Most of the high-end computing clusters found today feature multi-way SMP nodes interconnected by an ultra-low latency and high bandwidth network. InfiniBand is emerging as a high-speed network for such systems. InfiniBand provides a scalable and efficient hardware multicast primitive to efficiently implement many MPI collective operations. However, employing hardware multicast as the communication method may not perform well in all cases. This is true especially when more than one process is running per node.
