    • A frequency manager automatically selects a clock frequency for each device or bus, or for a plurality of devices or buses, in a system, based on various factors and objectives. These factors and objectives can include optimizing performance of the devices without exceeding the system's power/thermal budget. The frequency manager can then control circuits that generate and provide clock signals having the selected frequency(ies) to these devices or buses. For example, in a system that is less than fully populated with devices, embodiments of the invention can select higher clock frequencies than a fully populated system would utilize. Some embodiments of the invention select higher clock frequencies for high-bandwidth devices than for low-bandwidth devices. Other embodiments use information about application programs that will be executed by systems, such as which devices these application programs will frequently access, to select higher clock frequencies for the frequently accessed devices. Yet other embodiments use information about whether the application programs are more memory or I/O intensive to allocate higher clock frequencies to either memory subsystems or I/O subsystems.
    • 频率管理器基于各种因素和目标,在系统中自动选择每个设备或总线或多个设备或总线的时钟频率。 这些因素和目标可以包括优化设备的性能,而不超过系统的功率/热预算。 然后,频率管理器可以控制生成并向这些设备或总线提供具有选定频率的时钟信号的电路。 例如,在小于完全填充设备的系统中,本发明的实施例可以选择比完全填充的系统将利用的更高的时钟频率。 本发明的一些实施例为高带宽设备选择较高的时钟频率而不是低带宽设备。 其他实施例使用将由系统(诸如这些应用程序将经常访问哪些设备)执行的应用程序的信息,以为频繁访问的设备选择更高的时钟频率。 其他实施例使用关于应用程序是否更多存储器或I / O密集型以将更高时钟频率分配给存储器子系统或I / O子系统的信息。

    • A rack equipment management system and method for providing a convenient and efficient manner to automatically manage rack equipment associated with information processing based upon power consumption and heat dissipation policies is presented. In one embodiment of the present invention, a rack equipment management system includes a rack equipment management policy data store, a management component, and a communication bus. The rack equipment management policy data store stores policy information related to rack equipment operations. The management component manages power consumption and thermal load of the rack equipment. The communication bus communicatively couples the rack equipment management policy data store and the management component.
