These days suddenly interested in the association process, so that they achieved a, the code on GitHub: Https://github.com/adinosaur/CoroThe process is a non-preemptive thread of user space, which is mainly used to solve the problem of waiting for a large number of IO operations.Co-process vs threadCompared to the use of multithreading to solve the IO blocking task, the advantage of using the co-operation is not to lock, access to the shared data with

Imitation of the cloud-wind libraries interface design, I spent an afternoon and evening to reconstruct the previously written libraries, the interface is now the same as the cloud wind greatly the interface of the coprocessor, are imitation of Lua asymmetric process. We still do not use the Ucontext.h component (with ucontext.h components to achieve the association of articles overwhelming, you can find yourself, with longjmp implementation of a lot less, with inline assembly to achieve less),

Co-process (fiber, micro-threading) This concept has long been, the Internet companies have also studied, but in the domestic major forums and the conference hot up, or this year's events.Recently involved in the discussion of open platform construction and architecture design, some colleagues mentioned that using the co-process instead of threading can greatly improve performance. This has led to great int

. Process Pool3.1 What is a process pool?The process pool maintains a sequence of processes that, when used, gets a sequence of processes in the process pool, and if there are no process sequences available for use in the process pool, the program waits until a sequence of processes is available in the process pool.3.2:　　　　　　There are several main methods in the process pool:Apply: Take a process from the process pool and executeAsynchronous version of Apply_async:apply, once taken out and then

Python in co-processTalk about Python processes and threads before you elicit the concept of co-formation.Process:The process is executing a program instance. During the execution of the program, the kernel will tell the program code to load virtual memory, allocate space for program variables, and establish bookkeeping data structure to record process-related information.such as process ID, user ID, and so

1 concept of co-process 1.1 co-processCo-process, also known as micro-threading, fiber. English name Coroutine. One sentence explains what a thread is: The process is a lightweight thread that is user-state . (In fact, it does not indicate white ~)I think that the association process, more abstract, if the thread has a certain understanding, it should be better understood.　　So it's easier to understand the

This is a creation in Article, where the information may have evolved or changed. The phone interview was asked to go to the association, once the military Wei also asked me about the process. Although in Python time in Eurasia and Eventlet understand the association, but their concept of the association is a lightweight thread, there is a very popular traffic lights saying: thread to keep the rules, the co-process see red light but no car can still p

Co-processCo-process, also known as micro-threading, fiber. English name Coroutine. One sentence explains what a thread is: The process is a lightweight thread that is user-state. The co-process has its own register context and stack. When the schedule is switched, the register context and stack are saved elsewhere, and the previously saved register context and stack are restored when it is cut back. So:The

Disclaimer: I have all the works, prohibited for marketing purposes of any reprint!ObjectiveA long time ago I heard that Python's async/await is very powerful, but it has not been used until now and has been using multithreaded models to solve various problems. Recently saw the Go next door is very hot, so decided to take the time to study the Python process related content, and finally after looking through a underwear of the material has some understanding.Up: Everything starts with the genera

Co-process, also known as micro-threading, fiber. English name Coroutine.subroutines, or functions, are hierarchical calls in all languages, such as a call to b,b in the execution of a call to C,c execution complete return, b execution is finished, and finally a executes.So the subroutine call is implemented through the stack, and a thread is executing a subroutine.Subroutine calls are always one entry, one return, and the call order is clear. And the
