The Cray-1 was a supercomputer designed, manufactured and marketed by Cray nuamooreaid.comced in , the first Cray-1 system was installed at Los Alamos National Laboratory in Eventually, over Cray-1's were sold, making it one of the most successful supercomputers in nuamooreaid.com: bit processor @ 80 MHz. The Cray Research, Inc. CRAY-1 Computer System is a large-scale, general-purpose digital computer featuring vector as well as scalar processing, a naaosecond clock period, d a 50 nanosecond memory cycle time. The CRAY-1 is able of executing over 80 million floating point operations. Cray-1 Supercomputer (#38) and Memorabilia at the DigiBarn (with special thanks to Tony Cole). Peruse the image galleries and story of our Cray-1 Supercomputer (serial number 38) which came from Livermore National Laboratories in Livermore, California. Also take a look at Cray-1 related documents and other memorabilia. Abstract. This Validation Summary Report (VSR) for the Cray Research, Inc., CRAY FORTRAN Translator (CFT) Version Bugfix 1 running under the CRAY Operating System (COS) Version provides a consolidated summary of the results obtained from the validation of the subject compiler against the FORTRAN Standard (X/FIPS PUB 69).

It was, in turn, replaced in that spot by the Cray Y-MP in The Cray-2 was the first of Seymour Cray's designs to successfully use multiple nuamooreaid.comcturer: Cray Research. Harry L.

The Cray-3 was a vector supercomputer, Seymour Cray's designated successor to the CrayThe 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 ( m 3) nuamooreaid.com design goal was performance around 16 GFLOPS, about 12 times that of the Cray

Code Warriors (book about the NSA) With the exception of a short-lived and still-classified breakthrough using Cray-1 supercomputers against Soviet codes, summary reports that did include a mention of signals relating to a North Vietnamese salvage operation obfuscated the timing to hide the fact that one of the recovered boats was.

The CRAY-1 system broke that barrier, and today vectorization techniques are used routinely by scientists and engineers in a wide variety of di~ciplinee. The GRAY XMP series of computer systems was Cray Research's fim and industry-standard codes to solve a wide range of problems. Additionally, software developed for.
