Hi All,
Ok, I've successfully created the mpi version of mdrun. Am now trying to
run my simulation on 32 processors. After processing with grompp and the
option -np 32, I use mdrun with the following script (where CONF is the
input file, NPROC is the number of processors):
/opt/mpich/intel/bin/mpirun -v -np $NPROC -machinefile \$TMPDIR/machines
~/gromacs-mpi/bin/mdrun -np $NPROC -s $CONF -o $CONF -c After$CONF -e
$CONF -g $CONF >& $CONF.job
Everything seems to start up ok, but then GMX stalls (it never actually
starts the simulation. It stalls for about 7 minutes then completely
aborts). I've pasted the log file below, which shows that the
simulation stalls at Step 0, but there's no discernible error (only
claims that AMD 3D Now support is not available, which makes sense b/c
I'm not running on AMD).
If you scroll further down, I've also pasted the job file, FullMD7.job,
which is normally empty if everything is running smoothly. There seems
to be some errors at the end, but they're rather cryptic to me, nor am I
sure if this is a cause or effect. If anyone has any suggestions, I'd
love to hear them.
Thanks,
Arneh
