May 16, 2022

The Department of Energy's Oak Ridge National Laboratory (ORNL) has selected Doug Kothe to be the next Associate Laboratory Director for its Computing and Computational Sciences Directorate (CCSD), HPCwire has learned. Kothe will fill the vacancy created by the retirement of Jeff Nichols, whose last day is July 1. Kothe will transition into the position on June 6. As director of the United States' Exascale Computing Project... Read more…

Summit Simulations Illuminate Important Uranium Compound

May 7, 2022

Uranium tetrafluoride hydrate (UFH) is produced as a byproduct during the fuel cycle for nuclear power plants—but it remains poorly understood in comparison t 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…

Ahead of Frontier’s Deployment This Year, 1.5 Cabinet ‘Crusher’ Serves Science

March 28, 2022

The Frontier supercomputer was installed at Department of Energy’s Oak Ridge National Laboratory in 2021, with the final cabinet rolled into place in October. While shakeout of the full 2-exaflops peak system continues – we have heard off-record about troubles with the fabric technology that connects the massive system – the Frontier project is running with a smaller testbed system of the same core design.

Whitepaper

5 HPC Optimization Techniques

For many organizations, decisions about whether to run HPC workloads in the cloud or in on-premises datacenters are less all-encompassing and more about leveraging both infrastructures strategically to optimize HPC workloads across hybrid environments. From multi-clouds to on-premises, dark, edge, and point of presence (PoP) datacenters, data comes from all directions and in all forms while HPC workloads run in every dimension of modern datacenter schemes. HPC has become multi-dimensional and must be managed as such.

This white paper explores several of these new strategies and tools for optimizing HPC workloads across all dimensions to achieve breakthrough results in Microsoft Azure.
