Implementace distribuovaných datových struktur do knihovny OOSol

Abstract

This thesis deals with implementation of distributed data structures in OOSol library utilizing existing data structures and algorithms using object oriented middleware CORBA. Basic aspects of CORBA technology are described, as well as its use for implementation of distributed storage of block and diagonal block matrices on a large number of processors. Furthermore, implementation of basic operations on distributed matrices are described, which allow parallel computation using existing algorithms, e.g. conjugate gradient method. Testing on model problems is included, which shows the speed and scalability of this implementation. Also, a comparsion of CORBA with MPI is made.
