Patent ID: 6983390

Claim:
A method for saving a local clock of a data processing area configured on a multicellular platform of data processing resources within the framework of an operating activity, each data processing area being managed by a specific operating system and being configurable and able to be configured by a user from a management tool (PAM) with a view to the execution of said operating activity on at least one current data processing area or on different successive data processing areas, said method comprising the steps of: a) establishing an absolute reference clock for the management tool and by all the configurable data processing areas on said multicellular platform; and, for each current data processing area configured at the request of a user and to which there is associated a current local clock making it possible to manage an operating activity from said operating system, b) calculating and storing, for each operating activity being executed on the current data processing area of said multicellular platform, a backup attribute containing, in addition to the parameters for management of the time of said operating activity, with reference to said current local clock, a time shift parameters of said parameters for management of the time with respect to said absolute reference clock; and, during a subsequent reloading of said operating activity to continue execution on a successive data processing area different from the current data processing area and with which there is associated a successive local clock different from the current local clock associated with the current data processing area, c) recalculating the parameters for management of the time of said operating activity starting from said time shift parameter of the parameters for management of the time with respect to said absolute reference clock; and d) updating said successive different local clock associated with said successive different data processing area, prior to the launching of said operating activity to continue execution.
