Resumen
Nowadays, distributed computing is one of the popular approaches that is widely used in research and development related to the use of resource-intensive applications. The available distributed computing systems are based on modern GRID technologies. The main problem when using them, especially for heterogeneous systems, is to ensure uniform load of all nodes participating in the joint solution of the problem. This is achieved through various methods of load balancing or optimal distribution of tasks between the nodes of the computing system. The article presents the results of comparing three methods of load balancing. It has been determined that the most effective method is based on taking into account the real performance of the nodes. The results obtained can be useful to a wide range of scientific workers.
