CUresult cuLaunchGridAsync (CUfunction f, int grid_width, int grid_height, CUstream hStream)

Deprecated

Invokes the kernel f on a grid_width x grid_height grid of blocks. Each block contains the number of threads specified by a previous call to cuFuncSetBlockShape().

Parameters:

f - Kernel to launch
grid_width - Width of grid in blocks
grid_height - Height of grid in blocks
hStream - Stream identifier

Returns:

CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_LAUNCH_FAILED, CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES, CUDA_ERROR_LAUNCH_TIMEOUT, CUDA_ERROR_LAUNCH_INCOMPATIBLE_TEXTURING, CUDA_ERROR_SHARED_OBJECT_INIT_FAILED

Note:

In certain cases where cubins are created with no ABI (i.e., using ptxas --abi-compile no), this function may serialize kernel launches. In order to force the CUDA driver to retain asynchronous behavior, set the CU_CTX_LMEM_RESIZE_TO_MAX flag during context creation (see cuCtxCreate).

This function uses standard semantics.

Note that this function may also return error codes from previous, asynchronous launches.
