A team of researchers at the Berkeley Lab, PNNL and Intel are working hard to make sure that computational chemists are prepared to compute efficiently on next-generation exascale machines. Recently, they achieved a milestone, successfully adding thread-level parallelism on top of MPI-level parallelism in the planewave density functional theory method within the popular software suite NWChem. » Read More

Using decades of global climate data generated at a spatial resolution of about 25 kilometers squared, researchers were able to capture the formation of tropical cyclones, also referred to as hurricanes and typhoons, and the extreme waves that they generate. Those same models, when run at resolutions of about 100 kilometers, missed the tropical cyclones and the big waves up to 30 meters high. » Read More

Berkeley Lab is preparing for quantum computing future and Luis Alvarez Fellow in Computing Science Jarrod McClean is hard at work to find ways to exploit this new computing paradigm to simulate and predict the chemistry and properties of advanced compounds before scientists go into the lab to make them. His work of yoking quantum processors with classical HPC systems into a hybrid computer was highlighted in ASCR Discovery. » Read More

Materials discoveries are typically driven by their potential for industrial and commercial applications. In a new Perspective article, Nils Zimmermann and Maciej Haranczyk unravel trends in zeolite discoveries. They find that current efforts in the field look similar to past trends that were little effective in establishing new mature technologies. » Read More

Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using supercomputing resources at NERSC, climate scientist Michael Wehner of Berkeley Lab's Computational Research Division was able to complete a run in just three months » Read More

Quicker time to discovery. That’s what scientists focused on quantum chemistry are looking for. To achieve this, changes must be made in the HPC software used in quantum chemistry research to take advantage of advanced HPC systems to meet the research needs of scientists both today and in the future. LBL's Intel Parallel Computing Center advances are highlighted in Scientific Computing. » Read More

The past century has seen a 0.8°C (1.4°F) increase in average global temperature. What remains unclear is precisely what fraction of the observed changes in these climate-sensitive systems can confidently be attributed to human-related influences, rather than mere natural regional fluctuations in climate. In a recent Nature Climate Change paper a new method was applied to determine whether specific climate impacts can be traced to human-caused emissions. » Read More
