摘要:

虽然HPC社区正在努力开发第一台Exaflop计算机(预计在2020年左右),但在2008年达到Petaflop里程碑后,仍然只有少数HPC应用能够充分利用Petaflop系统的功能。在本文中,我们认为,准备HPC应用程序的Exascale的努力应该开始之前,这样的系统变得可用。我们确定需要解决的挑战,并在关键领域推荐解决方案,包括正式建模,静态分析和优化,运行时分析和优化,以及自主计算。此外,我们概述了一个概念框架,用于将HPC应用程序移植到未来的Exascale计算系统,并提出了实施步骤。

英文摘要:

While the HPC community is working towards the development of the first Exaflop computer (expected around 2020), after reaching the Petaflop milestone in 2008 still only few HPC applications are able to fully exploit the capabilities of Petaflop systems. In this paper we argue that efforts for preparing HPC applications for Exascale should start before such systems become available. We identify challenges that need to be addressed and recommend solutions in key areas of interest, including formal modeling, static analysis and optimization, runtime analysis and optimization, and autonomic computing. Furthermore, we outline a conceptual framework for porting HPC applications to future Exascale computing systems and propose steps for its implementation.
