Experimental principle:I. Timing of dispatchDifferent types of processes have different scheduling requirements the first category: i/o-bound frequent i/o usually spends a lot of time waiting for I/O operations to complete CPU-bound nbsp COMPUTE intensive takes a lot of CPU time to do the second classification batch process (batch process) nbsp don't have to interact with us

Zombie Process: The child process terminated, but the parent process did not reclaim the resource PCB for the child process. Make it a zombie processOrphan process: The parent process ends with the child

Python concurrent Programming Multi-process 1.1 multiprocessing moduleMultithreading in Python cannot take advantage of multicore resources, and if you want to fully use the resources of multicore CPUs, most of the situations in Python require multiple processes. Python provides us with a very useful multi-process package multiprocessing!OS.CPU_COUTN ()The multiprocessing module is used to open sub-processe

Multi-tasking operating systemThe operating system provides a mechanism for the virtual processor, which gives the process an illusion that the process feels like it is monopolizing the CPU. The operating system kernel must pass reasonable process scheduling to ensure this illusion, so that the operating system resources to get the maximum utilization.It is this

Linux IPC (Inter-Process Communication, Inter-process Communication) pipeline learning, ipcinter-Process1. the standard Stream pipeline operation supports the file stream mode, which is used to create the pipeline linking another process. This blog introduces the function popen and pclosepopen in detail. 2. unknown pipeline (PIPE) features: 1) communication can o

/*--Handle Deadlocks View the current process, or deadlock process, and automatically kill the dead process Because it is for dead, you can only view the deadlock process if there is a deadlock process Of course, you can control through the parameters, regardless of whether

Soft test process, thread, management process comparison, soft test process thread In the operating system, I met three brothers, and it seemed like I had been dizzy for a long time. Today I figured it out, so I will dedicate this article to you who are still confused about the three brothers! Because they all have a process
