| After decades of continuous scaling, further advancement of silicon microelectronics across the entire spectrum of computing applications is today limited by power dissipation. While the trade-off between power and performance is well-recognized, most recent studies focus on the extreme ends of this balance. By concentrating instead on an intermediate(More)

Germann M. J. Jeanson As 1999 ended, IBM announced its intention to construct a onepetaflop supercomputer. The construction of this system was based on a cellular(More)
Short, medium, and long on-chip interconnections having linewidths of 0.45–52 m are analyzed in a five-metallayer structure. We study capacitive coupling for short lines, inductive coupling for medium-length lines, inductance and resistance of the current return path in the power buses, and line resistive losses for the global wiring. Design guidelines and(More)
BlueGene/L (BG/L) is a 64K (65,536) node scientific and engineering supercomputer that IBM is developing with partial funding from the United States Department of Energy. This paper describes one of the primary BG/L interconnection networks, a three dimensional torus. We describe a parallel performance simulator that was used extensively to help architect(More)
We present here a report produced by a workshop on ‘Addressing failures in exascale computing’ held in Park City, Utah, 4–11 August 2012. The charter of this workshop was to establish a common taxonomy about resilience across all the levels in a computing system, discuss existing knowledge on resilience across the various hardware and software layers of an(More)
