Performing thread distribution method for multi-nucleus multi-central processing unit

Abstract

This invention discloses a kind of execute Thread allocation method of multiple kernels central processors. At first establish the execute choice and the list corresponding with the original code and during start up the every execute choice's execute Thread generate the execute choice and the list corresponding with the execute Thread identification code and then according to the two kinds of list allocate for the execute Thread. Besides, it also can increase one priority specify list in the corresponding relationship list between the execute choice and the original code if it in order to identify the every execute choice's execute Thread grouping priority specify types or offer a potential resource collision interface further priority consider the priority specify or the potential resource collision setting when executing the Thread grouping.

Description

technical field [0001] The present invention relates to an execution thread scheduling processing method of a processor, in particular to an execution thread allocation method proposed under the framework of a multi-core multi-central processing unit (Central processing unit, CPU). Background technique [0002] At present, in the face of the rapidly growing trend of globalization of streaming media information and network applications, enterprises and consumers require computer processors to provide more convenience and more obvious advantages, so the use of multi-core central processing unit (Central processing unit, CPU) ) of various servers came into being. A multi-core central processing unit refers to a central processing unit with more than two processor cores on a single central processing unit substrate. It is a new generation of computer central processing unit mainly for professional users or home multimedia users. Moreover, with the development of science and tec...

Problems solved by technology

These problems are caused by the fact that a single execution thread is scheduled by different CPUs in turn at runtime, and its time slices cannot be synchronized or cannot be called sequentially according to the design ideas.

[0006] In the test, the known test (Diagnostic) platform provides the function of assigning the entire process to a single central processing unit to run, but such processing can only minimize the occurrence of problems such as resource competition, and such processing will lead to Other CPUs are not under stress so not a good solution

[0007] Especially in some applications, such as: testing (Diagnostic), usually due to the characteristics of the test project or the characteristics of the hardware device, only one test execution thread is allowed to use a specific hardware device or the same resource at the same time. It will be easy for multiple execution threads to wait for requests

The above problems not only exist in the stress test of multi-core multi-CPU, but also exist in the normal multi-core multi-CPU computer system software call
