Information processing system and information processing system control method

Abstract

An information processing system includes an execution block computational strength data area, a roofline model data storage unit, a computational strength data acquisition unit, and a performance power control unit. The execution block computational strength data area holds computational strength data of each execution block constituting an arithmetic application that operates in a computer system including a processor and a main storage apparatus. The roofline model data storage unit holds a roofline model corresponding to an operation frequency and the number of cores of the processor, and an operation frequency of the main storage apparatus. The computational strength data acquisition unit acquires computational strength data of each execution block. The performance power control unit controls an operation frequency and the number of cores of the processor and an operation frequency of the main storage apparatus based on the roofline model and the computational strength data of each execution block.
