Algorithms: A Toolbox of Scalable Algorithms and Software for Advanced Scientific Computing Applications

这项拟议工作的目的是开发新的可扩展算法和软件，以解决科学计算应用中出现的一些突出问题。特别是，需要多尺度或多物理模型解决方案的计算复杂的模拟将受益。这项研究的一个重要组成部分将是与考虑这种性质的问题的应用科学家的合作。PI项目在为非结构化网格计算中固有的基本问题开发可伸缩算法方面具有丰富的经验和成功。该工具包的实现将成为使教育工作者和科学家能够更好地利用大规模计算基础设施的重要资源。这项拟议的工作是通过私人投资机构与其他NSF资助的大学倡议、国家实验室正在进行的工作以及与工业界的显著合作来推动的。这些协作将促进工具包的广泛使用以及反馈，以确保开发的工具包与用户需求相关。该工具包将通过直接合作传播到公共领域，以确保广泛使用。

The aim of this proposed work is the development of new scalable algorithms and software toaddress a number of outstanding problems arising in scientific computing applications. In particular,computationally complex simulations that demand the solution of multi-scale or multi-physics models will benefit. A significant component of this research will be the collaboration with applications scientists considering problems of this nature.The project PIs have had significant experience and success in the development of scalablealgorithms for the fundamental problems inherent in unstructured mesh calculations.The realization of this toolkit will be a significant resource enabling educators and scientiststo make better use of the large-scale computing infrastructure. This proposed work is driven through signi.cant collaborations by the PIs with other NSF-funded initiatives at Universities,on-going work at the National Laboratories,and with Industry. These collaborations will promote widespread use of the toolkit as well as feedback to ensure that the toolkit developed is relevant to user needs. The toolkit will be disseminated into the public domain, as well as through direct collaboration, to ensure widespread use.
