◆ BlockHistogramAlgorithm

BlockHistogramAlgorithm enumerates alternative algorithms for the parallel construction of block-wide histograms.

Enumerator
BLOCK_HISTO_SORT 
Overview
Sorting followed by differentiation. Execution is comprised of two phases:
  1. Sort the data using efficient radix sort
  2. Look for "runs" of same-valued keys by detecting discontinuities; the run-lengths are histogram bin counts.
Performance Considerations
Delivers consistent throughput regardless of sample bin distribution.
BLOCK_HISTO_ATOMIC 
Overview
Use atomic addition to update byte counts directly
Performance Considerations
Performance is strongly tied to the hardware implementation of atomic addition, and may be significantly degraded for non uniformly-random input distributions where many concurrent updates are likely to be made to the same bin counter.

Enumerator
BLOCK_REDUCE_RAKING_COMMUTATIVE_ONLY 
Overview
An efficient "raking" reduction algorithm that only supports commutative reduction operators (true for most operations, e.g., addition).
Execution is comprised of three phases:
  1. Upsweep sequential reduction in registers (if threads contribute more than one input each). Threads in warps other than the first warp place their partial reductions into shared memory.
  2. Upsweep sequential reduction in shared memory. Threads within the first warp continue to accumulate by raking across segments of shared partial reductions
  3. A warp-synchronous Kogge-Stone style reduction within the raking warp.
BLOCK_REDUCE_RAKING data flow for a hypothetical 16-thread thread block and 4-thread raking warp.
Performance Considerations
  • This variant performs less communication than BLOCK_REDUCE_RAKING_NON_COMMUTATIVE and is preferable when the reduction operator is commutative. This variant applies fewer reduction operators than BLOCK_REDUCE_WARP_REDUCTIONS, and can provide higher overall throughput across the GPU when suitably occupied. However, turn-around latency may be higher than to BLOCK_REDUCE_WARP_REDUCTIONS and thus less-desirable when the GPU is under-occupied.
BLOCK_REDUCE_RAKING 
Overview
An efficient "raking" reduction algorithm that supports commutative (e.g., addition) and non-commutative (e.g., string concatenation) reduction operators. \blocked.
Execution is comprised of three phases:
  1. Upsweep sequential reduction in registers (if threads contribute more than one input each). Each thread then places the partial reduction of its item(s) into shared memory.
  2. Upsweep sequential reduction in shared memory. Threads within a single warp rake across segments of shared partial reductions.
  3. A warp-synchronous Kogge-Stone style reduction within the raking warp.
BLOCK_REDUCE_RAKING data flow for a hypothetical 16-thread thread block and 4-thread raking warp.
Performance Considerations
  • This variant performs more communication than BLOCK_REDUCE_RAKING and is only preferable when the reduction operator is non-commutative. This variant applies fewer reduction operators than BLOCK_REDUCE_WARP_REDUCTIONS, and can provide higher overall throughput across the GPU when suitably occupied. However, turn-around latency may be higher than to BLOCK_REDUCE_WARP_REDUCTIONS and thus less-desirable when the GPU is under-occupied.
BLOCK_REDUCE_WARP_REDUCTIONS 
Overview
A quick "tiled warp-reductions" reduction algorithm that supports commutative (e.g., addition) and non-commutative (e.g., string concatenation) reduction operators.
Execution is comprised of four phases:
  1. Upsweep sequential reduction in registers (if threads contribute more than one input each). Each thread then places the partial reduction of its item(s) into shared memory.
  2. Compute a shallow, but inefficient warp-synchronous Kogge-Stone style reduction within each warp.
  3. A propagation phase where the warp reduction outputs in each warp are updated with the aggregate from each preceding warp.
BLOCK_REDUCE_WARP_REDUCTIONS data flow for a hypothetical 16-thread thread block and 4-thread raking warp.
Performance Considerations
  • This variant applies more reduction operators than BLOCK_REDUCE_RAKING or BLOCK_REDUCE_RAKING_NON_COMMUTATIVE, which may result in lower overall throughput across the GPU. However turn-around latency may be lower and thus useful when the GPU is under-occupied.

◆ BlockScanAlgorithm

BlockScanAlgorithm enumerates alternative algorithms for cub::BlockScan to compute a parallel prefix scan across a CUDA thread block.

Enumerator
BLOCK_SCAN_RAKING 
Overview
An efficient "raking reduce-then-scan" prefix scan algorithm. Execution is comprised of five phases:
  1. Upsweep sequential reduction in registers (if threads contribute more than one input each). Each thread then places the partial reduction of its item(s) into shared memory.
  2. Upsweep sequential reduction in shared memory. Threads within a single warp rake across segments of shared partial reductions.
  3. A warp-synchronous Kogge-Stone style exclusive scan within the raking warp.
  4. Downsweep sequential exclusive scan in shared memory. Threads within a single warp rake across segments of shared partial reductions, seeded with the warp-scan output.
  5. Downsweep sequential scan in registers (if threads contribute more than one input), seeded with the raking scan output.
BLOCK_SCAN_RAKING data flow for a hypothetical 16-thread thread block and 4-thread raking warp.
Performance Considerations
  • Although this variant may suffer longer turnaround latencies when the GPU is under-occupied, it can often provide higher overall throughput across the GPU when suitably occupied.
BLOCK_SCAN_RAKING_MEMOIZE 
Overview
Similar to cub::BLOCK_SCAN_RAKING, but with fewer shared memory reads at the expense of higher register pressure. Raking threads preserve their "upsweep" segment of values in registers while performing warp-synchronous scan, allowing the "downsweep" not to re-read them from shared memory.
BLOCK_SCAN_WARP_SCANS 
Overview
A quick "tiled warpscans" prefix scan algorithm. Execution is comprised of four phases:
  1. Upsweep sequential reduction in registers (if threads contribute more than one input each). Each thread then places the partial reduction of its item(s) into shared memory.
  2. Compute a shallow, but inefficient warp-synchronous Kogge-Stone style scan within each warp.
  3. A propagation phase where the warp scan outputs in each warp are updated with the aggregate from each preceding warp.
  4. Downsweep sequential scan in registers (if threads contribute more than one input), seeded with the raking scan output.
BLOCK_SCAN_WARP_SCANS data flow for a hypothetical 16-thread thread block and 4-thread raking warp.
Performance Considerations
  • Although this variant may suffer lower overall throughput across the GPU because due to a heavy reliance on inefficient warpscans, it can often provide lower turnaround latencies when the GPU is under-occupied.
