Another week has passed and it has been a busy time in the supercomputing sector. This week, in particular, stands out because so many innovative projects have come to fruition, leading to announcements pertaining to key advances made with the help of high-performance computing advances.
Scientists identify possible source of galactic asymmetry
Scientists believe that eons ago when the universe, as we know it, was formed, that a Big Bang occurred and led to the development of planets and other galactic bodies. A recent R&D report explained that scientists realized, approximately 60 years ago, that some form of asymmetry must have existed between matter and non-matter at the time of the big bang. Otherwise, the event would have led to the matter and non-matter cancelling one another out. If that happened, the universe would be made up of light and nothing else.
While scientists have long understood that this asymmetry was present, they did not know why it existed. Researchers, with the help of supercomputing systems, have made progress in solving the problem. The key issue at hand in this research, according to the report, was the breakdown of kaon particles into pions and other particles made up of quarks. Supercomputers simulating the process of decay have been able to identify some of the source of the matter-non-matter imbalance at the time of the Big Bang.
Taku Izubuchi, a theoretical physicist at the U.S. Dept. of Energy and researcher on the project, told the news source that the findings do not represent a complete solution to the asymmetry problem, but it is still an important insight into the issue.
Researchers gain insight into tornado formation
Central Michigan University researcher Leigh Orf and a team of scientists have completed promising simulations that could contribute to a better understanding of how tornados form, a recent report from the National Institute of Computational Sciences explained. The news source explained that the research, which involved multiple supercomputing systems, including Blue Waters, performing a simulation that created a complete model of a tornado.
Orf told the news source that the simulated tornado created by the simulation did not develop the kind of super cell framework that researchers are looking for to fully understand how large tornados form. However, it provide an excellent first step in that direction.
New methods could limit the impact of strokes
Researchers at the Universities of California at Berkeley and San Diego completed a project at the National Energy Research Scientific Computing Center that could lead to much more effective response and treatment of strokes, HPCWire reported.
According to the news source, strokes do damage through blood clots that prevent the brain from getting the oxygen it needs. The supercomputing project explored the potential of high intensity focused ultrasound and found that the method, which uses microbubbles, does have potential in the battle against strokes.
Department of Energy developing climate-change research project
The combined might of the Department of Energy’s supercomputing systems is powerful, and the DOE has begun a new project that could take full advantage of the power of the technology. A recent HPCwire article explained that the DOE is developing a project that will, for all intents and purposes, create a climate change time machine that allows researchers to travel back in time and simulate extreme weather events to track how the planet’s climate has changed over time. This information could also be used to more accurately understand current and future climate change issues.
The project will be run at the National Energy Research Scientific Computing Center and will track extreme weather going back to 1871 to create an effective virtual climate time machine. Resources from the Oak Ridge Leadership computing Facility will also be used on this project, the report said.
