AUTONOMOUS DYNAMIC OPTIMIZATION OF PLATFORM RESOURCES

摘要

Methods for dynamically optimizing platform resource allocation of a logically-partitioned data processing system. Processor and memory resources are allocated to logical partitions of the data processing system. After allocating the processor and memory resources to the plurality of logical partitions, local and non-local memory accesses are monitored for the logical partitions. Based at least in part on the local and non-local memory accesses, a determination is made whether to reallocate the processor and memory resources of the logical partitions. Responsive to determining to reallocate the processor and memory resources, the processor and memory resources are dynamically reallocated to the logical partitions of the data processing system.

1. A logically-partitioned data processing system comprising:
a plurality of processors; at least one memory, wherein processor resources of the plurality of processors and memory resources of the at least one memory are allocated to a plurality of logical partitions; and program code configured to:
after the processor and memory resources are allocated to the plurality of logical partitions in the logically-partitioned data processing system, monitor local memory accesses by the plurality of logical partitions and monitor non-local memory accesses by the plurality of logical partitions;determine whether to reallocate the processor and memory resources for the plurality of logical partitions based at least in part on the monitored local memory accesses and monitored non-local memory accesses; andin response to determining to reallocate the processor and memory resources for the plurality of logical partitions, dynamically reallocate the processor and memory resources to the plurality of logical partitions in the logically-partitioned data processing system.
