Gordon Bell Prize Finalists Push Open Science Boundaries With NVIDIA-Powered Supercomputers

5 finalists for the Gordon Bell Prize for excellent achievements in high-performance computing (HPC) are utilizing NVIDIA-powered supercomputers for his or her vital work in local weather modeling, supplies science, fluid simulation, geophysics and digital design.

Introduced at this time at SC25the finalists’ initiatives are driving AI and HPC for science utilizing physics simulation, high-precision math and different superior supercomputing strategies, accelerating breakthroughs throughout climate forecasting, semiconductor design, house exploration and different fields. Their outcomes are open and accessible on ArXiv.

The supercomputers powering their work embrace:

• Alps — hosted on the Swiss Nationwide Supercomputing Centre (CSCS) and powered by greater than 10,000 NVIDIA GH200 Grace Hopper Superchips.
• Perlmutter — hosted on the Nationwide Power Analysis Scientific Computing Heart (NERSC) and powered by NVIDIA accelerated computing.
• JUPITER — Europe’s first exascale supercomputerhosted on the Jülich Supercomputing Centre (JSC) and powered by the NVIDIA Grace Hopper platform and Quantum-X800 InfiniBand networking.

“At CSCS, we don’t simply help open science — we speed up it,” stated Thomas Schulthess, director of CSCS. “The extraordinary breakthroughs by this yr’s 5 Gordon Bell finalists in local weather modeling, supplies science, fluid dynamics and digital twins stand as irrefutable proof: with out the Alps supercomputer, these scientific discoveries merely wouldn’t exist. Pushing computational boundaries turns daring targets into actuality, delivering scientific revolutions that may redefine our world.”

A novel configuration for the ICON Earth system mannequin — developed by researchers on the Max Planck Institute for Meteorology, German Local weather Computing Centre (DKRZ), CSCS, JSC, ETH Zurich and NVIDIA — is poised to allow extra correct climate forecasts and a deeper understanding of how the planet works.

By modeling your complete Earth’s methods at kilometer-scale decision, ICON can seize the movement of power, water and carbon by means of the environment, oceans and land with distinctive element and unprecedented temporal compression — permitting about 146 days to be simulated each 24 hours — which allows extra environment friendly local weather simulations projecting as much as a long time ahead.

“Integrating all important parts of the Earth system within the ICON mannequin at an unprecedented decision of 1 kilometer permits researchers to see full world Earth system info on native scales and study extra in regards to the implications of future warming for each individuals and ecosystems,” stated Daniel Klocke, computational infrastructure and mannequin growth group chief at Max Planck Institute for Meteorology.

Developed as a part of a collaboration between Oak Ridge Nationwide Laboratory, NVIDIA and others — and working on the Alps supercomputer — ORBIT-2 is an AI basis mannequin for climate and local weather downscaling that demonstrates unparalleled scalability and precision.

Tapping into exascale computing and algorithmic innovation, ORBIT-2 overcomes challenges confronted by conventional local weather fashions with spatial hyper-resolution downscaling, a way that creates high-resolution information from lower-resolution sources. This allows groups to seize and predict much more localized phenomena like city warmth islands, excessive precipitation occasions and refined shifts in monsoon patterns.

“NVIDIA’s superior supercomputing applied sciences enabled ORBIT-2 to realize distinctive scalability, reliability and influence on the intersection of AI and high-performance computing on NVIDIA platforms,” stated Prasanna Balaprakash, director of AI applications and part head for information and AI methods at Oak Ridge Nationwide Laboratory.

A staff from ETH Zurich has superior nanoscale digital system modeling with QuaTrEx, a bundle of algorithms that may enhance the design of next-generation transistors.

Working on the Alps supercomputer with NVIDIA GH200 Superchips, QuaTrEx can simulate units with greater than 45,000 atoms with FP64 efficiency and excessive parallel-computing effectivity. This allows sooner, extra correct design of transistors, known as NREFTs, that can be essential for the semiconductor business.

“Entry to Alps was instrumental within the growth of QuaTrEx,” stated Mathieu Luisier, full professor of computational nanoelectronics at ETH Zurich. “It allowed us to simulate units that we couldn’t think about dealing with only a few months in the past.”

Designing spacecrafts, particularly these with many small engines, requires detailed simulation, as engines packed intently collectively may cause their exhaust to work together and warmth up a rocket’s base.

Working on the Alps supercomputer, MFC, an open-source solver developed by the Georgia Institute of Know-how in collaboration with NVIDIA and others, allows fluid movement simulation 4x sooner and with over 5x larger power effectivity whereas sustaining the identical accuracy because the earlier world report. Primarily based on full-scale runs on Alps, MFC is anticipated to run at 10x the size of the earlier world report on JUPITER. This paves the best way for sooner, extra correct design of vital parts for house exploration.

“Our new info geometric regularization methodology, mixed with the NVIDIA GH200 Superchip’s unified digital reminiscence and mixed-precision capabilities, has drastically improved the effectivity of simulating advanced computational fluid flows, enabling us to simulate rocket engine plumes at unprecedented scales,” stated Spencer Bryngelson, assistant professor in computational science and engineering on the Georgia Institute of Know-how.

The College of Texas at Austin, Lawrence Livermore Nationwide Laboratory and the College of California San Diego have created the world’s first digital twin that may problem real-time probabilistic tsunami forecasts primarily based on a full-physics mannequin.

Utilized to the Cascadia subduction zone within the Pacific Northwest, the digital twin achieved advanced computations that may usually take 50 years on 512 GPUs in simply 0.2 seconds on the Alps and Perlmutter supercomputers, representing a ten billion-fold speedup.

“For the primary time, real-time sensor information could be quickly mixed with full-physics modeling and uncertainty quantification to provide individuals an opportunity to behave earlier than catastrophe strikes,” stated Omar Ghattas, professor of mechanical engineering at UT Austin. “This framework supplies a foundation for predictive, physics-based emergency-response methods throughout numerous hazards.”

For the tsunami digital twin, ICON and MFC initiatives, NVIDIA CUDA-X libraries performed a key function in maximizing the efficiency and effectivity of the advanced simulations. ICON additionally faucets into NVIDIA CUDA Graphswhich permit work to be outlined as graphs somewhat than single operations.
