Computer models and simulations play a central role in the study of complex systems in engineering, life sciences, medicine, chemistry, and physics. Utilizing modern supercomputers to run models and simulations allows for experimentation in virtual laboratories, thus ... Weblems in a time-parallel fashion. Already in 1964, Nievergelt suggested a parallel time-integration algorithm [24], which eventually developed into the multiple shoot-ing method for boundary value problems; see [16]. The idea is to decompose the time-integration interval into subintervals, to solve an initial value problem on each

The paper introduces a basic OpenMP implementation of pipelined Parareal and compares it to a standard MPI-based variant.

In contrast to e.g. Runge-Kutta or multi-step methods, some of the computations in Parareal can be performed in parallel and Parareal is therefore one example of a parallel-in-time integration method. While historically most efforts to parallelize the numerical solution of partial differential equations focussed on the spatial discretization, in view of the challenges from exascale computing, parallel methods for temporal discretization have been identified as a possible way to increase …
