Abstract
This paper presents the new supercomputer system NEC SX-9 that has been installed at Tohoku University in March 2008. The performance of the system is evaluated by using six real application codes. The experimental results indicate that the SX-9 system achieves a speedup of up to 7 compared to our previous NEC SX-7 system for the single-CPU sustained performance. In addition, the paper examines the effects of an on-chip vector cache named ADB on the performance, and confirms performance increases between 20 and 70% by selective caching on ADB.
