Supercomputing Dynamic Earthquake Rupture Models
Some of the world’s most powerful earthquakes involve multiple faults, and scientists are using supercomputers to better predict their behavior. Multi-fault earthquakes can span fault systems of tens to hundreds of kilometers, with ruptures propagating from one segment to the other. During the last decade, scientists have observed several cases of this complicated type of…
TACC Ranch Technology Upgrade Improves Valuable Data Storage
There’s a joke by comedian Steven Wright that goes, “You can’t have everything. Where would you put it?” Users of advanced computing can likely relate to this. The exponential growth of data poses a steep challenge to efforts for its reliable storage. For over 12 years, the Ranch system at the Texas Advanced Computing Center…
New German Supercomputer Poised to Significantly Accelerate Research
AI and High-performance Computing Extend Evolution to Superconductors
Owners of thoroughbred stallions carefully breed prizewinning horses over generations to eke out fractions of a second in million-dollar races. Materials scientists have taken a page from that playbook, turning to the power of evolution and artificial selection to develop superconductors that can transmit electric current as efficiently as possible. Perhaps counterintuitively, most applied superconductors…

Research Group Uses Supercomputing to Target the Most Promising Drug Candidates From a Daunting Number of Possibilities
Identifying the optimal drug treatment is like hitting a moving target. To stop disease, small-molecule drugs bind tightly to an important protein, blocking its effects in the body. Even approved drugs don’t usually work in all patients. And over time, infectious agents or cancer cells can mutate, rendering a once-effective drug useless. A core physical…
