Is it possible to have Elmer running on a pc-cluster ? it could be interesting to reduce calculation time.

Re: Elmer on a pc-cluster
Should this procedure works also for Elmer ? it's based on MPI as Elmer does for paralleling processes.
Re: Elmer on a pc-cluster
If someone is interested i'm writing a wiki on how to easily split elmer simulation on a DIY cluster using common pcs and MPI
Re: Elmer on a pc-cluster
Hello Pisolino,
yes, we tested the possibility over here, too, some two years ago. The main objective was to use computers of the same bit size - coupling 32-bit systems with 64-bit systems did NOT work.
We did not pursue this direction as for our problems there was not much sense in further domain splitting.
But if you are writing a wiki anyhow that would be nice to know about. Maybe we may return to that approach some time in the future and can contribute some minor details.
Regards,
Peter

Re: Elmer on a pc-cluster
It looks like no one posted to this, so I'll throw in my 2 cents: I have a beowulf cluster using LAM and OpenMPI, and Elmer works great on it (just set up your processes to use the extra machines). That said, one of my machines is a lot faster than the others, so it definitely ends up doing most (80%) of the work, but there is a speed up when then other machines are pulled in...
