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’s AAIMS Group Scores Two Awards

Two different studies produced by the Analytics and AI Methods at Scale (AAIMS) group, which resides within the National Center for Computational Sciences at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory, won best paper awards at both the Bench’21 and SC21 conferences—all in the same week. On…

Digging Deep into HPC Power and Cooling

Managing a supercomputer requires operators to collect and analyze data generated from the machine itself. This data includes everything from job failure rates to power consumption figures. Researchers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) have gathered an unprecedented amount of operational data from Summit, the…

Jupyter Has Landed at the OLCF

To analyze and process scientific data, researchers often employ Jupyter notebooks, interactive web documents that host snippets of code written in statistical programming languages such as Python (or R or Julia). Domain scientists, mathematicians, data scientists, and educators use the Jupyter tool suite to analyze and visualize data, iteratively prototype codes,…

Preaching pbdR

Since bursting onto the scene in the early ’90s, high-performance computing (HPC) has become the most productive method for exploring ambitious problems in science that require substantial computational power. Yet in 2018, researchers in the statistical sciences—fields ranging from biology to economics to sociology—have yet to fully embrace the power…

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…

New Discoveries Within ‘SIGHT’

SIGHT visualization from a project led by University of Virginia’s Leonid Zhigilei to explore how lasers transform metal surface. At the home of America’s most powerful supercomputer, the Oak Ridge Leadership Computing Facility (OLCF), researchers often simulate millions or billions of dynamic atoms to study complex problems in science and…
