Low Latency Message-Passing for Reflective Memory Networks.

In this paper we present an efficient design for message passing over a reflective memory network. First, we consider the attributes of reflective memory communication networks and the requirements to efficiently build message-passing functionality on these networks. We then introduce the Bill-Board Protocol, a lock-free protocol which provides low-latency send, receive, and multicast functionality to higher-level applications over reflective memory networks. The communication protocol and an implementation on SCRAMNet is described in detail. Lastly, the performance of this protocol is demonstrated. [ABSTRACT FROM AUTHOR]
