 * 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.
 * Note that the CUDA driver will set the \p limit to the maximum of \p value
 * and what the kernel function requires.
 *
 * - ::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

 * \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.
 * - On ARM, managed memory is not available on discrete gpu with Drive PX-2.

 * \brief Registers an existing host memory range for use by CUDA

 * 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

 * best used sparingly to register staging areas for data exchange between
 * host and device.
 *
 * This function has limited support on Mac OS X. OS 10.7 or higher is required.
 *
 * 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.
 *
 * All of these flags are orthogonal to one another: a developer may page-lock
 * memory that is portable or mapped with no restrictions.
 *
 * The CUDA context must have been created with the ::CU_CTX_MAP_HOST flag in
 * order for the ::CU_MEMHOSTREGISTER_DEVICEMAP flag to have any effect.
 *
 * 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

 * but it will be suitable for use on all devices provided Unified Virtual Addressing

    } CUDA_ARRAY3D_DESCRIPTOR;
 * \endcode
 * where:
 *
 * - \p Width, \p Height, and \p Depth are the width, height, and depth of the
 * 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

 * - \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,

/**
 * \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

 * Prefetches memory to the specified destination device.  \p devPtr is the

 * 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

 * 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.

/**
 * \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,

 * if either all the pages don't have the same preferred location or some of the pages don't have a

 * will be a list of device ids that had ::CU_MEM_ADVISE_SET_ACCESSED_BY set for that entire memory range.

 * (i.e. \p data has 3 elements) and only device 0 has the advice set, then the result returned will be

 * - ::CU_MEM_RANGE_ATTRIBUTE_LAST_PREFETCH_LOCATION: If this attribute is specified, \p data will be

 * 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

 * 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_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() sets persistent function state that is
 * the same as function state set through the following deprecated APIs:
 *  ::cuFuncSetBlockShape(),
 *  ::cuFuncSetSharedSize(),
 *  ::cuParamSetSize(),
 *  ::cuParamSeti(),

 * - ::CUDA_LAUNCH_PARAMS::gridDimY is the height of the grid in blocks. This must match across

 * - ::CUDA_LAUNCH_PARAMS::gridDimZ is the depth of the grid in blocks. This must match across

 * - ::CUDA_LAUNCH_PARAMS::blockDimZ is the Z dimension of each thread block. This must match across

 * - ::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

 *   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

/**
 * \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.

 *
 * \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 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;

 *   - ::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.
 *
 * - ::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.
