Abstract
In a fault tolerant computing system, a number of processing nodes are connected via a communication channel to a management node. The management node has the function of setting the processing nodes in uniquely different configurations and operating the processing nodes in parallel to execute common application programs in parallel, so that the application programs are run under diversified environments. The management node has the function of respectively distributing request messages to the processing nodes. The configurations of the processing nodes are sufficiently different from each other to produce a difference in processing result between response messages when a failure occurs in one of the processing nodes. Alternatively, the management node has the function of selecting, from many processing nodes, those processing nodes which are respectively set in uniquely different configurations and operating the selected processing nodes in parallel to execute the common application programs.
