Thanks. I have found that the following seems to work for most systems: Loosely Coupled: each processor has its own local memory and IO resources. Tightly Coupled: processors are not bound to particular memory or IO resources (implies high bandwidth interconnections). To get a more general definition CONCISEness goes out the window. --- Peter Richardson, ACSnet: peter@trlsasy.trl.oz Telecom Research Laboratories, UUCP: {uunet,mcvax}!trlsasy.trl.oz!peter PO.
