[Mvapich-discuss] Enable verbose logging

[Panda, Dhabaleswar]

Thanks for your note. Sorry to know that you are experiencing this issue. Can you please update the MVAPICH version to the latest one (2.3.6) and see whether the issue persists? The 2.3.4 version is already more than one and a half years old.

Thanks,

DK

Greetings, MVAPICH team,

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?

Thank you very much in advance.

Best regards,
