Optimal Placement of Processors based on Effective Communication Load
نویسندگان
چکیده
This paper presents a new technique for the optimum placement of processors to minimize the total effective communication load under multi-processor communication dominated environment. This is achieved by placing heavily loaded processors near each other and lightly loaded ones far away from one another in the physical grid locations. The results are mathematically proved for the Algorithms are described. Keywords—Ascending Sort Index Vector, Effective Communication Load, Effective Distance Matrix, Optimal Placement, Sorting Order.

Lower Bounds on Communication Loads and Optimal Placements in Torus Networks
ÐFully populated torus-connected networks, where every node has a processor attached, do not scale well since load on edges increases superlinearly with network size under heavy communication, resulting in a degradation in network throughput. In a partially populated network, processors occupy a subset of available nodes and a routing algorithm is specified among the processors placed. Analogou...
