Dear all,
I get an error while running grompp or mdrun in a Sun cluster. Each node has 4
processors. I am submitting the job via a SGE script.
After, I submit the job by "$qsub test_gromacs", the run terminates with the
following message in the log file. Please tell me how to troubleshoot this
problem. The error is repeated if the -np option is changed from 4 to 8.

Fatal error: run input file topol.tpr was made for 4 nodes,
while mdrun expected it to be for 1 nodes.
