Ok, point taken about dynamic spawning of new processes. We have hot code loading and modules in Chicken. MPI has MPI_Disconnect,MPI_Wait and MPI_Test, which are not incorporated in the mpi egg, but could be used for monitoring process termination. The group communication facilities of MPI are useful for a much wider variety of situation than numerical algorithms. Very complicated datastructures can me modeled by an MPI topology. Cartesian topology is just that -- a set of processes (nodes) in which every process sends a message to every other process. MPI doesn't know anything about matrix operations or weather, it just knows about group topology, communication, and data structures.
