Abstract
The research program ""Parallel and Distributed Systems"" is focused on parallel algorithms, communication issues in parallel computers with data security and integrity, and parallel simulations. Parallel computers, executing concurrently several operations on a set of data, have been broadening research and applications in computer science. In an effective parallel computer, parallel algorithms and communication between units are equally important for adequate performance. Within the research program we are developing new parallel algorithms for simulations in chemistry and medicine. The communication and calculation complexity of the parallel algorithms are analyzed. Some general principles for the simplification of writing and debugging of parallel programs are devised. Fault- tolerance and system diagnostic methods are studied either in parallel or distributed systems. New communication principles among parallel processors are developed and tested. In any network of processors, routing has a key impact on the effectiveness of a parallel computer. Only if the message transfer is optimal, does a parallel algorithm have the chance to be optimal. The scalable interconnection networks for parallel systems are studied. Any kind of collective communication and routing schemes in d-mesh and torus topologies are investigated to find the optimal solutions. The security services in information-communications systems, and the problem of incorporating incomplete security policy specifications at early stages of system analysis and design are studied in distributed systems. Computer simulations are often the only possible way of investigating natural phenomena. The theoretical results from the mentioned research areas are transferred into the practical environment, particularly in chemistry, medicine and communication system industry. We already implemented for example the parallel programs of force integration in molecular dynamics, and the calculation of temperature distribution on the human heart during surgery. The results of such simulations have to be tested in practice and we have developed a device for measuring bioelectrical signals i.e.: body surface potentials resulting from human heart activity.
