Abstract
Crossbar switches having 2.sup.n +1 ports and computing clusters are arranged so that each crossbar switch is connected to 2.sup.n processors. Auxiliary processors that perform parallel processing administrative functions and input/output functions are arranged at the remainder ports of the crossbar switches. Exchangers are provided to connect each processor and its crossbar switches. Parallel processing may be executed by the 2.sup.n processors independently of processing by the auxiliary processors for speed. One mounting unit is formed of a crossbar switch of one dimension, the processor group connected to that crossbar switch, and all of the crossbar switches of a different dimension that are connected to one of the processors of the one processor group. The parallel processor system is mounted by just combining mounting units with no need for special LSIs or frames or the like on which to mount the crossbar switches and without the interfaces that connect the processor and the network becoming concentrated in one place.
