NVIDIA Optimized primitives for inter-GPU communication
NCCL (pronounced "Nickel") is a stand-alone library of standard communication
routines for GPUs, implementing all-reduce, all-gather, reduce, broadcast,
reduce-scatter, as well as any send/receive based communication pattern. It
has been optimized to achieve high bandwidth on platforms using PCIe, NVLink,
NVswitch, as well as networking using InfiniBand Verbs or TCP/IP sockets. NCCL
supports an arbitrary number of GPUs installed in a single node or across
multiple nodes, and can be used in either single- or multi-process (e.g., MPI)
applications.
