摘要： A method, apparatus, and computer-usable medium for predicting capacity on a data processing system. According to a preferred embodiment of the present invention, a capacity manager estimates an incremental power value utilize for activating and maintaining an additional processor in the data processing system. The capacity manager calculates a power headroom value. In response to calculating the power headroom value, the capacity manager determines whether an adjustment power headroom value is required. The capacity manager calculates a projected capacity value added by the additional processor to the data processing system.

摘要： A method, computer program product, and apparatus for managing power in a data processing system are presented. A core is activated in the data processing system and configured to operate at a frequency in response to receiving a request to increase a processing capacity of a set of resources in the data processing system. A determination whether a use of power resulting from activating the core configured to operate at the frequency meets a policy for the use of the power in the data processing system is made. A set of parameters associated with devices in the set of resources are adjusted to meet the policy for the use of power in the data processing system in response to a determination that the use of power does not meet the policy. A determination whether a number of operations performed per unit of time by a set of cores associated with the set of resources increased after activating the core is made. An indication that the request to increase the processing capacity of the set of resources is unavailable is made in response to a determination that the number of operations performed per unit of time by the set of cores associated with the set of resources has not increased.

摘要： The present invention thus provides for a method, system, and computer-usable medium that afford an equitably charging of a customer for computer usage time. In a preferred embodiment, the method includes the steps of: tracking an amount of computer resources in a Simultaneous Multithreading (SMT) computer that are available to a customer for a specified period of time; determining if the computer resources in the SMT computer are operating at a nominal rate; and in response to determining that the computer resources are operating at a non-nominal rate, adjusting a billing charge to the customer, wherein the billing charge reflects that the customer has available computer resources, in the SMT computer, that are not operating at the nominal rate during the specified period of time.

摘要： A mechanism is provided for scheduling application tasks. A scheduler receives a task that identifies a desired frequency and a desired maximum number of competing hardware threads. The scheduler determines whether a user preference designates either maximization of performance or minimization of energy consumption. Responsive to the user preference designating the performance, the scheduler determines whether there is an idle processor core in a plurality of processor cores available. Responsive to no idle processor being available, the scheduler identifies a subset of processor cores having a smallest load coefficient. From the subset of processor cores, the scheduler determines whether there is at least one processor core that matches desired parameters of the task. Responsive to at least one processor core matching the desired parameters of the task, the scheduler assigns the task to one of the at least one processor core that matches the desired parameters.
