Title (EN) COMPUTER SYSTEM AND METHOD FOR OPERATING MULTIPLE OPERATING SYSTEMS IN DIFFERENT PARTITIONS OF THE COMPUTER SYSTEM AND FOR ALLOWING THE DIFFERENT PARTITIONS TO COMMUNICATE WITH ONE ANOTHER THROUGH SHARED MEMORY
(FR) SYSTEME ET PROCEDE INFORMATIQUES DE COMMANDE DE SYSTEMES D'EXPLOITATION MULTIPLES DANS DIFFERENTES PARTITIONS DU SYSTEME INFORMATIQUE ET PERMETTANT AUX DIFFERENTES PARTITIONS DE COMMUNIQUER ENTRE ELLES PAR UNE MEMOIRE PARTAGEE
Abstract:
(EN) A computer system comprises a plurality of processing modules that can be configured into different partitions within the computer system, and a main memory. Each partition operates under the control of a separate operating system. At least one shared memory window is defined within the main memory to which multiple partitions have shared access, and each partition may also be assigned and exclusive memory window. Program code executing on different partitions enables those partitions to communicate with each other through the shared memory window. Means are also provided for mapping the physical address space of the processors in each partition to the respective exclusive memory windows assigned to each partition, so that the exclusive memory windows assigned to each partition appear to the respective operating systems executing on those partitions as if they all start at the same base address.
(FR) L'invention concerne un système informatique qui comprend une pluralité de modules de traitement que l'on peut configurer en différentes partitions dans le système informatique, et une mémoire principale. Chaque partition fonctionne sous la commande d'un système d'exploitation séparé. Au moins une fenêtre de mémoire partagée est définie dans la mémoire principale à laquelle plusieurs partitions ont un accès partagé, et chaque partition peut aussi se faire attribuer une fenêtre de mémoire exclusive. L'exécution d'un code programme dans différentes partitions permet à ces partitions de communiquer entre elles par la fenêtre de mémoire partagée. Cette invention concerne aussi des moyens permettant de projeter l'espace d'adresses physiques des processeurs dans chaque partition dans les fenêtres de mémoire exclusives respectives attribuées à chaque partition, de façon que les fenêtres de mémoire exclusives attribuées à chaque partition semblent toutes partir de la même adresse de base pour les systèmes d'exploitation respectifs qui s'exécutent dans ces partitions.
