Abstract
A system and method exclusively accesses a shared storage location using a shared algorithm. Competing processors follow the algorithm for reserving exclusive access to the shared storage location. Those competing processors that have not successfully reserved exclusive access honor the reservation of the successful processor and delay their own access attempts. Two critical storage blocks and two delay times are typically used during an attempt to reserve exclusive access for a processor.
