Abstract
In a method of transferring packets in a network for a parallel processor system handling a one-to-one transfer packet to be transferred from a processor to another processor and a broadcast packet to be transferred from a processor to a plurality of other processors, a transfer request of a broadcast packet is preferentially selected and a check is made to detect whether or not a plurality of processors specified as receivers are in a state in which the packet can be received. The broadcast packet is transferred to the processors found to be in the state in which the packet can be received. The packet transfer is delayed for the other processors in a state in which the packet cannot be received. Namely, only when the state of the processors is changed to the state in which the packet can be received, the broadcast packet is transferred thereto.
