Steve Scott (computer architect)

Steve Scott is an American computer architect best known for his work at Cray. He joined the Cray organisation in 1992, then Cray Research and later Silicon Graphics, and rose to chief technology officer of Cray Inc. He was one of the architects of the Cray T3E multiprocessor, where he focused on the interconnect and on synchronization and communication mechanisms, and he was chief architect of the GigaRing system area network used in all Cray systems in the late 1990s. He was chief architect of the Cray X1 and X1E supercomputers, which combined high-performance vector processors with a scalable, globally addressable system architecture, and of the follow-on BlackWidow system. He also designed the router used in the Red Storm system at Sandia National Laboratories and the Cray XT3, and led the Cray Cascade project within the DARPA High Productivity Computing Systems program. He earned a PhD in computer architecture from the University of Wisconsin, Madison in 1992 and received both the 2005 ACM Maurice Wilkes Award and the 2005 IEEE Seymour Cray Computer Engineering Award.
