Largest Earthquake Simulation: Go SDSC!

SDSC Leads Supercomputing Efforts in Creating Largest-Ever Earthquake Simulation

Magnitude 8.0 Simulation, Named a Gordon Bell Prize Finalist, Could Guide Emergency Planning

Seismologists have long been asking not if, but when ‘The Big One’ will strike southern California. Just how big will it be, and how will the amount of shaking vary throughout the region? Now we may be much closer to finding out the answer to at least the latter part of that question, and help prepare the Golden State’s emergency response teams to better cope with such a potential disaster.

Software for Efficient Computing in the Age of Nanoscale Devices

San Diego, CA, August 19, 2010 -- As semiconductor manufacturers build ever smaller components, circuits and chips at the nano scale become less reliable and more expensive to produce. The variability in their behavior from device to device and over their lifetimes – due to manufacturing, aging-related wear-out, and varying operating environments – is largely ignored by today’s mainstream computer systems.
Now a visionary team of computer scientists and electrical engineers from six universities is proposing to deal with the downside of nanoscale computer components by re-thinking and enhancing the role that software can play in a new class of computing machines that are adaptive and highly energy efficient.

The National Science Foundation (NSF) today awarded a $10 million, five-year grant to researchers who will explore “Variability-Aware Software for Efficient Computing with Nanoscale Devices.” The grant is part of the funding agency’s Expeditions in Computing program, which rewards far-reaching agendas that “promise significant advances in the computing frontier and great benefit to society.”
