Hi Tim,

We dive into Slurm starting with 20.11.0 and IntelMPI.
We faced pinning issues with mpirun that did not exist when using directly srun.

Then we hit the wall with the 20.11.1 and the PMI issue.

It led us to try the 20.02.6 which solved both the PMI issue and the pinning issue with mpirun.

Do you think the revert announced with 20.11.3 could also solved our pinning issue ?
