The ParPar system is a high-performance cluster environment supporting a multiuser parallel workload. Its design follows a master-nodes structure, where the master controls all aspects of system activity using a dedicated control network. As nearly all control messages are multicast to a set of nodes, we implemented a reliable multicast protocol for this(More)
We design and analyze communication algorithms for an optical switch based on the electroholographic effect, that provides capabilities for configuration changes and a limited multicast. As configuration changes incur a high overhead, we suggest the use of a high-speed forwarding unit as part of the network interface. We develop broadcast algorithms that(More)
