Creating a reliable computer systems with a high degree of readiness involves the introduction into the structure of complex hardware and software redundancy (automaton of intercomputer control and recovery, consisting of the control exchange unit and control reconfiguration device), which in turn causes a decrease in performance computing complex. The article details the analysis of computing capacity losses at various ways of data exchange between complex-s computing modules and reconfiguration device. It is shown that the use of an additional reconfiguration control device combined with software test self-control of computing module, and application of control exchange unit, implementing the inter-machine (double) direct memory access reduces the time for computing module performance monitoring and the time of exchange of information between the computing modules, and gives the ability for working computing module to work with failed module memory, which increases the security of information and the stability of the computing system.
