Abstract:
When using redundant computer systems in mission-critical information- measuring and control systems of high availability the significant indicators of whole system efficiency are the preserving of the integrity of data sets and processing results under the short-term failures and refusals, and providing of the guaranteed minimum time of information exchange between computing modules, but herewith the algorithm of interaction between computing modules is not obvious. Based on the analysis of the graphs of the state of two-machine computer system the article presents the developed algorithms of in-teraction between computing modules in two-machine computing system to reduce loss of the computing system performance and providing the data integrity in case of failures in case of the different modes data exchange between complex-s computing modules, that guarantees the additional possibility of providing information and functional safety, resiliency and survivability of computer system.
