I am trying to compile NAMD and run it on MPICH on Mac OSX. Finally I
compile NAMD2.5 and MPICH1.2.6 by using IBM XLC compiler. However I
encounter following problem when run it. Could anyone give me some hints?
The only message is from the log file.
"Could not find enough machines for architecture freebsd_ppc"
My script file is as follows.
### Begin embedded Grid Engine arguments
# (name the job)
set NAMD_SCRIPT = $1
#$ -N sstz2.6mx
# (ask for our newly created PE and a range of 3-5 CPUs)
#$ -hard -pe mpich 2
# (assume current working directory for paths)
# (set group variable)
#$ -v MPICH_PROCESS_GROUP=no
### End embedded Grid Engine commmands
echo "I have $NSLOTS slots to run on!"
/Users/j0l6571/bin/mpich-1.2.6/bin/mpirun -np $NSLOTS -machinefile
$NAMD_SCRIPT > results.log
And I also try to use the following command.
/Users/l0l6571/bin/mpich-1.2.6/bin/mpirun -np $NSLOTS -machinefile
But the above command give me such error.
