Performance enhancements and visualization for RSQSim earthquake simulator. Pekurovsky, D., Chourasia, A., Richards-Dinger, K. Interactive visualization is accessible at Įarthquake Simulation, High Performace Computing, Supercomputers, Performance, Scalability, Software We also summarize data management findings and discuss how the changes impact analysis and its future potential. In course of visualization work we recognized the need to transform the data from current form into a more scalable and manageable format. We have created a prototype web based tool for exploring this data interactively. Exploring this data is of vital importance to validate the simulator as well as to identify features of interest such as quake time histories, conduct analyses such as calculating mean recurrence interval of events on each fault section. RSQSim generates data catalog of millions of seismic events for thousands of years and their associated properties such as changes in slip, stress, etc. We also report final results from visualization work. Furthermore, we have improved the scaling of the initialization portion of the code and created a Github repository, for the first time, for the SCEC CISM project. This feature alone leads to up to 33% better performance and substantially improved scalability. This saves on calculation time, as well as makes the code more load-balanced due to less variable numbers of calculation steps. This is achieved by introducing a new feature of the code which uses an added physical constraint that allows a large reduction in the number of times when an iterative solve is called. We have continued to improve scalability efficiency of the code, mainly by reducing load imbalance. ![]() We have studied performance of the code in detail on supercomputers such as Blue Waters (NCSA/UIUC), Stampede (TACC) and Mira (Argonne). We report on progress of performance tuning and visualization for earthquake simulator code RSQSim. ![]()
