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,
