Each processor could have its own unshared address space and use a different mechanism for intentional sharing. I assume all big systems are shared-nothing message passing systems now. They certainly were seven years ago. One thing I don't know whether is happening is how related the geometry of problems is to the geometry of machines in terms of how tractable they are. If most of your communication is to neighbours that's going to help you. You can fiddle with the topology but you can't fiddle with the geometry in the limit. This is kind of far from Lisp now though. --tim _______________________________________________ Lisp Hug - the mailing list for LispWorks users [email protected] http://www.lispworks.com/support/lisp-hug.html
