Closest Type Ia Supernova in Decades Solves a Cosmic Mystery
Even as the "supernova of a generation" came into view in backyards across the northern hemisphere last August, physicists and astronomers who had caught its earliest moments were developing a surprising and much clearer picture of what happens during a titanic Type Ia explosion. Now they have announced the closest, most detailed look ever at one of the universe’s brightest “standard candles,” the celestial mileposts that led to the discovery of dark energy. Read More »
A Better Way to ID Extreme Weather Events in Climate Models
A team of researchers that includes Berkeley Lab scientists are using state-of-the-art methods in data mining and high-performance computing to quantify extreme weather phenomena in the very large datasets generated by today’s climate models. Their work will help scientists predict how climate change impact the frequency of extreme weather events. Read More »
Today’s Severe Drought, Tomorrow’s Normal
While the worst drought since the Dust Bowl of the 1930s grips Oklahoma and Texas, scientists are warning that what we consider severe drought conditions in North America today may be normal for the continent by the mid-21st century, due to a warming planet. Read More »
Supercomputers Take a Cue from Microwave Ovens
To build the break-through supercomputers that climate researchers need to model clouds, scientists are taking a cue from consumer electronics where everything from chips to batteries to software is optimized to the device’s application. Read More »

Co-Designing Exascale Architectures and Algorithms for Real-World Combustion Simulations
In a five-year project recently announced by the Department of Energy, the Combustion Exascale Co-Design Center will combine the talents of combustion scientists, mathematicians, computer scientists, and hardware architects. This multidisciplinary team will work to simultaneously redesign each aspect of the combustion simulation process—from algorithms to programming models to hardware architecture—in order to create high fidelity combustion simulations that can run at the next level of supercomputing power, the exascale.

Supercomputer Cracks "Impossible" Calculation
David Bailey
Australian researchers have done the impossible—they’ve found the sixty-trillionth binary digit of Pi-squared! The calculation would have taken a single computer processor unit (CPU) 1,500 years to calculate, but scientists from IBM and the University of Newcastle managed to complete this work in just a few… Read More »
