNode_out
 *   is NULL.
 * - A node is deleted in \p hGraphExec but not its pair from \p hGraph, in which case \p hErrorNode_out is
 *   the pairless node from \p hGraph.
 * - The dependent nodes of a pair differ, in which case \p hErrorNode_out is the node from \p hGraph.
 *
 * cuGraphExecUpdate sets \p updateResult_out to:
 * - CU_GRAPH_EXEC_UPDATE_ERROR if passed an invalid value.
 * - CU_GRAPH_EXEC_UPDATE_ERROR_TOPOLOGY_CHANGED if the graph topology changed
 * - CU_GRAPH_EXEC_UPDATE_ERROR_NODE_TYPE_CHANGED if the type of a node changed, in which case
 *   \p hErrorNode_out is set to the node from \p hGraph.
 * - CU_GRAPH_EXEC_UPDATE_ERROR_UNSUPPORTED_FUNCTION_CHANGE if the function changed in an unsupported
 *   way(see note above), in which case \p hErrorNode_out is set to the node from \p hGraph
 * - CU_GRAPH_EXEC_UPDATE_ERROR_PARAMETERS_CHANGED if any parameters to a node changed in a way 
 *   that is not supported, in which case \p hErrorNode_out is set to the node from \p hGraph.
 * - CU_GRAPH_EXEC_UPDATE_ERROR_ATTRIBUTES_CHANGED if any attributes of a node changed in a way
 *   that is not supported, in which case \p hErrorNode_out is set to the node from \p hGraph.
 * - CU_GRAPH_EXEC_UPDATE_ERROR_NOT_SUPPORTED if something about a node is unsupported, like 
 *   the node's type or configuration, in which case \p hErrorNode_out is set to the node from \p hGraph
 *
 * If \p updateResult_out isn't set in one of the situations described above, the update check passes
 * and cuGraphExecUpdate updates \p hGraphExec to match the contents of \p hGraph.  If an error happens
 * during the update, \p updateResult_out will be set to CU_GRAPH_EXEC_UPDATE_ERROR; otherwise,
 * \p updateResult_out is set to CU_GRAPH_EXEC_UPDATE_SUCCESS.
 *

 *   for CUDA mipmapped arrays, this flag has to be set.
 *   - ::CU_TRSF_DISABLE_TRILINEAR_OPTIMIZATION, which disables any trilinear
 *   filtering optimizations. Trilinear optimizations improve texture filtering
 *   performance by allowing bilinear filtering on textures in scenarios where
 *   it can closely approximate the expected results.
 *   - ::CU_TRSF_SEAMLESS_CUBEMAP, which enables seamless cube map filtering. 
 *   This flag can only be specified if the underlying resource is a CUDA array 
 *   or a CUDA mipmapped array that was created with the flag ::CUDA_ARRAY3D_CUBEMAP.
 *   When seamless cube map filtering is enabled, texture address modes specified 
 *   by ::CUDA_TEXTURE_DESC::addressMode are ignored. Instead, if the ::CUDA_TEXTURE_DESC::filterMode 
 *   is set to ::CU_TR_FILTER_MODE_POINT the address mode ::CU_TR_ADDRESS_MODE_CLAMP 
 *   will be applied for all dimensions. If the ::CUDA_TEXTURE_DESC::filterMode is 
 *   set to ::CU_TR_FILTER_MODE_LINEAR seamless cube map filtering will be performed
 *   when sampling along the cube face borders.
 *
 * - ::CUDA_TEXTURE_DESC::maxAnisotropy specifies the maximum anisotropy ratio to be used when doing anisotropic filtering. This value will be
 *   clamped to the range [1,16].
 *
 * - ::CUDA_TEXTURE_DESC::mipmapFilterMode specifies the filter mode when the calculated mipmap level lies between two defined mipmap levels.
 *
 * - ::CUDA_TEXTURE_DESC::mipmapLevelBias specifies the offset to be applied to the calculated mipmap level.
 *
 * - ::CUDA_TEXTURE_DESC::minMipmapLevelClamp specifies the lower end of the mipmap level range to clamp access to.
 *
 * - ::CUDA_TEXTURE_DESC::maxMipmapLevelClamp specifies the upper end of the mipmap level range to clamp access to.
 *
 *
 * The ::CUDA_RESOURCE_VIEW_DESC struct is defined as
 * \code
        typedef struct CUDA_RESOURCE_VIEW_DESC_st
        {
            CUresourceViewFormat format;
            size_t width;
            size_t height;
            size_t depth;
            unsigned int firstMipmapLevel;
            unsigned int lastMipmapLevel;
            unsigned int firstLayer;
            unsigned int lastLayer;
        } CUDA_RESOURCE_VIEW_DESC;
 * \endcode
 * where:
 * - ::CUDA_RESOURCE_VIEW_DESC::format specifies how the data contained in the CUDA array or CUDA mipmapped array should
 *   be interpreted. Note that this can incur a change in size of the texture data. If the resource view format is a block
 *   compressed format, then the underlying CUDA array or CUDA mipmapped array has to have a base of format ::CU_AD_FORMAT_UNSIGNED_INT32.
 *   with 2 or 4 channels, depending on the block compressed format. For ex., BC1 and BC4 require the underlying CUDA array to have
 *   a format of ::CU_AD_FORMAT_UNSIGNED_INT32 with 2 channels. The other BC formats require the underlying resource to have the same base
 *   format but with 4 channels.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::width specifies the new width of the texture data. If the resource view format is a block
 *   compressed format, this value has to be 4 times the original width of the resource. For non block compressed formats,
 *   this value has to be equal to that of the original resource.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::height specifies the new height of the texture data. If the resource view format is a block
 *   compressed format, this value has to be 4 times the original height of the resource. For non block compressed formats,
 *   this value has to be equal to that of the original resource.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::depth specifies the new depth of the texture data. This value has to be equal to that of the
 *   original resource.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::firstMipmapLevel specifies the most detailed mipmap level. This will be the new mipmap level zero.
 *   For non-mipmapped resources, this value has to be zero.::CUDA_TEXTURE_DESC::minMipmapLevelClamp and ::CUDA_TEXTURE_DESC::maxMipmapLevelClamp
 *   will be relative to this value. For ex., if the firstMipmapLevel is set to 2, and a minMipmapLevelClamp of 1.2 is specified,
 *   then the actual minimum mipmap level clamp will be 3.2.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::lastMipmapLevel specifies the least detailed mipmap level. For non-mipmapped resources, this value
 *   has to be zero.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::firstLayer specifies the first layer index for layered textures. This will be the new layer zero.
 *   For non-layered resources, this value has to be zero.
 *
 * - ::CUDA_RESOURCE_VIEW_DESC::lastLayer specifies the last layer index for layered textures. For non-layered resources,
 *   this value has to be zero.

/**
 * \brief Returns the requested driver API function pointer
 *
 * Returns in \p **pfn the address of the CUDA driver function for the requested
 * CUDA version and flags.
 *
 * The CUDA version is specified as (1000 * major + 10 * minor), so CUDA 11.2
 * should be specified as 11020. For a requested driver symbol, if the specified
 * CUDA version is greater than or equal to the CUDA version in which the driver symbol
 * was introduced, this API will return the function pointer to the corresponding
 * versioned function.
 *
 * The pointer returned by the API should be cast to a function pointer matching the
 * requested driver function's definition in the API header file. The function pointer
 * typedef can be picked up from the corresponding typedefs header file. For example,
 * cudaTypedefs.h consists of function pointer typedefs for driver APIs defined in cuda.h.
 *
 * The API will return ::CUDA_ERROR_NOT_FOUND if the requested driver function is not
 * supported on the platform, no ABI compatible driver function exists for the specified
 * \p cudaVersion or if the driver symbol is invalid.
 *
 * The requested flags can be:
 * - ::CU_GET_PROC_ADDRESS_DEFAULT: This is the default mode. This is equivalent to
 *   ::CU_GET_PROC_ADDRESS_PER_THREAD_DEFAULT_STREAM if the code is compiled with
 *   --default-stream per-thread compilation flag or the macro CUDA_API_PER_THREAD_DEFAULT_STREAM
 *   is defined; ::CU_GET_PROC_ADDRESS_LEGACY_STREAM otherwise.
 * - ::CU_GET_PROC_ADDRESS_LEGACY_STREAM: This will enable the search for all driver symbols
 *   that match the requested driver symbol name except the corresponding per-thread versions.
 * - ::CU_GET_PROC_ADDRESS_PER_THREAD_DEFAULT_STREAM: This will enable the search for all
 *   driver symbols that match the requested driver symbol name including the per-thread
 *   versions. If a per-thread version is not found, the API will return the legacy version
 *   of the driver function.
 *
 * \param symbol - The base name of the driver API function to look for. As an example,
 *                 for the driver API ::cuMemAlloc_v2, \p symbol would be cuMemAlloc and
 *                 \p cudaVersion would be the ABI compatible CUDA version for the _v2 variant. 
 * \param pfn - Location to return the function pointer to the requested driver function
 * \param cudaVersion - The CUDA version to look for the requested driver symbol 
 * \param flags -  Flags to specify search options.
 *
 * \return
 * ::CUDA_SUCCESS,
 * ::CUDA_ERROR_INVALID_VALUE,
 * ::CUDA_ERROR_NOT_SUPPORTED,
 * ::CUDA_ERROR_NOT_FOUND
 * \note_version_mixing
 *
 * \sa

/* 
* @brief Retrieve handle for an address range 
* 
* Get a handle of the specified type to an address range. The address range
* must have been obtained by a prior call to either ::cuMemAlloc or ::cuMemAddressReserve.
* If the address range was obtained via ::cuMemAddressReserve, it must also be fully mapped via ::cuMemMap.
* 
* Users must ensure the \p dptr and \p size are aligned to the host page size.
* 
* When requesting CUmemRangeHandleType::CU_MEM_RANGE_HANDLE_TYPE_DMA_BUF_FD,
* users are expected to query for dma_buf support for the platform
* by using ::CU_DEVICE_ATTRIBUTE_DMA_BUF_SUPPORTED device attribute before calling
* this API. The \p handle will be interpreted as a pointer to an integer to store the dma_buf file descriptor.
* Users must ensure the entire address range is backed and mapped when
* the address range is allocated by ::cuMemAddressReserve. All the physical
* allocations backing the address range must be resident on the same device and
* have identical allocation properties. Users are also expected to retrieve a
* new handle every time the underlying physical allocation(s) corresponding
* to a previously queried VA range are changed.
* 
* @param[out] handle     - Pointer to the location where the returned handle will be stored. 
* @param[in] dptr        - Pointer to a valid CUDA device allocation. Must be aligned to host page size.
* @param[in] size        - Length of the address range. Must be aligned to host page size.
* @param[in] handleType  - Type of handle requested (defines type and size of the \p handle output parameter)
* @param[in] flags       - Reserved, must be zero 
* 
* @returns
* CUDA_SUCCESS 
* CUDA_ERROR_INVALID_VALUE
