Methods and system for providing synchronization of a multi-threaded application includes analyzing a source file of the application to identify one or more synchronization annotations contained therein, wherein the synchronization annotations are defined using declarative statements. One or more synchronization annotation processors are identified and invoked for processing the one or more synchronization annotations identified in the source file so as to generate code files. The source file is compiled to generate one or more class files by compiling the procedural code within the source file to generate one or more class files, and compiling the code files to generate the one or more class files. The class files associated with the code files are used by the multiple threads during execution of the application to arbitrate access to methods and data manipulated by classes within the class files associated with the procedural code.

In one embodiment, a processor comprises an execution core, a level 1 (L1) data cache coupled to the execution core and configured to store data, and a transient/transactional cache (TTC) coupled to the execution core. The execution core is configured to generate memory read and write operations responsive to instruction execution, and to generate transactional read and write operations responsive to executing transactional instructions. The L1 data cache is configured to cache memory data accessed responsive to memory read and write operations to identify potentially transient data and to prevent the identified transient data from being stored in the L1 data cache. The TTC is also configured to cache transaction data accessed responsive to transactional read and write operations to track transactions. Each entry in the TTC is usable for transaction data and for transient data.

Transient transactional cache

A method and system for providing an efficient and convenient mechanism for class loading is presented. A present system and method virtual machine includes a bulk class loading component, normal class loader and execution engine. The bulk class loading component performs bulk loading of classes in a single pass of respective code sources. The normal class loader performs normal class loading activities, including normal class hierarchy tree searches and single class loading with multiple search traversals. In one embodiment, a bulk class identification component identifies classes for bulk loading. Classes can be identified for bulk class loading based upon designated characteristics or attributes. For example, a designated characteristic can include a class that is loaded between two points in time (e.g., from startup to a predetermined time after startup). The designated characteristic can be a relationship to other classes, including dependency relationships to classes identified for bulk loading based upon other criteria.
