Detailed Description
determine the grid and block sizes to achieves maximum occupancy for a kernel
- Parameters
-
[out] gridSize minimum grid size for maximum potential occupancy [out] blockSize block size for maximum potential occupancy [in] f kernel function for which occupancy is calculated [in] dynSharedMemPerBlk dynamic shared memory usage (in bytes) intended for each block [in] blockSizeLimit the maximum block size for the kernel, use 0 for no limit
Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.
- Returns
hipSuccess,hipErrorInvalidValue
