Abstract: A job processing method is provided. In this method, after receiving a to-be-processed job, a scheduling node in a high-performance computing system predicts, based on a category of the job, a quantity of resources consumed in real time in a process of executing the job. Because quantities of resources consumed in real time in a process of executing jobs of a same category are close, compared with a specified resource quantity, a predicted resource quantity is closer to a quantity of resources actually consumed by the job.

Abstract: Metal object detection may be performed in a wireless power system by monitoring the 5th or other order harmonic current of a dual-frequency power transmitter driven by a voltage-fed inverter with square-wave output. While power transfer is maintained by tuning at the fundamental frequency, the transmitter circuit is tuned simultaneously at the 5th order frequency or other harmonic frequencies to increase or decrease the flow of the harmonic current for when a metal object is present. The receiver circuit may include a notch filter to filter out the 5th order frequency. With the dual-frequency tuning configuration, the presence of a metal object causes a significant drop of the increase in the harmonic current at the transmitter side while the receiver behaves as an open circuit with no effect on power transfer. The harmonic tuning circuit may be switched off as necessary to leave only the fundamental frequency for power transfer.
