ILLIAC IV
The ILLIAC IV was one of the first attempts to build a massively parallel computer. One of a series of research machines (the ILLIACs from the University of Illinois), the ILLIAC IV design featured fairly high parallelism with up to 256 processors, used to allow the machine to work on large data sets in what would later be known as vector processing. After several delays and redesigns, the computer was delivered to NASA's Ames Research Center at Moffett Airfield in Mountain View, California in 1971. After thorough testing and four years of NASA use, ILLIAC IV was connected to the ARPANet for distributed use in November 1975, becoming the first network-available supercomputer, beating Cray's Cray-1 by nearly 12 months.
