Problem running on Cluster

Sway · July 29, 2015, 08:00

hey i hope someone can help me on this:

i tried setting up a little cluster, currently 2 Computers (8+4cpus).
openfoam 2.4 installed on the better computer.
i set up keyless ssh and nfs, there everything semse to be fine.

now the problem:
when starting openfoam it just stays idle, or freezes and does nothing.
no core on both machines starts working.
i use the start command

Code:

decomposePar

mpirun -n 12 renumberMesh -overwrite -parallel

pyFoamPlotRunner.py mpirun -hostfile /home/user/OpenFOAM/user-2.4.0/run/machines -np 12 pimpleFoam -parallel

any thoughts? thank you!!

I solved it, it was because of diffrent Versions of Openmpi.
