What was the purpose of the Cray Y-MP?

The Cray Y-MP was a supercomputer sold by Cray Research from 1988, and the successor to the company’s X-MP. The Y-MP retained software compatibility with the X-MP, but extended the address registers from 24 to 32 bits. High-density VLSI ECL technology was used and a new liquid cooling system was devised.

What kind of operating system does Cray Y-MP use?

The Y-MP ran the Cray UNICOS operating system . The Y-MP could be equipped with two, four or eight vector processors, with two functional units each and a clock cycle time of 6 ns (167 MHz). Peak performance was thus 333 megaflops per processor.

What was the peak GFLOPS of the Y-MP?

The Y-MP had a measured GFLOPS of 2.144 and a peak GFLOPS of 2.667 in both 1988 and 1989. The Model D Y-MP was superseded in 1990 by the Y-MP Model E, which replaced IOS Model D with IOS Model E, providing twice the I/O throughput.

When did the Cray Y-MP M90 come out?

The Y-MP M90 was a large-memory variant of the Y-MP Model E introduced in 1992. This replaced the SRAM of the Y-MP with up to 32 GB of slower, but physically smaller DRAM devices. The Y-MP M90 was also available in variants with up to two, four or eight processors ( M92, M94 and M98 respectively).

How tall is the Cray Y-MP EL cabinet?

Standing quietly by the very impressive Cray-1 from the Royal Aircraft Establishment was a grey and red cabinet about 5 feet tall with a big red button on top. This diminutive Cray supercomputer is the self-contained, air cooled, Y-MP EL.

Who was the designer of the Cray X-MP?

The Cray X-MP was a supercomputer designed, built and sold by Cray Research. It was announced in 1982 as the “cleaned up” successor to the 1975 Cray-1, and was the world’s fastest computer from 1983 to 1985 with a quad-processor system performance of 800 MFLOPS. The principal designer was Steve Chen.
