Abstract:
1. A computer-implemented method for optimizing a parameter set composed of a plurality of system configuration parameters, comprising steps of: storing a plurality of parameter sets; selecting one of the plurality of parameter sets as a test parameter set to be evaluated; measuring performance only for one batch job out of N batch jobs constituting full set performance measurement for the test parameter set, where N is a positive integer; calculating an evaluation value based on a difference between an integral of measurement values obtained until the performance has been measured for r batch jobs constituting full set performance measurement, by using the test parameter set; and an integral of mean measurement values obtained by performing the performance measurement for the r batch jobs by using an optimal parameter set which is one of the parameter sets used in the performance measurement having been performed, where r is a positive integer less than N; determining whether or not the evaluation value has deviated from an evaluation continuing range of a width from a width W where r is equal to zero, to a width W′ where r is equal to N; and terminating the evaluation for the test parameter set on condition that the evaluation value is determined, in the determining step, to have deviated from the evaluation continuing range in a direction of performance deterioration, wherein at least one of the steps is carried out by a computer device.
