    • A data processing apparatus having a function of carrying out data process so that data flows between any nodes within a data network composed of a plurality of nodes via a communication channel for transmitting data unidirectionally includes a communication route matrix forming unit for forming a matrix constituted by a plurality of elements, each of which corresponds to the number of direct communication routes, directly linking each pair of nodes and including the above communication channels, so as to associate data-transmitting nodes with data-receiving nodes; a unit for calculating the number of patterns of communication routes that performs a given computation on the basis of the matrix formed by the communication route matrix forming unit, and thus calculates the number of patterns of all communication routes existing between a certain node and any one of the other nodes; and a unit for detecting a route between specified nodes that detects a specified pair of nodes, in which the number of patterns of communication routes calculated by the unit for calculating the number of patterns of communication routes is equal to or larger than a predetermined value, as patterns of communication routes causing a deadlock.
    • 一种具有执行数据处理功能的数据处理装置,使得数据在由多个节点组成的数据网络内的任何节点之间经由用于单向发送数据的通信信道流动,具有通信路由矩阵形成单元,用于形成由 多个元素,每个元素对应于直接通信路由的数量,直接链接每对节点并包括上述通信信道,以便将数据发送节点与数据接收节点相关联; 用于计算基于由通信路由矩阵形成单元形成的矩阵执行给定计算的通信路由的模式数量的单元,并且因此计算存在于某个节点与任何一个之间的所有通信路由的模式数 的其他节点; 以及用于检测检测特定节点对的特定节点之间的路由的单元,其中,由用于计算通信路由的模式数量的单元计算出的通信路由的模式数量等于或大于预定值, 作为造成僵局的通信路由的模式。
