Sparse-checkout from NVIDIA/cccl main branch to complete cccl_upstream: Added: - python/cuda_cccl/ (226 files) — Python bindings for device-level algorithms Critical for muh toolchain: cuda.compute.reduce_into, scan, radix_sort, etc. Includes 204 .py files with full test coverage for all 27 algorithms - ci/ (163 files) — Build/test infrastructure build_cub.sh, test_cub.sh, build_and_test_targets.sh, matrix.yaml Directly maps to our [INFRA-CI] and [INFRA-BUILD] items - .agent/skills/ (7 files) — NVIDIA's own agent skills for CCCL cccl-style/SKILL.md, cccl-test/SKILL.md, sass-diff/SKILL.md - docs/ (491 files) — Official CCCL documentation CI references, CMake guides, Python compute docs, libcudacxx PTX docs - test/ (12 files) — Top-level integration tests (cuda_smoke, stdpar) - Root configs: .clang-format, .clang-tidy, CONTRIBUTING.md, pyproject.toml - CLAUDE.md symlink → AGENTS.md (NVIDIA's standard) cccl_upstream now mirrors full NVIDIA/cccl structure: Before: 42M (cub + thrust + libcudacxx + cudax + c + examples + benchmarks) After: 53M (+python +ci +docs +.agent +test +configs) This completes the CCCL base needed for: - [muh-bench] items: ci/util/build_and_test_targets.sh for targeted builds - [CCCL-verify] items: python/cuda_cccl/tests/ as reference implementations - [CCCL-test] items: ci/test_cub.sh, ci/test_thrust.sh - Agent workflow: .agent/skills/ for consistent style and test patterns

CUB block-level algorithms are specialized for execution by threads in the same CUDA thread block:
|
|
|
|
* :cpp:class:`cub::BlockAdjacentDifference` computes the difference between adjacent items partitioned across a CUDA thread block
|
|
* :cpp:class:`cub::BlockDiscontinuity` flags discontinuities within an ordered set of items partitioned across a CUDA thread block
|
|
* :cpp:struct:`cub::BlockExchange` rearranges data partitioned across a CUDA thread block
|
|
* :cpp:class:`cub::BlockHistogram` constructs block-wide histograms from data samples partitioned across a CUDA thread block
|
|
* :cpp:class:`cub::BlockLoad` loads a linear segment of items from memory into a CUDA thread block
|
|
* :cpp:class:`cub::BlockMergeSort` sorts items partitioned across a CUDA thread block
|
|
* :cpp:class:`cub::BlockRadixSort` sorts items partitioned across a CUDA thread block using radix sorting method
|
|
* :cpp:struct:`cub::BlockReduce` computes reduction of items partitioned across a CUDA thread block
|
|
* :cpp:class:`cub::BlockRunLengthDecode` decodes a run-length encoded sequence partitioned across a CUDA thread block
|
|
* :cpp:struct:`cub::BlockScan` computes a prefix scan of items partitioned across a CUDA thread block
|
|
* :cpp:struct:`cub::BlockShuffle` shifts items partitioned across a CUDA thread block
|
|
* :cpp:class:`cub::BlockStore` stores items partitioned across a CUDA thread block to a linear segment of memory
