Hi All, Though not with MASON, but with Repast, we are using a Proactive based approach. We found that it works better than MPI (more intuitive to use, etc.) and it's fully compatible with Java. It should also work for MASON, I think. Others with Repast are known using Terracotta for similar purposes. I hope this helps, -- gulya -- dr.
