Recent observations from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy may be evolving over time — a potential discovery that could transform our understanding of the universe. To investigate this possibility, Argonne National Laboratory researchers used the ALCF’s Aurora exascale supercomputer to perform high-resolution simulations of the universe's evolution, providing a test bed for the broader community to refine analysis methods and explore whether the DESI findings point to new physics beyond the standard model of cosmology.

Learn strategies for overcoming challenges in memory management, execution models, and optimizing code for Aurora’s advanced architecture. Register here: https://lnkd.in/g3KYaBvM

Congratulations to ALCF Director Michael Papka on being named an Argonne Distinguished Fellow, Argonne National Laboratory's highest scientific and engineering rank! Over his 35-year career at Argonne, Papka has played a pivotal role in advancing computing research, leading the ALCF and serving as a senior scientist and deputy associate laboratory director for Computing, Environment, and Life Sciences.   https://lnkd.in/gtj8WHCr

NASA - National Aeronautics and Space Administration's Nancy Grace Roman Space Telescope and the NSF-DOE Rubin Observatory will soon expand our understanding of the cosmos, and scientists are getting a head start using supercomputers at Argonne National Laboratory. The team leveraged ALCF computing resources to simulate nearly 4 million images of how these telescopes will observe the universe, helping researchers prepare for the vast datasets they will produce and offering an early look at how they will explore dark matter, dark energy, and galaxy evolution. “We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing every photon’s path all the way from each cosmic object to Roman’s detectors. This is the largest, deepest, most realistic synthetic survey of a mock universe available today.” - Michael Troxel of Duke University https://lnkd.in/g4qs99yE Visualization: NASA’s Goddard Space Flight Center and M.

From accelerating cancer research and materials discovery to advancing our understanding of the cosmos and fusion energy, Argonne National Laboratory's Aurora exascale supercomputer is providing scientists with powerful simulation, AI, and data analysis capabilities to push the boundaries of discovery and innovation.    https://lnkd.in/gExKTAQn #HPC #AI #exascale #supercomputing

It’s not a conference, it’s a jam! Last month, Argonne co-hosted the first-ever 1,000 Scientist AI Jam. The event convened 1,500 scientists across the U.S. Department of Energy (DOE)’s national laboratories to push the boundaries of AI-driven discovery and maintain U.S. leadership in AI - https://bit.ly/4kN9tZh Scientists worked independently and in small groups, bringing specialized scientific problems to evaluate the capabilities of AI models from OpenAI and Anthropic. This hands-on approach allowed scientists to assess the performance of AI in solving complex challenges and provided valuable data on model efficacy across a range of scientific tasks.
