Comparative analysis of the energy efficiency of modern environmentally friendly computers

Бесплатный доступ

As a result of technological advances, the performance of computers is growing continuously, while at the same time, their energy consumption is growing, too. Computer development needs to focus increasingly on finding energy efficient solutions to keep the operation of supercomputer centers on a sustainable level. As a result, green computing is getting more and more important in the world of supercomputers as well. Our paper examines the technical data of supercomputers (HPC) - with a focus on performance and energy consumption - on TOP500 and Green500 lists released over the past 10 years. The computing capacity of the machines on the TOP500 list of the most powerful computers is growing exponentially. Until 2017 the rate of growth of the energy efficiency indicator was slower than that of the computing capacity, therefore the total energy consumption of the machines on the TOP500 list was continuously increasing. This trend seems to have changed; in the period from November 2016 to June 2017 the growth rate of the energy efficiency of supercomputers exceeded the increase in their computing capacity...
