A paper describing MeshfreeFlowNet — an open-source, physics-constrained, deep-learning approach for simultaneously enhancing the spatial and temporal resolution of scientific data — is a finalist for the Best Student Paper Award at SC20.

“MeshfreeFlowNet is a big step forward in terms of physics-constrained machine learning algorithm development, combining important criteria necessary for scientific data: physics-based partial differential equation constraints, a mesh-free design that allows arbitrary resolution, scalability, and the ability to ingest data priors,” said Max Jiang, lead author on the paper and a Ph.D. student at UC Berkeley who has been affiliated with the Data Analytics Group at Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC) since 2018.

High-fidelity, high-resolution data is critical for improving our understanding of scientific phenomena and for a range of decision- and policy-making — for example, in the context of climate change. High-resolution simulations of complex systems are prohibitively expensive, and high-resolution observations and experiments often do not contain reliable information at the fine scales. To address these issues, MeshfreeFlowNet generates spatio-temporal solutions at arbitrarily high resolution from low-resolution inputs, while being computationally efficient and accurately recovering the fine-scale quantities of interest.

In early demonstrations on the GPU processors on NERSC’s Cori supercomputer, Jiang and his colleagues demonstrated that MeshfreeFlowNet can scale to up to 128 GPUs with 96.8% scaling efficiency with a training time of less than 4 minutes.

Jiang will present the research findings Tues., Nov. 17, at SC20, 11-11:30 am EST, 8-8:30 am PST.
