Parareal

Parareal is a parallel algorithm designed for solving time-dependent partial differential equations (PDEs). The primary goal of Parareal is to accelerate the simulation time of these equations, which are often computationally expensive to solve, especially when high accuracy is required over long time intervals. The basic idea behind the Parareal algorithm involves dividing the time domain into smaller intervals and solving the problem in a coarse fashion using a low-resolution method (a "coarse solver").
