SUMMARY:AppEKG: A Simple Unifying View of HPC Applications in Production
DESCRIPTION:Workshop\n\nAppEKG: A Simple Unifying View of HPC Applications
  in Production\n\nAl-Tahat, Trecakov, Cook\n\nWhile many good development-
 oriented tools exist for analyzing and improving the performance of HPC ap
 plications, capability for capturing and analyzing the dynamic behavior of
  application in real production runs is lacking. Many heavily-used applica
 tions 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 A
 ppEKG, both a concept of and a prototype tool for providing a unified, und
 erstandable view of HPC application behavior in production. Our prototype 
 AppEKG framework can achieve less than 1% overhead, thus usable in product
 ion, and still provide dynamic data collection that captures time-varying 
 runtime behavior.\n\nSession Format: Recorded\n\nTag: Applications, Archit
 ectures, Benchmarking, Exascale Computing, Modeling and Simulation, Perfor
 mance, Performance Portability\n\nRegistration Category: Workshop Reg Pass
