    摘要： Systems and methods are provided for optimizing the performance and/or allocation of constrained resources in a dynamic computing environment using adaptive regulatory control methods. For example, systems and methods for providing constrained optimization in a dynamic computing system implement model-based adaptive (self-tuning) regulatory control schemes that are designed to handle the system dynamics and which take into consideration control costs (such as the overheads of changing resource allocations and performance degradation due to transient load imbalances) to find an optimal solution. To facilitate practical application, a dual control architecture is disclosed which combines a heuristic fixed step control process that is implemented when there is no valid system model for model-based control. A system model is continually obtained and validated during run-time to adapt control parameters to variations in system dynamics.

    摘要： In one embodiment, functional system elements are added to an autonomic manager to enable automatic online sample interval selection. In another embodiment, a method for determining the sample interval by continually characterizing the system workload behavior includes monitoring the system data and analyzing the degree to which the workload is stationary. This makes the online optimization method less sensitive to system noise and capable of being adapted to handle different workloads. The effectiveness of the autonomic optimizer is thereby improved, making it easier to manage a wide range of systems.

    摘要： Improved management feedback-based controller techniques are disclosed for use in accordance with a computing system. For example, a method for managing a computing system includes the following steps. At least one measured performance metric is obtained from the computing system being managed. At least one control input value is generated based on parameters including a control error and a control deadzone such that uncertainty associated with the computing system is accounted for in accordance with the parameters. The control error is determined from a computation comprising the at least one measured performance metric and at least one performance metric goal. The control deadzone is defined such that the control input value is not generated when the control error is within the control deadzone. The control input value is sent to the computing system to effectuate achievement of the at least one performance metric goal associated with the computing system.
