Hi Forum,
Bcoz I have difficulties to insert "-parallel" option to my supercomputer (They did not let me execute mpirun command directly), so I am trying the possible solution like this: Suppose I have a 4-cores Intel CPU personal computer, Can I execute the mpirun command without "-parallel" option (without decomposePar first), like this: mpirun -np 4 `which icoFoam` -case $FOAM_RUN/tutorials/icoFoam/cylinder > log & Is this meaningful? Please help.. Thank you.

Hi,
this means you run your case as a single case 4 times on 4 CPUs. I think that's not what you want to do. Kerstin |

Okay, how then can I achieve this goal??
I am using a super computer managed by lsf system, instead execute Code:
mpirun -np 4 icoFoam -parallel > log &; Code:
bsub ./c.lsf Code:
APP_NAME=snode NP=16 RUN="`which icoFoam` -case /home/users/temp/OpenFOAM/temp-1.5/run/tutorials/icoFoam/cylinder -parallel > log" Code:
attempt to run parallel on 1 processor.....FOAM aborting... What can I do? Please The question is now "How to use lsf system to manage the foam Job"

I know in Fluent, there's option "-lsf" and "-mpi=", eg.
bsub -I fluent 3d -lsf but OpenFOAM, only gives a "-parallel" option, is is possible to provide such more convenient option?
