Abstract:
A system for parallel processing tasks by allocating the use of exclusive locks to process critical sections of a task. The system includes storing update information that is updated in response to acquisition and release of an exclusive lock. When processing a task which includes a critical section containing code affecting execution of the other task, an exclusive execution unit acquires an exclusive lock prior to processing the critical section. When the section has been processed successfully, the lock is released and update information updated. Meanwhile a second task, whose critical section does not contain code affecting execution of the other task may run in parallel, without acquiring an exclusive lock, via a nonexclusive execution unit. The nonexclusive execution unit determines that the second critical section has successfully completed if the update information has not changed during processing of the second critical section.

Claim (Index 14):
The method according to  claim 13 , wherein:\n when one task has acquired the exclusive lock, the lock status storage unit includes a storage area for storing the task identification information; and when all tasks have released the exclusive lock, the lock status storage unit includes a storage area for storing the update information; when acquiring the exclusive lock, the exclusive execution unit reads the update information from the lock status storage unit, writes the lock information indicating that the exclusive lock has been acquired to the lock status storage unit, and writes the task identification information for identifying the first task to the lock status storage unit; and when releasing the exclusive lock, the exclusive execution unit writes the lock information indicating that the exclusive lock has been released to the lock status storage unit and writes new update information obtained by updating the update information read in acquisition of the exclusive lock to the lock status storage unit.
