Dear Rayson,

That is a Nuemrical model that is written by National weather service of a
country. The logs of the model show every detail about the simulation
progress. I have checked on the remote nodes as well the application binary
is running but the logs show no progress, it is just waiting at a point.
The input data is correct everything is fine. How can I check if the MPI
task is waiting for a message?
