Abstract
The practical aspect of the parareal algorithm that consists of using two solvers the coarse and fine over different time stepping to produce a rapid convergent iterative method for multi processors computations. The coarse solver solve the equation sequentially on the coarse time step while the fine solver use the information from the coarse solution to solve, in parallel, over the fine time steps.
