Abstract
An exclusive access control method is executed by a computer having an operating system that when an excluded thread accesses a shared resource, executes a first exclusive access control process of prohibiting the excluded thread from attempting to access the shared resource until exclusive access control is released, the exclusive access control process being executed according to a number of attempts, by the excluded thread, to access the shared resources. The exclusive access control method includes counting by at least one second thread, including the excluded thread and different from a first thread, the number of attempts to access the shared resource, when the first thread executes a second exclusive access control process of allowing the excluded thread to attempt to access the shared resource until the excluded thread is permitted access; and storing to a memory area by the second thread, the counted number of attempts.
