An hybrid approach for the parallelization of a block iterative algorithm
Balsa, Carlos; Guivarch, Ronan; Ruiz, Daniel; Zenadi, MohamedThe Cimmino method is a row projection method in which the original linear system is divided into subsystems. At every iteration, it computes one projection per subsystem and uses these projections to construct an approximation to the solution of the linear system. The usual parallelization strategy in block algorithms is to distribute the different blocks on the available processors. In this paper, we follow a...
MUMPS based approach to parallelize the block cimmino algorithm
Balsa, Carlos; Guivarch, Ronan; Raimundo, João; Ruiz, DanielThe Cimmino method is a row projection method in which the original linear system is divided into subsystems. At every iteration, it computes one projection per subsystem and uses these projections to construct an approximation to the solution of the linear system. The usual parallelization strategy applied in block algorithms is to distribute the different blocks on the different available processors. In this ...
