 %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.

 libucm is a standalone non-unloadable library which installs hooks
-for virtual memory changes in the current process. Then, it calls
-user-defined callbacks, which may potentially override the default
-behavior, or just passively listen and update their own data. libucm
-does not use libuct, to avoid making it non-unloadable as well, and
-impelements a basic logging service which is safe to use from malloc
-hooks.
