Interactive remote visualization of large-scale simulation using PBVR

Kawamura, Takuma 

I was invited from the Science Council of Japan for an invited lecture on In-Situ PBVR visualization technology. To develop visualization technology for future Exascale simulation, the following three problems are bottlenecks. (1) Increase of communication cost under high parallel environment. (2) Low interactivity due to offline visualization for batch processing. (3) Visualization of multivariate data. In order to solve these problems, I developed the following three technologies. (1) Parallel volume rendering with high scalability by PBVR. (2) Framework that enables interactive operation by file-based control via storage. (3) Multidimensional transfer function generation technique for multivariate data. Applying the proposed method to fuel melting simulation JUPITER about 100 million degrees of freedom, we demonstrated the high scalability of visualization processing, the interactive operation at batch processing execution, and the effectiveness of multivariate visualization function.
