SUMMARY:Performance Analysis of the CFD Solver CODA – Harnessing Synergies
  between Application and Performance Tools Developers
DESCRIPTION:Workshop\n\nPerformance Analysis of the CFD Solver CODA – Harn
 essing Synergies between Application and Performance Tools Developers\n\nT
 schueter, Huismann, Wesarg, Knespel\n\nAccurate prediction of fluid flows 
 remains an important field of research and engineering. To this end, compu
 tational fluid dynamics is widely employed. Due to their high demands on c
 omputational resources CFD applications profit from HPC systems. Continuou
 s performance analysis and optimization is key to efficient utilization of
  HPC resources. This paper demonstrates the beneficial cooperation between
  developers of HPC software and performance tools in the context of the CF
 D solver CODA and the sparse linear system solver Spliss. We investigate c
 oncepts used by CODA/Spliss to achieve high scalability, evaluate their ef
 fectiveness with performance analysis tools, and illustrate profits obtain
 ed from a close collaboration between HPC application and tool developers.
  Tools support developers in analyzing/tuning their applications. Feedback
  and requests of developers inspire tools enhancements. We highlight these
  aspects with an extended support of non-blocking collectives in performan
 ce tools and emphasize the need for sophisticated tool support of multi-th
 readed MPI applications.\n\nSession Format: Recorded\n\nRegistration Categ
