AppEKG: A Simple Unifying View of HPC Applications in Production
DescriptionWhile many good development-oriented tools exist for analyzing and improving the performance of HPC applications, capability for capturing and analyzing the dynamic behavior of application in real production runs is lacking. Many heavily-used applications do keep some internal metrics of their performance, but there is no unified way of using these. In this paper we present the initial idea of AppEKG, both a concept of and a prototype tool for providing a unified, understandable view of HPC application behavior in production. Our prototype AppEKG framework can achieve less than 1% overhead, thus usable in production, and still provide dynamic data collection that captures time-varying runtime behavior.
