Performance Improvement of Seismic Analysis in a Large Scale Interactive Visualization

High performance scientific interactive visualization in post-processing deals with very large unstructured datasets from the outputs of simulations, which gradually slows down the system because of frequent memory allocation and release. In this paper, we implemented a cell mode of memory pool where one memory cell is allocated or released each time according to a given memory size. The results of test cases show that cases with memory pool techniques can effectively reduce memory fragmentation and fasten the data access speed. In finite element analysis, it can improve the operational efficiency about 20 times. In case study, seismic analysis of a junction box was conducted as an example to evaluate the advanced technologies of the finite element post-processing for large-scale structures.
