摘要: Domain decomposition ideas have long been an essential tool for the solution of PDEs on parallel computers. In recent years many research efforts focused recursively employing domain methods to obtain multilevel preconditioners be used with Krylov solvers. this context, we developed MLD2P4 (MultiLevel Decomposition Parallel Preconditioners Package based PSBLAS), a package that combines additive Schwarz smoothed aggregation technique build hierarchy coarse-level corrections in algebraic way. The design was guided by objectives such as extensibility, flexibility, performance, portability, and ease use. They were achieved following object-based approach while using Fortran 95 language, well PSBLAS library basic framework. article, present focusing its principles, software architecture,
