OTHER MPI ERROR while execution

[pankaj_srivastava1]

We have a two node cluster in our lab and it is running on Centos 7.9 version. I have installed intel oneapi basic +hpc cluster edition. I have successfully compiled the VASP code also. However, I can't run any calculations. It is showing 'OTHER MPI ERROR' message. Any suggestion or clue regarding the issue would be greatly appreciated.

#My command and error message:
user@system: mpirun -np 4 ~/PATH_TO_VASP_FOLDER/bin/vasp_std

This seems to be a problem with your MPI installation or configuration and not with VASP.
Have you tried running on a single node? Does it work then?
