Hi Shubhra,

>From your mdout file:

| Running AMBER/MPI version on 20 nodes

| WARNING: The number of processors is not a power of 2
| this may be inefficient on some systems.

Try running a shorter version of the job with fewer processors (start
at 2 or 4 and increase accordingly) and see if that fixes the issue.
It's highly likely there are parts of the parallel code that aren't
tested for a number of processors that are not a power of 2.
