- Abstract
- Cluster systems with high price-to-performance ratio have been utilized in various fields and size of cluster systems is increasing rapidly. Also, as the information retrieval and sharing through the internet are used widely, scale of portal sites that collect, process and provide information, become larger. These portal sites have large scale cluster system to serve mass information, and operation and maintenance of the large cluster system Is a big challenge to the portal sites. Because power cost is one of the main issues in the maintenance of the large cluster system, It is necessary to reduce the power cost of the cluster system. As one solution for this problem, this paper presents the CPU power management mechanism that reduces power usage of the cluster system.
