NVIDIA GPU-Accelerated Supercomputer Sets World Record for Energy Efficiency

Italy's "Eurora" supercomputer -- which uses NVIDIA Tesla GPU accelerators based on NVIDIA Kepler, the world's fastest and most efficient high performance computing (HPC) architecture -- has set a new record for data center energy efficiency, NVIDIA today announced. The Eurora supercomputer, built by Eurotech and deployed Wednesday at the Cineca facility in Bologna, Italy, the country's most powerful supercomputing center, reached 3,150 megaflops per watt of sustained performance -- a mark 26 percent higher than the top system on the most recent Green500 list of the world's most efficient supercomputers.

Eurora broke the record by combining 128 high-performance, energy-efficient NVIDIA Tesla K20 accelerators with the Eurotech Aurora Tigon supercomputer, featuring innovative Aurora Hot Water Cooling technology, which uses direct hot water cooling on all electronic and electrical components of the HPC system.

Available to members of the Partnership for Advanced Computing in Europe (PRACE) and major Italian research entities, Eurora will enable scientists to advance research and discovery across a range of scientific disciplines, including material science, astrophysics, life sciences and Earth sciences.

"Advanced computer simulations that enable scientists to discover new phenomena and test hypotheses require massive amounts of performance, which can consume a lot of power," said Sanzio Bassini, director of HPC department at Cineca. "Equipped with the ultra-efficient Aurora system and NVIDIA GPU accelerators, Eurora will give European researchers the computing muscle to study all types of physical and biological systems, while allowing us to keep data center power consumption and costs in check."

Pairing NVIDIA Tesla K20 GPUs with Eurotech's Aurora Hot Water Cooling technology, the Eurora system is more efficient and compact than conventional air-cooled solutions. HPC systems based on the Eurora hardware architecture, including the Eurotech Aurora Tigon, enable data centers to potentially reduce energy bills by up to 50 percent and reduce total cost of ownership by 30-50 percent.

In addition, the use of Aurora Hot Water Cooling technology reduces or eliminates the need for air conditioning in typically warm climates like Italy. The thermal energy the system produces can be used to heat buildings, drive adsorption chillers for air conditioning or generate tri-generation, the combined production of electricity, heating and cooling.

"GPU accelerators are inherently more energy efficient than CPUs, and Tesla K20 accelerators widen this gap considerably," said Sumit Gupta, general manger of the Tesla accelerated computing business at NVIDIA. "Energy efficiency has become the defining element of computing performance. And GPUs enable data center computer systems of all sizes -- from small clusters to future exascale-class systems -- to achieve performance goals within an economically feasible energy budget."

Eurora is a prototype system developed for Cineca under the PRACE 2IP initiative to provide a sustainable, high-quality infrastructure to meet the most demanding needs of the European HPC user community. A commercial version of the Eurotech Aurora Tigon supercomputer is also available today from Eurotech. More information is available on the Eurotech website.

Can it play crysis 3?


To be honest, I am not sure if I even see a gpu or cpu in that pic. I am familiar with that kind of system though.

If so, how does the GeForce GRID work then? :wtf:

Oh wait, it's not for enthusiast gaming anyway...

The same as normal water cooling, they just don't strive to keep the water at low temperatures. So by cooling it to around 50~60 C, the water is "cold" enough to cool the chips sufficiently as they are fine running at those temperatures.

Makes no sense to me what so ever but appears to be correct, some more info:
