Filimonchuk T. Methods and information technology for task distribution in heterogeneous GRID-systems

A new solution to the actual scientific and practical task of developing methods and information technology for the tasks distribution in heterogeneous GRID systems was proposed in this thesis. The object of research in the process of serving the tasks distribution in heterogeneous GRID-systems, the subject of research - planning methods and information technology tasks division in heterogeneous GRID-systems. Job distribution mathematical model for GRID system was proposed. Model used extended set of tasks and computing resources parameters and characteristics. On based model the modified Backfill method for job distribution was developed. The job distribution method with the minimum time for task pool executing and the minimal downtime of computing resources was developed. New information technology for job distribution on computer resources has been developed. This information technology is implemented in the GRASS simulation environment, that allows to reproduce the operation process in time for elementary logical events, occurring in a real GRID system with preserving interaction logic.
