Extended DragonDeBrujin Topology Synthesis Method

By Artem Volokyta Heorhii Loutskii Pavlo Rehida Artem Kaplunov Bohdan Ivanishchev Oleksandr Honcharenko Dmytro Korenko

Scaling high performance computer systems needs increasing the fault tolerance at the design stage of a topology. There are several approaches of designing simple fast routing with fault tolerance. One of effective approach is to ensure fault tolerance at the topology level. This article discusses two methods for optimizing topologies synthesized using Dragonfly and Excess De Brujin. Methods of topology saturation are discusses, which allow to increase the dimension of the system without deterioration of topological characteristics due to the optimization of the synthesis method. Three scaling constraint methods are also proposed to reduce the topology dimension to the desired performance.
