Description
Summary:This paper studies the implementation of efficient multicast protocols for Myrinet, a switched, wormhole-routed Gigabit-per-second network technology. Since Myrinet does not support multicasting in hardware, multicast services must be implemented in software. We present a new, efficient, and reliable software multicast protocol that uses the network interface to efficiently forward multicast traffic. The new protocol is constructed on top of reliable, flow-controlled channels between pairs of network interfaces. We describe the design of the protocol and make a detailed comparison with a previous multicast protocol. We show that our protocol is simpler and scales better than the previous protocol. This claim is supported by extensive performance measurements on a 64-node Myrinet cluster.
