Simulated Annealing for Edge Partitioning
Résumé
In distributed graph computation, graph partitioning is an important preliminary
step, because the computation time can significantly depend on how the graph has been split among
the different executors. In this paper, we propose a framework for distributed edge partitioning
based on simulated annealing. The framework can be used to optimize a large family of partitioning
metrics. We provide sufficient conditions for convergence to the optimum as well as discuss which
metrics can be efficiently optimized in a distributed way. We implemented our partitioners in
Apache GraphX and performed a preliminary comparison with JA-BE-JA-VC , a state-of-the-art
partitioner that inspired our approach. We show that our approach can provide improvements,
but further research is required to identify suitable metrics to optimize as well as to design a more
efficient exploration phase for our algorithm without sacrificing convergence properties.
