Italy sees two in top ten green supercomputer list

Italy sees two in top ten green supercomputer list

The resurgence of supercomputer technology in Japan has seen European system fall out of the top ten list of the most power efficient, green supercomputer systems. Just two supercomputers, both from Italy, are in the top ten most power efficient, and most powerful, such systems in the world. This compares to two from France and Spain last year.

HPC5 at EMI in Italy is used to model soil and rocks down to 15km in the search for il, but it is also being used for dynamic modelling of the Covid-19 proteins as part of the European EXSCALATE4CoV project.

The Dell EMC PowerEdge C4140 system uses Intel’s Xeon Gold 6252 24C 2.1GHz processor cores with NVIDIA’s Tesla V100 and Mellanox HDR Infiniband. The 669,760 cores use 2.2MW and deliver up to 51.7PFLOPS, making it the sixth most powerful machine on the planet and also the sixth most power efficient.

Eni is working with Cineca, a consortium of 70 Italian universities, eight research institutions and the Italian Ministry of Higher Education, which also has one of the HPC systems in the top ten.

The Marconi-100 at CINECA (above) ranks at 10 for power efficiency and 9 for performance. “To meet demand for more computing power, we refresh our HPC infrastructure every few years. However, as performance increases, so too does power consumption, which drives up energy costs,” said Carlo Cavazzoni, manager for HPC Development in the HPC Business Unit at CINECA.

The current HPC clusters have a power budget of over 3MW, so energy efficiency has been a key metric.

CINECA worked with E4 Computer Engineering and the University of Bologna, and in a PRACE (Partnership for Advanced Computing in Europe) project to provide the necessary processing power with the lowest possible energy consumption.

“In recent years, improvements in microprocessor and board design have helped to make HPC more energy-efficient. But running a supercomputer while keeping power consumption manageable is still a huge challenge, nd one that CINECA and PRACE were determined to take on,” said Cavazzoni.

This led to an IBM Power System AC922 using POWER9 16C 3GHz processors, Nvidia’s Volta V100 GPUs and dual-rail Mellanox EDR Infiniband. The system has 347,776 cores and

The most power efficient system is a new, relatively small supercomputer from Preferred Networks in Japan. The MN-3 has 2,080 cores and uses Intel’s Xeon Platinum 8260M 24C 2.4GHz processors and Preferred’s custom interconnect with a power consumption of 77kW.

The second most green supercomputer system is also a new one. Selene at Nvidia in the US uses AMD’s EPCY 7742 64C 2.25GHz processors with Nvidia’s latest A100 GPUs, giving a total of 277,760 cores and consumes 1.34MW.

Last year there were systems from Spain and France in the Green500 list with Spain and the UK in the list in 2018. However the list changes quickly – the prototype of the most powerful system in the world, Fugaku, that is at number nine in Green500 was at number 2 last November. However, the prototype at Fujitsu used a different interconnect technology.
