My 0.02. Based on one of Moshe Bar's OpenMosix papers, Mosix increases the performance of MPI processes by load balancing. However I would have to say that this only works for compute bound processes. If there's going to be lots of I/O between nodes Mosix won't do so well and may very well degrade performance.
Did you run any benchmarks of NAMD + its parallel (CHARM?) implementation vs NAMD + CHARM + Mosix? Does it help? Last I checked the Mosix userland tools and some other key functionality still don't work for 2.6 linux kernels.
