摘要:
A computer system has plural partitions for running respective workloads. Reliability-indicating events are monitored and the resulting data is used by a workload manager in allocating computer resources to workloads.
摘要:
A computer system takes redundancy into account when allocating hardware resources to workloads in the event of a failure of a non-data-handling component.
摘要:
Computer processes are allocated among cores of a multi-core multi-processor system at least in part as a function of utilization histories of the processes.
摘要:
A method of reducing power consumption of a computing system by a predetermined amount comprises: selecting at least one memory component of the computer system for reduced power consumption based on the predetermined amount of power consumption reduction; and evacuating the selected at least one memory component to reduce the power consumption of the computing system by at least the predetermined amount.
摘要:
The present invention provides a computer-implemented limited right-to-use business method. In response to a command to change the right-to-use status of at least a first component, the right-to-use status of said processor is changed in a direction either from reserved to available or from available to reserved. Then, the power state of the component can be changed as a function of that direction.

摘要:
A computer system includes software running on a hardware platform. The hardware platform provides a platform manager having an user interface that is independent of that for a mission operating system running on said platform. The platform manager issues platform requests for power-setting adjustments. The software includes a mission operating system with a power controller incorporated in or running on the mission operating system. The power controller adjusts power settings for hardware devices at least in part as a function of the platform requests.

Methods of method of managing memory power usage in a computing device having two or more memory modules. By monitoring a system working set size of the computing device, a determination can be made if all active memory modules are needed for the system working set size. If not all active memory modules are needed for the system working set size, one or more of the active memory modules can be selected for power down. By evacuating data from the selected one or more memory modules, placing the evacuated one or more memory modules in a power-down state, and removing the powered-down memory modules from the active memory of the computing device, memory power usage can be reduced.
摘要:
A server manages power and performance. The server comprises a plurality of processor and associated storage and input/output interface components, arranged into a plurality of independent compute cells. One or more performance metrics descriptive of performance of the independent compute cell plurality are selected and an optimization evaluation of the one or more performance metrics is performed. The independent compute cell plurality is tuned based on the optimization evaluation.
