Biography

Kevin Pedretti is a Principal Member of Technical Staff at Sandia National Laboratories. He has helped develop several large-scale parallel computers, including the Red Storm system that was productized as the Cray XT line of supercomputers and Astra, the first Petascale supercomputer based on Arm processors. Prior to joining Sandia in 2001, he studied engineering at the University of Iowa where he received a B.S.E. in Electrical Engineering in 1999 and an M.S. in Computer Engineering in 2001. His current research interests include operating systems for massively parallel supercomputers, high-performance and scalable networking, power management, and hardware virtualization in the context of high performance computing.
