Abstract

See full text

Adaptive queued locking for control of speculative execution is disclosed. An example apparatus includes a lock to: enforce a first quota to control a number of threads allowed to concurrently speculatively execute after being placed in a queue; and in response to the first quota not having been reached, enable a first thread from the queue to speculatively execute; and an adjuster to change a first value of the first quota based on a result of the speculative execution of the first thread.
