We consider in this parallel algorithms called \texttt{numerical iterative algorithms} executed in a distributed environment. As their name suggests, these algorithm solves a given problem by successive iterations ($X_{n +1} = f(X_{n})$) from an initial value $X_{0}$ to find an approximate value $X^*$ of the solution with a very low residual error.

As exposed in the introduction, parallel iterative methods are now widely used in many scientific domains.
