Abstract	The dynamic broadcast problem is the communication problem where source packets to be broadcast to all the other nodes are generated at each node of a parallel computer according to a certain random process, such as a Poisson process. The lower bounds on the average reception delay required by any oblivious dynamic broadcast algorithm in a d-dimensional hypercube are /spl Omega/(d+1/1-/spl rho/) when packets are generated according to a Poisson process, where p is the load factor. The best previous algorithms for hypercubes only achieve /spl Omega/(d/1-/spl rho/) average reception delay. In this paper, we propose dynamic broadcast algorithms that require optimal O(d+1/1-/spl rho/) average reception delay in d-dimensional hypercubes and n/sub 1//spl times/n/sub 2//spl times//spl middot//spl middot//spl middot/n/sub d/ tori with n/sub i/=O(1). We apply the proposed broadcast scheme to a variety of other network topologies for efficient dynamic broadcast and present several methods for assigning priority classes to packets.
