Exploring pattern-aware routing in generalized fat tree networks
Germán Rodríguez, Ramón Beivide, Cyriel Minkenberg, Jesús Labarta, Mateo Valero · 2009
New static source routing algorithms for High Performance Computing (HPC) are presented in this work. The target parallel architectures are based on the commonly used fat-tree networks and their slimmed versions. The evaluation of such proposals and their comparison against currently used routing mechanisms have been driven by realistic traffic generated by HPC applications. Our experimental framework is based on the integration of two existing simulators, one replaying an MPI application and another simulating the network details. The resulting simulation platform has been fed with traces from real executions.
