Abstract
A system and method for guaranteeing transactional fairness among multiple requesters contending for a common resource in a cache-coherent multiprocessor system is described. Batch processing is used to control servicing of multiple requests made by multiple requesters (such as processors) of a common resource in a cache-coherent multiprocessor system. Specifically, identification numbers are assigned to requests as they are received from the multiple requesters. The identification numbers are then used in conjunction with batch processing to prioritize and guarantee servicing of the requests.
