Abstract: A device, system, and method are directed towards managing threads in a computer system with one or more processing units, each processing unit having a corresponding hardware resource. Threads are characterized based on their use or requirements for access to the hardware resource. The threads are distributed among the processing units in a configuration that leaves at least one processing unit with threads that have an aggregate zero or low usage of the hardware resource. Power may be reduced or turned off to the instances of the hardware resource that have zero or low usage. Distribution may be based on one or more of a number of specifications or factors, such as user power management specifications, power usage, performance, and other factors.

Abstract: A device, system, and method are directed towards managing power consumption in a computer system with one or more processing units, each processing unit executing one or more threads. Threads are characterized based on a cycles per instruction (CPI) characteristic of the thread. A clock frequency of each processing unit may be configured based on the CPI of each thread assigned to the processing unit. In a system wherein higher clock frequencies consume greater amounts of power, the CPI may be used to determine a desirable clock frequency. The CPI of each thread may also be used to assign threads to each processing unit, so that threads having similar characteristics are grouped together. Techniques for assigning threads and configuring processor frequency may be combined to affect performance and power consumption. Various specifications or factors may also be considered when scheduling threads or determining processor frequencies.

Abstract: A device, system, and method are directed towards managing threads and components in computer system with one or more processing units. A processor group has an associated hierarchical structure containing nodes that may correspond to processing units, hardware components, or abstractions. The processor group hierarchy may be used to assign one or more threads to one or more processing units, by traversing the hierarchy based on various factors. The factor may include load balancing, affinity, sharing of components, loads, capacities, or other characteristics of components or threads. A processor group hierarchy may be used in conjunction with a designated processor set.
