INFORMATION PROCESSING SYSTEM AND CONTROL METHOD OF INFORMATION PROCESSING SYSTEM

摘要

A node includes a sending unit that sends a signal to another node; a receiving unit that receives a signal from another node; a determining unit that determines, when the sending unit sends a signal to the other node, that synchronization has been established with the other node, that determines, when the receiving unit receives a signal from another node, that synchronization has been established with the other node, and that determines, when a node in which synchronization has already been established with the other two nodes in each of which synchronization has been established, that synchronization has been established with the nodes; and a selecting unit that selects an information processing apparatus that is not determined, by the determining unit, that synchronization has been established as the other node at the sending destination for the signal.

主权项

1. An information processing system comprising:
a plurality of information processing apparatuses, wherein each of the information processing apparatuses includes
a sending unit that sends a signal to another information processing apparatus,a receiving unit that receives a signal from another information processing apparatus,a determining unit that determines, when the sending unit sends a signal to another information processing apparatus, that synchronization has been established with the information processing apparatus at the sending destination, that determines, when the receiving unit receives a signal from another information processing apparatus, that synchronization has been established with the information processing apparatus at the sending source, and that determines, when an information processing apparatus in which synchronization has been established with the information processing apparatus that has been determined that synchronization was established is further present, that synchronization has been established with the information processing apparatus that has been determined to be further present, anda selecting unit that selects an information processing apparatus that is not determined, by the determining unit, that synchronization has been established as an information processing apparatus at the sending destination of a signal.
