Q&A with ORNL’s Bronson Messer, an HPCwire Person to Watch in 2022
August 12, 2022
HPCwire presents our interview with Bronson Messer, distinguished scientist and director of Science at the Oak Ridge Leadership Computing Facility (OLCF), ORNL, and an HPCwire 2022 Person to Watch. Messer recaps ORNL's journey to exascale and sheds light on how all the pieces line up to support the all-important science. Also covered are the role... Read more…
ORNL’s Supercomputer-Powered TRITON Tool Models Flooding
August 3, 2022
Rare, severe flooding struck both Kentucky and Missouri in the last week alone — and with climate change accelerating, such events are likely to continue. However, flood modeling remains computationally expensive. Now, researchers from Oak Ridge National Laboratory (ORNL) and Tennessee Technological University have created the TRITON toolkit, which leverages... Read more…
Summit Spins Up Research for Streamlined Carbon Fiber Production
July 1, 2022
Oak Ridge National Laboratory’s exascale Frontier system may be stealing some of the spotlight, but the lab’s 148.6 Linpack petaflops Summit system is still Read more…
US Pursues Next-gen Exascale Systems with 5-10x the Performance of Frontier
June 28, 2022
With the Linpack exaflops milestone achieved by the Frontier supercomputer at Oak Ridge National Laboratory, the United States is turning its attention to the next crop of exascale machines, some 5-10x more performant than Frontier. At least one such system is being planned for the 2025-2030 timeline, and the DOE is soliciting input from the vendor community... Read more…
At ISC, the Green500 Witnesses a New Frontier in Efficient Computing
June 8, 2022
Back in 2008, the U.S. Defense Advanced Research Projects Agency (DARPA) set an ambitious target: an exascale supercomputer in a 20-megawatt envelope. That targ Read more…
Top US Supercomputer Supports Mental Health Research
April 16, 2022
Over the course of the pandemic, the crucial role of high-performance computing and artificial intelligence in treating disease has become abundantly clear. Even as viral disease sits squarely in supercomputing’s crosshairs, however, mental illness has remained relatively foreign to the computational medicine world. Now, a collaboration between Oak Ridge National... Read more…
Summit Tackles Damaging Gas Turbine Oscillations
April 11, 2022
Natural gas-fired power plants were the largest source of electricity generation in the United States in 2020, constituting about 40 percent of the country’s power supply – and beyond electricity, gas-fired turbines power hospitals, factories and more. Unfortunately, difficult-to-predict oscillations can damage turbines over time. Now, supercomputer-powered... Read more…

End-to-End Support Toward Accelerating Discovery and Innovation with a Converged HPC and AI Supercomputer
A workload-driven system capable of running HPC/AI workloads is more important than ever. Organizations face many challenges when building a system capable of running HPC and AI workloads. There are also many complexities in system design and integration. Building a workload driven solution requires expertise and domain knowledge that organizational staff may not possess.
This paper describes how Quanta Cloud Technology (QCT), a long-time Intel® partner, developed the Taiwania 2 and Taiwania 3 supercomputers to meet the research needs of the Taiwan’s academic, industrial, and enterprise users. The Taiwan National Center for High-Performance Computing (NCHC) selected QCT for their expertise in building HPC/AI supercomputers and providing worldwide end-to-end support for solutions from system design, through integration, benchmarking and installation for end users and system integrators to ensure customer success.
