CA 2382929

Methods, systems and devices are described for a shared memory disk (MEMDISK). A method, includes setting aside a particular range of a shared memory as a MEMDISK; and providing control for each of several operating systems that compose processing nodes coupled to said shared memory such that none of the processing nodes will attempt to utilize pages within said particular region for non-MEMDISK purposes. The methods, systems and devices provide advantages because the speed and scalability of parallel processor systems is enhanced.

L'invention concerne des procédés, systèmes et dispositifs destinés à un disque à mémoire partagée ("MEMDISK"). Un procédé de l'invention consiste à mettre de côté une région particulière d'une mémoire partagée en tant que mémoire partagée et à permettre la commande de chacun des différents systèmes de fonctionnement composant des noeuds de traitement couplés à ladite mémoire partagée, de manière qu'aucun des noeuds de traitement ne puisse tenter d'utiliser des pages situées dans la région particulière à des fins qui ne soient pas de mémoire partagée. Ces procédés, systèmes et dispositifs sont avantageux en ce qu'ils augmentent la vitesse et la capacité dimensionnelle de systèmes à processeurs parallèles.
