NVIDIA Collective Communications Library (NCCL) provides high-performance multi-GPU and multi-node communication primitives optimized for NVIDIA GPUs and networks. It implements collectives such as all-reduce, all-gather, broadcast, reduce, reduce-scatter, and point-to-point sends and receives, designed for high bandwidth and low latency over PCIe, NVLink, and inter-node interconnects, with a single-kernel implementation for low-latency synchronization suitable for distributed training and real-time inference. NCCL features dynamic topology detection, a simple C-based API compatible with MPI-like programming, and easy installation via GitHub or the NVIDIA HPC SDK, along with tools like NCCL RAS and Inspector for debugging and performance tuning.
