How many supercomputers does it take to simulate plasma turbulence? Quite a few, it turns out. Researchers from the University of Wisconsin-Madison (UW) utilized a number of ACCESS resources, including Stampede2 from the Texas Advanced Computing Center (TACC), Expanse from the San Diego Computing Center (SDSC) and Bridges-2 from the Pittsburgh Supercomputing Center (PSC). But […]

This past year at SC24, there was a marked increase in liquid cooling companies. The term “liquid cooling” describes moving system heat through water rather than air. Moving water is much more complicated than moving ambient air but can hold much more heat by volume than air. Air is lighter and does not spill, but […]

The meteoric rise of DeepSeek R-1 has put the spotlight on an emerging type of AI model called a reasoning model. As generative AI applications move beyond conversational interfaces, reasoning models are likely to grow in capability and use, which is why they should be on your AI radar. The post What Are Reasoning Models […]

For the first time, a team of researchers at Lawrence Livermore National Laboratory (LLNL) quantified and rigorously studied the effect of metal strength on accurately modeling coupled metal/high explosive (HE) experiments, shedding light on an elusive variable in an important model for national security and defense applications. The post LLNL Researchers Quantify Metal Strength Uncertainty […]

HPCwire, the leading publication for news and information for the high performance computing industry, today unveiled its People to Watch for 2025. This feature highlights key community members who are driving the industry forward, people you should be keeping an eye on in the year to come. The post HPCwire Unveils 2025 People to Watch […]

In a milestone that brings quantum computing tangibly closer to large-scale practical use, scientists at Oxford University’s Department of Physics have demonstrated the first instance of distributed quantum computing. Using a photonic network interface, they successfully linked two separate quantum processors to form a single, fully connected quantum computer, paving the way to tackling computational […]

A recent study led by quantum researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) proved popular among the science community interested in building a more reliable quantum network. The post Researchers Develop First-of-Its-Kind Quantum Gate for Enhanced Communication appeared first on HPCwire.

Aside from making GPUs scarce and expensive (even in the cloud), these rapid changes have suggested many questions in the HPC community. The post Feeding the Virtuous Cycle of Discovery: HPC, Big Data, and AI Acceleration appeared first on HPCwire.

Google expects to bring commercial quantum computing applications to market within five years, according to Hartmut Neven, Google VP of Engineering and longtime leader of its quantum research efforts. Speaking to Reuters on Wednesday, Neven’s projection contrasts with Nvidia CEO Jensen Huang’s recent estimate that practical quantum computing is still two decades away. The post […]

Data centers are significant consumers of global electricity, with their share expected to rise in the coming years. In 2022, data centers consumed approximately 460 terawatt-hours (TWh) of electricity, accounting for about 2% of global electricity usage. Projections indicate that by 2026, this consumption could increase to between 650 TWh and 1,050 TWh, potentially representing […]
