(Fujitsu Siemens Computers, Inc. (USA), Milpitas, CA, www.fujitsu-siemens.com) Fujitsu Siemens Computers USA is a wholly owned research and development subsidiary of Fujitsu Siemens Computers. It primarily develops clustering software for the Fujitsu Siemens Computers product line worldwide. Amsterdam is world headquarters for Fujitsu Siemens Computers, which is the leading IT vendor in Europe and offers a complete line of laptops, desktop PCs and Unix-based servers.

In the U.S., Siemens Computer Systems evolved out of Pyramid Technology, which was founded in 1981 by former HP employees. In 1995, Siemens Nixdorf acquired the company, and in 1998, split the computer operation into Siemens Computer Systems, a division of Siemens Information and Communications Products, while retail and banking systems moved to an independent company, Wincor Nixdorf (www.wincor-nixdorf.com). Over the years, the company introduced several product lines, including the Nile, Reliant and RM families, many of which include a high-speed mesh interconnect for symmetric multiprocessing (SMP).
