Abstract:

Systems for managing shared computing resources. In a multi-process computing environment a concurrency object data structure pertaining to a shared resource is made available to be accessed by two or more processing entities. The concurrency object comprises a consecutive read count that tracks the number of consecutive read requests that have been received for shared read access to the shared resource. A shared concurrency access state is entered based on comparison of the consecutive read count to a threshold value. Entering the shared concurrency access state begins a period during which grant of further shared access requests do not require semaphore operations or other atomic operations that pertains to the shared resource.
