In this study, we present a series of benchmarks that exploit virtualization features using IBM POWER5 technology and IBM AIX 5L Version 5.3. We define virtual benchmarks (VBs) based on new functionality introduced in the IBM eServer iSeries and pSeries POWER5 technology-based systems and AIX 5L Version 5.3. The benchmarks selected rely on virtualization exploitation through Micro-Partitioning. The applications tested in this study correspond to Gaussian 03 Rev. C.01, BLAST 2.2.6, and AMBER 7. We show that throughput benchmarks running on a system with Micro-Partitioning can take full advantage of a pool of shared processors. In other words, virtual processors improve the time to solution.
