Cosmic rays—accelerated atomic nuclei driven by astrophysical phenomena—provide ways to study how galaxies evolved. Using exascale computing power and an #INCITE award researchers are modeling both large- and small-scale behavior in these systems and developing a new model that accounts for unexplained turbulence. https://ascr-discovery.org/2025/02/untangling-the-cosmos/ #HPC #OLCF #ALCF

Simulations to study new ways to catalyze hydrogen production could help with energy storage. Harvard University's Boris Kozinsky and his team are using machine learning to accelerate these complex calculations. https://ascr-discovery.org/2025/01/carbon-free-hydrogen/ Their #INCITE award includes allocations at both #ALCF and #OLCF. #HPC

The human brain's trillions of connections remain largely uncharted. But a team from Argonne National Laboratory and Harvard University is using advanced electron microscopy and #ALCF's hardware and machine learning tools to map neurons' links to better understand how they interact https://ascr-discovery.org/2024/12/connecting-the-neurodots/ #HPC

As large language models get bigger, they're increasingly difficult to train. But a team led by Abhinav Bhatele of University of Maryland has developed the open-source #AI training framework, AxoNN, which distributes the work across multiple GPUs. https://ascr-discovery.org/2024/11/we-the-ai-trainers/ The work is nominated for a 2024 ACM, Gordon Bell Prize at #SC24 and has been supported by an #INCITE allocation at #OLCF and #ALCF.

Lithium-ion batteries rely on stable, functional electrolytes to store energy. The University of Michigan's Venkat Viswanathan is leading a team building a foundation model to design better electrolyte recipes that could be useful for many chemistry applications. https://ascr-discovery.org/2024/10/ai-turbocharge/ #HPC #renewableenergy #ALCF #LLM

During the pandemic, Margaret Cheung pivoted to a career modeling the molecular mechanisms of disease transmission at Pacific Northwest National Laboratory. Using a digital twin of the process, she's helping to grapple with complex biological data and find new strategies to disrupt infections. https://ascr-discovery.org/2024/10/pandemic-preparedness/ #HPC #OLCF #ALCF #NERSC

To build #quantum computers, we'll need ways to manufacture #chips. Aiichiro Nakano and his
