Using very high-resolution numerical simulations, astrophysicists at the CEA and CNRS, led by Florent Renaud , have, for the very first time, achieved a detailed analysis of the effects of turbulence generated when two galaxies collide. These numerical simulations, in which the disordered motions of the gas contained in galaxies are seen at extremely small-scale resolutions, at last explain a phenomenon that astrophysicists have observed but which they have been unable to understand until now: that of “starbursts” of star formation when galaxies collide. A process of compressive turbulence helps to explain such starbursts, and why some galaxies form more stars than others. These results are published in Monthly Notices of the Royal Astronomical Society, Letters, May 2014.
Albatern’s wave power generation product consists of buoyant Squid modules which have three arms and are capable of linking with up-to three other Squids. The Squid modules and their link-arms contain mechanisms to generate power, capturing the heave and surge motion of the waves via hydraulics. In this way, Albatern an innovative Scottish SME of 15 engineers has developed a highly scalable, modular wave power generator. Albatern’s project supported by PRACE SHAPE marked the start of the development of a physics code capable of simulating and predicting the power of a large scale Wavenet array (100 or more devices).
PSA Peugeot Citroën collaborated with Altair, Ecole Polytechnique Laboratoire de Mécanique des Solides (LMS) and PRACE to perform a study of automotive crash rupture simulations, investigating ways to improve material failure criteria and better predict cracks.
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.
