Fastest Supercomputer in Europe is Cooled by Hot Water

MUNICH, Germany, June 18 -- The Leibniz Supercomputing Centre (LRZ), in collaboration with IBM, today announced the world's first commercially available hot-water cooled supercomputer, a powerful, high-performance system designed to help researchers and industrial institutions across Europe investigate and solve some of the world's most daunting scientific challenges.

Timeline: IBM's History and Future in Water Cooled Computing (1966-2060)

The new LRZ "SuperMUC" system was built with IBM System x iDataPlex Direct Water Cooled dx360 M4 servers with more than 150,000 cores to provide a peak performance of up to three petaflops, which is equivalent to the work of more than 110,000 personal computers. Put another way, three billion people using a pocket calculator would have to perform one million operations per second each to reach equivalent SuperMUC performance. Also, a revolutionary new form of hot-water cooling technology invented by IBM allows the system to be built 10 times more compact and substantially improve its peak performance while consuming 40 percent less energy than a comparable air-cooled machine.

"This year all the electricity consumed by state-funded institutions across Germany are required to purchase 100% sustainable energy," said Prof. Dr. Arndt Bode, Chairman of the Board, Leibniz Supercomputing Centre. "SuperMUC will help us keep our commitment, while giving the scientific community a best-in-class system to test theories, design experiments and predict outcomes as never before."

Pioneering Hot-Water Cooled Technology

Up to 50 percent of an average air-cooled data center's energy consumption and carbon footprint today is not caused by computing, but by powering the necessary cooling systems. IBM scientists and developers chose to address this challenge with an innovative concept of hot-water cooling, which eliminates the need for conventional data center air cooling systems. IBM's hot-water cooling technology directly cools active components in the system such as processors and memory modules with coolant temperatures that can reach as high as 113 degrees Fahrenheit, or 45 degrees Celsius.

"As we continue to deliver on our long-term vision of a zero emission data center we may eventually achieve a million fold reduction in the size of SuperMUC, so that it can be reduced to the size of a desktop computer with a much higher efficiency than today," said Dr. Bruno Michel, manager, Advanced Thermal Packaging, IBM Research.

SuperMUC combines its hot-water cooling capability, which removes heat 4,000 times more efficiently than air, with 18,000 energy-efficient Intel Xeon processors. In addition to helping with scientific discovery, the integration of hot-water cooling and IBM application-oriented, dynamic systems management software, allows energy to be captured and reused to heat the buildings during the Winter on the sprawling Leibniz Supercomputing Centre campus, for savings of one million Euros ($1.25 million USD) per year.

Europe's Most Powerful Supercomputer

The SuperMUC system is Europe's fastest computer, according to the TOP500 list of the world's fastest supercomputers announced today. This performance will be used to drive a wide spectrum of research -- from simulating the blood flow behind an artificial heart valve, to devise quieter airplanes to unearthing new insights in geophysics, including the understanding of earthquakes. The SuperMUC system is also connected to powerful visualization systems, including a large 4K stereoscopic power wall and a five-sided immersive artificial virtual-reality environment or CAVE for visualizing 3D data sets from fields, including Earth science, astronomy and medicine.

The LRZ is the computer center for Munich's universities and for the Bavarian Academy of Sciences and Humanities. It takes care of the scientific data network in Munich, offers a variety of data services, and provides high-end computing facilities for the scientific community across Europe.

The center's new SuperMUC system is the largest in Europe and one of the most powerful systems in the world. It is part of the Partnership for Advanced Computing in Europe (PRACE) high-performance computing infrastructure for researchers and industrial institutions throughout Europe. The supercomputer is jointly funded by the German federal government and the state of Bavaria. It will be officially inaugurated in July 2012 at Leibniz Supercomputing Centre in Garching, Germany.

Exascale Computing: The View from Argonne

As a result of the dissolution of DARPA's UHPC program, the driving force behind exascale research in the US now resides with the Department of Energy, which has embarked upon a program to help develop this technology. To get a lab-centric view of the path to exascale, HPCwire asked a three of the top directors at Argonne National Laboratory -- Rick Stevens, Michael Papka, and Marc Snir -- to provide some context for the challenges and benefits of developing these extreme scale systems.

TOP500 Gets Dressed Up with New Blue Genes

The 39th TOP500 list was released today at the International Supercomputing Conference in Hamburg, Germany, with a new machine at the top. Sequoia, an IBM Blue Gene/Q machine, delivered a world record 16 petaflops on Linpack, knocking RIKEN's 10-petaflop K Computer into second place. The Japanese K machine had held the TOP500 title for a year.

Intel Will Ship Knights Corner Chip in 2012

On Monday at the International Supercomputing Conference in Hamburg, Intel announced that Knights Corner, the company's first manycore product, would be in production before the end of 2012. The company also released a few more details about the upcoming product line, including the creation of a new Xeon brand for the architecture, some performance updates on pre-production silicon, and Cray's adoption of MIC as part of its future Cascade supercomputer.
