Abstract: To improve the performance of data parallel pipelines on computational grids, the algorithm of simulated annealing is used to optimize scheduling. An experimental method is used to determine the initial control parameter, and a random method is used to choose the next scheduling scheme. By adjusting the stability times of the best scheduling scheme, the trade-offs between optimization cost and optimization effect can be made. Experiments show the simulated annealing here can effectively optimize the scheduling of pipelines.
