ALPHA

(language)
(Or "Input") An extension of ALGOL 60 for the M-20 computer developed by A.P. Ershov at Novosibirsk in 1961. ALPHA includes matrix operations, slices, and complex arithmetic.

1. <tool> A compiler generator written by Andreas Koschinsky <koschins@cs.tu-berlin.de> and described in his thesis at the Technische Universitaet Berlin. Alpha takes an attribute grammar and uses Bison and Flex to generate a parser, a scanner and an ASE evaluator (Jazayeri and Walter).

(2) A family of RISC-based, 64-bit CPUs and computer systems from HP. Originally developed by Digital, which was acquired by Compaq and then HP, the first model introduced in early 1992 was the 150 MHz 21064-AA, considered equivalent to a Cray-1 on a single chip. Subsequent Alpha models continued to blaze the trails for high-speed microprocessors. Alpha-based servers (AlphaServers) run under Tru64 Unix and OpenVMS. In the mid-1990s, Windows NT was ported to the Alpha platform, but support was later dropped.

Alpha Went to Intel
In 2001, Compaq sold all Alpha intellectual property to Intel and announced it would switch its high-end servers to Intel's Itanium processors by 2004. HP acquired Compaq in 2002 and introduced enhanced AlphaServers. Orders were accepted for the new machines until April 2007, and support and service were promised until 2012.
