Instrumentation Grant for Research in Parallel and Distributed Computing

美国佐治亚大学并行与分布式计算研究仪器资助佐治亚大学并行与分布式计算实验室成立于1998年，致力于使并行计算简单、便携和高效。实验室的活动包括设计和实现高效的并行算法，为分布式程序的监控、可视化和交互式指导开发高度可配置的环境，以及开发透明和动态地决定如何跨处理器分发数据的低级系统。目前实验室的研究主要集中在商用单处理机工作站的网络上。小型、基于总线的多处理器相对于单处理器具有吸引力的性价比，这使得两路和四路多处理器很可能在几年内普及。然而，为了创建大型并行机器，这些多处理器将联网在一起，以创建混合（共享和分布式内存）机器。这带来了一些有趣的问题，包括(1)应该将机器视为分布式的，还是既是共享的又是分布式的。(2)我们如何充分利用这些机器？(3)用户如何监控这些机器上的程序？佐治亚大学计算机科学系正在寻求资金购买8个基于奔腾的多处理器，每个处理器有4个处理器。一个100Mb/s的以太网和一个前端的SGI作为可视化和交互式控制的控制台。该设备将用于三个项目。用于计算生物学的并行和分布式算法监测、可视化和交互式指导，用于全局数据分发的集成编译/运行时系统

EIA-9986032David K. LowenthalUniversity of GeorgiaInstrumentation Grant for Research in Parallel and Distributed ComputingThe Parallel and Distributed Computing Laboratory at the University of Georgia, established in 1998 is dedicated to making parallel computing simple, portable, and efficient. The activities of the laboratory include designing and implementing efficient parallel algorithms, developing highly configurable environments for the monitoring, visualization, and interactive steering of distributed programs, and developing lower-level systems that transparently and dynamically determine how to distribute data across processors. Currently research in the laboratory is primarily done on networks of commodity uniprocessor workstations. The attractive price/performance ration of small, bus-based multiprocessors relative to uniprocessors makes it likely that two-and four-way multiprocessors will be commonplace within a few years. Still, to create large parallel machines, these multiprocessors will be networked together to create a hybrid (both shared-and distributed-memory) machine. This poses interesting problems, including (1) should the machine be treated as distributed or both shared and distributed. (2) How do we make full use of such machines and (3) how can a user monitor and control program on such machines? The Department of computer Science at the University of Georgia seeks funds to purchase eight Pentium-based multiprocessors with four processors each. A 100Mb/s Ethernet and an SGI fronted to serve as a console for visualization and interactive control. This equipment will be used by three projects.Parallel and Distributed algorithms for computational biologyMonitoring, visualization, and interactive steering, andAn integrated compiler/run-time system for global data distribution
