Predicting Unruly Plasma Behavior with Simulations

Multiscale gyrokinetic simulations at NERSC are helping to determine whether electron energy transport in a tokamak plasma discharge is multiscale in nature. Being able to accurately predict electron energy transport is critical for predicting performance in future reactors such as ITER, currently under construction in France. More>

A TOAST for Next Generation CMB Experiments

Achieving a critical milestone for CMB (Cosmic Microwave Background) experiments, researchers scaled their data simulation and reduction framework TOAST to run on all 658,784 Intel Knights Landing Xeon Phi processor cores on NERSC’s Cori supercomputer. A new module to simulate the noise introduced when telescopes view the CMB was also implemented. More>

Big Bang, the Movie…Thanks to New Computing Breakthrough

In a new approach to enable scientific breakthroughs, researchers at Argonne National Lab and the University of Illinois linked together supercomputers to transfer massive amounts of data to run two different types of demanding computations in a coordinated fashion. This is particularly useful for cosmology simulations. NERSC is among the facilities assisting with this research. More>

Noble Gases Trapped in 2D Porous Structures at Room Temp for First Time

Scientists have discovered atoms of argon gas trapped inside a 2-D structure’s nanosized pores. Argon and other noble gases have previously been trapped in 3-D porous materials. This discovery, corroborated at NERSC, could help the design of new materials for gas separation and nuclear waste remediation. Calculations at the NERSC corroborated the research team’s findings.

Simulations Show How Recycled Atoms Boost Plasma Turbulence

Using supercomputers at NERSC, physicists at the DOE’s Princeton Plasma Physics Lab for the first time have modeled how the recycled neutrals, which arise when hot plasma strikes a tokamak’s walls, increase turbulence driven by what is called the “ion temperature gradient.” More>
