Programming Models and Application Requirements for an Exascale Computing Point Design Study

NSF和其他联邦机构在制定未来的使能技术、体系结构和方法计划之前，将需要进一步了解亿级计算系统的概念、方法和手段。这样的理解将推动在实现亿级系统的过程中确定未知因素、应对挑战、指导战略和执行任务。到2018年实现能够持续计算Exaflop的系统的目标建议，致力于这一目标的受赞助的研发计划不迟于2011年开始，以提供足够的时间来完成必要的研究、设计和实施任务。NSF针对亿级计算的点设计研究是三项任务的集合，这些任务将由这些领域的专家研究三种不同的计算制度。虽然每个国家都是独立的，但它们将从合作和成果分享中受益匪浅，每个国家都受到从其他国家获得的见解的指导。这些是1)应用程序和编程模型，2)系统架构和操作系统，以及3)硬件技术和组件设计。本SGER将学习亿级计算的点设计研究的应用程序和编程模型方面。

NSF and other Federal agencies will require further understanding of concepts, methods, and means for Exascale computing systems before formulation of future programs in enabling technologies, architectures, and methodologies. Such understanding will drive the unknowns to be determined, the challenges to be addressed, strategies to guide, and tasks to be performed on the way to Exascale system realization. The objective of realizing systems capable of sustained Exaflops computing by 2018 suggests that sponsored R&D programs dedicated to this goal be started no later than 2011 to provide sufficient time to complete the ensemble of necessary research, design, and implementation tasks. The NSF Point Design Study for Exascale Computing is a collection of three tasks that will look at three different regimes of computing by experts in those areas. While each is stand alone, they will benefit strongly through cooperation and sharing of results, each being guided by the insights derived from the others. These are 1) applications and programming models, 2) system architecture and operating systems, and 3) hardware technology and component design. This SGER will study applications and programming models aspect of the Point Design Study for Exascale Computing.
