fws_md.tpr -o fws_md.trr -c fws_pmd.pdb -g md.log -e md.edr
*for mpirun 3 nodes i got the output,*
while trying to increase the nodes to 5 or 8 i am getting the following

mpirun -np 5 -machinefile machinefile /usr/local/gromacs/bin/mdrun_mpi -s
fws_md.tpr -o fws_md.trr -c fws_pmd.pdb -g md.log -e md.edr
