We are running an application with MVAPICH 2.3.4 on multiple nodes (e.g. 16) and occasionally the application will get stuck with what appears to be communication issues between MPI processes. Is there a way to turn on verbose logging when using mpirun_rsh
or the Slurm srun to launch the MPI processes, to help us troubleshoot our MPI communication issues on the IB network?</div>
