本文介绍了NEC最新的矢量超级计算机SX-ACE。SX-ACE继承并改进了NEC的SX矢量架构，旨在提供卓越的持续性能，特别是针对内存密集型应用。为此，SX-ACE处理器实现了全球一流的GFLOPS单核性能和全球领先的GB/S每核内存带宽。此外，SX-ACE系统的设计目的是通过保持相同的系统性能，将功耗降低到十分之一，而占地面积仅为以前的SX-9型号的五分之一。在本文中，我们详细阐述了SX-ACE的设计概念、体系结构概述和实现。我们还讨论了SX-ACE在几个基准代码上的持续性能。评估结果表明，与SX-9相比，SX-ACE系统的持续性能和能效显著提高。
This paper describes an introduction of NEC’s brand-new vector supercomputer, SX-ACE. The SX-ACE, which inherits and improves the NEC’s SX vector architecture, is developed to provide superior sustained performance, especially for memory-intensive applications. For this purpose, the SX-ACE processor achieves the world’s top-class single core performance of 64 GFLOPS and the world’s leading memory bandwidth of 64 GB/s per core. Moreover, the SX-ACE system is designed to reduce power consumption to one-tenth with just one-fifth the floor space as compared to the previous SX-9 model by maintaining the same system performance. In this paper, we elaborate on the design concept, architectural overview, and implementation of the SX-ACE. We also discuss the sustained performance of the SX-ACE for several benchmark codes. The evaluation results demonstrate significantly improved sustained performance and power efficiency of the SX-ACE system in comparison with the SX-9.
