In this work, we propose to logically embed a ring in a point-to-point network topology. Snoop messages use the logical ring, while other messages can use any link in the network. The resulting design is simple and low cost. Perhaps the main drawback of the embedded ring approach is that snoop requests may suffer long latencies or induce many snoop messages and operations. In this work, we address these issues and, as a result, provide simple and competitive cache coherence protocol designs.Jose was our mentor and manager during our first co-op at IBM. He did it so well that, besides convincing us to apply to PhD programs, we kept going back to IBM during our PhDs almost every summer. His help and support have been crucialanbsp;...
