The purpose of the research is to design effective energy consumption algorithms for optimizing program loops of user application and system software. The work is aimed at a range of methods of static parallelization. The main approach is the transformation of the program code, in which we get the program code in the same language at the output, but transformed and optimized for compilation by standard means and execution on a parallel computing system. It is shown that the use of planning methods for the iterative space of cycles is effective for the process of parallelization of cycles. It is shown that the main component of energy consumption in calculations is the dynamic costs, which depend on the frequency, voltage, capacity of the schemes and the activity of the elements of the system. By changing these parameters, one can reduce the system power consumption. The use of optimization of cycles, that is, those places where the most concentrated computing work is proposed, in order to reduce the activity of system elements is proposed. So, increasing the location of programs, we reduce the amount of data forwarding from memory to the processor and in the opposite direction. A series of experiments have been carried out, the results of which show that it is possible to save electricity consumption up to 20-25%. Product Description popup.authors Novatska Olena M.
