Abstract
A parallel computer system capable of arbitrarily selecting nodes participating in barrier synchronization while enabling an arbitrary number of node groups to independently execute a process requiring the barrier synchronization. A communication network for the parallel computer system includes a plurality of routing controllers. Each routing controller has a register for setting a predetermined number of receipts of barrier synchronization request messages from other routing controllers, a destination to which the barrier synchronization request message is transmitted, and a destination to which a barrier synchronization establishment message is transmitted. If a destination of transmission of the barrier synchronization request message is set when completing a predetermined number of receipts of the barrier synchronization request messages and receipts of a barrier synchronization request message from a self-node, the barrier synchronization request message is transmitted to that destination of transmission. If the transmission destination is not set, the barrier synchronization establishment message is transmitted to the set transmission destination of the barrier synchronization establishment message. When receiving the barrier synchronization establishment message, the barrier synchronization establishment message is also transmitted to the set transmission destination of the barrier synchronization establishment message.
