Abstract

Thermal-Hydraulics computing softwares play an important role in nuclear reactor design and safety analysis. Among them, Nek5000 is an excellent open-source Computational Fluid Dynamics based Thermal-Hydraulics computing software. To in-depth investigate the performance of Nek5000, Exascale Simulation of Advanced Reactors research group has developed Nekbone mini-application. Nek5000 resembles the kernel basic structure and functionalities of the complete Nek5000 software. We investigate the weak and strong scaling performance on two Chinsed supercomputers which are Tianhe II and Era. Tianhe II was crowned as the fastest supercomputer in 2013 by TOP500 list. The average MFlops and Time-scaling performance metric represent the excellent weak scaling performance of Nekbone on both Tianhe II an Era supercomputers.
