Creating Balance in HPC on the Piz Daint Supercomputer

The flagship supercomputer at the Swiss National Supercomputing Centre (CSCS), Piz Daint, named after a mountain in the Alps, currently delivers 7.8 petaflops of compute performance, or 7.8 quadrillion mathematical calculations per second. A recently announced upgrade will double its peak performance, thanks to a refresh using the latest Intel Xeon CPUs and 4,500 Nvidia Tesla P100 GPUs.

In this video from PASC16, Annick V. Renevey from ETH Zurich describes her award-winning poster on peptide simulations at CSCS.

Supercomputing and the Search for Dark Matter

Over at CSCS, Simone Ulmer writes that Particle physicists using the Piz Daint supercomputer have determined what is known as the scalar quark content of the proton. The research will help efforts to detect and research dark matter.

PASC16 Wraps in Lausanne

Scientists from a wide range of disciplines gathered at the SwissTech Convention Center in Lausanne from 8 to 10 June 2016 for this year’s PASC Conference. The use of high-performance computing in their research was the common bond that brought them together. From 8 to 10 June, the SwissTech Convention Center played host to around 360 scientists from Europe, the USA, Canada, Japan, Russia, Saudi Arabia, South Africa and Singapore, offering plenty of space and scope for them to engage in an interdisciplinary discourse on current issues relating to scientific computing.

Supercomputing Hidden Lava Lakes

The Piz Daint supercomputer spotted a large reservoir of magma right below the tiny South Korean island of Ulleung. No harm to humans is expected, but the origin of the magma pool remains unclear.

Video: Accelerating Code at the GPU Hackathon in Delaware

In this video from the GPU Hackathon at the University of Delaware, attendees tune their code to accelerate their application performance. The 5-day intensive GPU programming Hackathon was held in collaboration with Oak Ridge National Lab (ORNL). “Thanks to a partnership with NASA Langley Research Center, Oak Ridge National Laboratory, National Cancer Institute, National Institutes of Health (NIH), Brookhaven National Laboratory and the UD College of Engineering, UD students had access to the world’s second largest supercomputer — the Titan — to help solve real-world problems.”

CSCS to Double Performance of Cray Supercomputer with GPUs

Europe’s most powerful supercomputer Piz Daint is being upgraded, a move that is expected to at least double its computing power. ETH Zurich is investing around CHF 40 million to allow researchers to perform simulations, data analyses and visualizations even more efficiently in the future. Although slightly reduced in physical size, Piz Daint will become considerably more powerful as a result of the upgrade, particularly because we will be able to significantly increase bandwidth in the most important areas,” says CSCS Director Thomas Schulthess.

DWD Weather Service in Germany Upgrades Cray Systems

Today Cray announced a contract to upgrade the supercomputers at Germany’s National Meteorological Service – the Deutscher Wetterdienst (DWD). Located in Offenbach, Germany, DWD is one of the world’s premier numerical weather prediction centers. “Supercomputers are absolutely vital to our mission of providing important meteorological services for the protection of life and property,” said. Dr. Jochen Dibbern, Member of the Executive Board at DWD. “Our Cray supercomputers are critical tools for our researchers and scientists, and it’s imperative that we equip our users with highly advanced supercomputing technologies.”

Video: Welcome to HPC in Switzerland

Michele de Lorenzi from the Swiss National Supercomputing Centre presented this talk at the 2016 HPC Advisory Council Switzerland Conference. “Founded in 1991, CSCS, the Swiss National Supercomputing Centre, develops and provides the key supercomputing capabilities required to solve important problems to science and/or society. The centre enables world-class research with a scientific user lab that is available to domestic and international researchers through a transparent, peer-reviewed allocation process. CSCS’s resources are open to academia, and are available as well to users from industry and the business sector. The centre is operated by ETH Zurich and is located in Lugano.”

Simulating the World’s Smallest Integrated Switch

This visualization from CSCS in Switzerland shows the world’s smallest integrated switch. “Researchers working under Juerg Leuthold, Professor of Photonics and Communications at ETH Zurich, have created the world’s smallest integrated optical switch. Applying a small voltage causes an atom to relocate, turning the switch on or off. ETH Professor Mathieu Luisier, who participated in this study, simulated the system using Piz Daint Supercomputer. The component operates at the level of individual atoms. “
