SUMMARY:Information Entropy-Based Camera Focus Point and Zoom Level Adjust
 ment for Smart In-Situ Visualization
DESCRIPTION:Taisei Matsushima, Ken Iwata, and Naohisa Sakamoto (Kobe Unive
 rsity, Japan); Jorji Nonaka (RIKEN Center for Computational Science (R-CCS
 )); and Chongke Bi (Tianjin University, China)\n\nIn-situ processing has w
 idely been recognized as an effective approach for the visualization and a
 nalysis of large-scale simulation outputs from modern HPC systems. However
 , traditional batch-based in-situ visualization can produce large amounts 
 of rendering results for post-hoc visual analysis, which can make it diffi
 cult to gain rapid insight into the simulation results during post-hoc vis
 ual analysis. As an alternative to accelerate the process of obtaining sci
 entific knowledge, we have worked on a smart visualization approach,  focu
 sing on extracting a set of images that may facilitate the rapid understan
 ding of the underlying simulated phenomena. In this work, we present a met
 hod for automatically adjusting the camera focus point and zoom level duri
 ng in-situ visualization. We integrated the proposed approach with the exi
 sting in-situ smooth camera path estimation method for evaluation purposes
  and used two CFD simulation codes and two HPC systems (x86 Server and Arm
 -based Fugaku supercomputer) for the evaluations.\n\nTag: Data Analysis, V
