Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] Such as figure 2 Shown is a structural diagram of the multi-core processing system of the present invention, which includes multiple processor cores and / or multiple processors, and also includes a partition module and a startup module.

[0062] Partition module: The user specifies the resource configuration of each partition according to the computer's processor and / or processor core and memory configuration. Each partition includes at least one processor and / or one processor core, and the resources of each partition are passed through The Grub parameter is passed to the operating system (for example, the parameter "cpumask=13, mem1=1024M, mem2=512M" indicates that the entire system has two partitions: the first partition has a single-core processor or processor core, and 1024M memory; The second partition has three single-co...

Abstract

The invention discloses a multi-core processing system and a management method thereof for solving the scalability problem of the symmetrical multi-processing system. The system includes a plurality of processor cores and / or a plurality of processors, a partition module and a startup module: the partition module is used to analyze and save resource configuration parameters and startup parameters of each partition specified by the user; the partition It includes at least one processor and / or one processor core; the startup module is used to start a privileged operating system and a non-privileged operating system managed by the privileged operating system. The management method includes the following steps: step S100, the partition module parses and saves the resource configuration parameters of each partition specified by the user; step S200, starts the privileged operating system and the privileged operating system managed Unprivileged operating system. The invention effectively utilizes the processor resources and solves the scalability problem of the symmetric multiprocessing system.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multi-core processing system and a management method for solving the scalability of a symmetric multi-processing system (Symmetric Multi-Processing, SMP). Background technique [0002] With the development of Moore's law and multi-core technology, the scalability problem of symmetric multi-processing system has become more and more prominent, that is, due to the synchronization and mutual exclusion between processors or processor cores, the performance of the entire system cannot The number of processor cores increases linearly, and even when the number of processors or processor cores is too large, the system performance will gradually decline. [0003] The full name of SMP is "Symmetrical Multi-Processing" (Symmetrical Multi-Processing) technology, which means that a group of processors (multi-CPU) are assembled on a computer, and the memory subsystem and bus structure are ...
