SUMMARY:Practical Hybrid Parallel Application Performance Engineering
DESCRIPTION:Tutorial\n\nPractical Hybrid Parallel Application Performance 
 Engineering\n\nGeimer, Shende, Williams, Wylie, Ziegenbalg\n\nThis tutoria
 l presents state-of-the-art performance tools for leading-edge HPC systems
  founded on the community-developed Score-P instrumentation and measuremen
 t infrastructure, and demonstrates how they can be used for performance en
 gineering of effective scientific applications based on standard MPI, Open
 MP, hybrid combination of both and increasingly common usage of accelerato
 rs. Parallel performance tools from the Virtual Institute - High Productiv
 ity Supercomputing (VI-HPS) are introduced and featured in exercises with 
 Score-P, Scalasca, Vampir and TAU. Emphasis is placed on analyzing measure
 ment results and how tools are used in combination for identifying perform
 ance problems and investigating optimization alternatives. Using their own
  notebook computers with a provided HPC Linux [http://www.hpclinux.org] OV
 A image containing all the necessary tools, participants will be able to w
 ork through the exercises on their own with provided example measurements 
 collected on contemporary HPC systems. This will help to prepare participa
 nts to locate and diagnose performance bottlenecks in their own parallel p
 rograms.\n\nTag: Debugging, Heterogeneous Systems, Performance/Productivit
