Abstract
Barrier synchronization between multiprocessors is performed at high speed while reducing overhead of parallel processing without adding any special hardware mechanism. A parallel computer synchronization method is provided to synchronize threads through barrier synchronization for parallel execution of plural threads on plural processor modules. The parallel computer has plural processor modules (Pand P) equipped with plural processor cores (cputo cpu). The processor cores are each assigned plural threads (Thto Th) to execute multithread processing. The plural threads (Thto Th) are set in hierarchical groups (Gr), and barrier synchronization is performed on each group separately.
