The work described in this dissertation concerns developer oriented method that facilitates estimation of efficiency of applications designed for distributed environment, with special attention payed to the Grid. The method enables developers to describe their concepts of applications and exploited resources on high level of abstraction, enabling convenient analysis, if necessary on early stages of development. The model is then automatically transformed to the formalism of Timed Colored Petri Net (TCPN), being capable of reliable reflection of activities that appear in distributed systems. Precision of estimation is ensured by the formalism of TCPN supported by specialized external modules that model network-related issues and can be easily swapped. Reliability of the method was verified on the basis of prototype implementation by comparison of results obtained from simulations and real-world experiments. The results showed that the method is capable of providing valuable estimations. The main contribution of this research is the simulation method described above and combining virtues of analysis based on a formalism and supported by specialized modules, with convenience and rapid modeling. Additionally, the thesis describes solutions for several well-defined scientific and technical problems that were encountered while the research and may be useful in the other works.

Zarządzanie zasobami gridowymi z użyciem parawirtualizacji

Most of current works concerning the optimalization of resource management mechanisms in Grid environments, concentrate on assuring similar functionality at the middleware layer. Hence of some restrictions in such resource allocation and management, this dissertation proposes the usage of virtualization techniques as a light mechanism enabling the control of resource utilization. The practical verification of the implementation of the proposed concept will enable to effectively manage the Virtual Grid built with components consisting of emulated (virtual) machines. Basing the Grid environment on virtualization would allow the flexible reconfiguration of particular nodes and through the migration of virtual machines to effectively use the pool of physical machines without stopping running components. The aim of this work was also to verify whether the concept of mapping the application to the execution environment (called Virtual Grid) and tailored to its requirement is an effective way of available resources allocation.
