ABSTRACT:
An information processing apparatus having a fat tree structure, in which signal transmission across node columns managed by respective processor units is performed through end point bridges included in bridge chips. In this transmission method, the bridge chips perform routing by using node IDs that are given to the respective node columns and levels that indicate the hierarchical depths of the bridge chips, thereby selecting the shortest routes of signals.
