| 1. A signal transmission method for transmitting a signal to be transmitted between different processor units in an information
processing apparatus having a fat tree structure including a plurality of processor units, the method comprising:
issuing a signal from one of the processor units; and
relaying the signal by a plurality of bridge units, wherein
the relaying of the signal includes:
inputting the signal to a bridge unit; and
selecting which bus to output to and outputting the signal thereto based on a number of a column to which the bridge unit
belongs, the number being given to each column consisting of a processor unit and bridge units managed by the processor unit
in a matrix of the fat tree structure, a level number of a row to which the bridge unit belongs, the level number being given
to each row consisting of bridge units in the matrix, and a number of a column of bridge units managed by a destination processor
unit.
