Abstract: Remote Visualization for Large-Scale Simulation Using Particle-Based Volume Rendering

With the recent development of supercomputers, it is required to efficiently visualize the results of extremely large-scale numerical simulations with a few hundreds to several tens of thousands of parallel processes. Conventional offline-processing visualization approaches are facing difficulties such as transferring large-scale data and reassembly of extensive amount of computational result files, which are inevitable for sort-first or sort-last visualization methods [1]. On the other hand interactive visualization on a supercomputer is still limited. We propose a remote visualization system which has three features. First, our visualization system can avoid the reassembly of the result files. This system can generate rendering primitives on the same number of parallel processes of the numerical simulation. Second, this system enables users to interactively manipulate camera position and time progress. Third, this system is appropriate to overview entire physical values of computational space (volume data) by volume rendering.
