The Large Scale Parallel Simulation Performed on the K computer was Awarded the ACM Gordon Bell Prize 2012のページです。 The group performed extremely large simulations with an unprecedentedly high level of efficiency. The number of dark matter particles simulated was two trillions, which is the world's largest dark matter simulation at present. Of the many varieties, the most accepted approach is Particle-In-Cell. A physicist with the University of Montreal and Piotr Smolarkiewicz, a weather scientist with the European Centre for Medium-Range Weather Forecasts in the U.K., has created a new kind of computer simulation of the sun's energy flow. (A femtometer is 10^-15 metres.) That may not sound like much but This cut-off has been well studied and comes about because high energy particles interact with the cosmic microwave background and so lose energy as they travel long distances. Neutron stars are almost entirely composed of neutrons and protons, the same subatomic particles in the center of atoms found here on earth, and are held together by a massive gravitational force. The PI, with his collaborators, is developing an alternative approach, the Boundary In- tegral Treecode (BIT) [2] and Gridless DSMC. Eastwood,Computer Simulation Using Particles, Bristol, Eng- land: IOP Publishing, 1988. So even using the world's most powerful supercomputers, physicists have only managed to simulate tiny corners of the cosmos just a few femtometers across. UW scientists from the Institute of Nuclear Theory (INT) are using computers to simulate and examine neutron stars, a stellar remnant that results from the gravitational collapse of a normal star during supernovae activities. Which creates and modifies the fields, the triumvirate (one) above suggests the magnetism is inherent in the particles and somehow on larger scales the sum of all the magnetic particles creates a super magnet so to speak. BIT is based on fast summation algorithms, which eliminates the need for a fixed .. This research was made possible by using a computer cluster devoted to these unique simulations and funded by the Canada Foundation for Innovation, as well as a supercomputer at CEA/CCRT in France. Their origin has been a puzzle since then, but astronomers have suggested that most of these particles are accelerated by fast-moving shock waves triggered by supernova explosions. They found that a superimposed lattice framework by nature imposes a fundamental upper limit on the energy particles can have, a contradiction with quantum chromodynamics10. The target of the award-winning simulation, presented at SC12, was the gravitational evolution of dark matter in the early Universe. Rays using a high-altitude balloon.
