Efficient Broadcast on Computational Grids
نویسندگان
چکیده
Collective communication operations such as broadcast, gather and reduce are potential performance bottlenecks for scientific computing software. With the advent of wide-area distributed computing and computational Grids, achieving efficient collective communication for applications running on geographically distributed computers becomes of paramount importance. We propose an efficient broadcast algorithm, that is applicable to any connected network and show that it improves the performance of the MPI broadcast operation.

متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...
