GPREMS

Participants : Édouard Canot, Jocelyne Erhel [correspondant] , Désiré Nuentsa Wakam, Nadir Soualem.

GPREMS implements a robust hybrid solver for large sparse linear systems that combines a Krylov subspace method as accelerator with a Schwarz-based preconditioner. This preconditioner uses an explicit formulation associated to one iteration of the multiplicative Schwarz method. The Newton-basis GMRES, which aims at expressing a good data parallelism between subdomains is used as accelerator.
