FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -Examples of special-purpose supercomputers include Belle, Deep Blue, and Hydra for playing chess, Gravity Pipe for astrophysics, MDGRAPE-3 for protein structure prediction and molecular dynamics, and Deep Crack for breaking the DES cipher.

Detailed explanation-3: -TECH STORY: The Cray Y-MP was the world’s first supercomputer to sustain over 1 gigaflops. Considered a follow-on to the X-MP, the initial system had eight parallel vector processors, denser circuits and a larger central memory. The Y-MP reached a peak speed of 2.67 gigaflops.

Detailed explanation-4: -The Cray-3 was a vector supercomputer, Seymour Cray’s designated successor to the Cray-2. The system was one of the first major applications of gallium arsenide (GaAs) semiconductors in computing, using hundreds of custom built ICs packed into a 1 cubic foot (0.028 m3) CPU.
