Abstract
The paper proposed solution to the problem of reorganization computing process after the failure of a computer system processor modules. The functioning of a multiprocessor computer system in the event of a failure of one or more processor modules is considered. It is shown that redistribution of tasks between modules and mutual control of their work allows maintaining the quality of the computing system. A dynamic algorithm for the redistribution of tasks of a multiprocessor computing system has been developed, which allows to optimize the functioning of a computing system according to the criterion of the maximum accuracy of solving work problems under restrictions on the functional power of the computing system. The proposed solution ensures the operation of the computing system after the failure of the processor modules.
