Hi, 

My mpiexec command fails to launch any processes.   I ran it with the -verbose option but didn’t see any obvious errors in the output (attached).

The command is:

mpiexec -launcher ssh -verbose -print-all-exitcodes -wdir  <directory> -np 20 -ppn 1  <more args…>

I am running MPICH 4.0.1 under Slurm 20.11.8.  Thanks for any help.

Kurt
