If your communication requirements are not too high then you could just communicate through one socket (with everybody listening), whereby the first byte would indicate which machine the message was for (assuming < 255 machines) Of couse you have esentially "sequentialized" all communication here. Note this is != to sequentializing all processing! How much/how frequent is the communication? ---Ashmeet Sidana sidana@cs.stanford.edu Stanford University.

It would be a good thing if you also looked into the ISIS toolkit from Cornell University wich gives you must of the tools you need for distributed computing under UNIX.
