[gmx-users] Problem in mdrun_mpi using MPICH

[Alok]

Hello Dr. Eric & Dr. David,

Thanks for your reply. I have set the path for MPICH compilers and then
compiled for MPICH parallel environment. Now I am not getting that warning
related to "lamboot". Still I am not able to run the script. I am getting
following error message when tried tu run mdrun_mpi
______________________________________________________________
Warning: no access to tty (Bad file descriptor).
Thus no job control in this shell.
Got 2 slots.
Unrecognized argument mdrun_mpi ignored.        "

_________________________________________________________________

So I am not sure that it is compiled for MPICH or not. Is there a way by
which we may know for what it is compiled of is there a problem in my
script ?


I was using following script and command

---------------------------------------------------------------------------

#!/bin/csh -f
#
#
# (c) 2004 Sun Microsystems, Inc. Use is subject to license terms.

# ---------------------------
# our name
#$ -N MPI_Job
#
# pe request
#$ -pe mpich* 2-20
#
# MPIR_HOME from submitting environment
#$ -v MPIR_HOME=/opt/mpichdefault-1.2.6
# ---------------------------

#
# needs in
#   $NSLOTS
#       the number of tasks to be used
#   $TMPDIR/machines
#       a valid machine file to be passed to mpirun

echo "Got $NSLOTS slots."

# enables $TMPDIR/rsh to catch rsh calls if available
set path=($TMPDIR $path)

$MPIR_HOME/bin/mpirun -np $NSLOTS -machinefile $TMPDIR/machines -nolocal *

---------------------------------------------------------------------------


and start the job by using following command.
qsub -pe mpichpar <no of nodes> -q par.q <script_name>

where * is Path of the input file including parallel program name (in my
case it is /users/alokjain/mdrun_mpi -s full.tpr -o full -x full -c
after_full -e full -g full)

Best regards,
Alok Jain
