Hi Diego,

I don't know about MPICH, but in case you haven't done this already, you 
might check the Slurm side if everything is ready:

Did you make sure your Slurm was built with PMI support (as in 
`configure ... --with-pmix=/path/to/pmix`)?

Do you see MPI types:
srun --mpi=list

Does a test like the following work:
srun --mpi=pmix -n2 -N2 pmix_client -n 2 --job-fence -c
