One Multiprocessor Realization of an Iteration Algorithm for System with Different Memory
AbstractSome multiprocessors realizations of the α–β-iteration algorithm for solution of five-dots difference equations systems are considered.
One Variant of Semi-Coarsening Multigrid Method
AbstractA variant of multigrid method for solving large systems of linear equations with block tridiagonal matrices that have higher robustness properties is presented.In this method the construction of coarse grid correction operators is based on approximation of the Schur complement. Numerical experiments show high efficiency of presented methods.
