This award will allow the Department of Physics at New York Universityto set up a cluster of advanced workstations (48 nodes of dual 866 MHzPentium III processors) to support computationally intensive researchin a number of areas of theoretical physics and astrophysics. Theproposed research projects include:1) properties of atmospheric particle showers induced by ultra-high-energycosmic rays [Farrar];2) simulation of astrophysical magnetic fields [Farrar in collaboration withGoodman and others];3) magnetically controlled electrical transport in layered structures [Levy];4) statistical mechanics of simple and complex fluids [Percus];5) structure formation in the early universe [Scoccimarro and Zaldarriaga];6) asymptotic freedom in two-dimensional $\sigma$-models, and the criticalbehavior of Potts antiferromagnets and of self-avoiding random walk[Sokal];and 7) confinement mechanisms in lattice quantum chromodynamics [Zwanziger].The proposed research making use of this cluster will also providetraining in high-performance scientific computing for the Department'sgraduate and undergraduate students, postdoctoral fellows, and visitingfaculty from other institutions, using a variety of programming languages(Fortran, C, C++, Mathematica) and advanced scientific software. Thistraining in advanced computational techniques will be of benefit byproviding broadly applicable skills, not only to those graduate studentswho pursue subsequent careers in academic research, but also to those whogo on to careers in industrial R+D and elsewhere in society.

该奖项将允许物理系在纽约大学建立一个先进的工作站集群（48个节点的双866兆赫奔腾III处理器），以支持计算密集型研究在理论物理和天体物理学的一些领域。 建议的研究项目包括：1）由超高能宇宙射线引起的大气粒子簇射的性质[Farrar];2）天体物理磁场的模拟[Farrar与Goodman等人合作];3）层状结构中磁控电输运[Levy];4）简单和复杂流体的统计力学[Percus];5）早期宇宙的结构形成[Scoccimarro和Zaldarriaga]; 6）二维$\sigma$-模型中的渐近自由，Potts反铁磁体和自回避随机游动的临界行为[索卡尔];和7）晶格量子色动力学中的限制机制[Zwanziger]。利用这一集群进行的拟议研究还将提供高该中心使用各种编程语言（Fortran、C、C++、Mathematica）和先进的科学软件，为该系的研究生和本科生、博士后研究员以及来自其他机构的访问教师提供高性能科学计算。这种先进的计算技术的训练将有利于提供广泛适用的技能，不仅对那些从事学术研究的研究生，而且对那些从事工业R+D和社会其他领域的研究生。
