COMPUTATIONAL RESOURCE MANAGEMENT DEVICE, COMPUTATIONAL RESOURCE MANAGEMENT METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A computational resource management device 10 is provided with: a model-learning unit 11 for learning a model that indicates the relation of an execution time and a resource using, for training data, the measured value of execution time of data processing, the measured value of a resource amount, and the feature of input data; an execution time estimation unit 12 for inputting the feature of data expected to be inputted to the model and calculating the estimated value of execution time of data processing expected to be executed; a resource amount calculation unit 13 for calculating the amount of a resource needed for the data processing expected to be executed, using the estimated value of execution time, a fluctuation index indicating the fluctuation of the estimated value of execution time, and the distribution of estimation residuals; and an execution plan creation unit 14 for creating an execution plan for the data processing expected to be executed, on the basis of the estimated value of execution time, the fluctuation index, the distribution of estimation residuals, and the calculated amount of a resource.
