Running fluent parallel with PBS

August 5, 2007, 12:03

Hi,

I am trying to configure fluent to run on my new cluster with a TORQUE/PBS scheduler. I can run serial jobs but when i try to run parallel jobs I get mpid errors.

Here is the PBS script I am using

fluent 3d -g -pnmpi -t$NPROCS -cnf=$PBS_NODEFILE

Here is the error I get Starting /opt/Fluent.Inc/fluent6.3.26/multiport/mpi/lnamd64/hp/bin/mpirun -TCP -f /tmp/fluent-appfile.6034 mpid: Cannot create shared memory segment of 1073766400 bytes

Any help regarding this is very appreciated. Thanks
