SUMMARY:Differential Performance Analysis Workflow for Algorithmic Changes
DESCRIPTION:Workshop\n\nDifferential Performance Analysis Workflow for Alg
 orithmic Changes\n\nThärigen, Protze, Orland, Hermanns\n\nMost performance
  analysis tools used in HPC focus on a single configuration of an applicat
 ion.  In this work, we instead present a novel performance analysis workfl
 ow, supporting the in-depth comparison of varied code versions and running
  conditions. \n\nThere exist different code versions for many applications
  because they comprise parts that can be implemented in various ways or al
 ready exist in third-party libraries, like linear solvers.  What is the im
 pact of replacing a solver to the rest of the application?  Such measureme
 nts are often not supported directly and are cumbersome to handle manually
  with current performance measurement and analysis tools.  We present a wo
 rkflow that handles the multitude of measurements and data collation.  Fur
 thermore, we introduce diagrams suited for a clear presentation of the col
 lected performance data.  Our application studies with CalculiX and Jukkr 
 highlight that our workflow allows a detailed performance analysis while s
 till being easy to use.\n\nTag: Online Only, Heterogeneous Systems, Perfor
