A method for data deduplication during execution of an application on a plurality of computing nodes, including: generating, by a first processor in a first computing node executing the application, a first message to process application data owned by a second computing node executing the application; receiving, by a first network interface (NI) of the first computing node, the first message; extracting, by the first NI, a first key from the first message; determining, by the first NI, the first key is not a duplicate; and placing, by the first NI and in response to the first key not being a duplicate, the first message on a network connecting the first computing node to the second computing node.

Data deduplication at the network interfaces

In a multi-chip module (MCM), integrated circuits are coupled by optical waveguides that convey optical signals. The optical waveguides provide dedicated point-to-point optical links between all pairs of the integrated circuits. Moreover, for a given point-to-point optical link between a given pair of integrated circuits, other integrated circuits in the integrated circuits steal access on the given point-to-point optical link when communicating information to one of the given pair of integrated circuits so that the given point-to-point optical link is shared by more than the given pair of integrated circuits. Furthermore, the integrated circuits recover errors in messages in the optical signals corrupted by collisions on the given point-to-point optical link using erasure coding. In this way, the MCM may provide an optical network with increased bandwidth relative to a point-to-point optical network.
