A threading code with MPI where MPI_Init_thread uses MPI_THREAD_MULTIPLE will fail because UCX from HPCX package is built without enabling multi-threading. UCX is the default framework for OMPI 4.0 and above.
Affects versions
Owens: openmpi/4.0.3-hpcx, openmpi/4.1.2-hpcx, penmpi/4.1.4-hpcx
Ascend: openmpi/4.1.3
There are currently issues with the Frame Renderer (Maya) interacitve app in ondemand.osc.edu
OSC staff are working with the vendor to resolve the issue
Please contact oschelp@osc.edu if there are questions.

OSC's starccm software license will expire at 12 a.m., Sunday, Feb 21, 2021, making the software unavailable until the license is renewed.
A partial-node MPI job may fail to start using mpiexec from intelmpi/2019.3 and intelmpi/2019.7 with error messages like
Users would encounter a MPI job failed with openmpi/3.1.0-hpcx on Owens and Pitzer. The job would stop with the error like "There are not enough slots available in the system to satisfy the slots". Please switch to openmpi/3.1.4-hpcx. The buggy version openmpi/3.1.0-hpcx will be removed on August 18 2020.
==========
Resolved: We removed openmpi/3.1.0-hpcx on August 18 2020.
