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

Architecture flags
|
|
==================
|
|
|
|
CCCL builds device code for the SM architectures named in ``CMAKE_CUDA_ARCHITECTURES``, a
|
|
semicolon-separated list of SM numbers, each optionally tagged ``-real`` (embed SASS) or
|
|
``-virtual`` (embed PTX for JIT on newer GPUs). CMake also accepts ``native``, ``all``, and
|
|
``all-major``. The
|
|
`CUDA_ARCHITECTURES property <https://cmake.org/cmake/help/latest/prop_tgt/CUDA_ARCHITECTURES.html>`_
|
|
documents the standard syntax and values.
|
|
|
|
CCCL adds two values, expanded at configure time by ``cccl_check_cuda_architectures()`` against
|
|
the toolkit found at configure time:
|
|
|
|
- ``all-cccl`` — every architecture the current nvcc supports at or above CCCL's minimum.
|
|
- ``all-major-cccl`` — one entry per major architecture at or above the minimum, carrying
|
|
forward PTX on the highest.
|
|
|
|
Both resolve against the installed toolkit rather than a fixed table. The minimum supported
|
|
architecture and the full expansion logic live in ``cmake/CCCLCheckCudaArchitectures.cmake``.
|
|
Expansion runs only for a top-level CCCL build; downstream consumers pass a concrete list or
|
|
``native``.
