NVIDIA Collective Communication Library (NCCL) Runtime for CUDA 12

nvidia-nccl-cu12 (version 2.29.7) is the Python package providing the NVIDIA Collective Communication Library (NCCL) runtime specifically built for CUDA 12.x. NCCL is a foundational library for high-performance inter-GPU and inter-node communication primitives, such as all-reduce, all-gather, broadcast, and point-to-point operations, crucial for accelerating distributed deep learning workloads. It features a rapid release cadence, often synchronized with CUDA toolkit and major deep learning framework updates.
