A '99 paper I read about > Java MPI showed it to be 20 times slower than MPI in > C/C++/FORTRAN so I don't think that's a good bet :) I didn't know that Java MPI was that slow. However let me explain my application. The application will be written in C, but there are things such as user interfaces for managing the cluster, and other programs which will show realtime data etc. All this is well done by java, and efficiency is not an issue here. The core programs will be written in C. Another question I have is, can processes join an MPI cluster ? It seems that all processes have to call MPI_Init () first, but LAM does seem to have a way to spawn processes. viral
