Kadry Hamed, Mohamed A. El-Sayed · International Journal of Computer Applications · 2015
Multicast communication, in which the same message is sending from a source node to a set of destination nodes, is being increasingly demanded in multicomputer systems.It can be used to support several other collective communication operations.2D torus network has many features.So, it has become increasingly important to multicomputer design.This paper presents an efficient multicast wormhole deadlock-free algorithm that Balance Traffic Load on 2D torus network; hence the name BTL algorithm.BTL algorithm handles multicast operation with a fixed number of message-passing steps irrespective of the network size.Also, it is designed such that can send messages to any number of destinations within two communication phases.Results from extensive comparative analysis show that BTL algorithm exhibit superior performance advantages over a well-known algorithm.
