利用结构化对等网络构造计算资源共享平台

Building computing resource sharing platform using structured P2P approach

设计和构建了一个基于结构化对等网络的计算资源共享平台DHT-CRSP。它可以把因特网上用户提交的科学计算作业高效地映射到平台中合适的工作节点上运行,通过容错和安全机制,能保证系统的可靠性和正确性。描述了DHT-CRSP中支持的两种分布式哈希表:Chord协议节点树和CAN协议空间区域;分析了DHT-CRSP中高效的资源匹配算法。通过构建评测环境,运行各种负载与作业场景下的结果表明,DHT-CRSP系统可以获得好的负载均衡性能、低的资源匹配代价,它提供了一种构建高性能的桌面网格平台的新思路。

This paper designed and built a distributed hash table based computing resource sharing platform named DHT- CRSP. By employing P2P services, DHT-CRSP allowed users to submit jobs to be run in the system and to run jobs submitted by other users on any resources available over the Internet, essentially allowing a group of users to form an Ad hoc set of shared resources. Also described the fault-tolerance and security mechanism subsequently and achieved thus the high reliability and correctness. And concentrated on developing matchmaking algorithms for a decentralized and heterogeneous environment, the Chord and CAN. The experimental results obtained via simulations show that the system can reliably execute scientific applica- tions on a widely distributed set of resources with good load balancing and low matchmaking cost.
