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.
Iron chalcogenides are a recently discovered family of superconductors. Professor Sandro Sorella of SISSA planned to investigate the nature of their superconductivity in a PRACE project, but soon realised that this would be impossible due to unforeseen factors. Instead, the project focused on investigating different methods for carrying out such simulations.
AmpliSIM is a web service that allows industrial engineering companies to model their environmental impact. As part of the SHAPE programme, Oliver Oldrini and Sylvie Perdriel have been parallelising models to optimise them for HPC clusters so that AmpliSIM can improve its service.
The newest generation of satellites can provide us with incredibly precise data about the surface of the Earth. Professor Xiaoxiang Zhu has been using high performance computers to decipher this data and is using it to provide support to some of the poorest urban areas in the world.
Blue energy, which is the free energy lost when salty sea water and less salty river water meet and mix in estuaries, could become a significant source of global electricity in the future. Capacitive mixing, an up-and-coming technique that exploits the charge-discharge cycle of capacitors can be used to harvest this energy but optimizing the devices employed here has been no easy task. Researchers in France have now shown that molecular simulations can realistically predict the capacitance of devices that contain nanoporous carbon materials as the electrodes and salty water as the electrolyte. When run in reverse this technique is also an efficient way to desalinate water in a process known as capacitive deionization.
A new method for calculating the electromagnetic effects involved in the weak decays of hadrons has been developed by researchers from the three universities and units of INFN in Rome and from the University of Southampton. They have now proved its effectiveness and plan to apply it to various quantities in the field of particle physics.
