SUMMARY:ProTools 2020: Workshop on Programming and Performance Visualizati
 on Tools
DESCRIPTION:Workshop\n\nProTools – Introduction: Workshop on Programming a
 nd Performance Visualization Tools\n\nBhatele, Boehme, Geimer, Knuepfer\n\
 nUnderstanding program behavior is critical to overcome the expected archi
 tectural and programming complexities, such as limited power budgets, hete
 rogeneity, hierarchical memories, shrinking I/O bandwidths and performance
  variability, that arise on modern HPC platforms. To do so, HPC software d
 evelo...\n\n---------------------\nExascale Potholes for HPC: Execution Pe
 rformance and Variability Analysis of the Flagship Application Code HemeLB
 \n\nWylie\n\nPerformance measurement and analysis of parallel applications
  is often challenging, despite many excellent commercial and open-source t
 ools being available. Currently envisaged exascale computer systems exacer
 bate matters by requiring extremely high scalability to effectively exploi
 t millions of pro...\n\n---------------------\nOpenACC Profiling Support f
 or Clang and LLVM Using Clacc and TAU\n\nCoti, Denny, Huck, Lee, Malony...
 \n\nSince its launch in 2010, OpenACC has evolved into one of the most wid
 ely used portable programming models for accelerators on HPC systems today
 .  Clacc is a project funded by the US Exascale Computing Project (ECP) to
  bring OpenACC support for C and C++ to the popular Clang and LLVM compile
 r infras...\n\n---------------------\nProTools – Break\n\n\n\n------------
 ---------\nEmpirical Modeling of Spatially Diverging Performance\n\nCaloto
 iu, Geisenhofer, Kummer, Ritter, Weber...\n\nA common simplification made 
 when modeling the performance of a parallel program is the assumption that
  the performance behavior of all processes or threads is largely uniform. 
 Empirical performance-modeling tools such as Extra-P exploit this common p
 attern to make their modeling process more noise ...\n\n------------------
 ---\nSimulation-Based Performance Prediction of HPC Applications: A Case S
 tudy of HPL\n\nXu, Jiang, Ibeid, Svilan, Bian\n\nWe propose a simulation-b
 ased approach for performance modeling of parallel applications on high-pe
 rformance computing platforms. Our approach enables full-system performanc
 e modeling: the hardware platform is represented by an abstract yet high-f
 idelity model and the computation and communication c...\n\n--------------
 -------\nUsability and Performance Improvements in Hatchet\n\nBrink, Lumsd
 en, Scully-Allison, Williams, Pearce...\n\nPerformance analysis is critica
 l for pinpointing bottlenecks in applications. Many different profilers ex
 ist to instrument parallel programs on HPC systems, however, there is a la
 ck of tools for analyzing such data programmatically.  Hatchet, an open-so
 urce Python library, can read profiling data fr...\n\n\nRegistration Categ
