With the help of PRACE HPC resources, a team of physicists from France, Germany, and Hungary headed by Zoltán Fodor, a researcher from Wuppertal, has successfully calculated the tiny neutron-proton mass difference. The results of this research, published in the 27 March 2015 edition of Science, are considered a milestone by many physicists and confirm the theory of the strong interaction.
Each year, hundreds of millions of tons of exposed soil from the Sahara Desert lifts into the air on gusts of wind. Once those dust particles are airborne, they may travel thousands of miles, affecting weather and air quality as far away as Europe and even the Americas.
On 18 November 2014, International Data Corporation (IDC) announced the eighth round of recipients of the HPC Innovation Excellence Award at the SC’14 high performance computing (HPC) conference in New Orleans, Louisiana. Two sets of winners are announced each year, at the November SC conference in the U.S. and the June ISC HPC conference in Germany. This round saw a second winner from PRACE SHAPE, after the award for Thesan in June.
We call it ‘The Big C’, but cancer is not just one disease. Breast cancer, for example, consists of over one hundred different diseases. Every cancer, even those from the same site on the body, behaves differently. That means that treating cancer—and curing it—is a long way from one-size-fits-all.
Researchers at the Nanoscience Center and Faculty of Information Technology in the University of Jyväskylä, Finland, have achieved a significant step forward in predicting atomic structures of hybrid nanoparticles. The work was carried out using supercomputing resources at CSC – IT Center for Science Ltd., Finland and at the Barcelona supercomputing center (BSC), Spain, as a part of a PRACE (Partnership for Advanced Computing in Europe) project.
The power of HPC for solving problems is unrivalled, but it is not always easily accessible for small companies and those working in fields with low levels of computing expertise. The company Polyhedra Tech is aiming to change this through a PRACE SHAPE project. Its co-founder Pau Fonseca i Casas explains how they are optimising the SDLPS simulator for use in a number of different fields.
Successfully navigating spacecraft safely back into the Earth’s atmosphere is one of the pinnacles of human engineering, where the slightest miscalculation can lead to catastrophe. Marco Cisternino of scientific computing SME OPTIMAD has been working alongside PRACE as part of its SHAPE Programme to try and optimise the codes needed for this endeavor for state-of-the-art parallel computing architectures.
What exactly happens inside neutron stars – the final stage of a giant star – is subject to speculation. In terms of physics, the interiors of neutron stars, cold atomic gasses and nuclear systems all have one thing in common: they are gaseous systems made up of highly interactive, superfluid fermions. Researchers fed the supercomputer “Piz Daint” with a new simulation method, and the results are finally offering insight into unknown processes of such systems.
Water is an ubiquitous chemical substance and a key ingredient for life, but its structure remains poorly understood. Dr Michele Casula and his colleagues from Sorbonne University, Paris, and from SISSA, Trieste have been shedding light on the complex arrangement of the intermolecular network in water using newly-devised numerical methods.
