Abstract

The invention discloses a finite-time parallel task scheduling method and device. The method comprises the following steps: generating a task distribution mode which enables a task to be split into aplurality of subtasks with the same number as a slave processor, and generating a slave processor scheduling mode corresponding to the task distribution mode based on the task distribution mode; usinga genetic algorithm to iteratively execute crossover and mutation processing for multiple times for the combination of the task allocation mode and the slave processor scheduling mode to generate a new combination of the task allocation mode and the slave processor scheduling mode; and respectively calculating task completion time of the combination of the plurality of task allocation modes and the slave processor scheduling mode, and scheduling the task by using the combination of the task allocation mode with the minimum task completion time and the slave processor scheduling mode. According to the method, parallel task scheduling based on the time window model can be executed, the scheduling execution speed and efficiency are optimized, and the product quality is further improved.

Description

technical field [0001] The present invention relates to the field of task scheduling, and more specifically, to a limited-time parallel task scheduling method and device. Background technique [0002] A complete web software project has a layer of rigorous functional logic and task scheduling coding implementation under the UI layer. Then, in the case of concurrent multi-tasks, how to execute each task in an orderly and efficient manner is a very prominent problem. , The length of time for the task even directly affects the market competitiveness of the product. In general, scheduling problems assume a set of resources and a set of consumers served by those resources according to a specific policy. The nature of consumers and resources, and constraints on them, influences the search for effective strategies for managing the way consumers access and use resources in order to optimize some desired performance metric. [0003] For a heterogeneous multiprocessor system, the in...
