Abstract

Systems, apparatuses, and methods for balancing computation and communication power in power constrained environments. A data processing cluster with a plurality of compute nodes may perform parallel processing of a workload in a power constrained environment. Nodes that finish tasks early may be power-gated based on one or more conditions. In some scenarios, a node may predict a wait duration and go into a reduced power consumption state if the wait duration is predicted to be greater than a threshold. The power saved by power-gating one or more nodes may be reassigned for use by other nodes. A cluster agent may be configured to reassign the unused power to the active nodes to expedite workload processing.

Processor power monitoring and control with dynamic load balancing

Patent Ardanaz, Federico; Steiner, Ian M.; Eastep, Jonathan M.; ...

Apparatus and methods may provide for subscribing a thread to a resource monitor through a machine specific register and subscribing the thread to a class of service through the machine specific register. The resource monitor or the class of service for the thread may be changed without interrupting the thread. The power allocated to the processor core may be changed based on the selected class of service for the thread.

Power line communication system and method of auto-commissioning system nodes

Patent Scott, Jeffrey Michael; Miu, Michael

A power line communication system and method permit auto-commissioning of multiple device control modules on a DC power line during the power up of the system. Device control modules associated with the peripheral devices are powered up sequentially and a unique address is assigned to each device controller when it is powered up. The device control modules have a unique circuit configuration that allows the use of inexpensive and mostly passive components. The cost effectiveness of the device controller design becomes particularly significant in applications, such as multi-panel OLED lighting fixtures, with high node counts.

Airborne wireless communication systems, airborne communication methods, and communication methods

Patent Deaton, Juan D [Menan, ID]; Schmitt, Michael J [Idaho Falls, ID]; Jones, Warren F [Idaho Falls, ID]

An airborne wireless communication system includes circuitry configured to access information describing a configuration of a terrestrial wireless communication base station that has become disabled. The terrestrial base station is configured to implement wireless communication between wireless devices located within a geographical area and a network when the terrestrial base station is not disabled. The circuitry is further configured, based on the information, to configure the airborne station to have the configuration of the terrestrial base station. An airborne communication method includes answering a 911 call from a terrestrial cellular wireless phone using an airborne wireless communication system.
