ACM awarded a team the Gordon Bell Prize for developing an exascale climate emulator that enhances Earth System Model outputs while reducing storage needs. This advancement addresses the computational demands of high-resolution climate models, thereby improving climate change predictions and facilitating better policy making.
The Association for Computing Machinery (ACM) has honored a 12-member team with the prestigious ACM Gordon Bell Prize for Climate Modelling in recognition of their innovative project titled “Boosting Earth System Model Outputs and Saving PetaBytes in Their Storage Using Exascale Climate Emulators.” This initiative exemplifies advancements in parallel computing tailored to address the urgent challenges posed by climate change, specifically targeting enhanced computational efficiency and data storage solutions necessary for high-resolution Earth System Models (ESMs). The team, composed of members from renowned institutions including King Abdullah University of Science and Technology and the NSF National Center for Atmospheric Research, utilized cutting-edge exascale computing capabilities to significantly improve climate change predictions.
The global climate crisis is an increasingly pressing concern, exacerbated by human activities such as fossil fuel consumption, leading to severe phenomena like intense storms, droughts, and losses in biodiversity. The use of sophisticated computational tools is vital for comprehensively understanding climate variance and developing viable strategies for mitigation. Traditionally, climate modeling has faced limitations in computational power and storage, but exascale supercomputers—capable of performing quintillions of calculations per second—are revolutionizing this field by allowing for more intricate simulations.
To overcome the inherent computational and storage challenges of high-resolution ESMs, the prize-winning team designed an exascale climate emulator that effectively streamlines data processing and storage requirements. By employing emulators, researchers can enhance the efficiency of algorithms, distribute computational loads across multiple processors, and manage vast datasets more effectively.
The significance of their emulator is highlighted by its potential to conserve several petabytes of storage—equal to the space of approximately 170 advanced servers. Their ultra-high-resolution model encompassed 54,486,360 spatial locations globally alongside extensive observational datasets. The methods used included Spherical Harmonic Transform (SHT) and Cholesky factorization, leading to a dramatic increase in spatial resolution down to approximately 3.5 kilometers.
The ACM Gordon Bell Prize for Climate Modelling was awarded at the International Conference for High Performance Computing (SC24) in Atlanta, Georgia. The achievement underscores the vital role advanced computational techniques play in climate research, policy formulation, and the broader application of machine learning methodologies for climate forecasting.
The ACM Gordon Bell Prize for Climate Modelling acknowledges significant advancements in parallel computing with the goal of combating the climate crisis. Recipients of this award demonstrate exceptional innovation and performance in computational methodologies aimed at enhancing the accuracy and efficiency of climate modeling. As global warming continues to escalate, understanding climate dynamics through sophisticated modeling techniques has become increasingly critical in informing policy and scientific research to address the profound impacts of climate change.
The recognition awarded to this pioneering team reinforces the importance of leveraging advanced computational technologies to enhance climate modeling capabilities. Their work not only addresses the pressing computational and data storage issues within the field but also holds promise for significantly improving climate prediction accuracy. As the effects of global warming intensify, innovative solutions such as the exascale climate emulator will be essential in advancing our understanding and response to climate challenges.
