DPillar has recently been proposed as a server-centric data centre network and is combinatorially related to the well-known wrapped butterfly network. ... We use this symmetry property to establish a single-path routing algorithm for DPillar that computes a shortest path and has time complexity O(k log(n)), where k parameterizes the dimension of DPillar ... Acknowledgement This work has been funded by the Engineering and Physical Sciences Research Council (EPSRC) through grants EP/K015680/1 and EP/K015699/1. ...doi:10.1007/978-3-319-26626-8_16 fatcat:5gihumpisjgxbfcsnj4bh32oyy
We use this symmetry property to establish a single-path routing algorithm for DPillar that computes a shortest path and has time complexity O(k), where k parameterizes the dimension of DPillar (we refer ... Moreover, our algorithm is trivial to implement, being essentially a conditional clause of numeric tests, and improves significantly upon a routing algorithm earlier employed for DPillar. ... We are also grateful for the insightful comments of the reviewers which helped to significantly improve this paper. ...doi:10.1109/tpds.2016.2591011 fatcat:ljkrjinwizfjjk6f6t5ztlhhim
. • It is a mature, flexible and efficient tool for simulating large scale systems. • It models network, storage, scheduler and applications. • It has been used extensively for our research in the past ... We will describe the main aspects of the simulator, including system models, traffic models and the large variety of topologies and routings implemented so far. ...
