    摘要： Example methods and apparatus to manage object locks are disclosed. A disclosed example method includes receiving an object lock request from a processor, the lock request associated with object lock code to lock an object, and generating object lock-bypass code based on a type of the processor, the object lock-bypass code to execute in a managed runtime in response to receiving the object lock request. The example method also includes identifying a type of instruction set architecture (ISA) associated with the processor, invoking a checkpoint instruction for the processor based on the identified ISA, suspending the object lock code from executing and executing target code when the object is uncontended, and allowing the object lock code to execute when the object is contended.

    摘要： In one embodiment, an object oriented programming language can pre-fetch objects and fields within those objects to a cache memory. A hardware performance monitor can be used to identify loads that read from an address that is frequently absent from a memory. Instrumentation can be used to mark the objects that include the frequently missed address. A compiler can identify chains of objects that are frequently absent from memory. The chains of objects can be pre-fetched without regard to the types of object. Other embodiments are described and claimed.
