Whenever it tries to submit a job, it repeatedly gives these errors

Please configure as appropriate and try again.

[amr-090:3572858] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!

The application appears to have been direct launched using “srun”,
but OMPI was not built with SLURM’s PMI support and therefore cannot
execute. There are several options for building PMI support under
SLURM, depending upon the SLURM version you are using:

version 16.05 or later: you can use SLURM’s PMIx support. This
requires that you configure and build SLURM –with-pmix.

Versions earlier than 16.05: you must use either SLURM’s PMI-1 or
PMI-2 support. SLURM builds PMI-1 by default, or you can manually
install PMI-2. You must then build Open MPI using –with-pmi pointing
to the SLURM PMI library location.`

This problem has been occurring ever since they updated the OS to Ubuntu.
