  • Publication number: 20210365094
    Abstract: A job power consumption is predicted by a computer. For each waveform of a plurality of waveforms indicating a temporal change in power consumption of a job, divide the waveform into a plurality of partial waveforms each with a given length and creates a histogram for types of partial waveforms, and store the histogram in association with the waveform in a first storage area. A new histogram for a prediction target waveform of a new job is created. From the first storage area, waveforms respectively associated with a plurality of histograms to be combined together into an enlarged histogram in which each frequency of the created histogram is multiplied by a given number are selected. A power consumption of the new job is predicted by a prediction model adjusted by using the selected waveforms.
