Expanded stochastic DAG model

  • Received Date: 20 Apr 2007

  • Considering the fact that parallel program structure can induce the randomcity of tasks- computing and communication cost, the definition of stochastic directed acyclic graph(DAG) was expanded, in which the heterogeneity and the parallel program structure were considered together. Based on this model, the method to computing the nodes- earliest start time(EST) and standard deviation were presented, which was expressed as the expectation operator of a summation of standard deviation and the mean. A parallel program modeling method was provided based on the expanded stochastic DAG. The expanded definition has been validated by experiments. The results show that by optimizing the parallel program structure and considering the heterogeneous environment, the parallel program execution efficiency can be improved greatly, as well as the load-balance.
