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

Ranges Library

=======================
|
|
|
|
See the documentation of the standard headers `\<iterator\> <https://en.cppreference.com/w/cpp/header/iterator>`_ and

`\<ranges\> <https://en.cppreference.com/w/cpp/header/ranges>`_

|
|
* - `\<cuda/std/ranges\> <https://en.cppreference.com/w/cpp/header/ranges>`_

|
Extensions
|
|
----------
|
|
|
|
- All library features are available from C++17 onwards. The concepts can be used like type traits prior to C++20.

|
Restrictions
|
|
------------
|
|
|
|
- Subsumption does not work prior to C++20
|
|
- Subsumption is only partially implemented in the compiler until nvcc 12.4
|
|
|
|
Omissions
|
|
---------
|
|
|
|
- Range based algorithms have *not* been implemented
|
|
- Views have *not* been implemented
