Abstract
A method and device for digital data processing based on a data flow processing model is suitable for the execution, in a distributed manner on multiple calculation nodes, of multiple data processing operations modelled by directed graphs, where two different processing operations include at least one common calculation node. The device includes an identification processor configured to, from a valued directed multi-graph made up of the union of several distinct processing graphs and divided into several valued directed sub-multi-graphs, called chunks, and whose input and output nodes are buffer memory nodes of the multi-graph, identify a coordination module for each chunk. Furthermore each identified coordination module is configured to synchronize portions of processing operations that are to be executed in the chunk with which the respective coordination module is associated, independently of portions of processing operations that are to be executed in other chunks.
