I presented the research result of "Remote Interactive In-Situ Visualization using Particle Data for Volume Visualization" founded by Joint Usage/Research Center for Interdisciplinary Large-scale Information Infrastructures (JHPCN), 2017. With increasing simulation scale, the conventional visualization process involving data transfer to the pre-post node requires a huge amount of work time. To enable real-time visualization and analysis of large-scale simulation, an interactive In-Situ visualization system using particle data for visualization was constructed in this research and this system was ported to the latest GPGPU, XeonPhi, and FX100 environments. Using this system, we confirmed that interactive visualization of batch processing simulations is possible.

The SPEEDI and its world version (WSPEEDI) were developed to predict the off-site diffusion behavior of radioactive substances covering wide areas at ~100km scale based on a mesoscale metrological model. In this work, we apply two new ingredients, GPUs and an adaptive mesh refinement (AMR) method to the lattice Boltzmann method (LBM). In this report, we confirmed the good scalability on the GPU-rich supercomputer, and our code can reproduce the wind tunnel experiment. We conclude that the present LBM is one of most promising approaches to realize a real-time simulation.
