Abstract

Recently, a new supercomputer top 500 list was announced. The top spot was held by IBM BlueGene/L, with the new world-record performance of 136 Teraflop/s. More interestingly, five of the top ten supercomputers are now BlueGene-based. I will present the design goals and innovative technologies that enable the BlueGene/L, which packs 64,000 processors in a room of only 100 square meters.

Short Biography

Dr. Kyung Dong Ryu is a Research Staff Member in the High Performance Computing Group at the IBM T.J. Watson Research Center in Yorktown Heights, NY. He is currently working in the End-to-End Vertical Performance Optimization project, focusing on IBM p-series servers and WebSphere middleware. He is also co-leading the Restructuring Distributed Systems (named, Blue Pencil) project.

Before joining IBM Research, he was an Assistant Professor at the Arizona State University, where his research focused on PC Grid and Operating Systems for High Performance Computing. As a faculty member, he was awarded two NSF grants as a co-PI and lead a few industrial research projects funded by the Research Consortium with Intel and Motorola. He published over 20 papers in premier international conferences and journals, including IEEE/ACM SC, ACM ICS, IEEE IPDPS and IEEE TPDS. He is currently an Executive Committee Member for the IEEE Technical Committee on Parallel Processing (TCPP) and the president for the Korean Computer Scientists and Engineers Association in America (KOCSEA). He received a B.S. in 1993 and a M.S. in 1995 from the Seoul National University in Computer Engineering, and a Ph.D. in 2001 from the University of Maryland, College Park, in Computer Science.
