Abstract
Power consumption and computational availability of a cluster are automatically managed by monitoring consumption, predicting demand based on a job queue and/or historic data, and checking certain conditions and constraints. Threshold conditions for switching the cluster's capacity level are based on the current level and the predicted demand. Switching levels is avoided when a stability constraint would be violated. Cluster capacity levels can be uniformly or nonuniformly spaced, and may have decreasing gaps between levels as capacity decreases. Capacity level definitions and level switching conditions and constraints may be defaults and/or be provided by an administrator.
