The developed DnD grid system aims to improve building of distributed computer environments by dedicated and non-dedicated resources. The proposed approach supposes overdimensioned static performance and dynamic underloading of non-dedicated resources. Efficiency, availability and autonomy of such distributed heterogeneous environment depend on platform, application, mapping and resource owner/service user (human). The developed resource management system enables creation of a ranking list of owners/users and their resources, monitoring of parameters of the established virtual organization during application execution, as well as improvement of system performance by careful mapping resources and owners/users. The obtained experimental results show that the proposed approach and the corresponding mapping algorithm can significantly improve system performance.
