Center for Computing Research

The Center for Computing Research (CCR) at Sandia creates technology and solutions for many of our nation's most demanding national security challenges. The Center's portfolio spans the spectrum from fundamental research to state‑of‑the‑art applications. Our work includes computer system architecture (both hardware and software); enabling technology for modeling physical and engineering systems; and research in discrete mathematics, data analytics, cognitive modeling, and decision support materials.

    Warren Davis Earns National Honors in Leadership and Technology

    Warren Davis, received his award during the conference in Washington, D.C., Feb. 7-9, 2019. The annual meeting recognizes black scientists and engineers and is a program of the national Career Communications Group, which advocates for corporate diversity.

    This scientist wants to help you see like a computer.

    If you saw all the aquariums that fill Davis’ home, you might think he was a pet lover. But you’d be wrong.  Davis just has a passion for recreating things.

    “I’ve got a sand bed that does denitrification in a certain layer,” mimicking a natural aquatic ecosystem, Davis said. “I’ve got animals that sift the sand bed so it doesn’t become anoxic. I have things that eat uneaten food particles that get trapped under the rocks.” It’s not a perfect model, he said, but it’s close.

    Davis is also adept at recreating natural, mechanical processes to solve problems in engineering. In these cases, he takes natural phenomena — like air flowing over a surface or a person taking a step — and uses machine learning to explain them mathematically with an equation, also called a function. Machine learning can approximate complex processes much faster than they can be numerically solved, which saves companies time and resources if, for example, they want to predict how well a proposed aircraft design would hold up in flight. These savings compound when designers want to simulate multiple iterations.

    “That’s what I do. I try to learn the functions that we care about,” Davis said.

    He also has taken a leadership role helping Sandia and its business partners incorporate machine learning into their own research and development programs. On multiple occasions, he says, this addition has transformed the way they work, making their research more efficient and agile long after his project with them has ended.

    The technique sometimes delivers unexpected solutions, too.

    “When I’m able to take a data set and come up with something people haven’t seen before or some underlying function it is truly an amazing, almost magical feeling,” he said.

    Davis’ work earned him a Research Leadership award.

    Kokkos User Group Meeting

    The Kokkos team is announcing the first Kokkos User Group Meeting to be held in Albuquerque New Mexico, USA April 23rd through 25th. The meeting will give the growing Kokkos community a chance to present progress in adopting Kokkos, exchange experiences, discuss challenges and help set priorities for the future roadmap of Kokkos. Projects are invited to give a 20 minute presentation. Application talks are encouraged to focus on technical and algorithmic challenges in adopting Kokkos and how Kokkos’s capabilities were used to overcome those.
