A method and system for increasing reliability and availability of a multi-processor network. A system includes a network with at least two nodes, with each node comprising a multi-processor unit (mpu) and memory. The mpu includes one or more processors and a wiretap unit. The wiretap unit and the memory included in the node are coupled to the processors in the node. The wiretap unit is configured to monitor memory accesses of the processors and convey data indicative of such accesses to a second node. The second node maintains a replica of memory in the first node, and is configured to undo modifications to the memory if needed. In the event of a hardware or software fault, the nodes are configured to restart the application on another node.
