DIRK Schemes with High Weak Stage Order
David Ketcheson, Benjamin Seibold, David Shirokoff +1
Runge-Kutta time-stepping methods in general suffer from order reduction: the observed order of convergence may be less than the formal order when applied to certain stiff problems…
More efficient time integration for Fourier pseudo-spectral DNS of incompressible turbulence
David I. Ketcheson, Mikael Mortensen, Matteo Parsani +1
Time integration of Fourier pseudo-spectral DNS is usually performed using the classical fourth-order accurate Runge--Kutta method, or other methods of second or third order, with…
CUDACLAW: A high-performance programmable GPU framework for the solution of hyperbolic PDEs
H. Gorune Ohannessian, George Turkiyyah, Aron Ahmadia +1
We present cudaclaw, a CUDA-based high performance data-parallel framework for the solution of multidimensional hyperbolic partial differential equation (PDE) systems, equations de…
