Around 20 of these systems were built from 1996 until 2000. The T90 reintroduced the idea of total immersion cooling
Cray J90 Range
Cray J90 Range The Cray-J90 range of computers were manufactured from 1994 until 1998. This air cooled system replaced the EL range providing more and faster processors with bigger memories using traditional single system image and global memories. The first system had up to 16 CPUs with later version including a new I/O subsystem and
Cray T3E
Cray T3E The Cray-T3E range of computers were manufactured from 1996 until 2002. The T3E continued the use of large numbers of commodity processors and distributed memory. Evolving from the T3D the T3E was a stand-alone computer which ran both parallel and single node applications concurrently. Around 100 of these machines were manufactured, and many
