Partial progress. The scientist that developed the model took a look at the output and found that instead of one model run being ran in parallel srun had ran multiple instances of the model, one per thread, which for this test was 110 threads.
This sounds like MVAPICH isn't built to support Slurm, from the Slurm MPI guide you need to build it with this to enable Slurm support (and of course add any other options you were using):
./configure --with-pmi=pmi2 --with-pm=slurm All the best, Chris -- Chris Samuel : http://www.csamuel.org/ : Berkeley, CA, USA
