Predictive dynamic system scheduling

摘要

Resources of a partitionable computer system are partitioned into at least first and second partitions, in accordance with a first or second mode of operation of the partitionable computer system. The system is run in the first or second mode, partitioned in accordance with the partitioning step. Periodically, it is determined whether the computer system should be switched from one mode to the other mode. If so, the computer system is run in the other mode, partitioned in accordance with the other mode. The first and second modes of operation are defined in accordance with historical observations of the partitionable computer system. The periodic determination is carried out based on predictions in accordance with the historical observations.

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.
