    Abstract

    Efficiency optimization for the input/output functions and memory access for the HPC applications requires simultaneous considerations for the computational speed and the electricity consumption. The proposed study shows that for the substantial part of the calculations the increase of the clock frequency of the CPU does not lead to the increase of the application execution speed. Peripheral units work at a lower rate than the CPU. Therefore the speed of the peripheral devices will determine the speed of the application that uses them and the CPU clock may be adjusted to a lower rate with corresponding reduction of electricity consumption. In this work we arrive at the need for an application specific metrics that describes the computational advance for setting the CPU clock frequency to the optimal rate.
