[pandey at bioinfo.ernet.in]

Hi group,
I have started working on gromcas quite recently.
I am using parallel processing with MPI.
But, when i submit task for grompp and mdrun, the grompp get execute
sucessfully, error comes in mdrun_mpi execution.It gets terminated
abnormally.

I have test the input file for correctness on single processor, it runs
sucessfully.

Below is the part of error message
