SUMMARY:Tuning CFD Applications for Intel Xeon Phi with TAU Commander and 
 ParaTools ThreadSpotter
DESCRIPTION:Izaak B. Beekman and Nicholas Chaimov (ParaTools Inc); Sameer 
 Shende and Allen D. Malony (ParaTools Inc, University of Oregon); Nicholas
  Bisek and Ryan Gosse (US Air Force Research Laboratory); and Andrew Wissi
 nk (Create AV, US Army)\n\nTuning and understanding the performance charac
 teristics of computational fluid dynamics (CFD) codes on many-core, NUMA a
 rchitectures is challenging. One must determine how programming choices im
 pact algorithm performance and how best to utilize the available memory ca
 ches, high-bandwidth memory, and inter---and intra---node communication. O
 nce collected, performance data must be translated into actionable code im
 provements. In addition, performance engineering experiments must be organ
 ized and tracked to quantify the benefit of any attempted tuning.\n\nIn th
 e poster we present, examine and tune two CFD applications running on the 
 IntelⓇ Xeon Phi™️ partition of a CrayⓇ XC 40/50 using TAU Commander and Pa
 raTools ThreadSpotter. TAU Commander implements a streamlined, managed per
 formance engineering workflow and highlights source regions limiting scala
 bility through profiling and aggregate summary statistics. ParaTools Threa
 dSpotter analyzes an application as it is running and ranks individual per
 formance problems. It provides a report annotating source code lines with 
 actionable recommendations and quantifying performance metrics.\n\nRegistr
