Abstract
A group and virtual locking mechanism (GVLM) addresses two classes of synchronization present in a system having resources that are shared by a plurality of threads of execution: (1) synchronization of the multi-access shared resources; and (2) simultaneous requests for the shared resources. Broadly stated, the novel GVLM comprises a lock controller function associated with each thread of execution, and lock instructions executed by the threads that manipulate the lock controller to create a tightly integrated arrangement for issuing lock requests to the shared resources. The plurality of threads of execution may each execute in a different processor. Alternatively, the plurality of threads of execution may each execute in a single processor.
