Abstract

This paper evaluates the basic performance of the latest vector supercomputer, SX-Aurora TSUBASA, in order to clarify its potential. First, the memory bandwidth, which is one of the features of SX-Aurora TSUBASA, is evaluated by using the Stream benchmark. Next, the performances of the Himeno benchmark and the HPCG benchmark are examined. From these evaluations, it is clarified that the high sustained memory bandwidth can be achieved. It is also clarified that the high memory bandwidth of SX-Aurora TSUBASA can achieve the high sustained performance in other benchmarks compared to SX-ACE.
