Parallelization of AVS/Express

Abstract

To visualize large data at high speed, parallelization is required. We developed parallelized volume rendering module in the visualization software AVS/Express. In general, it is not easy to change existing source codes. In this paper, the volume rendering module is parallelized in three ways : auto-parallelization, OpenMP and pthread. We compare these methods in parallelized performance and difficulty of the coding.
