Abstract: Methods and apparatus to support the execution of a managed application that is linked to a native library or application are disclosed. The disclosed methods and apparatus support a virtual machine that is associated with the same ISA as the executing platform, while the ISA of the native library or application is of a different ISA. The disclosed methods and apparatus also support the execution of a managed application that is linked with several native libraries or applications that are associated with several different ISAs respectively.

Abstract: 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.

Abstract: Systems, apparatuses, and methods for a hardware and software system to automatically decompose a program into multiple parallel threads are described. For example, a method according to one embodiment comprises: analyzing a single-threaded region of executing program code, the analysis including identifying dependencies within the single-threaded region; determining portions of the single-threaded region of executing program code which may be executed in parallel based on the analysis; assigning the portions to two or more parallel execution tracks; and executing the portions in parallel across the assigned execution tracks.
