Modeling every building in America starts with Chattanooga

DOE/Oak Ridge National Laboratory

A team at Oak Ridge National Laboratory recently used the Oak Ridge Leadership Computing Facility's Cray XK7 Titan supercomputer to model every building serviced by the Electric Power Board of Chattanooga--all 178,368 of them--and discovered through more than 2 million simulations that EPB could potentially save $11-$35 million per year by adjusting electricity usage during peak critical times.

ORNL to host 13 teams for DOE CyberForce Competition

DOE/Oak Ridge National Laboratory

Oak Ridge National Laboratory will give college students the chance to practice cybersecurity skills in a real-world setting as a host of the Department of Energy's fifth collegiate CyberForce Competition on Nov. 16, 2019. The event brings together student teams from across the country to compete at 10 of DOE's national laboratories.

A new parallel strategy for tackling turbulence on Summit

Peer-Reviewed Publication

A Georgia Tech team developed an algorithm for simulating turbulence on Summit, the world's most powerful and smartest supercomputer. The team distributed the problem in such a way that the algorithm reached a performance of less than 15 seconds of wall-clock time per time step for more than 6 trillion grid points--a new world record surpassing the prior state of the art in the field for the size of the problem.

AI for plant breeding in an ever-changing climate

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Oak Ridge National Laboratory's Dan Jacobson is currently working on numerous projects that form an integrated roadmap for the future of AI in plant breeding and bioenergy. The team's work was featured in Trends in Biotechnology in October. In this Q&A, Jacobson talks about his team's work on a genomic selection algorithm, his vision for the future of environmental genomics, and the space where simulation meets AI.

Can a UNICORN outrun earthquakes?

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A University of Tokyo Team transformed its UNICORN computing code into an AI-like algorithm to more quickly simulate tectonic plate deformation due to a phenomenon called a "fault slip," a sudden shift that occurs at the plate boundary. The team ran UNICORN at 416 petaflops and gained a 75-fold speedup from a previous state-of-the-art solver by fully leveraging the world's most powerful and smartest supercomputer, the IBM AC922 Summit.

Obtaining order in the 'frustrated' landscape of disordered magnetism

DOE/Oak Ridge National Laboratory

Researchers from Aarhus University, Denmark, are pioneering a novel technique to solve highly elaborate magnetic structures using neutrons at the Spallation Neutron Source. Their aim is to develop the technique to establish a baseline approach that can be adapted to a broad class of magnetic materials with different structures.

Machine learning analyses help unlock secrets of stable 'supercrystal'

DOE/Oak Ridge National Laboratory

By blasting a frustrated mixture of materials with quick pulses of laser light, researchers transformed a superlattice into a supercrystal, a rare, repeating, three-dimensional structural much larger than an ordinary crystal. Using machine learning techniques, they studied the underlying structure of this sample at the nanoscale level before and after applying the laser pulse treatment.

Peer-Reviewed Publication

ORNL and NREL took demonstrated a miniaturized gyroscope. ORNL created and tested new wireless charging designs. If humankind reaches Mars this century, an ORNL-developed experiment testing advanced materials for spacecraft may play a key role. ORNL and Georgia Tech found that critical interactions between microbes and peat moss break down under warming temperatures. ORNL and industry demonstrated that an additively manufactured hot stamping die can withstand up to 25,000 usage cycles.
