Detailed Description

class cub::BlockRadixRank< BLOCK_DIM_X, RADIX_BITS, IS_DESCENDING, MEMOIZE_OUTER_SCAN, INNER_SCAN_ALGORITHM, SMEM_CONFIG, BLOCK_DIM_Y, BLOCK_DIM_Z, PTX_ARCH >

BlockRadixRank provides operations for ranking unsigned integer types within a CUDA thread block.

Template Parameters
BLOCK_DIM_XThe thread block length in threads along the X dimension
RADIX_BITSThe number of radix bits per digit place
IS_DESCENDINGWhether or not the sorted-order is high-to-low
MEMOIZE_OUTER_SCAN[optional] Whether or not to buffer outer raking scan partials to incur fewer shared memory reads at the expense of higher register pressure (default: true for architectures SM35 and newer, false otherwise). See BlockScanAlgorithm::BLOCK_SCAN_RAKING_MEMOIZE for more details.
INNER_SCAN_ALGORITHM[optional] The cub::BlockScanAlgorithm algorithm to use (default: cub::BLOCK_SCAN_WARP_SCANS)
SMEM_CONFIG[optional] Shared memory bank mode (default: cudaSharedMemBankSizeFourByte)
BLOCK_DIM_Y[optional] The thread block length in threads along the Y dimension (default: 1)
BLOCK_DIM_Z[optional] The thread block length in threads along the Z dimension (default: 1)
PTX_ARCH[optional] \ptxversion
