Cerebrovascular accidents (CVA) are caused by a perturbation in the blood supply of the brain leading to a quick loss of cerebral functions, that is very often lethal. There are two categories of CVA: ischemic CVA (80% cases) resulting from the occlusion of a cerebral artery and haemorrhagic CVA (20% cases) provoked by a bleeding vessel.
Simulating the Universe from its birth to present day – no, not on a holo-deck or in a computer game, but through a high-fidelity model on Europe’s most powerful supercomputers – is what Prof. Volker Springel and his team at the Max-Planck-Institute for Astrophysics in Garching, Germany, have been using an allocation of 20 million core hours on the French Tier-0 system CURIE for.
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.
The Research Infrastructure PRACE (Partnership for Advanced Computing in Europe) welcomes the full installation of the French supercomputer CURIE, the second Tier0 system for PRACE, which will be completely opened to scientists on March 1st, 2012. Made available by GENCI, which represents France – one of the four hosting members in PRACE, and provided by Bull, the supercomputer CURIE has been installed in two phases since the end of 2010 and is now fully operational. During this period, CURIE has been gradually accessible for research purposes through the PRACE Regular and Preparatory Access Calls.
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.
