As a message passing system, the lam implementation seemed to us more robust and nicely integrated with POSIX systems. AFAIK the mpich is a bit older, we used to code with it in our distributed systems course 2 1/2 years ago. LAM is easier to use, etc.. And in the performance tests, it did as well as arch-specific code on IBM Cognitive Computer on our research cluster. For beowulf apps, I'd suggest that using LAM is a lot nicer. The older environments are always usable, but you will for instance find few projects that use pvm on their new beowulf code. However, I am not saying in any way that lam outperforms or surpasses mpich in many ways because we were simply more comfortable using lam, thus we'd be more glad if parallel programs had a version linked against lam. :) IMHO, it's always best to have as many alternatives as possible. That's why free software is so widespread on Beowulf systems. Regards, -- Eray (exa) Ozkural Comp. Sci.
