Testing, Simulating, and Profiling Designated Problems for CASL

Abstract

Simulation is an essential step for future implementations of more efficient and safer reactor components. In nuclear Technology, this translates to cost, fuel, and waste reduction, and enhanced safety. The software Coolant Boiling in Rod Arrays – Two Fluid (COBRA-TF) is currently undergoing development and until now has not been profiled to measure its performance. This project presents profiling data and data analysis of the code’s performance. We profiled two different version of the software while simulating two different input files. The profile data extracted from the simulations provided developers a better understanding of the code’s behavior. The results of this project will help developers improve the code’s performance in future versions by identifying the most time consuming portions of the code. The project involved activities such as testing, simulation, running designated problems on different programs or environments, analyzing, and verifying the results, and providing feedback to the development team.
