OpenFOAM and load balancing

March 18, 2008, 16:54

Hello everybody

I am a newbie in OpenFOAM. I have access to a hetergenous cluster and I am wondering if OpenFOAM has any tools to make an optimal load balancing, i.e. that the slower machines will get a less time expensive job than the faster machines. Does anyone has a tip.

Thanks in advance
Dominik

Hi Dominik,
Yes you can specify different loads for different nodes when you decompose your case using metis decomposition method.
See this: running in parallel.
