History
PathScale was founded in 2001 as Key Research and its original mission was to develop clustered Linux server solutions based on a low-cost 64-bit design. In late 2003 the company came out of stealth mode and was called PathScale. The word PathScale is descriptive of the company's original design goals for clusters. In early 2003 with the success of the AMD Opteron, efforts at the company switched to other products like high-performance 64-bit compilers.
The seeds of the company were sown over 20 years ago at the Lawrence Livermore National Laboratory. Four of the company's seven founders all worked together building the S1 supercomputer back in the early 1980s. The first chief technical officer at PathScale, Tom McWilliams, had the initial idea for the company and incorporated in July 2001. He added three of his LLNL colleagues (Jeff Rubin, Jeff Broughton, Fred Chow) to the company shortly thereafter. McWilliams had been a company founder at Valid Logic Systems and Key Computer and worked at SGI, Sun Microsystems and Amdahl Corporation. Chow was formerly chief scientist for compilers at SGI and MIPS.
PathScale Inc. was acquired and re-sold several times. First by QLogic in February 2006, for about $109 million. It was acquired by SiCortex in August 2007, and by Cray in August 2009, when SiCortex was liquidated. Cray owned the intellectual property until March 2012 when a new PathScale Inc. acquired all assets.
On June 13, 2011, PathScale announced that the EKOPath 4 Compiler Suite would become open source software and licensed under the GPL.
The suite contains:
