Abstract
There is provided a distributed system having a plurality of nodes connected by a network. Each of the nodes includes: a common-parameter-value determining unit for determining a common-parameter-value from values of a parameter (each value being possessed by a corresponding one of the nodes); a common-operation execution unit for executing a common-operation using, as its input, a value of the parameter or the common-parameter-value; a send/receive unit for exchanging, via the network, the parameter values used for the determination of the common-parameter-value and the results of the common-operation execution with the other nodes; and a fault identification unit that compares the common-operation execution results collected from all the nodes and determines that an error occurs if not all the results are the same.
