UCX Version Mismatch Alarm

Symptom

The following error is reported during execution:

UCX WARN UCP version is incompatible, required:x.xx, actual:x.xx

Possible Cause

The XUCG and Hyper MPI are built on UCX of a certain version, but the alarm indicates that a different UCX version is being used at runtime. This is typically caused by a pre-existing UCX in the system directory. Without importing the correct UCX environment variables prior to building XUCG, XUCG depends on the incorrect UCX version.

Recovery Procedure

Build Hyper MPI by strictly following the user guide and set the UCX environment variables correctly before building the XUCG.
