| Abstract | A method for providing proactive synchronization in a computer system (100) includes a processor (18A, 18B) requesting exclusive access to a given memory resource (314A-314D). 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 (233) associated with the set including the matching address. The count value may be indicative of the number of requestors contending for the matching address.
La présente invention se rapporte à un procédé de synchronisation proactive dans un système informatique (100). Le procédé selon l'invention consiste : à faire appel à un processeur (18a, 18B) demandant un accès exclusif à une ressource mémoire donnée (314A-314D), ladite demande comportant une ou plusieurs adresses associées à la ressource mémoire donnée ; à comparer chacune des adresses contenues dans la demande à chaque adresse contenue dans une pluralité d'ensemble d'adresses, chaque adresse des ensembles d'adresses pouvant correspondre à une ressource mémoire respective à laquelle un demandeur dispose un accès exclusif ; et à renvoyer, en réponse à la concordance entre une adresse quelconque liée à la demande et une adresse quelconque de la pluralité d'ensembles d'adresses, une valeur de comptage (233) associée à l'ensemble contenant l'adresse concordante. La valeur de comptage peut indiquer le nombre de demandants en concurrence pour l'adresse concordante. |
