The new high-performance computer at the Potsdam Institute for Climate Impact Research ranks among the 400 fastest world-wide. This was announced today at the beginning of the International Supercomputing Conference in Frankfurt, Germany. The machine is able to do 212 trillion calculations per second – so called Teraflops. This allows simulations of the complex interactions between atmosphere, oceans, land and ice-sheets to a much larger extent than was hitherto possible on site. The computer’s waste heat is used – environmentally-friendly – to heat the new PIK research building.
“The new computer is to us what a research vessel is to other institutes – it allows us to explore the seas of the unknown, only that our oceans consist of data and equations,” says PIK director John Schellnhuber.
“We’re calculating changes in our Earth system: from past ice-ages to the impacts of human-made climate change on weather extremes, crop yields, or sea levels.” The new high-performance computer offers new possibilities to do this since it allows 6 to 9 times more simulation runs – like experiments in a laboratory, but with data.
The European Union financed 3 of the 4.4 million euro that the computer cost. In a Europe-wide tender, the company IBM came up with the best quality. “We really appreciate that our funders are recognizing the particular research challenge posed by climate change – so we could invest to get an ever clearer picture of the risks for people all over the world,” says Schellnhuber.
Innovative cooling system: Waste heat is used to heat buildings
Because computers inevitably produce heat when working, the manufacturer developed a highly innovative cooling system which pumps liquids directly to the currently installed 5088 processor kernels. The waste heat is used to heat the new research building of PIK with more than 200 working places to be occupied in a few weeks, and some neighbouring facilities. No additional heat sources are needed.
“The new high-performance computer is intricately tailored to fit our needs to develop climate and economic models – from the computing power and data transfer speed to the software,” says Karsten Kramer, head of IT at PIK with more than 20 years of experience in high-performance computing. The new system perfectly complements but doesn’t substitute existing computing resources in Germany, he stresses. The computer as well as the data centre are designed to allow further appropriate upscaling without performance interruptions.
“To substitute the computing power of the newly installed device, each person on Earth would have to do almost 30,000 calculations per second – this illustrates that we need this cutting-edge technology,” says Kramer. “Conversely, without the ideas of our scientists even the fastest computer would be useless.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
