Abstract: Various embodiments are generally directed to techniques for controlling the use of locks that regulate access to shared resources by concurrently executed portions of code. An apparatus to control locking of a resource includes a processor component, a history analyzer for execution by the processor component to analyze at least one result of a replacement of a lock instruction of a first instance of code with a lock marker to allow the processor component to speculatively execute a second instance of code, and a locking component for execution by the processor component to replace the lock instruction with the lock marker based on analysis of the at least one result, the first and second instances of code to access a resource and the lock instruction to request a lock of access to the resource to the first instance of code. Other embodiments are described and claimed.
