SC08 Workshop — Sunday, November 16, 2008
Power Efficiency and the Path to Exascale Computing
Overview
Over the past forty years, progress in supercomputing has tracked progress in integrated circuit scaling, and this has resulted in exponential improvements in system-level performance. However, changes in device physics now seriously threaten further sustained progress toward exaflops HPC systems. This workshop will begin with a summary of a recent DARPA study highlighting issues associated with exaflops computing architecture. This will be followed by a series of invited talks covering a wide range of approaches to mitigating the exaflops computing roadblocks, including novel computer architectures, power-aware algorithm design, power efficiency metrics, and power efficient facility design.
