• Extending OMPT to Support Grain Graph Visualization 

      Langdal, Peder Voldnes (Master thesis, 2017)
      Because of physical constraints, performance gains of single-core processors has come to a halt. Computer architects have responded by adding multiple processor cores to their designs. However, for continued performance ...
    • Extending OMPT to Support Grain Graphs 

      Langdal, Peder Voldnes; Jahre, Magnus; Muddukrishna, Ananya (Journal article, 2017)
      The upcoming profiling API standard OMPT can describe almost all profiling events required to construct grain graphs, a recent visualization that simplifies OpenMP performance analysis. We propose OMPT extensions that ...
    • Generating Grain Graphs Using the OpenMP Tools API 

      Langdal, Peder Voldnes (Research report, 2017)
      Computers are becoming increasingly parallel. Many applications rely on OpenMP to divide units of work between a set of worker threads. Typically, this is done using parallel for-loops or tasking. Grain graphs is a recent ...
