Hayward Fault Earthquake Simulations Increase Fidelity of Ground Motions

Researchers at LLNL are using supercomputers to simulate the onset of earthquakes in California. “This study shows that powerful supercomputing can be used to calculate earthquake shaking on a large, regional scale with more realism than we’ve ever been able to produce before,” said Artie Rodgers, LLNL seismologist and lead author of the paper.”

Agenda Posted for April HPC User Forum in Tucson

The HPC User Forum has posted their speaker agenda for their upcoming meeting in Tucson. Hosted by Hyperion Research, the event takes place April 16-18 at Loews Ventana Canyon. “The April meeting will explore the status and prospects for quantum computing and HPC use of HPC for environmental research, especially natural disasters such as earthquakes and the recent California wildfires. As always, the meeting will also look at new developments in HPDA-AI, cloud computing and other areas of continuing interest to the HPC community. A special session will look at the growing field of processors and accelerators supporting HPC systems.”

Video: Deep Learning for Science

Prabhat from NERSC and Michael F. Wehner from LBNL gave this talk at the Intel HPC Developer Conference in Denver. “Deep Learning has revolutionized the fields of computer vision, speech recognition and control systems. Can Deep Learning (DL) work for scientific problems? This talk will explore a variety of Lawrence Berkeley National Laboratory’s applications that are currently benefiting from DL.”

Supercomputing How First Supernovae Altered Early Star Formation

Over at LBNL, Kathy Kincade writes that cosmologists are using supercomputers to study how heavy metals expelled from exploding supernovae helped the first stars in the universe regulate subsequent star formation. “In the early universe, the stars were massive and the radiation they emitted was very strong,” Chen explained. “So if you have this radiation before that star explodes and becomes a supernova, the radiation has already caused significant damage to the gas surrounding the star’s halo.”

SC17 Panel: Energy Efficiency Gains From Software

In this video from SC17 in Denver, Dan Reed moderates a panel discussion on HPC Software for Energy Efficiency. “This panel will explore what HPC software capabilities were most helpful over the past years in improving HPC system energy efficiency? It will then look forward; asking in what layers of the software stack should a priority be put on introducing energy-awareness; e.g., runtime, scheduling, applications? What is needed moving forward? Who is responsible for that forward momentum?”

Exascale Computing to Accelerate Clean Fusion Energy

In this special guest feature, Jon Bashor from LBNL writes that Exascale computing will accelerate the push toward clean fusion energy. “Turning this from a promising technology into a mainstream scientific tool depends critically on high-performance, high-fidelity modeling of complex processes that develop over a wide range of space and time scales.”

Video: Security in HPC Environments

“Modern HPC systems do some things very similar to ordinary IT computing, but they also have some significant differences. Two key security challenges are the notions that traditional security solutions often are not effective given the paramount priority of high-performance in HPC. In addition, the need to make some HPC environments as open as possible to enable broad scientific collaboration and interactive HPC also presents a challenge.”

Kathy Yelick to Keynote ACM Europe Conference

Kathy Yelick from LBNL will give the HPC keynote on Exascale computing at the upcoming ACM Europe Conference. With main themes centering on Cybersecurity and High Performance Computing, the event takes place Sept. 7-8 in Barcelona.

How Extreme Energy Jets Escape a Black Hole

Researchers are using XSEDE supercomputers to better understand the forces at work at the center of the Milky Way galaxy. The work could reveal how instabilities develop in extreme energy releases from black holes. “While nothing – not even light – can escape a black hole’s interior, the jets somehow manage to draw their energy from the black hole.”

When Neutron Stars and Black Holes Collide

Working with an international team, scientists at Berkeley Lab have developed new computer models to explore what happens when a black hole joins with a neutron star – the superdense remnant of an exploded star. “If we can follow up LIGO detections with telescopes and catch a radioactive glow, we may finally witness the birthplace of the heaviest elements in the universe,” he said. “That would answer one of the longest-standing questions in astrophysics.”
