Google-Wide Profiling: A Continuous Profiling Infrastructure for Data Centers
Gang Ren, Eric Tune, Tipp Moseley, Yixin Shi, Silvius Rus, Robert Hundt · IEEE Micro · 2010
Google-Wide Profiling (GWP), a continuous profiling infrastructure for data centers, provides performance insights for cloud applications. With negligible overhead, GWP provides stable, accurate profiles and a datacenter-scale tool for traditional performance analyses. Furthermore, GWP introduces novel applications of its profiles, such as application-platform affinity measurements and identification of platform-specific, microarchitectural peculiarities.
