AB  - Extracting and analyzing detailed information from largesimulations is of crucial importance for science. However, with the in-creasing problem size of nowadays simulations, the process of visualizingand understanding big simulation raw data becomes more difficult andneeds additional effort. More precisely, the gap between compute and I/Operformance is widening with current supercomputers. Thus, the classi-cal approach of visualizing simulation results in a post-processing stepis limited or even impossible for extreme-scale scenarios. One promisingtechnique to overcome this issue is in situ visualization, which visual-izes and analyzes simulation data on simulation runtime. Within thiswork, in situ visualization using VisIt/Libsim has been added to theCIAO code framework for interactive- and batch-mode visualization onJUQUEEN, an IBM Blue Gene/Q system with 458 752 cores. Full-systemruns are demonstrated and early-results of performance measurementsof an extreme-scale multiphase case are discussed.
