Reprinted from http://blog.csdn.net/tigerjb/article/details/6007073 We learned how to create a process through the fork () function and vfork () function. Now let's continue to learn two special processes: orphan process and daemon process.1. Orphan Process1. What is an orphan process?If the parent

Process /*--Handle Deadlocks View the current process, or the deadlock process, and automatically kill the process Because it is dead, so if there is a deadlock process, only the deadlock process can be viewedOf course, you can co

Linux supports multiple processes at the same time, which is what we often call multi-channel programming in modern operating systems, so-called at the same time the Linux system scheduling each process to occupy the CPU. Because each time slice time is very small and macroscopic time compares, gives the person the feeling is the multi-process is running. In order to improve the running efficiency of the pr

a process is a core concept of the operating system. Each process has its own unique identity: The process ID, and its own life cycle. The life cycle of a typical process is shown in 4-1. The process has a parent process, and th

Let's look at the example of a parent process sending a kill signal to a child process:#include Macro that determines the status of the child process exit:the end state of the child process is returned and stored in status, with several macros at the bottom to determine the end conditionwifexited (status) is a non-0 va

This article was reproduced from: http://www.cnblogs.com/youngforever/p/3250270.htmlThese two days to see the process of synchronization and communication, read a few books on the introduction, but also from the Internet search a lot of information, the more confused, the more puzzled by these issues are very tangled. What is the difference between process synchronization and mutex? What are th

In Python, because of the existence of the global interpreter lock Gil, the multithreading in Python does not significantly improve the efficiency of the program (in this case, CPU-intensive), then in the processing of CPU-intensive computing, multi-process model to deal with, The multiprocessing library is available in the Python standard library to support the programming of multi-process models. The

Today, to help people solve the problem, with VB.net wrote a paragraph based on the process name to find the PID method.Previously used in the VB6 accumulation of APIs to play a role, mainly in the VB.net processing API declaration Notice to change all long to integer, and if any, you need to change to object.The VB6 long corresponds to the vb.net integer. If you mix it up, you'll get an error.Now that you've written it, just record it and make it eas

A sub-process means that a new process can be created and executed during a process flow, where the parent process can be returned at the end.about sub-processesSub-processA sub-process is a BPMN component, which is a composite activity in a

In the previous chapters we learned that there is a correlation between processes: Each process has a parent process; When a child process exits, the parent process can perceive and get the exit status of the child process. In this chapter we will look at:

After starting Hadoop and then starting Spark JPS, the master process and worker process are found to be present, and a half-day configuration file is debugged.The test found that when I shut down Hadoop the worker process still exists,However, when I shut down spark again and then JPS, I found that the worker process
