Abstract. The problem of managing a specialized cloud computing system performing heterogeneous resource-intensive tasks is considered when methods of the task execution can be represented as an arbitrary sorting out of a large number of options. Data-based parallelization of tasks under uncertainty is analyzed. To solve the problems of scheduling incoming input streams of tasks, the simulation is performed using the SimEvent/Simulink/MatLab software package. The functioning of the system and especially servers, represented as finite state machines, is analyzed. The peculiarity of the proposed model is the possibility of interrupting the server when an external signal appears. Using the developed server model makes it possible to improve system performance by saving time for each server to complete tasks and more efficiently distributing tasks between the servers of the entire system.
