1. A method comprising: defining first and second modes of operation of a partitionable computer system based on historical observations of resource usage and execution times of jobs and a degree of user activity required to execute the jobs of said partitionable computer system; partitioning resources of the partitionable computer system into at least first and second partitions for the defined first mode of operation and partitioning resources of the partitionable computer system into at least first and second partitions for the defined second mode of operation, wherein the first and second partitions of the defined first mode of operation are different from the first and second partitions of the defined second mode of operation; running said partitionable computer system, in said one of said defined first and second modes of operation, partitioned in accordance with said partitioning step; periodically determining whether said computer system should be switched from said one of said defined first and second modes of operation to another of said defined first and second modes of operation, said periodic determination being carried out based on predictions in accordance with said historical observations; and responsive to said periodic determination being affirmative, running said computer system, in said another of said defined first and second modes of operation, partitioned in accordance with said another of said defined first and second modes of operation.
