Workshop on Petascale Computing and the Geosciences

这是一项规划活动，旨在发展对地球科学研究界为利用美国国家科学基金会的战略计划为科学和工程开发千万亿级计算环境所需要的活动的理解。它将把来自计算机科学、空间物理学、海洋科学、大气科学和地球科学的参与者聚集在一个小型研讨会上，旨在启动开发下一代地球科学研究代码的过程，这些代码在千万亿次系统上表现良好。长期目标是让地球科学家在部署千万亿级系统时能够更好地进行前沿研究。第一次研讨会将评估当前地球科学高端计算模型的代表性样本的可行性，分析现有算法的性能和结构，并描述地球科学家希望用千万亿次资源解决的问题。适当的专家将介绍有关性能度量和代码特性、性能建模和程序开发的新方法和工具的信息。预期的结果将是确定一些早期合作或试点研究的想法，旨在使用这些现代工具来研究和改进重要的地球科学研究应用。这些合作将在第一次讲习班后的大约六个月内继续进行。将在第二次讲习班上报告结果和吸取的教训。将编写一份公开可用的流程报告，预计这将有助于更广泛的社区规划为千万亿次计算系统的使用准备计算地球科学所需的步骤。预计这一活动将为地球科学建模能力的未来发展提供种子，其应用范围将超越地球科学研究，扩展到使用地球科学计算代码的其他领域，如天气和季节性气候预报、沿海洪水模拟、地震灾害和空间天气。

This is a planning activity designed to develop understanding of the activities needed to prepare the geoscience research community to exploit NSF's strategic plan to develop a petascale computing environment for science and engineering. It will bring together participants from computer science, space physics, ocean science, atmospheric science, and Earth science in a pair of small workshops intended to jump-start the process of developing next-generation geoscience research codes that perform well on petascale systems. The long-term intent is to better position geoscientists to be able to conduct cutting-edge research with petascale systems when these are deployed. The first workshop will assess the viability of a representative sample of current, geoscience, high-end, computational models, analyze the performance and structure of existing algorithms, and characterize the problems that geoscientists wish to tackle with petascale resources. Appropriate experts will present information about new approaches and tools for performance measurement and code characterization, performance modeling, and program development. An intended outcome will be the identification of some ideas for early collaborations or pilot studies aimed at using some of these modern tools to study and improve significant geoscience research applications. These collaborations will be pursued for roughly six months after the first workshop. Results and lessons learned will be reported at the second workshop. A publicly available report of the process will be written and it is anticipated that this will help the broader community plan the steps needed to prepare computational geoscience for the use of petascale computing systems. It is anticipated that this activity will seed future advances in the capabilities of geoscience modeling, with applications beyond geoscience research to other areas in which geoscience computational codes are used, such as weather and seasonal climate forecasting, coastal inundation simulation, earthquake hazards, and space weather.
