Matlab code for generating parareal stability, accuracy, and convergence regions and prototyping numerical experiments.
mains: contains all the main scripts for generating the paper figures.stability: contains all the code for calculating stability and convergence properties of IMEX integrators and parareal.stepper: contains the code for running a serial parareal algorithm that is useful for testing combinations.
Additional stability plots are located in the directory mains/grid-plots-stability/figures.
Diagrams show all coarse/fine pairings using IMEX-RK methods of orders 1 to 4 at three different zoom levels.
