Dear Vishal Gupta,

Isn't it obvious: The namelist '&ions' is indeed not present in your input; this is required, even if being empty, when doing "calculation = 'relax'".

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
