Exascale Earth-modeling system is ready to make high-fidelity predictions for energy

ALBUQUERQUE, N.M. — An Earth modeling system developed over the last four years and unveiled Monday is expected to have one of the finest resolutions ever achieved by supercomputers simulating aspects of the planet’s climate, said Sandia National Laboratories researcher Mark Taylor, the project’s chief computational scientist. The Energy Exascale Earth System Model, E3SM, is […]

Using biomimicry to detect outbreaks faster

ALBUQUERQUE, N.M. — Our immune systems are made up of billions of white blood cells searching for signs of infections and foreign invaders, ready to raise the alarm. Sandia National Laboratories computer scientists Pat Finley and Drew Levin have been working to improve the U.S. biosurveillance system that alerts authorities to disease outbreaks by mimicking […]

Supercomputing under a new lens: A Sandia-developed benchmark re-ranks top computers

ALBUQUERQUE, N.M. — A Sandia National Laboratories software program now installed as an additional test for the widely observed TOP500 supercomputer challenge has become increasingly prominent. The program’s full name — High Performance Conjugate Gradients, or HPCG — doesn’t come trippingly to the tongue, but word is seeping out that this relatively new benchmarking program […]

Blast, impact simulations could lead to better understanding of injuries and body armor

ALBUQUERQUE, N.M. — Sandia National Laboratories is developing specialized computer modeling and simulation methods to better understand how blasts on a battlefield could lead to traumatic brain injury and injuries to vital organs, like the heart and lungs. Researchers at Sandia have studied the mechanisms behind traumatic brain injury for about a decade. Their traumatic […]

Sandia computer modeling aids solder reliability in nuclear weapons

ALBUQUERQUE, N.M. — Solder isn’t the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability. “Computational modeling of solder joint fatigue […]

HADES creates alternate reality to mislead hackers

 ALBUQUERQUE, N.M. —The Russian novelist Fyodor Dostoevsky once postulated that the devil no longer uses fire and brimstone but instead simply tells you what you want to hear. Sandia National Laboratories cyber researchers go with that second option when it comes to foiling a hacker. Rather than simply blocking a discovered intruder, Vince Urias, Will […]

Diagnosing supercomputer problems

Sandia, Boston University win award for using machine learning to detect issues ALBUQUERQUE, N.M. — A team of computer scientists and engineers from Sandia National Laboratories and Boston University recently received a prestigious award at the International Supercomputing conference for their paper on automatically diagnosing problems in supercomputers. The research, which is in the early […]

Sandia researcher receives IEEE Computer Society’s 2017 Sidney Fernbach Award

ALBUQUERQUE, N.M. — Steve Plimpton, a computational scientist at Sandia National Laboratories’ Center for Computing Research, has received the IEEE Computer Society’s 2017 Sidney Fernbach Award for “high-performance computer simulation frameworks that have advanced research in materials science, chemistry, biology and other related areas.” The citation, while accurate in scope, hardly portrays the depth of […]

Sandia computing researcher wins DOE Early Career Research Program Award

ALBUQUERQUE, N.M. — Sandia National Laboratories researcher Tim Wildey has received a 2017 Early Career Research Program award from the Department of Energy’s Office of Science. Wildey is Sandia’s first winner of the Advanced Scientific Computing Research branch of the prestigious program, said manager Daniel Turner. The national award, now in its eighth year, provides […]

Sandia Labs researcher wins national award in computational fluid dynamics

ALBUQUERQUE, N.M. — Sandia National Laboratories researcher Pavel Bochev has been awarded the Thomas J.R. Hughes Medal by the U.S. Association for Computational Mechanics. The award is given biannually for “outstanding and sustained contributions to the broad field of computation fluid dynamics.” Sandia manager Michael Parks said Bochev was chosen specifically for “foundational contributions to […]
