SUMMARY:ParaViz3D: MPI Trace Visualization with 3D Video
DESCRIPTION:Jean-Yves Verhaeghe, Georg Hager, and Ayesha Afzal (Friedrich-
 Alexander-Universität Erlangen-Nürnberg, Erlangen National High Performanc
 e Computing Center)\n\nConventional MPI trace visualizations become unwiel
 dy as the number of processes increases. Identifying global patterns is ch
 allenging, and both the underlying machine topology and parallel program s
 tructure are often obscured by the rigid two-dimensional rank-time graphs.
  To address these limitations, we propose a three-dimensional video visual
 ization of MPI programs that adapts its spatial layout to both the machine
  topology and the parallel decomposition of the numerical problem, while m
 apping process time evolution to actual video playback time.\n\nUsing Blen
 der, we develop a framework that automatically translates MPI trace data i
 nto 3D visual scenes. We explore various display choices, including color-
 time gradients and transparency, to enhance interpretability. Our approach
  provides a new, intuitive exploration of both large-scale and local behav
 iors and patterns. We showcase the utility of this method with idle wave a
 nd process desynchronization phenomena.\n\nTag: Research & ACM SRC Posters
