17.1 ThreadsAll threads are the same for Windows, but MFC divides the thread area into two types: User Interface (UI) threads (UI) and worker threads (worker threads).The difference between the two threads is that the UI thread has a message loop

There are many scheduling algorithms in the operating system, some of which are suitable for job scheduling, some scheduling algorithms are suitable for process scheduling, and some scheduling algorithms are applicable. Here are a few common

The translation is as follows:1.1 Linux Process ManagementProcess management is one of the most important functions of the operating system. Efficient process management can ensure a smooth and efficient operation of a program.Linux process

Objective:VPS universality is not high, many people may have such a feeling, in the implementation of DU, tar and other commands, will cause the system load soared, Apache response slow. This can be mitigated by the nice command changing the process

This article describes the performance testing of Linux comes with commands, detailing the use of these Linux-brought tools.First, uptimeThe results of the uptime command include how long the server has been running, how many logged-in users, and

First, prefaceThe Linux scheduler is mysterious and tempting, and every Linux engineer wants to dive into its interior. But there is an old adage in China called "The Heart of Life", a module of ingenious internal logic (the so-called "heart") whose

The CONTEXT structure plays an important role in thread scheduling. In all WINDOWS-defined structures, CONTEXT is unique dependent on the CPU. We can call GetThreadContext to obtain the status of the current CPU register. BOOL GetThreadContext(

The procedure in progress is called a process. When a program is stored in an executable file and runs, each process is dynamically assigned system resources, memory, security attributes, and the state associated with it. Multiple processes can be

1. context switching: around 20 ms (you can use the second parameter of the getsystemtimeadjustment function for details). Windows displays all existing thread kernel objects. only some of these objects are considered to be schedulable. windows

################### # # Process Definition # # ###################Whenever an event is triggered, the system defines it as a process and gives the process an ID, called the PID.Process is the work that the CPU does not complete*) distinguish
