Development of information technology of tasks distribution for GRID-systems using the GRASS simulation environment / T.V. Filimonchuk, M.O. Volk, I.V. Ruban, V.M. Tkachov // Eastern-European Journal of Enterprise Technologies. - Vol 3, No 9(81). - 2016. - Pp. 45-53.1729-37741729-4046http://openarchive.nure.ua/handle/document/3417An information distribution task technology for GRID-systems based on the use of simulation modeling GRASS environment was proposed. GRASS reproduces the process of functioning over time of elementary events that occur in the GRID-system with maintaining their interaction logic. This solution enables conducting of computational experiments that implement different methods of distribution, with a following selecting of the most effective solution on the basis of the collection, analysis and interpretation of simulation results. The proposed task of distribution technology using simulation modeling GRASS environment, enables implementing multiple distribution methods and selecting the best distribution environment that increases the efficiency of GRID-systems by reducing the time of the task performance and reducing the downtime of resources in highly related tasks. GRASS modeling environment has a modular structure, which consists of a core and dynamically loaded modules (plug-ins). Each module performs a highly specialized task, referring if necessary to the other modules of the system. The core provides means of inter-module interaction and provides boot and system configuration.en-USdistributed systemsGRID-system scheduler (broker)information technologyGRASS environmentcomputing resourcesallocation policyArticle
