Estimation of power consumption for a job based on adjusted calculation of similarities between jobs

A method performed by a computer, the method comprising:

• calculating, based on words within a plurality of documents respectively corresponding to a plurality of jobs, an attribute of a first job that is newly submitted and an attribute of each of a plurality of second jobs that have been executed, a first similarity level indicating a level of similarity of the words within a first document corresponding to the first job and each of a plurality of second documents respectively corresponding to the plurality of second jobs by using a first calculation expression;
• identifying, based on the first similarity level calculated for each of the plurality of second jobs, one of the plurality of second jobs whose corresponding second document is most similar to the first document as a first candidate job;
• estimating, based on second power waveforms respectively indicating power consumed by executing the plurality of second jobs with a high-performance computing system, first power consumption to be consumed by executing the first job at power consumption indicated by a second power waveform of the first candidate job;
• obtaining, after the first job is executed, a first job power waveform indicating power consumption that has been consumed by executing the first job;
• calculating, based on the first job power waveform and the second power waveform, for at least one of the plurality of second jobs, a second similarity level indicating a level of similarity of power consumption between the first job and the at least one of the plurality of second jobs;
• identifying, based on the second similarity level calculated for the at least one of the plurality of second jobs, one of the at least one of the plurality of second jobs whose second power waveform is most similar to the first job power waveform as a second candidate job;
• and
• adjusting the first calculation expression to increase the first similarity level to be calculated between the first job and the second candidate job, wherein:
• the calculating the first similarity level includes calculating the first similarity level by using weights of individual topics determined based on the words within the plurality of documents, the first calculation expression using the weights to cause a similarity level between two documents including a particular topic to increase as a value of weight of the particular topic increases;
• the adjusting the first calculation expression includes increasing the value of weight of a topic included in the document of the second candidate job;
• and
• controlling power consumption of the high-performance computing system based on the adjusted first calculation expression.
