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 扩展了我们的图形处理能力，并增加了a） HP c200工作站，具有fx4高性能、立体3D功能 显卡和B）8个195 MHz的SGI Onyx 2 InfiniteReality机架 R10000并行处理器共享1GB RAM。 SGI Onyx2 InfiniteReality Rack是我们的高端高性能显卡， 计算机，配备8个195 Mhz R10000并行 处理器共享1G的RAM。 Onyx2驱动3D 可视化设施，并已集成到该集团的 当前的ATM系统，并连接到预先存在的 工作站。 随着收购的Onyx 2，这也作为 我们的主要计算平台之一，我们的整体计算平台， 电力大幅增长。 同时我们也升级了 我们现有的四台HP K9000四处理器机器， 内存到每处理器256 MB内存。 最近订购的SGI Origin200服务器配备4个180 MHz处理器和512 MB RAM， 5月底前安装。到夏末，我们计划安装 一个Beowulf集群，由八个双处理器节点组成， Linux操作系统，并通过交换式100 Mb快速以太网连接。 每个节点将包含两个400 MHz Pentium II处理器， 100MHz内存总线到256MB。 今年晚些时候，该集群将 从8个节点升级到16个节点。 此Beowulf群集将是 NAMD开发以及模拟作业目标平台。 今年，与往年一样，该集团已被授予国家 资源分配委员会（NRAC）颁发的计算机时间奖 美国国家科学基金会资助的超级计算机中心。 我们有 在NCSA的Origin2000中获得了45，000个服务单位， NCSA的Convex Exemplar上的服务单位和PSC上的20，000单位 T3E
