Abstract: The technology is generally directed to a management framework that uses a predictive feedback control loop to reduce energy consumption of a datacenter. The framework determines how to place a series of jobs or workloads on the available pool of machines in a datacenter. For example, the framework may consider the current workload profile and the workload demand forecast of the datacenter to determine an updated workload profile. The updated workload profile may include a redistribution of the workloads or jobs onto a first subset of the machines such that a second subset of the machines can enter an idle state.

Abstract: A programmable thermal dissipation power (TDP) system with integrated circuits is provided. The programmable TDP system includes a software interface, a monitoring circuit, and a controller circuit. The monitoring circuit may provide for the instantaneous input power supplied to the system. The controller circuit may monitor both the target TDP information specified from upstream and the input power readings. The controller circuit may generate a pulse-width modulation (PWM) signal that corresponds to a gap between the two power levels and sends the signal to the integrated circuits on the system. The integrated circuit may respond to the change in the input PWM signal and may adjust its power consumption. For example, the integrated circuit may adjust the clock frequency, adjust the instruction rate, skip a number of clock cycles, etc.

Abstract: A method for peak load shaving uses an energy storage device. A controller predicts the threshold above which the energy consumed by a load is equal to the capacity of the storage device. Load forecasting methods include artificial neural networks and support vector machines to compute a real-time threshold estimate that is used to decide when to dispatch power from the energy storage device. The threshold estimates are adapted iteratively, using the most recent observed load and previous threshold estimates. The adaptive algorithm reduces the peak demand charge assessed to the customer compared to existing static approaches that compute dispatch policies in advance.
