Record-breaking 45-qubit Quantum Computing Simulation Run at NERSC
Researchers from ETH Zurich in Switzerland used the Cori supercomputer at NERSC to simulate a 45-qubit circuit, the largest simulation of a quantum computer ever achieved. They also used the Roofline software toolkit developed in Berkeley Lab's Computational Research Division to enhance code performance. Read More »
A Fresh Math Perspective Opens New Possibilities for Computational Chemistry
A new mathematical “shortcut” developed by Berkeley Lab researchers is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours. These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year. Read More »
HPC4Mfg Paper Manufacturing Project Yields First Results
Simulations run at NERSC as part of a unique collaboration comprising Berkeley Lab, Lawrence Livermore National Laboratory and an industry consortium could help U.S. paper manufacturers significantly reduce production costs and increase energy efficiencies. Read More »

Roofline Model Boosts Manycore Code Optimization Efforts
A software toolkit developed in Berkeley Lab's Computational Research Division to better understand supercomputer performance is now being used to boost application performance for researchers running codes at NERSC and other supercomputing facilities. Read More »
Kennedy High School Students Spend ‘Amazing’ Day Learning about Berkeley Lab Computing
Twenty students and three faculty members from Kennedy High School in Richmond spent the morning of April 26 looking, listening and learning about the breadth of computing at Berkeley Lab, from desktop machines to supercomputers. The students are enrolled in the high school’s IT Academy, which includes classes on computer design, networking and web design, and integrates those subjects with classes in English, history and science. “It was amazing,” said Jaime, a junior, of the tour of the… Read More »
Recognition Software Drives Matches across Multiple Science Domains
The world is awash in images. Current estimates are that there were 2.1 billion smart phone users in mid-2016, up by half a billion since mid-2014, and they are generating a tremendous number of photos. In a perfect world, no one would store a photo without carefully annotating the place, time, and content next to the image. Of course, most of us are too busy grabbing new images to carefully curate the existing ones. The same is often true for scientists at work, who collect images without… Read More »
Rare Supernova Discovery Ushers in New Era for Cosmology
Using an automated supernova-hunting pipeline based at NERSC, astronomers have captured multiple images of a gravitationally lensed Type Ia supernova. This detection is currently the only one of its kind, but astronomers believe that if they can find more, they may be able to measure the rate of the universe’s expansion within four percent accuracy. Fortunately, two Berkeley Lab researchers have a method for identifying more of these events using existing wide-field surveys. Read More »
