SUNDIALS Multiphysics+MPIManyVector Performance Testing
Daniel R. Reynolds, David J. Gardner, Cody J. Balos +1
In this report we document performance test results on a SUNDIALS-based multiphysics demonstration application. We aim to assess the large-scale parallel performance of new capabil…
A new class of high-order methods for multirate differential equations
Vu Thai Luan, Rujeko Chinomona, Daniel R. Reynolds
This work focuses on the development of a new class of high-order accurate methods for multirate time integration of systems of ordinary differential equations. The proposed method…
Evaluation of Implicit-Explicit Additive Runge-Kutta Integrators for the HOMME-NH Dynamical Core
Christopher J. Vogl, Andrew Steyer, Daniel R. Reynolds +2
The nonhydrostatic High Order Method Modeling Environment (HOMME-NH) atmospheric dynamical core supports acoustic waves that propagate significantly faster than the advective wind…
