Hi!
Im am trying to configure Comsol 4.1 for parallel computing on a number of nodes (currently 3) on a Scientific Linux System using PBS.
I found out i had to set up a mp-daemon on each of the nodes an tried like this:
>cat $PBS_NODEFILE|uniq > mpd.hosts % generating Hostfile
>comsol mpd boot -f mpd.hosts -n 3 -r ssh % starting mp-daemons
A quick check via "comsol mpd trace" gives back all 3 nodes, the mpds are running on, apparently communicating with each other one or the other way.
How to start comsol itself, however, i am not sure. I tried it with
>comsol
i.e. without any parameters, but the other nodes are not used. Another attempt with
>comsol -nn 3 -mpirsh ssh
seems to generate a few comsol tasks (at least on the one node i can see using htop) but does not provide a comsol-GUI, so no interactive testing or working is possible.
Can anyone help me on this matter?
Best regards, Christian
