# nvidia-nccl-cu13 — NVIDIA Collective Communication Library (NCCL) Runtime

License: unclear · Maintenance: active · Popularity: top 1,000 on PyPI

## Install

pip install nvidia-nccl-cu13
uv add nvidia-nccl-cu13
poetry add nvidia-nccl-cu13

## Description

NCCL (pronounced "Nickel") is a stand-alone library of standard collective communication routines for GPUs, implementing all-reduce, all-gather, reduce, broadcast, and reduce-scatter. It has been optimized to achieve high bandwidth on any platform using PCIe, NVLink, NVswitch, as well as networking using InfiniBand Verbs or TCP/IP sockets.

## AI interpretation — verify before relying

NCCL provides GPU collective communication primitives (all-reduce, all-gather, reduce, broadcast, reduce-scatter) optimized for high-bandwidth transfers across PCIe, NVLink, NVswitch, InfiniBand, and TCP/IP.

Verdict: nvidia-nccl-cu13 is an actively maintained library for GPU collective communication in distributed training, with no known vulnerabilities and broad Python version support. However, unclear licensing and platform-specific installation requirements demand careful evaluation before production use.
