Design And Implement Of Task Scheduling In Real-time Data Platform For Power Grid

The task scheduling algorithm this paper proposed is a solution which aimed to solve the problems of imbalanced load and poor timeliness with the tradition task scheduling in the real-time data platform. Based on investigating a great deal of domestic and international documents, the basic theory and main method of real-time scheduling technology and load balancing technology is researched deeply. In view of the characteristic of task in real-time data platform for power gird, a task scheduling algorithm based on the priority and dynamic feedback is proposed. This algorithm both has considered the rate of loading on server nodes, and has given attention to an important index——Deadline Miss Ratio. The algorithm guaranteed the loading balance and timeliness of task fully, and improved the performance of real-time data platform greatly. Finally, this article designed and implemented a task scheduling service for the real-time data platform, and analyzes the performance through the experiment.
