A group of applied mathematicians in the Department of Mathematics atthe University at Buffalo proposes to purchase a distributed-shared memory multiprocessor cluster,workstations, and supplementary software. The new equipment will be used to support ongoing mathematical research projects in modeling and simulations. These research projects include the study of nonlinear and stochastic effects in fiber optics systems, analysis of coupling and uncertainty in renal hemodynamics, and an investigation of the dynamics and ill-posedness in models of crystalline surfaces especially under conditions of strong anisotropy. These projects share several features. Becauses of the interdisciplinary collaboration of each project, the co-investigators require a computing environment that allows them to rapidly develop initial model systems, usually systems of partial or ordinary differential equations, and explore solutions to these equations without extensive coding. As a model matures, the governing equations may then be solved by moderate-sized numerical simulations. Efficient numerical simulation of these dynamic models requires a computing infrastructure with large memory capacity and high bandwidth. Again because of the interdisciplinary nature of the research projects under study, parameter exploration and model validation require significant computational effort. Moreover, stochastic effects can play an important role in the model dynamics, adding to the computing burden. Comparison of model results with experiments, and communication of these results, is facilitated by advanced visualization software. The cluster to be purchased will serve these requirements, and will significantly enhance the co-investigators? research capabilities.A group of applied mathematicians in the Department of Mathematics at the University at Buffalo proposes to purchase a distributed-shared memory multiprocessor cluster, workstations, and supplementary software. The new equipment will be used to support ongoing modeling and simulation research in fields of engineering and bio-medical application that are computationally intensive. Because the co-investigators work in highly interdisciplinary fields of study, the mathematical research advances made in these projects quickly impact fields of applied science. The cross-disciplinary nature of the co-investigators provides a stimulating environment for the training of graduate students. The co-investigators also provide opportunities for undergraduates to experience research in mathematics. The proposed equipment will benefit these students - the graduate students in their research careers, and the undergraduate students as they leave the university for graduate study or enter the workforce.

布法罗大学数学系的一组应用数学家建议购买分布式共享的内存多处理器群集，工作站和补充软件。新设备将用于支持建模和仿真中正在进行的数学研究项目。这些研究项目包括对光纤系统中非线性和随机效应的研究，肾脏血流动力学的耦合和不确定性的分析，以及对晶体表面模型中的动力学和不良性的研究，尤其是在较强的各向异性条件下。这些项目具有多个功能。由于每个项目的跨学科协作，共同投资者需要一个计算环境，使他们能够快速开发初始模型系统，通常是部分或普通微分方程的系统，并探索对于这些方程的解决方案而无需进行广泛编码。随着模型的成熟，可以通过中等尺寸的数值模拟来解决管理方程。这些动态模型的有效数值模拟需要具有较大记忆力和高带宽的计算基础架构。再次由于研究项目的跨学科性质，参数探索和模型验证需要大量的计算工作。此外，随机效应在模型动力学中可以发挥重要作用，从而增加了计算负担。通过高级可视化软件促进了模型结果与实验的比较以及这些结果的通信。购买的集群将满足这些要求，并会大大增强共同投资者？研究能力。布法罗大学数学系的一组应用数学家组建议购买分布式共享的内存多处理器群集，工作站和补充软件。新设备将用于支持计算密集型的工程和生物医学应用领域的持续建模和仿真研究。由于共同投资者在高度跨学科的研究领域工作，因此这些项目中的数学研究进展很快影响了应用科学的领域。共同投资者的跨学科性质为研究生的培训提供了一个刺激的环境。共同投资者还为大学生​​提供了体验数学研究的机会。拟议的设备将使这些学生受益 - 研究职业的研究生以及本科生离开大学进行研究生学习或进入劳动力。
