In the system, each of the information processors has identification information containing a parameter for determining a master-slave relationship among the information processors and an algorithm for determining the master-slave relationship. When the information processors communicate with each other, an information processor exchanges its own identification information with the identification information of the other information processor and further makes a response of information processing on the basis of the identification information brought from the other information processor. ## Claims ### Claim 1 A managing method for an information processor system including a plurality of information processors, comprising: allowing each of the information processors to possess identification information containing a parameter for determining a master-slave relationship among the information processors and an algorithm for determining the master-slave relationship; allowing the information processors to exchange the identification information when the information processors communicate with each other; and allowing each of the information processors to make a response of information processing based on the identification information. ### Claim 2 (depends on 1) The managing method of claim 1, wherein the identification information includes a first parameter for determining the master-slave relationship among the information processors, a second parameter representing a classification of the information processor, an information representing the presence/absence of a master information processor, an identification information of the master information processor, an information representing the presence/absence of a slave information processor, and an identification information of the slave information processor. ### Claim 3 (depends on 2) The managing method of claim 2, further comprising: classifying the information processors into ranks designated by the second parameter. ### Claim 4 (depends on 3) The managing method of claim 3, further comprising: when information processors under states undecided about the master-slave relationship are communicated with each other, allowing the information processors to exchange the first parameters; and determining the master-slave relationship between the information processors. ### Claim 5 (depends on 4) The managing method of claim 4, further comprising: bringing an information processor under a slavery state to stop an operation to determine the master-slave relationship among the information processors. ### Claim 6 (depends on 4) The managing method of claim 4, further comprising: allowing an information processor under a slavery condition to only reply readout of information representing that the information processor is under the slavery state and the identification information of a master information processor for the information processor. ### Claim 7 (depends on 4) The managing method of claim 4, further comprising: when a first master information processor in a first group where the master-slave relationship among the information processors has been already established communicates with a slave information processor in a second group, allowing the master information processor to acquire the identification information of a second master information processor in the second group; and determining the master-slave relationship between the first master information processor and the second master information processor based on the identification information. ### Claim 8 (depends on 4) The managing method of claim 4, further comprising: allowing the information processors to break off the master-slave relationship previously determined about the information processors based on a transmission command to clear the master-slave relationship. ### Claim 9 An information processor system comprising: a plurality of information processors connected with each other through a transmission line, each of the information processors having its own identification information containing a parameter for determining a master-slave relationship among the information processors and an algorithm for determining the master-slave relationship, wherein when at least two information processors are communicated, the two information processors exchange their identification information, and one of the two information processors determines the master-slave relationship between the two information processors based on the identification information brought from the other of the information processors and the own algorithm for determining the master-slave relationship.
