Abstract :
This work describes the use of a solver with a modified LU preconditioner using an additional intersection parameter among the blocks in order to minimize the weakness due to the blocks decoupling. The LU preconditioning is tested on a cluster computer linked by a Gigabit switch. The program uses SPMD model and MPI library
