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.
