Title (EN) REMOTE ACCESS USING SHARED MEMORY
(FR) ACCES A DISTANCE UTILISANT UNE MEMOIRE PARTAGEE
Abstract:
(EN) A method for exchanging messages between computer systems communicatively coupled in a computer system network. A message (e.g., a read or write command) issent from a software element of a first computer system (e.g., a client computer system) to a second computer system (e.g., a server computer system). A shared memory unit is accessible by the software element of the first computer system and a software element of the second computer system. The shared memory unit of the second computer system is directly accessed, bypassing the processor of the second computer system, and the data of interest is read or written from/to the shared memory u nit. In one embodiment, the method pertains to acknowledgments between softwareelements. A plurality of messages is sent from one software element to another software element. A count of each of the plurality of messages is maintained. An acknowledgment message acknowledging receipt of a prescribed number of the messages is written to a shared memory unit when the count reaches the prescribed number.
(FR) La présente invention concerne un procédé d'échange de messages entre des systèmes ordinateurs communiquant dans un réseau de systèmes ordinateurs. Un message (par exemple, une commande lecture ou écriture) est envoyée depuis un élément logiciel d'un premier système ordinateur (par exemple, un système ordinateur client) vers un second système ordinateur (par exemple, un système ordinateur serveur). Une unité de mémoire partagée est accessible à l'élément logiciel du premier système ordinateur et à un élément logiciel du second système ordinateur. L'unité de mémoire partagée du second système ordinateur est directement accédée, contournant le processeur du second système ordinateur, et les données recherchées sont lues ou copiées.
