Abstract

The embodiment of the invention discloses a scheduling method and related devices of multi-core processors. The scheduling method and related devices of the multi-core processors are used for refining tasks which are distributed to the processors before scheduling is conducted. The scheduling method includes the steps that snapshots are generated for topological structures between the processors and a high-speed cache in a system, a scheduling policy is generated according to the snapshots and control information which is input by a user, processor resources are distributed for the tasks to be scheduled according to the snapshots, the scheduling policy and attributes of the tasks to be scheduled, and the tasks to be scheduled are executed by using the processor resources which are distributed to the tasks to be scheduled.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multi-core processor scheduling method and a related device. Background technique [0002] Multi-core processors are the main trend of processor development in the future. The number of cores integrated in a single physical processor has developed from the initial dual-core to quad-core, eight-core, or even more. With the continuous improvement of integration, the scheduling As far as the processor is concerned, common multi-core, homogeneous multi-core and multi-core heterogeneous platforms with different processing capabilities put forward higher requirements for the scheduler, and the scheduling scenarios faced by the scheduler tend to be more complicated. [0003] When the Linux system starts, the BIOS (Basic Input Output System, basic input and output system) will provide static information related to the processor. The Linux system is based on the static information rel...
