There are changes on MPI libraries on Pitzer after May 20. We will upgrade MOFED from 4.9 to 5.6 and recompile all OpenMPI and Mvapich2 against the newer MOFED version. Users with their own MPI libraries may see job failures and will need to rebuild their applications linked against the MPI libraries.
The default CPU binding for ORCA jobs can fail sporadically. The failure is almost immediate and produces a cryptic error message, e.g.:
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
