Finite-Budget Convergence and Chaos-Aware Stopping Criteria for Time-Parallel Methods
Giancarlo Antonino Antonucci, Raphael Andreas Hauser, Debasmita Samaddar +1
Time-parallel algorithms, such as Parareal, are well understood for linear problems, but their convergence analysis for nonlinear, chaotic systems remains limited. This paper intro…

Stochastic parareal: an application of probabilistic methods to time-parallelisation
Kamran Pentland, Massimiliano Tamborrino, D. Samaddar +1
Parareal is a well-studied algorithm for numerically integrating systems of time-dependent differential equations by parallelising the temporal domain. Given approximate initial va…
