-/**
- * \brief Create a CUDA context with execution affinity
- *
- * Creates a new CUDA context with execution affinity and associates it with
- * the calling thread. The \p paramsArray and \p flags parameter are described below.
- * The context is created with a usage count of 1 and the caller of ::cuCtxCreate() must
- * call ::cuCtxDestroy() or when done using the context. If a context is already
- * current to the thread, it is supplanted by the newly created context and may
- * be restored by a subsequent call to ::cuCtxPopCurrent().
- *
- * The type and the amount of execution resource the context can use is limited by \p paramsArray
- * and \p numParams. The \p paramsArray is an array of \p CUexecAffinityParam and the \p numParams
- * describes the size of the array. If two \p CUexecAffinityParam in the array have the same type,
- * the latter execution affinity parameter overrides the former execution affinity parameter.
- * The supported execution affinity types are:
- * - ::CU_EXEC_AFFINITY_TYPE_SM_COUNT limits the portion of SMs that the context can use. The portion
- * of SMs is specified as the number of SMs via \p CUexecAffinitySmCount. This limit will be internally
- * rounded up to the next hardware-supported amount. Hence, it is imperative to query the actual execution
- * affinity of the context via \p cuCtxGetExecAffinity after context creation. Currently, this attribute
- * is only supported under Volta+ MPS.
- *
- * The three LSBs of the \p flags parameter can be used to control how the OS
- * thread, which owns the CUDA context at the time of an API call, interacts
- * with the OS scheduler when waiting for results from the GPU. Only one of
- * the scheduling flags can be set when creating a context.
- *
- * - ::CU_CTX_SCHED_SPIN: Instruct CUDA to actively spin when waiting for
- * results from the GPU. This can decrease latency when waiting for the GPU,
- * but may lower the performance of CPU threads if they are performing work in
- * parallel with the CUDA thread.
- *
- * - ::CU_CTX_SCHED_YIELD: Instruct CUDA to yield its thread when waiting for

- *
- * - ::CU_LIMIT_PRINTF_FIFO_SIZE controls the size in bytes of the FIFO used

- * must be performed before launching any kernel that uses the ::printf()

- * ::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.

- *
- * - ::CU_LIMIT_DEV_RUNTIME_PENDING_LAUNCH_COUNT controls the maximum number of

- * 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

- * 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

- * \brief Allocates memory that will be automatically managed by the Unified Memory system
- *
- * 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.

- * 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

- *
- * - ::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()

- * \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:

- * \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

-/**
- * \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,

- * - ::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.

- * 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,

- *
- * 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

- * ___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 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(),
- * ::cuParamSetf(),
- * ::cuParamSetv().
- *
- * Note that to use ::cuLaunchKernel(), the kernel \p f must either have
- * been compiled with toolchain version 3.2 or later so that it will

-/**
- * \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;
- unsigned int gridDimY;
- unsigned int gridDimZ;
- unsigned int blockDimX;
- unsigned int blockDimY;
- unsigned int blockDimZ;
- unsigned int sharedMemBytes;
- 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.
- *
- * When kernels are launched via ::cuLaunchCooperativeKernelMultiDevice(), the previous
- * block shape, shared size and parameter info associated with each ::CUDA_LAUNCH_PARAMS::function
- * in \p launchParamsList is overwritten.
- *
- * Note that to use ::cuLaunchCooperativeKernelMultiDevice(), the kernels must either have
- * been compiled with toolchain version 3.2 or later so that it will
- * contain kernel parameter information, or have no kernel parameters.
- * If either of these conditions is not met, then ::cuLaunchCooperativeKernelMultiDevice() will
- * return ::CUDA_ERROR_INVALID_IMAGE.

-/**
- * \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>
- * </ul>
- *
- * Note that, in contrast to ::cuStreamAddCallback, the function will not be
- * called in the event of an error in the CUDA context.
- *

- * \brief Creates a kernel execution node and adds it to a graph
- *
- * Creates a new kernel execution node and adds it to \p hGraph with \p numDependencies
- * dependencies specified via \p dependencies and arguments specified in \p nodeParams.
- * 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.

- CU_TR_ADDRESS_MODE_WRAP = 0,
- CU_TR_ADDRESS_MODE_CLAMP = 1,
- CU_TR_ADDRESS_MODE_MIRROR = 2,
- CU_TR_ADDRESS_MODE_BORDER = 3
- } CUaddress_mode;
- * \endcode
- * This is ignored if ::CUDA_RESOURCE_DESC::resType is ::CU_RESOURCE_TYPE_LINEAR. Also, if the flag, ::CU_TRSF_NORMALIZED_COORDINATES
- * is not set, the only supported address mode is ::CU_TR_ADDRESS_MODE_CLAMP.
- *
- * - ::CUDA_TEXTURE_DESC::filterMode specifies the filtering mode to be used when fetching from the texture. CUfilter_mode is defined as:
- * \code
- typedef enum CUfilter_mode_enum {
- CU_TR_FILTER_MODE_POINT = 0,
- CU_TR_FILTER_MODE_LINEAR = 1
- } CUfilter_mode;
- * \endcode
- * This is ignored if ::CUDA_RESOURCE_DESC::resType is ::CU_RESOURCE_TYPE_LINEAR.
- *
- * - ::CUDA_TEXTURE_DESC::flags can be any combination of the following:
- * - ::CU_TRSF_READ_AS_INTEGER, which suppresses the default behavior of
- * having the texture promote integer data to floating point data in the
- * range [0, 1]. Note that texture with 32-bit integer format would not be
- * promoted, regardless of whether or not this flag is specified.
- * - ::CU_TRSF_NORMALIZED_COORDINATES, which suppresses the default behavior
- * of having the texture coordinates range from [0, Dim) where Dim is the
- * width or height of the CUDA array. Instead, the texture coordinates
- * [0, 1.0) reference the entire breadth of the array dimension; Note that
- * 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,
