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

这是一项关于启动一个协调的国际艾级计算软件计划的建议。这将采取一系列的三个研讨会的形式，以吸引适当的国家和国际合作伙伴，制定路线图，并制定一个积极的计划，以确保软件的规划，预算，并希望及时开发的艾级计算的到来。该项目得到了能源部以及欧洲联盟和日本的国际合作伙伴的大力支持。正在请求NSF的支持，以帮助招募NSF社区作为该计划的创始合作伙伴。该项目在我们仍在研究Petascale的时候启动，非常及时地满足了“其目标需求的重要性和紧迫性，为未来几代非常高性能计算软件奠定了基础并启动了实施。“软件差距--在最新的体系结构上使用的有效软件只有在计算机可用的几年后才能使用--困扰着从千兆级到千兆级的每一代新的高性能计算机。为艾级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引人注目，并且如果没有这种类型的协调和预先投资，可能会使许多艾级投资几乎没有用处。

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.
