NVIDIA GPU-Accelerated Supercomputer Sets World Record for Energy Efficiency

Italy's Top Supercomputing Center Leapfrogs Current Green500 No. 1 System Using Kepler Accelerators, Liquid Cooling

SANTA CLARA, CA -- (Marketwire) -- 01/31/13 -- 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(1) -- a mark 26 percent higher than the top system on the most recent Green500 list of the world's most efficient supercomputers.(2)

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.(3)

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.

With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, along with new ways to engage with users.
The IoT is upon us, but today’s databases, built on 30-year-old math, require multiple platforms to create a single solution.
