the present invention relates to the execution of data flow graphs with distributed calculations. More specifically, it relates to a system for execution of a dataflow graph (300), said dataflow graph (300) comprising: at least two first actors (310, 311) each comprising means for independently executing a calculation on a same dataset comprising at least one datum, and producing a quality descriptor of the dataset, the execution of the calculation by each of said at least two first actors being triggered by a synchronization system; a third actor (320), comprising triggering means for the execution of the calculation by each of said at least two first actors, and initializing a timer configured to emit an interruption signal when a duration is expired; a fourth actor (330), comprising means for executing, at the latest at the interruption signal of said timer: the selection, from the set of said at least two first actors having produced a quality descriptor, of which the descriptor presents the most favourable value; and the transfer of the dataset calculated by the selected actor. |
