A data-processing system with cc-NUMA architecture including a plurality of nodes each constituted by at least one processor intercommunicating with a DRAM-technology local memory using a local bus, the nodes intercommunicating using remote interface bridges and at least one intercommunication ring. The at least one processor has access to a system memory space defined by memory addresses. Each node includes a unit for configuring the local memory, for uniquely mapping a first portion of the system memory space, which is different for each node, onto a portion of the local memory and for mapping the portion of the system memory space which as a whole is uniquely mapped onto a portion of the local memory of all the other nodes onto the remaining portion of the local memory, and a SRAM-technology memory for storing labels with associated with a block of data stored in the remaining portion of local memory and each comprising an index identifying the block and bits indicating a coherence state of the block so that the remaining portion of local memory in each node constitutes a remote cache of the node.
