2011年12月30日国际讲座
讲座题目：Frontiers of Volunteer Computing
报告人：David P. Anderson教授
时间：2011年12月30日上午10:00---11:30
地点：清华大学航天航空学院1512室
摘要：Volunteer computing is the most powerful form of scientific distributed computing, exceeding Grids and Clouds in terms of number of nodes and computational throughput. BOINC is a widely-used middleware system for volunteer computing. I will discuss several areas of research and development in BOINC.
- The use of virtual machine technology:
BOINC now supports applications that run in virtual machines, using VirtualBox. This reduces heterogeneity-related complexity, and it makes it feasible to use untrusted applications in volunteer computing projects.
- Volunteer storage:
Volunteered hosts are able to provide significant storage as well computing power. I will describe various ways in which this storage can be used, and will discuss the problem of using a rapidly-changing host population to provide high-reliability storage.
- Multi-user projects:
Early volunteer computing projects served a single research group and supported throughput-oriented computing. More recently, many projects serve a large and dynamic set of users (i.e. job submitters), and must support latency-oriented handling of batches of jobs. This requires a set of related policies involving quotas, fairness, and scheduling.
简介：Anderson教授在分布式志愿计算领域的研究一直处于世界领先地位。他的研究兴趣包括分布式系统、操作系统、多媒体系统、电脑绘图和电脑音乐等方面。1998年以来，他指导志愿计算的先驱项目SETI@home，吸引了一百多万的志愿者参与其中。Anderson教授还担任BOINC项目的领导人。BOINC项目是为志愿计算开发可以广泛应用的中介平台，现在约有50多个属于不同科学领域的项目在这个平台上运作。Anderson教授还从事分布式思考技术的研究和大型网络培训和教育技术的研究。Anderson教授在威斯康星大学麦迪逊分校获得数学硕士和计算机科学博士学位。1985年-1992年，他在美国加州大学伯克利分校的计算机系工作，并且是休斯顿大学计算机系的兼职教授。 |
