Extending the Work of the International Exascale Software Project

国际亿级软件项目(IESP)聚集了来自全球高性能计算(HPC)社区主要领域的代表--软件研发、尖端科学应用、领先水平的设施、主要系统供应商和相关的政府资助机构--积极努力为代表计算科学未来的极端规模系统规划和创建新的软件基础设施。通过2009年春季开始的一系列研讨会，IESP及其国际合作伙伴在美国、欧洲和亚洲之间轮流举办了一系列研讨会，努力在制定具有亿级能力的软件基础设施的长期路线图以及启动生产该路线图所需的相应研究和开发过程方面发挥领导作用。如IESP路线图1.0版(以下称为“路线图”，于2010年5月30日出版)所述，该项目的使命致力于科学计算的未来愿景，包括两个关键目标：IESP的指导目标是通过制定一个计划，在2020年前增强超高分辨率和数据密集型科学和工程研究的能力，1)为Peta/艾斯卡系统开发一个通用的、高质量的计算环境；2)催化、协调和持续国际开源软件界为尽快创建该环境所做的努力。(路线图，第3页)在美国、欧洲和亚洲之间轮流举办的一系列研讨会上，来自高性能计算社区所有阶层的IESP参与者已经开始就一项计划达成工作共识，该计划旨在应对为极端规模计算科学创建软件堆栈的重大挑战，我们称之为“X堆栈”。在这一成功的基础上，我们提议于2012年春季在芝加哥举行的IESP研讨会将专注于进一步开发和扩大计划中确定的战略，以便在实现项目目标的过程中取得更快的进展。

The International Exascale Software Project (IESP) brings together representatives from the major segments of the global high performance computing (HPC) community -- software research and development, leading edge scientific applications, leadership-class facilities, major system vendors and relevant government funding agencies -- in a proactive effort to plan and create a new software infrastructure for the extreme scale systems that represent the future of computational science. Through a series of workshops, begun in the spring of 2009 and rotating between the US, Europe, and Asia, the IESP and its international partners have endeavored to provide leadership in formulatung a long-term roadmap to an exascale-capable software infrastructure, and in initializing the corresponding research and development process necessary to produce it. As expressed in the IESP Roadmap version 1.0 (referenced below as "Roadmap" and published on May 30, 2010), the project's mission commits to a vision of the future of scientific computing that involves to two key objectives: The guiding purpose of the IESP is to empower ultrahigh resolution and data intensive science and engineering research through the year 2020 by developing a plan for 1) a common, high quality computational environment for peta/exascale systems and for 2) catalyzing, coordinating, and sustaining the effort of the international open source software community to create that environment as quickly as possible. (Roadmap, p. 3)In a series of workshops, rotating between the United States, Europe and Asia, IESP participants from all segments of the HPC community have begun to forge a working consensus on a plan to address the momentous challenge of creating a software stack for extreme-scale Computational Science, which we call an "X-stack." Building on this success, our proposed IESP workshop for the spring of 2012 in Chicago will focus on further developing and expanding upon the strategies identified in the plan in order to make more rapid progress toward the project's objectives.
