Abstract
Further increasing in computer performances and pooling of existing computing resources is possible with parallel and distributed work. Current directions in the development of information technologies lean significantly on the interconnection of computers in networks and clusters that already, and will even more in the future, incorporate the autonomous computing. Among other this term means that connected computers cooperate on a dynamic, reliable and safe manner. The proposed research will be focused in the design and implementation of new and efficient methods for communication and distributed computing with data acquisition and storing. Distributed protocols will be devised and tested with formal methods. Parallel algorithms, communication topologies and reliable safe communications will be investigated. Beside computer scientists, researchers from medicine, telecommunications and industry are cooperating in our group. We plane to implement various applications of parallel and distributed systems in computationally demanding computer simulations, e-business and distance learning.
Significance for science
The proposed research program has contributed new theoretical and practical results from the area of parallel and distributed processing and improving security of computer communication (and consequently information) systems. The research was focused on parallel algorithms and inter-process communication. New theoretical results have been achieved in the area of parallel algorithms, complexity analysis, fault-tolerance of processing and communication errors, and in the area of security services, infrastructure and security related human resources issues. New methods for the modeling of distributed systems were developed. Theoretical results and methods have been correlated to be useful in different application fields. Direct application results, interesting also for world wide users, have been achieved in the area of computationally intensive methods, for example heat transfer and simulation of fluid flow in medicine and molecular dynamics in chemistry. New approaches in parallel processing and simulations contribute to the personalized treatment of patients with the selection of tailored medical methods. Within molecular dynamics, new parallel algorithms enable better insight into the properties of large molecules (currently, the simulation time is limited because of the lack of computing power). Parallel computing may significantly increase the simulated interval and the number of simulated particles, in an ideal case for a factor equal to the number of available processors. Regarding the security issues, applications and services have been developed in the area of information systems security management, new security services for computer communications systems and security for emerging technologies.
Significance for the country
Investigations of distributed systems are fundamental for the development of Slovenia because they provide accesses to large databases and networked resources. This is especially meant for GRID technologies that enable a better exploitation of already existing IT infrastructure. Within this context, any respective business networked application requires appropriate security measures. Moreover, security is becoming one of the crucial strategic factors for every state, because of highly networked infrastructures. Additionally, education supported by modern computer technology is one of the mainstream approaches to permanent education that has a great priority in all societies. Slovenia has the opportunity to gain more important position with the development and research of this area, because it has relatively well-developed communication and information infrastructure. Therefore we were also focused on this area. Applicability of our research work is evident from collaboration with the Slovene national Health insurance institute in the area of health-care information systems. Besides, our research resulted in a wavelet compression module that has been developed in cooperation with the partners from industry. This is now a commercially available product in the area of video transmission. Further, in cooperation with researchers from medicine, we have developed several methods for efficient treatment and prevention of dangerous diseases. We were also focused on autonomic computing that is a long-term technological mainstream within areas of computing and information technology. Further, we anticipate that the development of computing and network technologies will initiate also the technological breakthroughs of other disciplines. For example, in the area of computer simulation, we can simulate the natural phenomena that can not be implemented by real experiments. This is the case with cooling of the human heart during heart surgery operation, where our research contributes to better outcome of such operations. Multi-channel ECG is another example of our applications that serves for more reliable determination of the place of myocardial ischemia and interpretation of electrical signals from the heart. In cooperation with the researchers from the Institute of Chemistry, we improved parallel simulation methods for molecular dynamic for investigation of the properties of large molecules, and in such a way contributed to the progress of our pharmaceutics industry. Our research results have been successfully reported on different workshops, conferences and exhibitions. The most important results were published in specialized international journals from the areas of our research, which contributed to the image of Slovenia as a country that significantly contributes to the world treasury of knowledge.
