Abstract
In order to determine a transfer path of a message to a receiving-end processor group, a processor includes a routing bit generation circuit, and an exchange switch includes partial broadcast path control circuits and a path control information alteration circuit. In order to define the range of a receiving-end processor group, a network includes transfer control circuits. A crossbar switch includes transfer control circuits associated with output ports and a boundary register group. When a partial broadcast message is transferred from an input port in the downstream direction of an output port, it is decided whether a belonging to the partial broadcast range associated with a connected to the particular input port is connected to the particular output port, whereby the particular partial broadcast message is transferred from the same output port.
