CCCL (CUDA C++ Core Libraries) provides: - CUB: device/block/warp-level GPU primitives (reduce, scan, sort, topk) - Thrust: high-level parallel algorithms (transform_reduce, sort, scan) - libcudacxx: CUDA C++ standard library (atomics, barriers, memory) - cudax: experimental features (memory resources, allocators) - Tuning policies: per-SM hardware-specific algorithm parameters Competition optimization vectors mapped to CCCL: - Output TPS (83% weight): warp_reduce, block_reduce, device_topk - Input TPS (14% weight): device_scan, block_load, prefetch - Cache TPS (3% weight): prefix caching strategy patterns - Memory (0.9 util): pooled/cached/buddy allocators Source: https://github.com/NVIDIA/cccl (shallow clone, HEAD only) License: Apache-2.0

# CUDA CCCL Python Package
|
|
|
|
[`cuda.cccl`](https://nvidia.github.io/cccl/python)
|
|
provides a Pythonic interface to the
|
|
[CUDA Core Compute Libraries](https://nvidia.github.io/cccl/cpp.html#cccl-cpp-libraries).
|
|
It provides the following modules:
|
|
|
|
- **`cuda.compute`** - Device-level parallel algorithms (reduce, scan, sort, etc.) and iterators
|
|
- **`cuda.cccl.headers`** - Programmatic access to CCCL headers
|
|
|
|
## Installation
|
|
|
|
Install from PyPI:
|
|
|
|
```bash
|
|
pip install cuda-cccl[cu13] # For CUDA 13.x (pip-installed cuda-toolkit)
|
|
pip install cuda-cccl[cu12] # For CUDA 12.x (pip-installed cuda-toolkit)
|
|
```
|
|
|
|
If you already have a CUDA toolkit on your system and do not want pip to
|
|
install it, use the `sysctk` variants:
|
|
|
|
```bash
|
|
pip install cuda-cccl[sysctk13] # For CUDA 13.x (system CUDA toolkit)
|
|
pip install cuda-cccl[sysctk12] # For CUDA 12.x (system CUDA toolkit)
|
|
```
|
|
|
|
For a minimal install without Numba (useful when supplying pre-compiled operators):
|
|
|
|
```bash
|
|
pip install cuda-cccl[minimal-cu13] # pip-installed cuda-toolkit
|
|
pip install cuda-cccl[minimal-sysctk13] # system CUDA toolkit
|
|
```
|
|
|
|
Install from conda-forge:
|
|
|
|
```bash
|
|
conda install -c conda-forge cccl-python
|
|
```
|
|
|
|
**Requirements:** Python 3.10+, CUDA Toolkit 12.x or 13.x, NVIDIA GPU with Compute Capability 7.5+
