The T3E line is an Massively Parallel computer (MPP) - it uses up to 4096 alpha processors for a single machine. The T90 line is is a Parallel Vector it does not use alpha but is a genuine descendent of the original Cray 1. Cray 1 -> Cray XMP -> Cray YMP -> Cray C90 -> Cray T90. It comes in two variants - standard cray floating point and IEEE floating point. I do not know if it is 100% IEEE compliant. -- Brian Hanson -- brh@cray.com
