Abstract

A method for lock acquisition includes adding a current contention state of a lock to a contention history. The lock includes a memory location for storing information used for excluding accessing a resource by one or more threads while another thread accesses the resource. The method includes combining the contention history with a lock address for the lock to form a predictor table index, and using the predictor table index to determine a lock prediction for the lock. The prediction includes a determination of an amount of contention.
