The T3D was designed to be hosted by a Cray Y-MP Model E, M90 or C90 -series "front-end" system and rely on it and its UNICOS Operating System for all I/O and most system services. The T3D PEs ran a simple Microkernel called UNICOS MAX. Several different configurations of T3D were available. The ''SC'' (Single Cabinet) models shared a cabinet with a host Y-MP system and were available with either 128 or 256 PEs. The ''MC'' (Multi-Cabinet) models were housed in one or more liquid-cooled cabinet(s) separately from the host, while the ''MCA'' models were smaller (32 to 128 PEs) air-cooled multi-cabinet configurations. There was also a liquid-cooled ''MCN'' model which had an alternative interconnect wiremat allowing non-power-of-2 numbers of PEs. The Cray T3D MC cabinet had an Apple Macintosh PowerBook laptop built into its front. Its only purpose was to display animated Cray Research and T3D logos on its color LCD screen. The T3D was superseded in 1995 by the faster and more sophisticated Cray T3E . |
