Partial support is provided for the acquisition of a scientific computing system for the Wake Forest University Physics and Chemistry departments. The primary use of this facility would be to support the departments' research in theoretical condensed matter physics, quantum chemistry, and quantum field theory in curved space. At present these departments operate a system consisting of two Convex C-120 vectorizing minisupercomputers. The proposed new system will replace these obsolete computers with a cluster of the latest RISC superscalar processors. The problems to be studied include: 1) density functional investigation of surface reconstruction and of electron tunneling; 2) nonlinear effects in the dynamics of structural phase transitions; 3) point defect structures in solids; 4) effects of quantum fields on black hole spacetimes; and 5) quantum chemical investigation of atmospheric molecular species. The computer configuration to be purchased is a cluster of Hewlett-Packard workstations, configured into a Meta-system by Convex. The system consists of the following hardware: four HP 9000/735 computational nodes each with 128 Megabytes of memory and a 1 Gigabyte internal disk; 20 Gigabyte of external disk storage; an additional HP 9000/735 with smaller memory and disk for system administration. Convex packages the HP workstations into a single unit and provides software that unifies the system operation and includes a library of highly optimized scientific subroutines.

为Wake Forest University物理和化学部门获得科学计算系统提供了部分支持。该设施的主要用途是支持部门在弯曲空间中的理论凝结物理学，量子化学和量子场理论方面的研究。目前，这些部门运行了一个由两个凸C-1220矢量化minisupercuputer组成的系统。提出的新系统将用最新的RISC SuperScalar处理器群替换这些过时的计算机。要研究的问题包括：1）表面重建和电子隧穿的密度功能研究； 2）在结构相变动力学中的非线性效应； 3）固体中的点缺陷结构； 4）量子场对黑洞空位的影响； 5）大气分子物种的量子化学研究。要购买的计算机配置是由凸面配置为元系统的惠普工作站集群。该系统由以下硬件组成：四个HP 9000/735计算节点每个都有128兆字节的内存和1千兆字节的内部磁盘； 20千兆字节的外部磁盘存储；额外的HP 9000/735，具有较小的存储器和用于系统管理的磁盘。 将HP工作站的凸面包装到一个单元中，并提供统一系统操作的软件，并包括高度优化的科学子例程的库。
