NEC Vector Supercomputer: Its Present and Future

  • Shintaro MomoseEmail author


SX-ACE launched in 2014 is a successor model of the SX-9 vector parallel computer, which pursues a much higher sustained performance particularly in memory-intensive scientific applications. The major concept of SX-ACE is the provision of a world top-level single core performance of 64 GFlop/s, as well as the world largest memory bandwidth per single core of 256 GB/s in its maximum with a high power efficiency. It is also designed to make available a user-friendly environment that can be combined with PC clusters in targeting a wide range of application areas. Experimental results demonstrate that SX-ACE can provide a much higher sustained performance and a power efficiency compared with modern supercomputers especially for memory-intensive applications. Moreover, NEC has a plan to release a follow-on system of SX-ACE. The new system is aimed at incorporating standard features and use environments of PC clusters while maintaining a high sustained performance realized with SX-ACE. It is expected to cover more extensive market areas, including emerging big data analyses, as well as conventional scientific and engineering applications.
