Ardent Computer
The Ardent Computer Corporation was a graphics minicomputer manufacturing company. The systems also used the Intel i860 as graphics co-processors. The company went through a series of mergers and re-organizations and changed names several times as their venture capital funders attempted to find a market niche for their "graphics supercomputers". After a series of machines that were not particularly successful in the marketplace, they used parts of their design to create graphics subsystems for other workstations, notably DEC machines, but eventually shut down completely in February 1995.
==Origins==
Ardent started as Dana Computer, Inc. in November 1985 in Silicon Valley. Their aim was to produce a desktop multiprocessing supercomputer dedicated to graphics that could support up to four processor units. Each processor unit consisted initially of a MIPS R2000 CPU, and later a R3000, connected to a custom vector processor. The vector unit held 8,192 sixty-four-bit registers that could be used in any way from 8,192 one-word to thirty-two 256-word registers. This compares to modern SIMD systems which allow for perhaps eight to sixteen 128-bit registers with a small variety of addressing schemes.
Ardent software ran on Unix System V Release 3 with proprietary support for the four-way SMP and the vector processor. The compiler was based on the Convex Fortran (and C) compiler. Their significant graphics system for visualization was DORE (Dynamic Object Rendering Environment).
After learning that the name Dana was already in use by a local disk drive company, they became Ardent. Their business plan called for their ''Titan'' system to outperform anything in the market, to be ready for beta testing in July 1987, and sell at a price of around $50,000. By late 1986, it was clear their estimates were unrealistic, the machine was still not ready and considerably more development was needed. A second round of funding was provided by Kubota Corporation, a Japanese heavy industries player (best known in North America for their tractors) who was cash-flush and looking for new opportunities. Kubota agreed not only to fund the completion of the Titan but also to provide production facilities in Japan. By the time it was finally ready for testing in February 1988, the performance leadership position of Titan had been eroded, and the price had risen to $80,000.
