start comsol server on cluster on multiple compute nodes

Dear,

I would like to run the comsol server on multiple nodes, with each 8 cores, on a linux cluster. For this I use the following command in a PBS script:

comsol -nn 1 -np 8 -f ${PBS_NODEFILE} server > comsollog &

This seems to open a comsol server on 2 nodes, but they don't do what I expect: solve the problem faster than on one node. On both nodes, the full capacity of the compute node is not used, while the full capacity is used when I run it on one node.

If anyone has experience with running comsol on a linux cluster with the matlab livelink (or any livelink), I would happy if I could contact you directly.

Best regards,
Christophe Van der Kelen
