  • Patent number: 12159169
    Abstract: An information processing apparatus calculates a first load value indicating the load of a plurality of first jobs whose used node counts are less than or equal to a threshold among jobs waiting for execution, and a second load value indicating the load of a plurality of second jobs whose used node counts exceed the threshold among the waiting jobs. If load conditions including one where the first load value exceeds the second load value are satisfied, the information processing apparatus combines two or more first jobs among the plurality of first jobs to create a combined job whose used node count exceeds the threshold. The information processing apparatus causes a first node group to execute the remaining first jobs among the plurality of first jobs and causes a second node group to execute the combined job and the plurality of second job.

  • 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.
