What is the parallelism degree of OpenFOAM? Does it support the six hundred thousand cores (600K cores) parallel computing? Thanks!

Assuming that 600K cores are spread across at least a few thousand nodes my answer to your question is: No, probably not. I/O will be a bottleneck.

Did you have a chance to give it a try?
