Summary. The aim of this work is to reduce the development costs of new domain decomposition methods and to develop the parallel distributed software adapted to high performance computers. A new approach to development of the domain decomposition software system is suggested; it is based on the object-oriented analysis and middleware CORBA, MPI. In this paper, the main steps of domain decomposition are determined, the object-oriented framework is described, and then it is extended for parallel distributed computing. The given examples demonstrate that the software developed in such a way provides mathematical clarity and rapid implementation of the parallel algorithms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
