In the past year the facility* has been upgraded in order to meet our increasing computational and visualization needs. We have expanded our graphics power and capabilities with the addition of a) an HP c200 workstation with fx4 high-performance, stereo-capable 3D graphics and b) an SGI Onyx2 InfiniteReality Rack with eight 195 Mhz R10000 parallel processors sharing one gigabyte of RAM. The SGI Onyx2 InfiniteReality Rack is our top-end high-performance graphics and computing machine, equipped with eight 195 Mhz R10000 parallel processors sharing one gigabyte of RAM. The Onyx2 drives the 3-D visualization facility and has been integrated into the group's current ATM system and connected to the pre-existing cluster of workstations. With the acquisition of the Onyx2, which also serves as one of our main computational platforms, our overall computational power has increased substantially. At the same time we also upgraded our four existing HP K9000 four processor machines from 128MB of memory to 256 MB of memory per-processor. A recently ordered SGI Origin200 server with 4 180 MHz processors and 512MB of RAM will be installed by the end of May. By late summer we are planning to install a Beowulf cluster consisting of eight dual-processor nodes running the Linux operating system and connected via switched 100Mb fast Ethernet. Each node will contain two 400MHz Pentium II processors sharing a 100MHz memory bus to 256MB. Later in the year, the cluster will be upgraded from 8 to 16 nodes. This Beowulf cluster will be a primary target platform for NAMD development as well as for simulation jobs. This year, as in previous years, the group has been awarded a National Resource Allocations Committee (NRAC) award for computer time at the National Science Foundation funded supercomputer centers. We have been awarded 45,000 service units on NCSA's Origin2000, 100,000 service units on NCSA's Convex Exemplar, and 20,000 Units on PSC's T3E.

在过去的一年里，该设施*进行了升级，以满足 我们日益增长的计算和可视化需求。我们有 通过添加)扩展了我们的图形能力和功能 配备FX4高性能、支持立体声功能的3D的HP C200工作站 显卡和b)8个195 MHz的SGI Onyx2 InfiniteReality机架 R10000并行处理器共享1G的RAM。SGI Onyx2 InfiniteReality Rack是我们的高端高性能显卡和 计算器，配备八台195兆赫R10000并行 共享1G内存的处理器。Onyx2驱动3-D 可视化设施，并已整合到集团的 当前ATM系统，并连接到预先存在的群集 工作站。收购了Onyx2，这也是 我们的主要计算平台之一，我们的整体计算 电力已大幅增加。与此同时，我们也进行了升级 我们现有的四台HP K9000四处理器计算机 内存到每个处理器256 MB内存。最近订购的SGI 配备4个180 MHz处理器和512MB RAM的Origin200服务器将 将于5月底安装完毕。我们计划在夏末之前安装 由8个双处理器节点组成的Beowulf集群，运行 Linux操作系统，通过交换式100Mb快速以太网连接。 每个节点将包含两个400 MHz奔腾II处理器，共享一个 100 MHz内存总线至256MB。今年晚些时候，该集群将 从8个节点升级到16个节点。该Beowulf集群将成为主要的 NAMD开发以及模拟作业的目标平台。 今年，和往年一样，该组织被授予国家 资源分配委员会(NRAC)颁发的计算机时间奖 国家科学基金会资助超级计算机中心。我们有 在NCSA的Origin2000,100,000上获得了45,000个服务单位 NCSA凸样本上的服务单位，以及PSC上的20,000个单位 T3E。
