SUMMARY:Top-Down Performance Analysis of Workflow Applications
DESCRIPTION:Christian Herold and Bill Williams (Technical University Dresd
 en)\n\nScientific simulation frameworks are common to use on HPC systems. 
 They contain parallelized algorithms and provide various solvers for a spe
 cific application domain. Usually, engineers execute multiple steps to sol
 ve a particular problem which are often distributed over multiple jobs. Fi
 nding performance bottlenecks and the causing step in such a complex syste
 m is very difficult.  Therefore in this work, we present a top-down approa
 ch that provides summarized performance metrics for the workflow, jobs and
  job steps. These summaries guides the user to identify inefficiencies and
  determine the causing job step. Finally, Vampir can be used for a detaile
 d analysis of the regarding execution in order to resolve the issue.\n\nRe
