The Cray-4 was intended to be Cray Computer Corporation's successor to the failed Cray-3 supercomputer. It was marketed to compete with the T90 from Cray Research.

<company> US manufacturer of large powerful mainframe supercomputers, co-founded by noted computer architect, Seymour Cray. Quarterly sales $216M, profits $8M (Aug 1994). Cray were bought by Silicon Graphics, Inc.. [More details?] (1999-10-19)

<person> The founder of Cray Research and designer of several of their supercomputers. Cray has been a charismatic yet somewhat reclusive figure. He began Cray Research in Minnesota in 1972. In 1988, Cray moved his Cray-3 project to Colorado Springs. The next year, Cray Research spun it off to create Cray Computer. In 1989, Cray left Cray Research and started Cray Computer Corporation in Colorado Springs. His quest to build a faster computer using new-generation materials failed in 1995, and his bankruptcy cost half a billion dollars and more than 400 jobs. The company was unable to raise $20 million needed to finish the Cray-4 and filed for bankruptcy in March 1995. In the summer of 1996, Cray started a Colorado Springs-based company called SRC Computers, Inc. "We think we'll build computers, but who knows what kind or how," Cray said at the time. "We'll talk it over and see if we can come up with a plan." On 1996-09-22, aged 70, Cray broke his neck in a car accident. Surgery for massive head injuries and swelling of the brain leaving him in a critical and unstable condition. (1997-03-02)

The Cray Superserver 6400, or CS6400, is a discontinued multiprocessor server computer system produced by Cray Research Superservers, Inc., a subsidiary of Cray Research, and launched in 1993.

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 CPU.

The Cray C90 series (initially named the Y-MP C90) was a vector processor supercomputer launched by Cray Research in 1991. The C90 was a development of the Cray Y-MP architecture.

The Cray CX1 is a deskside high-performance workstation designed by Cray Inc., based on the x86-64 processor architecture.

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.

Matthew 4:4 is the fourth verse of the fourth chapter of the Gospel of Matthew in the New Testament. Jesus, who has been fasting in the desert, has just been tempted by Satan to make bread from stones to relieve his hunger, in this verse he rejects this idea.
