Updated Energy Efficiency Rating of Green500 Supercomputers

Published

on

The next edition of the Green500 rating was published yesterday. Let us remind you that the world’s most high-performance supercomputers are ranked in terms of energy efficiency. While the ranking “tends to make steady progress,” there is no sign of a quantum leap towards new technologies, according to the list’s compilers.

The Japanese MN-3 system returned to the first place in the Green500 ranking, having been pushed back from the top by the American Nvidia DGX SuperPOD system. The MN-3 is based on MN-Core accelerators optimized for matrix arithmetic and Xeon Platinum 8260M processors. With an energy efficiency of 29.70 gigaflops / watt, the system takes only 337 place in the TOP500 absolute performance rating.

US supercomputer HiPerGator AI ranks second with an energy efficiency of 29.52 gigaflops / watt. This system is based on AMD EPYC 7742 processors and Nvidia accelerators. Note that it has 138,880 cores – much more than any other system in the Green500 top five. This system is ranked 22nd on the TOP500 list.

The Wilkes-3 from the UK, built by Dell EMC, is the third. This supercomputer is also built on AMD processors. More precisely, on AMD EPYC 7763 processors. It demonstrates an energy efficiency of 28.14 gigaflops / watt.

The Luxembourg MeluXina system, which ranks fourth in the Green500 rating, is also built on AMD EPYC processors. Its energy efficiency is 26.96 gigaflops / watt, and it ranks 37th in the TOP500.

The American system Nvidia DGX SuperPOD, which was mentioned above, closes the five leaders in Green500. The supercomputer on AMD EPYC 7742 processors and Nvidia A100 accelerators is characterized by an energy efficiency of 26.20 gigaflops / watt.

The complete rating is published on the TOP500 website.

12 million kilometers without changing the battery with zero risk

This week, BYD said in an investor communication that BYD Blade’s state-of-the-art battery packs can be charged and discharged more than 3,000 times. This allows you to cover 1.2 million kilometers without changing batteries.

BYD previously said its new BYD Blade vehicle battery will be a game-changer and usher in a new era of safety and performance for the electric vehicle industry.

In last year’s ranking of global battery manufacturers, BYD’s total installed battery capacity in electric vehicles reached 26.3 GWh. This allowed BYD to take the fourth place in the world with a market share of 8.8%.

Today, all BYD vehicles powered by new energy sources are equipped with BYD Blade batteries. Sales of all models such as Han, Tang, Song and Dolphin have exceeded 10,000 units in China alone.

In addition, the batteries have passed numerous tests, which have confirmed that they do not suffer from the problem of spontaneous combustion, even if the shell and geometry are damaged.

It will replace the Passat Volkswagen ID introduced AERO

Volkswagen introduced the ID sedan. AERO, which is built on the pure electric MEB platform. In addition, the dimensions and technical parameters were disclosed.

The car received a body with a drag coefficient of only 0.23Cd. Volkswagen ID. AERO is positioned as a mid-size sedan, its length, width and height are 4975, 189 and 1528 mm, respectively. Thanks to the advantages of a purely electric platform, its wheelbase reaches almost 3 m (2966 mm). According to Volkswagen’s official statement, it has an interior space comparable to the Phaeton.

It is often said that there is not enough chips

Japan’s largest semiconductor makers, from Toshiba to Sony, have warned that a shortage of engineers is threatening the government’s efforts to revive the domestic chip industry.

The expected labor crisis comes as Japan works to increase investment in the semiconductor sector as part of efforts to bolster its economic security amid the chip shortage caused by the Covid-19 pandemic.

In an address to the Ministry of Economy, Trade and Industry last month, the electronics industry group said that over the next few years, Japan has the best chance of regaining its position in the semiconductor market.

“It is often said that there is not enough chips, but most of all, engineers are missing.”  Japan's largest chip makers face shortage of specialists

The Japan Electronics and Information Technology Manufacturers Association said the sector’s success depends on attracting enough people to innovate and run chip factories. It is estimated that eight major manufacturers will need to hire about 35,000 engineers over the next 10 years to keep up with the pace of investment.

“It is often said that there is not enough chips, but most of all, there is not enough engineers,” said Hideki Wakabayashi, a professor at the University of Tokyo and head of the policy proposal task force at the JEITA Semiconductor Committee.

To support innovation and search for potential employees, Toshiba, Sony and other companies are collaborating with the best scientific departments across the country and investing additional resources in chip research and recruitment.
