ABSTRACT:
A method for providing proactive synchronization in a computer system includes a processor requesting exclusive access to a given memory resource. The request may include one or more addresses associated with the given memory resource. The method also includes comparing each of the addresses in the request to each address in a plurality of sets of addresses. Each address in the sets of addresses may correspond to a respective memory resource to which a requestor has exclusive access. In addition, in response to any address of the one or more addresses matching any address in the plurality of sets of addresses, the method includes returning a count value associated with the set including the matching address. The count value may be indicative of the number of requestors contending for the matching address. Software may utilize this count value to proactively choose an item with lower contention probabilities in subsequent attempts.
