Mathematical Sciences Computing Research Environments

杜克大学数学系将购买一台高端可视化机器，该机器具有充足的内存、快速通信卡、视频设备和磁盘驱动器，将专门用于支持数学科学的研究。该设备将用于多个研究项目，包括表面活性剂强化含水层修复模拟、多接触面混相注气提高采收率模拟、多孔介质三相流动孔隙尺度模拟网络模型、颗粒材料剪切带形成和生长模拟。计算将涉及通过高分辨率有限差分方法、自适应网格细化、前沿跟踪和分子动力学来定位计算工作的复杂技术。由于计算量大，需要大量的计算机内存（RAM和磁盘），以及与超级计算机的快速通信。

9508325 Trangenstein The Department of Mathematics at Duke University will purchase a high end visualization machine with ample memory, fast communications card, video equipment and disk drives that will be dedicated to the support of research in the mathematical sciences. The equipment will be used for several research projects, including the simulation of surfactant enhanced aquifer remediation, multiple contact miscible gas injection for enhanced oil recovery, network models for pore scale modeling in three-phase flow in porous media and shear band formation and growth in granular materials. The calculations will involve sophisticated techniques for localizing the computational effort via high-resolution finite difference methods, adaptive mesh refinement, front tracking and molecular dynamics. Because of the large size of the computations, a large amount of computer memory is needed (both RAM and disk), and fast communications with supercomputers.
