Detailed Description

Default policy that provides the standard GPU mapping: gang(dim:1) -> BlockX (gridDim.x / blockIdx.x) gang(dim:2) -> BlockY (gridDim.y / blockIdx.y) gang(dim:3) -> BlockZ (gridDim.z / blockIdx.z) worker -> ThreadY (blockDim.y / threadIdx.y) vector -> ThreadX (blockDim.x / threadIdx.x) seq -> Sequential.
