Collaborative Proposal: The IESP: Planning to create next generation software infrastructure for exascale science

这是一项提议，旨在启动一个关于百亿亿次计算软件的国际协调项目。这将采取一系列的三个研讨会的形式，让适当的国家和国际合作伙伴参与进来，制定路线图，并制定一个积极的计划，以确保软件的计划、预算和希望及时开发，以迎接百亿亿次计算的到来。该项目得到了美国能源部以及欧盟和日本等国际合作伙伴的大力支持。正在请求国家科学基金会的支持，以帮助招募国家科学基金会社区作为该计划的创始合作伙伴。这个项目是在我们还在处理Petascale的时候开始的，“它的目标是为高性能计算奠定基础并开始实施未来几代软件的重要性和紧迫性”，因此非常及时。从千兆级到千兆级的每一代新型高性能计算机，都面临着软件缺口的困扰——在最新架构上使用的高效软件要在计算机问世数年后才可用。为百亿亿次所设想的截然不同的计算机体系结构可能会使这种差距更加明显，并且如果没有这种类型的协调和先进的软件投资，可能会使许多百亿亿次投资几乎没有用处。

This is a proposal to launch a coordinated international program on software for exascale computing. This will take the form of a series of three workshops to engage the appropriate national and international partners, develop the roadmap and create an aggressive plan for making sure the software is planned, budgeted and hopefully developed in time for the arrival of exascale computing. The project has deep support from the Department of Energy and international partners in the European Union and Japan. The support of NSF is being requested to help recruit the NSF community as founding partners in the program. The project, being started at a time when we are still coming to grips with Petascale, is very timely in "the importance and urgency of the need it targets laying the foundations and initiating the implementation of future generations of software for very high performance computing." The software gap -- whereby efficient software to use on the latest architecture is only available years after the computer is available has bedevilled every generation of new high performance computers from the gigascale to the petascale. The dramatically different computer architectures that are envisioned for the exascale is likely to make this gap even more dramatic and perhaps render much of the exascale investments of little use without this type of coordianted and advance investment in the software.
