Goodbye HPSS, Hello Kronos

Users of the Oak Ridge Leadership Computing Facility are experiencing big changes with how their data is stored — in a good way. As the OLCF’s High Performance Storage System is to be decommissioned in early 2025 after decades of service, users are becoming familiar with Kronos, which is already proving its ease of use and…

Exascale’s New Frontier: GAMESS

In 2016, the Department of Energy’s Exascale Computing Project, or ECP, set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That meant rethinking, reinventing and optimizing dozens of scientific applications and software tools to leverage exascale’s thousandfold…

Flying Quieter and Cleaner

From a nondescript industrial building in the small town of Crossville, Tennessee, the team of engineers at Whisper Aero is planning a revolution in aviation technology. Previously home to a publisher of magazines — including, coincidentally, Trade-A-Plane, an airplane sales publication started in 1937 — the long-empty property’s cavernous spaces…

Frontier Simulations Could Help Build a Better Diamond

The world’s fastest supercomputer helped researchers simulate synthesizing a material harder and tougher than diamond — or any other substance on Earth. The study used Frontier, the HPE Cray EX supercomputing system at the Department of Energy’s Oak Ridge National Laboratory, to predict the likeliest strategy to synthesize such a…
