ABSTRACT:
A parallel computer system includes a plurality of processor units, a data transfer network for interconnecting the processor units, a synchronizing network for allowing program execution to be performed synchronously by the individual processor units, a connecting unit for connecting the individual processor units and the synchronizing network, and an input unit connected to the synchronizing network. The connecting unit connects selectively the individual processor units to the synchronizing network in accordance with information inputted via the input unit. With the parallel computer system, a program can be executed synchronously in parallel by using a desired number of processor units of those incorporated in the system, whereby availability of processor resources of the system can be enhanced.
