CROSS-REFERENCE TO RELATED APPLICATION

This application is based upon and claims the benefit of priority of the prior Japanese Patent Application No. 2019-57325, filed on Mar. 25, 2019, the entire contents of which are incorporated herein by reference.

FIELD

The present disclosure relates to a job scheduler and a job schedule control method.

BACKGROUND

The electric power charge of the high-performance computing (HPC) system is determined by the maximum monthly value of the average value of power consumption in a certain time section. For this reason, the electric power charge is kept lower as the power consumption is leveled in each time section. Therefore, a technique for predicting the power consumption of the HPC system for leveling has been offered.

For example, Japanese Laid-open Patent Publication No. 2015-76091 and Japanese Laid-open Patent Publication No. 2000-276460 are disclosed as the related art.

SUMMARY

According to an aspect of the embodiments, a job scheduler includes a memory, and circuitry coupled to the memory and configured to, based on similarity between execution time and power consumption information of a plurality of jobs executed in a system, classifies the plurality of jobs into a plurality of groups, construct respective time series prediction models for the plurality of groups using a power waveform included in each of the plurality of groups as teacher data, predict a power waveform at a predetermined interval including a first time from each of the constructed time series prediction models, compare a power waveform at a predetermined interval including a first time of a job in execution for which power is to be predicted with the predicted power waveform of each of the plurality of groups to identify a similar time series prediction model from among the respective time series prediction models of the plurality of groups, based on the identified time series prediction model, predict power consumption at a predetermined interval including a second time for the job for which power is to be predicted, and control job execution based on the predicted power consumption.

The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention.
