A process scheduling method based on multi-core processing

Abstract

The invention discloses a process scheduling method based on multi-core processing, which relates to the technical field of multi-core processing process scheduling. The method includes grouping multi-core processors into a computing processor group CPUc and a storage processor group CPUm;setting a corresponding process scheduling queue for the processors in the processor group respectively; a monitor monitoring and determining whether the current process of the process pool is a ready process or not, allocating a ready process to a corresponding ready queue according to a multi-core processing process allocation method; the processor using the corresponding scheduling algorithm to process the ready process in the process scheduling queue. By grouping the multi-core processors into a computing processor group CPUc and a storage processor group CPUm and dividing the ready process into a computing ready process and a storage ready process, the invention improves the process processing efficiency and reduces the waste of processor resources.

Description

technical field [0001] The invention belongs to the technical field of multi-core processing process scheduling, and in particular relates to a process scheduling method based on multi-core processing. Background technique [0002] The process scheduling of multi-core processors is generally divided into global queue scheduling strategy and local queue scheduling strategy. Among them, each process execution phase in the global queue scheduling strategy can use all processor resources, and this scheduling strategy leads to complex scheduling management and waste of processor resources. The local queue scheduling strategy first assigns all processes to the corresponding process queue of the processor, and then each queue performs self-scheduling in the queue. Although this scheduling strategy improves the utilization rate of the processor to a certain extent. However, different types of ready processes are in the process queue corresponding to the same processor, the efficien...
