Returns

Type	Description
System.Single	Time of execution in milliseconds (using GPU counter)

Declaration

public virtual void RunAsync(CUstream stream, params object[] parameters)

Parameters

Type	Name	Description
CUstream	stream	Stream
System.Object[]	parameters	Parameters as given by the kernel

RunCooperative(CUstream, Object[])

Launches a CUDA function where thread blocks can cooperate and synchronize as they execute

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.

The device on which this kernel is invoked must have a non-zero value for the device attribute::CU_DEVICE_ATTRIBUTE_COOPERATIVE_LAUNCH.

The total number of blocks launched 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.

The kernel cannot make use of CUDA dynamic parallelism.

Kernel parameters must 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.

Calling ::cuLaunchCooperativeKernel() sets persistent function state that is the same as function state set through ::cuLaunchKernel API

When the kernel \p f is launched via ::cuLaunchCooperativeKernel(), the previous block shape, shared size and parameter info associated with \p f is overwritten.

Note that to use ::cuLaunchCooperativeKernel(), the kernel \p f 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 ::cuLaunchCooperativeKernel() will return ::CUDA_ERROR_INVALID_IMAGE.

Declaration

public virtual void RunCooperative(CUstream stream, params object[] parameters)

Parameters

Type	Name	Description
CUstream	stream
System.Object[]	parameters

RunCooperativeKernelMultiDevie(CudaLaunchParams[], CudaCooperativeLaunchMultiDeviceFlags)

Launches CUDA functions on multiple devices where thread blocks can cooperate and synchronize as they execute

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.

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.

Declaration

public static void RunCooperativeKernelMultiDevie(CudaLaunchParams[] launchParameterList, CudaCooperativeLaunchMultiDeviceFlags flags)

Parameters

Type	Name	Description
CudaLaunchParams[]	launchParameterList	List of launch parameters, one per device
CudaCooperativeLaunchMultiDeviceFlags	flags	Flags to control launch behavior

SetCacheConfig(CUFuncCache)

On devices where the L1 cache and shared memory use the same hardware resources, this sets through config the preferred cache configuration for the device function hfunc. This is only a preference. The driver will use the requested configuration if possible, but it is free to choose a different configuration if required to execute hfunc.

This setting does nothing on devices where the size of the L1 cache and shared memory are fixed.

Switching between configuration modes may insert a device-side synchronization point for streamed kernel launches.

The supported cache modes are defined in CUFuncCache

Declaration

public void SetCacheConfig(CUFuncCache config)

Parameters

Type	Name	Description
CUFuncCache	config	Requested cache configuration

SetSharedMemConfig(CUsharedconfig)

Sets the shared memory configuration for a device function.

On devices with configurable shared memory banks, this function will force all subsequent launches of the specified device function to have the given shared memory bank size configuration. On any given launch of the function, the shared memory configuration of the device will be temporarily changed if needed to suit the function's preferred configuration. Changes in shared memory configuration between subsequent launches of functions, may introduce a device side synchronization point.

Any per-function setting of shared memory bank size set via cuFuncSetSharedMemConfig(CUfunction, CUsharedconfig) will override the context wide setting set with cuCtxSetSharedMemConfig(CUsharedconfig).

Changing the shared memory bank size will not increase shared memory usage or affect occupancy of kernels, but may have major effects on performance. Larger bank sizes will allow for greater potential bandwidth to shared memory, but will change what kinds of accesses to shared memory will result in bank conflicts.

This function will do nothing on devices with fixed shared memory bank size.

The supported bank configurations are

• DefaultBankSize: set bank width to the default initial setting (currently, four bytes).
• FourByteBankSize: set shared memory bank width to be natively four bytes.
• EightByteBankSize: set shared memory bank width to be natively eight bytes.

Declaration

public void SetSharedMemConfig(CUsharedconfig config)

Parameters

Type	Name	Description
CUsharedconfig	config	requested shared memory configuration
