  Abstract:
The ability to perform multicast communication efficiently in parallel computing systems is increasingly becoming an essential feature of these systems. Therefore, any emerging parallel architecture must be able to provide effective multicasting performance. OTIS-based multi-computer systems are parallel systems that efficiently exploit optical connections between distant nodes, while using electronic connections for physically close processors. No previous work has attempted to determine an optimal multicast communication scheme for OTIS networks. This paper presents two approaches to implement efficient multicast communication in wormhole-routed OTIS networks, for the two different possible unicast routing schemes of these networks, in the absence of hardware multicast support. A simulation-based evaluation of the different multicast techniques is presented. The performance of the two proposed multicasting schemes are also compared under different working conditions.
