| Description: | UCX stands for Unified Communication X. UCX provides an optimized communication
layer for Message Passing (MPI), PGAS/OpenSHMEM libraries and RPC/data-centric
applications. UCX utilizes high-speed networks, such as RDMA (InfiniBand, RoCE,
etc), Cray Gemini or Aries, for inter-node communication. If no such network is
available, TCP is used instead. UCX supports efficient transfer of data in
either main memory (RAM) or GPU memory (through CUDA and ROCm libraries).
In addition, UCX provides efficient intra-node communication, by leveraging the
following shared memory mechanisms: posix, sysv, cma, knem, and xpmem. |
