UCX stands for Unified Communication X. It requires either RDMA-capable device
(InfiniBand, RoCE, etc), Cray Gemini or Aries, for inter-node communication.
Future versions will support also TCP for inter-node, to lift that hardware
In addition, the library can be used for intra-node communication by leveraging
the following shared memory mechanisms: posix. sysv, cma, knem, xpmem.
