NVIDIA Collective Communication Library (NCCL) Runtime

The `nvidia-nccl-cu13` package provides the NVIDIA Collective Communication Library (NCCL) runtime specific to CUDA 13.x. NCCL is a library of standard routines for inter-GPU communication, optimized for NVIDIA GPUs. It is primarily used as a backend by deep learning frameworks like PyTorch and TensorFlow for distributed training on multi-GPU systems. This package does not expose a direct Python API for end-users but provides the necessary shared libraries. It's released in conjunction with NVIDIA CUDA Toolkit versions.
