Abstract
Spin locks are task synchronization mechanism used to provide mutual exclusion to shared software resources. Spin locks have a good performance in several situations over other synchronization mechanisms, i.e., when on average tasks wait short time to obtain the lock, the probability of getting the lock is high, or when there is no other synchronization mechanism. In this paper we study the effect that the execution of spinlocks create in multithreaded processors. Besides going to multicore arch...
