    Abstract: A method, system, and computer program product for system-wide power conservation using memory cache are provided. A memory access request is received at a location in a memory architecture where processing the memory access request has to use a last level of cache before reaching a memory device holding a requested data. Using a memory controller, the memory access request is caused to wait, omitting adding the memory access request to a queue of existing memory access requests accepted for processing using the last level of cache. All the existing memory access requests in the queue are processed using the last level of cache. The last level of cache is purged to the memory device. The memory access request is processed using an alternative path to the memory device that avoids the last level of cache. A cache device used as the last level of cache is powered down.

    Abstract: An indication of a first performance state is received, the first performance state being associated with a first voltage. The first performance state applies to at least one computing system component and the indication is received by a computing system component distinct from the requesting computing system component. An indication of a second performance state is received. The second performance state is associated with a second voltage that is different from the first voltage. It is determined whether the second performance state is within a range defined by a minimum and maximum performance state. Responsive to a determination that the second performance state is within the minimum and maximum performance state, the voltage of the at least one computing system component is set equal to the voltage associated with the second performance state.

    Abstract: A clamping current and voltage sensor provides an isolated and convenient technique for measuring current passing through a conductor such as an AC branch circuit wire, as well as providing an indication of an electrostatic potential on the wire, which can be used to indicate the phase of the voltage on the wire, and optionally a magnitude of the voltage. The device includes a body formed from two handle portions that contain the current and voltage sensors within an aperture at the distal end, which may be a ferrite cylinder with a hall effect sensor disposed in a gap along the circumference to measure current, or alternatively a winding provided through the cylinder along its axis and a capacitive plate or wire disposed adjacent to, or within, the ferrite cylinder to provide the indication of the voltage. When the handles are compressed the aperture is opened to permit insertion of a wire for measurement.

    Abstract: A system with scalable data collection for system management comprises a plurality of local data collectors and a system collector. Each of the local data collectors is coupled with a corresponding subsystem of the system. Each of the local data collectors is configured to periodically collect power management related data from the corresponding subsystem, and to format the collected power management related data for conveyance along any one of a plurality of channels between the local data collector and the system collector. The system collector is coupled with the plurality of local data collectors via the plurality of channels. The system collector selects from the channels between the system collector and each of the local data collectors based, at least in part, on channel states, and retrieves the power management related data collected by each of the local data collectors along a selected channel for the local data collector.
