Abstract: The invention relates to a computer implemented method for capping the power consumption of a high-performance computer including a plurality of nodes. The plurality of nodes include a first group of nodes of which each node is allocated to a first job, the power capping of each node of the first group of nodes being enforced to a first capping value being dependent on the type of the first job.

Abstract: In this method for controlling a server cluster, the cluster Including a plurality of nodes, automated agents measure the change in at least one metric quantifying the use of the nodes for the execution of an application, the agents determine, for each node, by measuring the metric, whether a change of phase has taken place in the executed application, and cause a change of the operation of the node if necessary; at regular intervals, an automated coordinator aggregates the metric measurements and the changes of operation of the nodes that have taken place and, on the basis of the aggregated measurements, the coordinator sends instructions to at least one of the agents.
