This article analyzes the parallel scalability of the WILDFIRES-IGA-ADS simulator on a concurrent server with shared memory and employs the isogeometric finite element method with tensor product B-spline basis functions, explicit time integration schemes, and a linear computational cost solver resulting from the Kronecker product structure of the mass matrix.
An orthogonal 4D-parallelization scheme is devised that introduces a unique domain-tensor-parallelism strategy and a novel uncertainty parallel method, enabling the potential of high-fidelity uncertainty quantification in atmospheric AI models, heralding a new era for AI-based models in climate and Earth system science...

To the authors' knowledge, FESOM2-JAX is the first global ocean-sea-ice model of CMIP-class complexity written natively in a differentiable framework, and the first on an unstructured mesh.

A new prolongator filtering, a new PETSc GAMG algorithm that drops small blocks from the coarse space under a Frobenius criterion with a kernel-preserving projection, and a new PETSc GAMG algorithm that reduces P^TAP traffic, coarse-operator fill, and memory, and cuts the hot time on the fine grid with iteration counts...
An implementation of the Physiological Processes Predicting Growth (3-PG) model in JAX that uses just-in-time compilation, vectorization, and GPU acceleration to reduce execution time and enables efficient gradient-based optimization and gradient-informed Bayesian calibration.

A contiguous cartogram is a map whose area is proportional to a quantity such as population. The defining condition, that the Jacobian determinant of the deformation equals the density, is one equation for two unknown functions, so every cartogram method adds a tie-breaker, usually implicitly. Optimal transport makes t...
The lattice Boltzmann method (LBM) is a well-established approach for simulating fluid flows at the mesoscopic scale. With the stagnation of Moore's law, high-performance computing has shifted toward GPU accelerators, necessitating programming models that ensure both portability and efficiency across diverse hardware p...
