About
-----

Unified Communication X, or `UCX`_ is an open-source, production-grade communication framework for data-centric and high-performance applications.

.. note:: We use UCX in conjunction with the Open MPI installations available on Discoverer.

Supported versions
------------------

To check which UCX versions and build types are currently supported on Discoverer, execute on the login node:

.. code-block:: bash

 module avail ucx

The recipe followed to build the source code is available at:

https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/ucx

Loading/Compiler affinity
-------------------------

Currently, the only UCX build available is the one built using GCC compilers. That covers all practical cases UCX is involved into.

.. code-block:: bash

 module load ucx
