Decoding Atmospheric Effects of Gravity Waves

Researchers at Stanford University, the European Center for Medium-Range Weather Forecasts, or ECMWF, and Oak Ridge National Laboratory used the lab’s Summit supercomputer to better understand atmospheric gravity waves, which influence significant weather patterns that are difficult to forecast. First, the team conducted ultrahigh-resolution climate simulations using the ECMWF Integrated Forecast…

Record-Breaking Run on Frontier Sets New Bar for Simulating the Universe in the Exascale Era

The universe just got a whole lot bigger — or at least in the world of computer simulations, that is. In early November, researchers at the Department of Energy’s Argonne National Laboratory used the fastest supercomputer on the planet to run the largest astrophysical simulation of the universe ever conducted.…

Standing up the Nation’s Supercomputing Pipeline for Streaming Big Data in Real Time

Big science generates big data. But what happens when researchers produce more data than they can process? It’s actually becoming a problem for research facilities that generate so much data that only supercomputers can tackle the volume. To bridge the gap between experimental facilities and supercomputers, experts from SLAC National…

Retiring — and Shredding — the Alpine Storage System

Ever wonder what happens to massive supercomputing systems when they’re retired? Surprisingly, when it comes to the data, it’s not too different from disposing of old documents — they go straight into a shredder and sent to recycling. At the end of 2023, the Summit supercomputer — formerly the world’s…
