Title (EN) LOOSELY-COUPLED LOCK-STEP CHAINING
(FR) CHAÎNAGE À ÉCHELONS FIXES À COUPLAGE LÂCHE
Abstract:
(EN) A system and method enables loosely-coupled lock-step computing including sensors that detect or measure a physical property and server groups. Each server group is serially linked to another server group and includes server instances operating in virtual synchrony. Virtual synchrony middleware receives outputs from multiple server instances and renders a single reply based on the outputs from the multiple server instances. The virtual synchrony middleware replicates and orders incoming requests to the server groups to ensure each of the server instances of that server group receives the same incoming requests in the same order.
(FR) La présente invention concerne un système et un procédé permettant un calcul à échelons fixes à couplage lâche comprenant des capteurs qui détectent ou mesurent une propriété physique et des groupes de serveurs. Chaque groupe de serveurs est connecté en série à un autre groupe de serveurs et comprend des instances de serveur fonctionnant en synchronie virtuelle. Un intergiciel de synchronisation virtuelle reçoit des sorties provenant de multiples instances de serveur et donne une réponse unique sur la base des sorties provenant des multiples instances de serveur. L'intergiciel de synchronisation virtuelle reproduit et ordonne les requêtes entrantes aux groupes de serveurs pour assurer que chacune des instances de serveur de ce groupe de serveurs reçoit les mêmes requêtes entrantes dans le même ordre.
