ucx

UCX is an optimized communication framework for high-performance distributed 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. The acronym UCX stands for "Unified Communication X".
