Everyone is well aware of the
TOP500 rating, in which all the most powerful supercomputers are ordered by their computing power. But in order to determine the perfection of any computing system, they are guided not only by a single indicator. Take, for example, a car, because you won’t evaluate it by taking only the maximum speed indicator, of course, the fuel consumption per kilometers traveled will be taken into account. For supercomputers, there is another
Green500 rating.

When compiling the Green500 rating, the following main criteria for evaluating a supercomputer are taken into account:
- performance
- power consumption level
- the ratio of computing power to the amount of energy consumed (flops per watt of consumed electricity)

In the November list of Green500 results, the ASUS ESC4000 G2S supercomputer at the Helmholtz Center for the Study of Heavy Ions, which is located in Darmstadt, is
named the most efficient. GSI Center conducts research using heavy ion accelerators. Their L-CSC cluster reaches 5.27 gigaflops per watt (billions of operations per second per watt). In the list of the most powerful supercomputers in the monthly TOP500, he was ranked 168th. For comparison, MilkyWay-2 c 1.9 gigaflop per watt ranks first in the TOP500 rating for the fourth time in a row.

The L-CSC cluster equipped with 160
ASUS ESC4000 G2S supercomputer
servers based on
AMD FirePro S9150 graphics processors, an array of 112
Intel Xeon E5-2690 v2 processors and 896th 1.35v DDR3-1600 memory modules each showed such an impressive result 5.27 gigaflops per watt. If you take the energy efficiency indicators of the machine, which took the first place in the previous Green500 rating in June 2014, then the L-CSC cluster is 20% higher than its “predecessor”.

“Working with AMD to create a research supercomputer at GSI has taken our company to a new level. We are proud that, as part of the project, we can offer our customers solutions aimed at improving energy efficiency and productivity, ”said Tom Lin, general manager of server solutions at ASUS. “Thanks to the ASUS ESC4000 G2S servers and AMD FirePro graphics cards, the supercomputer at the GSI center creates tremendous computational capabilities for our research,” said Dr. Volker Linderstrut, professor at the Goethe University of Frankfurt, head of the IT department at GSI and chairman of the Frankfurt Institute of Advanced Research.
Hopefully, not much time will pass and supercomputers of our research institutes, as well as other institutions where there is a need for such computational power, will appear in such ratings. In the meantime, we continue to follow the world of "super cars" ...
