摘要/Abstract

摘要：

高性能计算技术以加速度迅猛发展，继千万亿次系统研制成功以后，超级计算机的性能又快速提升至数万万亿次，国际学术界与工业界普遍预期在2018年左右将出现极大规模并行的百万万亿次系统（Exascale Computing，简称E级系统）。本文从最新一届TOP500榜单入手分析了超级计算领域的技术动态，在此基础上，探讨了未来E级系统的发展趋势及其所面临的能耗、可扩展、可靠性和可编程性等关键技术问题。

关键词: E级计算, 能耗, 可扩展, 可靠性, 可编程性

Abstract:

High performance computing technology developed as an accelerating speed,after the emerging of the Petaflops systems,the performance of supercomputers already increased rapidly to tens Petaflops in very short term.The general prospect by international academe and industry is that the Exascale computing system will emerge around year 2018. This paper will analyses the trend of supercomputing development based on the 39th TOP500 list, and furthermore, discuss the future Exascale computing trend and related key issues,including power consumption, scalability, reliability and programmability, etc.

Key words: exascale computing；power consumption；scalability;reliability；programmability
