OLCF Reaches New Heights with Andes Cluster

Staff members at the Oak Ridge Leadership Computing Facility (OLCF) have replaced the center’s Rhea data analysis cluster with a brand-new AMD-based system dubbed Andes. For 6 faithful years, Rhea afforded OLCF users the opportunity to perform data analysis and visualizations of simulations performed on the OLCF’s former Cray XK7…

ORNL Scientists Tap into AI to Put a New Spin on Neutron Experiments

Scientists seek to use quantum materials—those that have correlated order at the subatomic level—for electronic devices, quantum computers, and superconductors. Quantum materials owe many of their properties to the physics that is occurring on the smallest scales, physics that is fully quantum mechanical. Some materials, such as complex magnetic materials,…

Titan Powers Data Dive into Tropical Soil Microbes

Using high-performance computing, an Oak Ridge National Laboratory-led research team analyzed how the availability of phosphorous affects microbes’ foraging strategies in a tropical ecosystem. At right, microbial genes encode the production of phytase enzymes that break apart phytate molecules, releasing much needed phosphate for the microbes’ survival. Every life-form depends…

Seeing Is Believing

When the Oak Ridge Leadership Computing Facility upgraded its Jaguar supercomputer to the Cray XK7 CPU/GPU hybrid system known as Titan, the center knew that upgrades to its data analysis and visualization resources were necessary to complement Titan’s more than 20 petaflops of computing power.
