Remaining switched on to silicon-based electronics

The difficulty of further increasing the power conversion efficiency of silicon-based components in power electronics seems to indicate that we are reaching the limits of potential advances to this technology. However, a ...

Using computer simulations to discover where Neanderthals lived

Archaeologist Fulco Sherjon has used computer simulations to identify where and how Neanderthals lived in West Europe. What stood out was that they probably had lots of children and lived in smaller groups than was previously ...

Exploring planetary plasma environments from your laptop

A new database of plasma simulations, combined with observational data and powerful visualisation tools, is providing planetary scientists with an unprecedented way to explore some of the Solar System's most interesting plasma ...

Image: Supercomputer simulation of magnetic field loops on the Sun

Magnetic fields emerging from below the surface of the sun influence the solar wind—a stream of particles that blows continuously from the sun's atmosphere through the solar system. Researchers at NASA and its university ...

Seeking out silent threats to simulation integrity

Large-scale computing has become a necessity for solving the nation's most intractable problems. Due to their sheer number of cores, high-end computers increasingly exhibit intermittently incorrect behaviors—referred to ...

Quantifying uncertainty in computer model predictions

DOE's National Energy Technology Laboratory (NETL) has great interest in technologies that will lead to reducing the CO2 emissions of fossil-fuel-burning power plants. Advanced energy technologies such as Integrated Gasification ...

UCSC acquires powerful new astrophysics supercomputer system

State-of-the-art computer systems have been instrumental in making UC Santa Cruz one of the world's leading centers for computational astrophysics and planetary science. A new supercomputer recently installed on campus provides ...

CASL milestone validates reactor model using TVA data

Today, the Consortium for Advanced Simulation of Light Water Reactors (CASL) announced that its scientists have successfully completed the first full-scale simulation of an operating nuclear reactor. CASL is modeling nuclear ...
