This led me to SUNMOS (OS for parallel processing, Sandia's alternative for the aforementioned intel PSC descendants) http://en.wikipedia.org/wiki/SUNMOS. Sandia's page looks like real progress for inertial containment sustainable thermonuclear fusion, which really wouuld be super duper cool, fuel your zeppelin with seawater, but I can't find latter-day references to SUNMOS. Anybody know what became of it? Thanks, Peter

Which is why Intel went to the "8 port switch in each node" sort of architecture with the iPSC/2. The iPSC/1 got icky with having to keep adding ethernet cards into each node. The iPSC/2 went to a packaging with each node on a single card, with two flavors of nodes, depending on whether it had a numeric/vector coprocessor or not. You could put 128 nodes in a single rack, as I recall.
