Toward High-Performance Delta-Based Iterative Processing with a Group-Based Approach
文献摘要：
Many systems have been built to employ the delta-based iterative execution model to support iterative algo-rithms on distributed platforms by exploiting the sparse computational dependencies between data items of these iterative algorithms in a synchronous or asynchronous approach.However,for large-scale iterative algorithms,existing synchronous solutions suffer from slow convergence speed and load imbalance,because of the strict barrier between iterations;while existing asynchronous approaches induce excessive redundant communication and computation cost as a result of being barrier-free.In view of the performance trade-off between these two approaches,this paper designs an efficient execution manager,called Aiter-R,which can be integrated into existing delta-based iterative processing systems to efficiently support the execution of delta-based iterative algorithms,by using our proposed group-based iterative execution approach.It can efficiently and correctly explore the middle ground of the two extremes.A heuristic scheduling algorithm is further proposed to allow an iterative algorithm to adaptively choose its trade-off point so as to achieve the maximum efficiency.Experimen-tal results show that Aiter-R strikes a good balance between the synchronous and asynchronous policies and outperforms state-of-the-art solutions.It reduces the execution time by up to 54.1％and 84.6％in comparison with existing asynchronous and the synchronous models,respectively.
