In visualizing large-scale data on remote strage, existing remote visualization tools have bottlenecks in the processing speed, the memory size, and the data transfer. Client/Server visualization system using Particle-based volume rendering resolves these bottlenecks by converting large-scale data into small visualization particles. We developed this system for supercomputer and tuned particle generation process for the parallel distributed environment. Our system achieved strong scaling with high parallel efficiency over 90%.
