SUMMARY:Top-Down Performance Analysis of Workflow Applications
DESCRIPTION:Poster\nTech Program Reg Pass, Exhibits Reg Pass\n\nTop-Down P
 erformance Analysis of Workflow Applications\n\nHerold, Williams\n\nScient
 ific simulation frameworks are common to use on HPC systems. They contain 
 parallelized algorithms and provide various solvers for a specific applica
 tion domain. Usually, engineers execute multiple steps to solve a particul
 ar problem which are often distributed over multiple jobs. Finding perform
 ance bottlenecks and the causing step in such a complex system is very dif
 ficult.  Therefore in this work, we present a top-down approach that provi
 des summarized performance metrics for the workflow, jobs and job steps. T
 hese summaries guides the user to identify inefficiencies and determine th
 e causing job step. Finally, Vampir can be used for a detailed analysis of
  the regarding execution in order to resolve the issue.
