Embodiment Construction

[0047] Hereinafter, some terms in the embodiments of the present application will be explained to facilitate the understanding of those skilled in the art:

[0048] JVM:

[0049] Java virtual machine (java virtual machine, JVM) is an abstract computer that runs all Java programs and is a running environment of the Java language. The Java virtual machine has its own complete hardware architecture, such as processors, stacks, registers, etc., as well as corresponding instruction systems. The Java virtual machine shields the information related to the specific operating system platform, so that the Java program only needs to generate the object code (bytecode) that runs on the Java virtual machine, and it can run normally on multiple operating system platforms without modification.

[0050] CPU:

[0051] The central processing unit (CPU) is a very large-scale integrated circuit. It is the core and control unit of a computer. Its function is mainly to interpret computer instructions and ...

Abstract

Embodiments of the invention provide a thread scheduling method and device, electronic equipment and a storage medium. The method comprises the steps of acquiring a pairing relation between each thread in a target virtual machine process and each local thread in an operating system; and according to the pairing relation, binding each thread to a corresponding processor in a target processor set, so that each thread is dispatched by the corresponding processor. According to the technical scheme, the phenomenon that time slices of the same processor are scrambled for when multiple threads are executed is avoided; the problem that multi-thread task queuing is blocked due to excessive service threads of the same processor and overlong service time of real-time threads is solved; the executiontime delay of other threads is shortened; and the real-time performance of thread execution is improved.

Description

Technical field [0001] This application relates to the field of computer technology, and in particular to a thread scheduling method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development of the Internet and mobile Internet, large concurrency and low latency have become the performance indicators of big data applications. Accordingly, in order to increase the amount of concurrency, multi-threading technology has been widely used in various applications. The advantages of performance and low power consumption have gradually become the mainstream of market servers. [0003] At present, in the Java virtual machine (java virtual machine, JVM) multi-threaded environment, threads mostly use preemptive scheduling to use the resources of the central processing unit (CPU), that is, the operating system allocates multiple threads to multiple CPUs , Each CPU allocates corresponding service time according to the priority of multiple threads...
