In a parallel computer system in which many microprocessor elements are disposed at least in a two dimensional array to communicate data therebetween at a high speed, n bidirectional buses XBi and m bidirectional YBi are respectively arranged in X and Y directions to dispose m by n data processor elements CPUij at intersections of the buses XBi and YBj, thereby connecting these elements respectively to the associated buses XBi and YBj. Each processor element has a unit for selectively establishing a connection between the bus XBi and the bus YBj which are coupled thereto. In a data transfer between two elements sharing neither one of the bidirectional buses in the X and Y directions, there is selected an element which is connected to one of the X-directional-buses linked to one of the elements and which is connected to, one of the Y-directional buses linked to the other one thereof to use the selected element as a relay for establishing a conductive route between the buses.
