Google-Wide Profiling: A Continuous Profiling Infrastructure for Data Centers
Abstract: 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.
