Information of an action of fact confirmation performed between nodes that are objects relating to fact confirmation in an application procedure is read from a predetermined storage unit that previously stores whether an action of fact confirmation is an action of operating information or an action of confirming information, and based on the read information of the action, when a fraud is committed in an action of operating information, reliability of the application procedure is calculated based on a probability of a detection of a fraud in an action of confirming information performed in a node connected to the action of operating information.

Computer program product, method, and apparatus for calculating reliability of an application procedure for fraud using an estimated probability of detection of fraud

A computer-readable recording medium storing a program to make a computer execute a process, the process including generating normal/abnormal patterns of paths between a start point node of application procedure and a reliability verification point node based on a node information that stores an object related to a fact confirmation at application procedure as a node and a path information that stores processing executed between nodes as path; determining whether it is possible to reach the verification point node from the start point node only via normal paths regarding each normal/abnormal pattern; generating a calculation expression to find the reliability of the application procedure as the total generation probability of the normal/abnormal patterns which was determined as reachable; and calculating the reliability of the application procedure by applying the probability of normality of the paths stored corresponding to each path in the path information.

An inter-processor synchronization control system in a distributed memory type parallel computer comprises a unit for detecting an establishment of the synchronization of all PEs, a status request register unit provided for each PE for independently issuing a status request through a status request signal, a unit for determining the issues of requests from status request registers of all PEs, a unit for distributing the determination to all PEs and a status detecting register for detecting the status according to the distributed determination and the output of the synchronization establishment detection unit. The inter-processor synchronous control system detects the status of all PEs when the synchronization is established in all PEs.

Synchronization control system in a parallel computer

A communication control system controls communication between parallel computers using a wormhole routing. The system comprises units for connecting a plurality of computer nodes by relay channels within a network to continuously transfer a message divided into a plurality of minimum data units for transmission. Storing units are provided in respective nodes for storing the minimum data units, the number of storing units corresponding to the number of relay channels from the originating node to the most remote node plus 1. Therefore, a deadlock in a communication is avoided, and a high speed communication can be realized.
