NCCL: Accelerated Collective Communications for GPUs
Abstract:
We present NCCL, a library of multi-GPU communication collectives (e.g., broadcast, all-reduce, all-gather). NCCL enables applications to harness the computational throughput of multiple GPUs with minimal developer effort by providing optimized, topology-aware, asynchronous collectives with a familiar API.
