Is mpiJava dependent on a specific vesion of MPI? Not only is MPICH-1.2.5 a quite old version of the MPICH release, the entire series has been superceeded by MPICH2 (unless you require heterogenerous support). does mpijava work with MPICH2-1.0.5 ? > I've also noticed that when a normal MPI program runs, the process tree > shows mpirun, which has a child of your program.

The job management in MPICH is a little hairy. Things have been cleaned up somewhat in MPICH2. For example, running MPICH2 progams under valgrind is a lot easier than doing so with MPICH1-based programs. Perhaps the same will hold for mpijava, though I know nothing about that project. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B _______________________________________________ Beowulf mailing list, [email protected] To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
