GPREMS: Parallel Multiplicative Schwarz preconditioner for GMRES

Participants : Jocelyne Erhel, Désiré Nuentsa Wakam, Bernard Philippe [corresponding author] .

GPREMS is a numerical library for solving general linear systems on distributed memory computers. There is no assumption on the structure of the input matrix. The solver automatically performs the required permutation to distribute the data to the working processors. The solution of the linear system is iteratively found by performing several cycles of GMRES(m). This process is preconditioned at each step by one iteration of the multiplicative Schwarz method.

GPREMS was registered at APP and will be distributed with a free licence.
