Comment (by Roland Haas):

The first issue with this script would be that on the two clusters (Stampede2 and Comet) you are not supposed to use mpirun but instead their own ibrun tool. So there’s one difference.

This tool then potentially (who knows it’s a black box) looks what --tasks-per-node is set to do do … something.

Basically: the docs say to do “A”, then you have to do “A” and not “B” which you would do on the cluster you are testing this on.
