The paper "Exponential Integrators with Parallel-in-Time Rational Approximations for Shallow-Water Equations on the Rotating Sphere" was published in the Journal of Parallel Computing.
Exploiting the upcoming massively parallel compute performance of Exascale computers requires a rethinking for solving partial differential equations.
The paper "Exponential Integrators with Parallel-in-Time Rational Approximations for Shallow-Water Equations on the Rotating Sphere" by Martin Schreiber (CAPS/TUM),Nathanael Schaeffer (CNRS / Univ. Grenoble Alpes) and Richard Loft (CISL/NCAR) was recently published.
Here, the authors present significant wallclocktime-to-error improvements for single-layer atmospheric models by using Cauchy contour methods to time-integrate climate and weather simulations in such a massively parallel fashion.
