Abstract

The invention discloses a thread binding processing method and device, wherein the method comprises the steps of: judging whether the proportion that a first thread occupies the first kernel of a CPUis beyond a threshold value or not, wherein the CPU comprises multiple kernels; and the first kernel is one in the multiple kernels; when the proportion that the first thread occupies the first kernelis beyond the threshold value, judging whether a second thread also runs in the first kernel or not, wherein the second thread and the first thread are threads in the same process; and, when the second thread runs in the first kernel, determining whether the first thread or the second thread is bound to the second kernel in the CPU at least according to the proportion that the first thread occupies the first kernel, wherein the second kernel is one in the multiple kernels. By means of the thread binding processing method and device disclosed by the invention, the technical problem that the process fails to run due to too-high occupation of the CPU when different threads in the same process run on the same CPU kernel in the prior art can be solved.

Description

technical field [0001] The present invention relates to the field of computer software, in particular to a thread binding processing method and device. Background technique [0002] A program is an ordered collection of instructions and data, and a process is an execution of a program on a processor. Usually a process can contain multiple threads, and each thread is used as the basic unit of the central processing unit CPU. That is to say, a process is the smallest unit for the operating system to allocate resources (including but not limited to CPU, memory, disk, I / O, etc.), and a thread is the basic unit for CPU scheduling and allocation. For example, opening WeChat on a computer is a process, and opening a browser is a process. The multiple subtasks in WeChat, such as receiving messages and sending messages, are multiple threads under the process of WeChat. Since the process has an independent address space, after a process crashes, it usually does not affect other pro...
