Abstract
A system and associated method for mutually exclusively executing a critical section by a process in a computer system. The critical section accessing a shared resource is controlled by a lock. The method measures a detection time when a lock contention is detected, a wait time representing a duration of wait for the lock at each failed attempt to acquire the lock, and a delay representing a total lapse of time from the detection time till the lock is acquired. The delay is logged and used to calculate an average delay, which is compared with a suspension overhead time of the computer system to determine whether to spin or to suspend the process while waiting for the lock to be released. The number of processes waiting for the lock and the number of processes suspended are respectively counted to optimize the method.
