Explicit Parallel-in-time Integration of a Linear Acoustic-Advection System
Daniel Ruprecht, Rolf Krause
The applicability of the Parareal parallel-in-time integration scheme for the solution of a linear, two-dimensional hyperbolic acoustic-advection system, which is often used as a t…
Toward fault-tolerant parallel-in-time integration with PFASST
Robert Speck, Daniel Ruprecht
We introduce and analyze different strategies for the parallel-in-time integration method PFASST to recover from hard faults and subsequent data loss. Since PFASST stores solutions…
Parareal convergence for 2D unsteady flow around a cylinder
Andreas Kreienbuehl, Arne Naegel, Daniel Ruprecht +3
In this technical report we study the convergence of Parareal for 2D incompressible flow around a cylinder for different viscosities. Two methods are used as fine integrator: backw…
Shared Memory Pipelined Parareal
Daniel Ruprecht
For the parallel-in-time integration method Parareal, pipelining can be used to hide some of the cost of the serial correction step and improve its efficiency. The paper introduces…
Time parallel gravitational collapse simulation
Andreas Kreienbuehl, Pietro Benedusi, Daniel Ruprecht +1
This article demonstrates the applicability of the parallel-in-time method Parareal to the numerical solution of the Einstein gravity equations for the spherical collapse of a mass…
Numerical simulation of skin transport using Parareal
Andreas Kreienbuehl, Arne Naegel, Daniel Ruprecht +3
In-silico investigation of skin permeation is an important but also computationally demanding problem. To resolve all scales involved in full detail will not only require exascale…
