Abstract
Official abstract text for this publication.
Example methods and apparatus to manage object locks are disclosed. A disclosed example method includes intercepting a processor request to apply the lock on the object, identifying a performance history of the object based on a number of instances of contention, reducing computing resources of the processor by, when the number of instances is below a threshold value, generating a lock bypass for the object to cause speculative execution of target code within the object, and preventing speculative execution by applying the lock on the object when the number of instances is above the threshold value.
First claim
Opening claim text (preview).
What is claimed is: 1. A method to control a lock of an object, comprising: intercepting, by executing an instruction with a processor, a request to apply the lock on the object; identifying, by executing an instruction with the processor, a performance history of the object based on a number of instances of contention; reducing computing resources of the processor by, when the number of instances satisfies a threshold: generating, by executing an instruction with the process…
