当前的超级计算机往往追求更高的峰值性能，然而，科学应用的特点越来越多样化，其持续性能不仅强烈地依赖于系统的峰值浮点运算性能，还依赖于其存储器带宽。NEC的目标是提供上级持续性能，特别是对于内存密集型科学应用。作为SX-9的继任者，其全新的SX-ACE矢量超级计算机就是为了实现这一目标而开发的。新的矢量处理器具有64 Gflop/s的世界顶级单核性能，每核最大内存带宽为64 GB/s。SX-ACE处理器集成了四个内核、内存控制器和一个网络控制器，使处理器性能达到256 Gflop/s，内存带宽为256 GB/s。为了获得更高的持续性能，该系统配备了一个专门的网络互连处理器，以及一个复杂的矢量化编译器和操作系统。
Many of the current supercomputers tend to pursue higher peak performance, however, the characteristics of scientific applications are getting diversified, and their sustained performance strongly depends on not only the peak floating point operation performance of the system, but also its memory bandwidth. NEC’s goal is to provide superior sustained performance, especially for memory-intensive scientific applications. As the successor to the SX-9, its brand-new SX-ACE vector supercomputer has been developed to achieve this goal. The new vector processor features the world top-class single core performance of 64Gflop/s with the largest memory bandwidth of 64GB/s per core. Four cores, memory controllers, and a network controller are integrated into the SX-ACE processor, enabling the processor performance of 256Gflop/s with its memory bandwidth of 256GB/s. In order to gain a higher sustained performance, the system is equipped with a specialized network interconnecting processors, as well as a sophisticated vectorization compiler and an operating system.
