The objective of this work is to contribute to the resolution of the large eigenproblems and/or the large linear systems by using shared resources on more or less large scale networks. The resolution of large systems in linear algebra is carried out, using the hybrid iterative methods. A hybrid method combines several different numerical methods or several copy of the same numerical method parameterized differently in order to accelerate the convergence of one of the methods. The convergence acceleration of hybrid methods by the numerical methodologies and/or parallel and distributed techniques constitutes the principal objective of this thesis. The acceleration convergence of these methods is dependent on the used restarting strategy. A st...
