Publication number: 20120195355Abstract: A communications system is provided for direct communications between powered elements. A controller hub injects a first message via a modulated communication signal onto a branch circuit using a hub-side power line communication (PLC) coupler. An element-side PLC coupler associated with a powered element in a set of powered elements detects the first message and sends an interrupt to a mini-controller in the powered element. The mini-controller receives the interrupt from the element-side PLC coupler, extracts the first message using the element-side PLC coupler; reads a destination identifier in the first message; compares the destination identifier in the first message to a mini-controller identifier in the mini-controller; sends an acknowledgement message back to the controller hub in response to the destination identifier in the first message matching the mini-controller identifier, and forwards the first message to the powered element.Type: ApplicationFiled: January 27, 2011Publication date: August 2, 2012Applicant: International Business Machines CorporationInventors: Wael R. El-Essawy, Thomas W. Keller, JR., Juan C. Rubio

Patent number: 7908493Abstract: A mechanism is provided for unified management of power, performance, and thermals in computer systems. This mechanism incorporates elements to effectively address all aspects of managing computing systems in an integrated manner, instead of independently. The mechanism employs an infrastructure for real-time measurements feedback, an infrastructure for regulating system activity, component operating levels, and environmental control, a dedicated control structure for guaranteed response/preemptive action, and interaction and integration components. The mechanism provides interfaces for user-level interaction. The mechanism also employs methods to address power/thermal concerns at multiple timescales. In addition, the mechanism improves efficiency by adopting an integrated approach, rather than treating different aspects of the power/thermal problem as individual issues to be addressed in a piecemeal fashion.Type: GrantFiled: June 6, 2007Date of Patent: March 15, 2011Assignee: International Business Machines CorporationInventors: Andreas Bieswanger, Michael S.

Patent number: 7533003Abstract: A weighted event counting system and method for processor performance measurements provides low latency and low error performance measurement capability. A weighted performance counter accumulates a performance count according to a plurality of event signals provided from functional units in the processor. Differing weights are applied to the event signals in according to the correlation between each event with processor performance. The weights may be provided from programmable registers, so that the weights can be adjusted under program control. The event signals may be combined to reduce the bit-width of the set of event signal, with mutually-exclusive events merged in single fields of the combinatorial result and events having the same weights merged according to a sub-total. The weights are applied to the combinatorial result and used to update a performance count. The performance count can then be used by power management software or hardware to make adjustments in operating parameters of the processor.Type: GrantFiled: December 5, 2007Date of Patent: May 12, 2009Assignee: International Business Machines CorporationInventors: Michael S.
