Dynamic allocation of CPU resources based on system load trends

摘要

Described are techniques for partitioning processors in a system. At a first point in time, a short term workload ratio and a long term workload ratio are determined. At the first point in time, the system is in a first workload state having a first configuration including a first portion of the processors performing front end processing tasks and a second portion of the processors performing back end processing tasks. A first value is determined where the first value is an absolute value of a difference between the short term workload ratio and the long term workload ratio. First processing is performed that determines, in accordance with the first value and the short term workload ratio, whether to adjust any of the first portion of the processors and the second portion of the processors of the first configuration.
