OpenFOAM Cluster Installation

Saxwax · November 14, 2011, 22:02

Hi All,

I'm setting up a small (<30 nodes) cluster at the moment using several PCs and a Gb Ethernet switch. I almost (I hope) have the thing working but am unsure about one thing.

I have compiled and set up OpenFOAM 2.0.x on the head node under /opt/OpenFOAM. I have shared /home across all nodes using NFS and enabled passwordless SSH. What I would like to know is whether I need /opt/OpenFOAM to be shared via NFS also or is it sufficient to have the installation only accessed by the head node. I'm a bit unsure about how OpenFOAM/openMPI does things.

Cheers,

D.

Dear Sawmax,

Did you solve your problem? Because I have the same doubt and I don't know what to do.

Regards,

eshraghi,

I have installed Openfoam in a Beowulf Cluster using SSH. You must install it in the master node and share with the slave nodes. Let me know you have any question.
