Gordon Bell Prizes Awarded at SC25 Conference
November 20, 2025
An eight-member team drawn from US institutions is the winner of the 2025 ACM Gordon Bell Prize for their project, “Real-Time Bayesian Inference at Extreme Scale: A Digital Twin for Tsunami Early Warning Applied to the Cascadia Subduction Zone.” Existing state-of-the art high-performance computing simulations for early tsunami warning do not allow for enough warning time and fail to capture the complexities of earthquake ruptures which cause the Tsunamis. The Gordon Bell Prize-winning team creates a far more predictive early warning framework by developing a full-physics Bayesian inversion framework enabling real-time, data-driven tsunami forecasting with dynamic adaptivity to complex source behavior.
This year an Honorable Mention for the ACM Gordon Bell Prize was given to a 10-member team from ETH Zurich for their project “Ab-Initio Quantum Transport with the GW Approximation, 42,240 Atoms, and Sustained Exascale Performance.”
The ACM Gordon Bell Prize tracks the progress of parallel computing and rewards innovation in applying high-performance computing to challenges in science, engineering, and large-scale data analytics.
ACM also presented a 26-member team with the 2025 ACM Gordon Bell Prize for Climate Modelling in recognition of their project “Computing the Full Earth System at 1 km Resolution.” Among the most effective tools scientists have developed to understand climate change are digital simulations of the Earth. The Gordon Bell Climate Prize-winning team reached a landmark this year by being the first team ever to develop a Full Earth Simulation at 1 km (extremely high) Resolution.
The ACM Gordon Bell Prize for Climate Modelling honors innovative parallel computing contributions toward solving the global climate crisis.
Both awards were presented earlier today during the International Conference for High Performance Computing, Networking, Storage and Analysis (SC25) in St. Louis, Missouri.
