I used MPI (Message Passing Interface...) back in the day. But it was a pain, especially since our code was a mix of c (which was easy to mpi) and ada (not so easy). Its pretty low level stuff (I think we used Open MPI). All the nodes need to have MPI set up and configured, fine if you have a team willing to do it but these days.... mpiexec -n 10 myprocess I think we liked it because the processes would be put to sleep by the mpi daemon until a message arrived. You can sleep and wait for a message with sockets now I think. Its been a while since I've used the unix IPC (Interprocess communication). I don't think I'll miss it. |
