Adaptable IO System Delivers the Data

Amid the challenges that the Department of Energy’s Oak Ridge Leadership Computing Facility faced in assembling and launching the world’s first exascale-class (more than a quintillion calculations per second) supercomputer, Frontier, one key component was hitch-free. Integral to Frontier’s functionality is its ability to store the vast amounts of data…

ORNL Security Teams Prepare to Take the Heat with Cyber Fire

The high-performance computing (HPC) cybersecurity engineers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) typically face small cybersecurity incidents, so they don’t often get a chance to respond to bigger events. Cyber Fire is a program that offers multiple cybersecurity training events to staff members at…
