The investigators propose to participate in organizing the next ICOSAHOM (International Conference on Spectral And High-Order Methods) on June 22-26 2009 at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. They have been working in this field for several decades and have been active participants in all past ICOSAHOM meetings. Selected papers from the proceedings will be published as a special issue in a archival journal. They also plan to produce a report for the funding agency that will provide feedback from a round-table discussion we plan to organize. The theme of this round-table discussion will be the future algorithmic trends and applications of numerical methods and what is the role of high-order methods. Also, their transition to computer codes that will be used for the simulation needs of the national labs and in industry will be discussed, especially in the context of petaflop applications. To this end, they plan to invite researchers with advanced computing expertise and also have interest on high-order accuracy to participate in this panel. The invited and contributed talks will contain new theoretical and applications results of spectral and high-order methods which had not been published yet. Spectral and high-order methods have become increasingly important in diverse applications as aeroacoustics, electromagnetics, ocean modeling, seismology, energy, non-Newtonian flows, nonlinear optics, plasma dynamics, and uncertainty quantification. New developments in the last few years have addressed issues of complex geometry, high-speed flows, fast solvers for large-scale simulations, reduced order modeling, and stochastic modeling.NSF has invested heavily in computer hardware in their last three decades in par with the rapid growth of computer industry. However, simultaneous advances are required in the development of algorithms and software in order to make effective use of the new computer resources. This conference will advance the state-of-the-art in algorithms of high accuracy that are required in order to produce credible simulation results. In addition to the senior researchers invited, we plan to sponsor young researchers, postdocs and PhD students, especially from under-represented minorities, in order to educate a new cadre of simulation scientists in these methods. Today, high-order accuracy (at least second-order) is a requirement for publishing archival work in engineering journals, and the planned panel discussion is expected to have great impact in the engineering community. In addition, the important issue of numerical versus modeling accuracy and issues related to Verification and Validation will be discussed.

研究人员建议于2009年6月22日至26日在挪威特隆德海姆的挪威科学技术大学（NTNU）举行下一次Icosahom（国际光谱和高级方法国际会议）。他们在这个领域工作了几十年，并且在过去的所有Icosahom会议上都积极参与。诉讼中的精选论文将在档案期刊上发表。他们还计划为资助机构提供一份报告，该报告将提供我们计划组织的圆桌讨论中的反馈。这个圆桌讨论的主题将是未来的算法趋势和数值方法的应用以及高级方法的作用是什么。此外，将讨论将用于国家实验室和行业的模拟需求的计算机代码的过渡，尤其是在Petaflop应用程序的背景下。为此，他们计划邀请具有高级计算专业知识的研究人员，并且对高阶准确度有兴趣参加该小组。受邀的和贡献的谈判将包含尚未发布的光谱和高级方法的新理论和应用结果。光谱和高级方法在各种应用中变得越来越重要，例如航空声学，电磁，海洋建模，地震学，能量，非牛顿流，非线性光学，等离子体动力学和不确定性量化。在过去的几年中，新的发展已经解决了复杂的几何形状，高速流动，大规模模拟的快速求解器，减少订单建模和随机建模的问题。NSF在过去的三十年中，与计算机行业的快速增长相同，在计算机硬件中大量投资了计算机硬件。但是，在开发算法和软件中需要同时进步，以便有效利用新的计算机资源。为了产生可靠的仿真结果，这次会议将推进所需的高精度算法的最新算法。除了邀请的高级研究人员外，我们还计划赞助年轻的研究人员，博士后和博士生，尤其是来自代表性不足的少数民族的学生，以教育新的模拟科学家干部。如今，高阶精度（至少二阶）是在工程期刊上发布档案工作的要求，预计计划的小组讨论将对工程社区产生重大影响。此外，将讨论数值与建模准确性与验证和验证有关的问题的重要问题。
