Job sent on OpenPBS hangs in R status

I am still confused about the passwordless thing. I am using openPBS on a single machine. I am not using external nodes or servers. I am connecting to the machine with SSH and password, but then I am sending the job using openPBS on the machine from the machine itself.

• mpi uses either rsh or ssh as launchers , if your MPI is compiled with openpbs TM libraries, then PBS would take care of the internode communication .

Maybe I am missing something but I do not need to do ssh on the server or different nodes. I only use SSH to access the workstation remotely.

Please check this link c - MPI programs hanging up - Stack Overflow

Regarding the second point, I am able to run mpirun with all the available cores (20) without problems.

Please share the batch script and env variables used .
