AbstractJapan Aerospace Exploration Agency (JAXA) has installed a new lOO-terascale massively parallel supercomputer system as part of the JAXA Supercomputer System (JSS) for aerospace science and engineering research purposes. It is in full operation from April 2009. In this study, we investigate and evaluate the performance of CPU operation and memory access of the system by using an unstructured NS solver, and found that the new system has an expected high performance compared with the previous system. However, we also found that for high efficiency to applications, the issues on load unbalance and recursive reference can be further considered.
