COVER FE ATURE USING PERFORMANCE MODELING TO DESIGN LARGE- SCALE SYSTEMS

By Kevin J. Barker, Kei Davis, Adolfy Hoisie, Darren J. Kerbyson, Michael Lang and Scott Pakin

Abstract

A methodology for accurately modeling large applications explores the performance of ultrascale systems at different stages in their life cycle, from early design through production use. Increasingly, scientific discovery has relied on computer simulation, fueling an insatiable demand for ever-faster supercomputers. Such computers can deliver results sooner, often with higher fidelity. However, as supercomputers get faster, they also get more complex. While a high-end desktop computer might contain 16 processor cores, a single memory address space, and a simple, internal, all-to-all network connecting the cores, today’s fastest supercomputers—th
