Abstract
A system for data processing with management of a cache consistency in a network of processors including cache memories, the network including plural nodes for access to a main memory interconnected with one another, a set of directories being distributed between nodes of the network, each directory including a table of correspondence between cache lines and information fields on the cache lines. The system includes a first sub-network for interconnection of the nodes with one another, implementing a first message transmission protocol providing read/write access to the directories during any passage in the corresponding nodes of a message passing through the first sub-network, and a second sub-network for interconnection of the nodes with one another, implementing a second message transmission protocol, the second protocol excluding any read/write access to the directories during any passage in the corresponding nodes of a message passing through the second sub-network.
