Title: Intel Woodcrest: An Evaluation for Scientific Computing

Abstract

Intel recently began shipping its Xeon 5100 series processors, formerly known by their 'Woodcrest' code name. To evaluate the suitability of the Woodcrest processor for high-end scientific computing, we obtained access to a Woodcrest-based system at Intel and measured its performance first using computation and memory micro-benchmarks, followed by full applications from the areas of climate modeling and molecular dynamics. For computational benchmarks, the Woodcrest showed excellent performance compared to a test system that uses Opteron processors from Advanced Micro Devices (AMD), though its performance advantage for full applications was less definitive. Nevertheless, our evaluation suggests the Woodcrest to be a compelling foundation for future leadership class systems for scientific computing.
