在本章中，我们将讨论工作站或PC集群的节能问题。我们的方法是开发动态打开集群节点的系统-能够有效地处理施加在系统上的负载-和关闭-在较轻的负载下节省电力。我们的系统的关键组成部分是一个算法，使集群重新配置的决定，通过考虑施加在系统上的总负载和改变当前配置的功率和性能的影响。该算法是在两个常见的基于集群的系统：网络服务器和操作系统的集群循环服务器。我们的实验结果是非常有利的，表明我们的系统节省电力和能源相比，传统的系统。
In this chapter we address power conservation for clusters of workstations or PCs. Our approach is to develop systems that dynamically turn cluster nodes on - to be able to handle the load imposed on the system efficiently - and off - to save power under lighter load. The key component of our systems is an algorithm that makes cluster reconfiguration decisions by considering the total load imposed on the system and the power and performance implications of changing the current configuration. The algorithm is implemented in two common cluster-based systems: a network server and an operating system for clustered cycle servers. Our experimental results are very favorable, showing that our systems conserve both power and energy in comparison to traditional systems.
