Leveraging Deep Operator Networks (DeepONet) for Acoustic Full Waveform Inversion (FWI)
Kamaljyoti Nath, Khemraj Shukla, Victor C. Tsai +6
Full Waveform Inversion (FWI) is an important geophysical technique considered in subsurface property prediction. It solves the inverse problem of predicting high-resolution Earth…
GPU performance analysis of a nodal discontinuous Galerkin method for acoustic and elastic models
Axel Modave, Amik St-Cyr, Tim Warburton
Finite element schemes based on discontinuous Galerkin methods possess features amenable to massively parallel computing accelerated with general purpose graphics processing units…
Nodal Discontinuous Galerkin Simulations for Reverse-Time Migration on GPU Clusters
Axel Modave, Amik St-Cyr, Wim A. Mulder +1
Improving both accuracy and computational performance of numerical tools is a major challenge for seismic imaging and generally requires specialized implementations to make full us…
High-Order Finite-differences on multi-threaded architectures using OCCA
David S. Medina, Amik St-Cyr, Timothy Warburton
High-order finite-difference methods are commonly used in wave propagators for industrial subsurface imaging algorithms. Computational aspects of the reduced linear elastic vertica…
OCCA: A unified approach to multi-threading languages
David S Medina, Amik St-Cyr, T. Warburton
The inability to predict lasting languages and architectures led us to develop OCCA, a C++ library focused on host-device interaction. Using run-time compilation and macro expansio…
Optimized Schwarz preconditioning for SEM based magnetohydrodynamics
Amik St-Cyr, Duane Rosenberg, Sang Dong Kim
A recent theoretical result on optimized Schwarz algorithms demonstrated at the algebraic level enables the modification of an existing Schwarz procedure to its optimized counterpa…
Multiplicative, Additive and Restricted Additive Optimized Schwarz Preconditioning
Amik St-Cyr, Martin J. Gander, Stephen J. Thomas
We demonstrate that a small modification of the multiplicative, additive and restricted additive Schwarz preconditioner at the algebraic level, motivated by optimized Schwarz metho…
A Comparison of Two Shallow Water Models with Non-Conforming Adaptive Grids: classical tests
Amik St-Cyr, Christiane Jablonowski, John M. Dennis +2
In an effort to study the applicability of adaptive mesh refinement (AMR) techniques to atmospheric models an interpolation-based spectral element shallow water model on a cubed-sp…
