by Lubomír Markovič, September 2003, 17 pages.

FIMU-RS-2003-06. Available as Postscript, PDF.


A model based on objects with roles concept is presented. It provides both theoretical and practical framework for construction of objects. In this model the objects with roles can dynamically change the interfaces they support. Some advantages of creating applications using this concept are discussed on an example of a system of virtual reality.

High Performance Computing in JAVA -- Fact or Fiction?

by Václav Dvořák, Lubomír Markovič, December 2000, 20 pages.

FIMU-RS-2000-11. Available as Postscript, PDF.


The intent of this article is to give an overview of possibilities for building distributed/parallel applications in the JAVA language and to judge the suitability of some of them for high performance computing. In the first part different approaches and libraries are presented and in the second part of this article, RMI, HORB and CORBA libraries are compared to direct communication over sockets. Gauss-Jordan algorithm for computation a system of linear equations was used to test these libraries.
