Correct me if I'm wrong, but don't the Cray's have relatively short (64?) element vector registers with relatively short pipelines compared to some of the earlier attempts at vector processors? The result of the short pipelines is that you get your first result faster, which is a real win on short vectors. -- Roy Smith, {allegra,cmcl2,philabs}!phri!roy System Administrator, Public Health Research Institute 455 First Avenue, New York, NY 10016
