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 11):
A method for performing exclusive control among tasks, the method comprising:\n implementing a lock status storage unit for storing update information that is updated in response to acquisition and release of an exclusive lock by one task and for storing task identification information for identifying a task that has acquired an exclusive lock;\n processing in a critical section included in a first task to be performed by acquiring the exclusive lock, wherein an exclusive execution unit releases the exclusive lock and updates the update information after the processing in the critical section included in the first task; and \n processing in a critical section included in a second task using a nonexclusive execution unit;\n wherein, in a case where the processing in the critical section by the second task has not been successfully completed when a predetermined condition has been reached and the update information has been changed, the nonexclusive execution unit acquires the exclusive lock and causes the processing in the critical section included in the second task to be performed.
