language level of lightweight processes is less, stackless Python,erlang support, Java is not supported. Third, the co-process What is the definition of a co-process? Outskirts, Xu Xiwei are only said to be a lightweight thread, a process can easily create a hundreds of thousands of-meter association. Careful study, the personal feeling that these are the myth of people. From Wikipedia, the "subroutine is

Python programming.The life cycle of the generator:Gen_creaated #等待开始执行Gen_running #解释器正在执行 (This state is only visible in multi-threaded applications)gen_suspended #在yield表达式处暂停Gen_closed #执行结束* * co-processA process is a computer program component that produces subroutines for non-preemptive multitasking, allowing different entry points to pause or start executing programs at different locations.By using yield pause generator, the process can pass

The effect that the process can achieve is to execute the code that needs to execute at a specified point in time, the function that starts a co-process in unity is Startcoroutine, and the classes that provide the delay are the following: New Waitforendofframe; Wait for a frame new Waitforfixedupdate; Wait for a fixedupdate (fixed interval) new Waitforseconds; Wait x seconds new WWW;

process, not stable enough, easy to lose data.The process is a kind of user-state lightweight thread, the scheduling of the association is completely user-controlled. The co-process has its own register context and stack. When the scheduling switch, the register context and the stack is saved to another place, in the cut back, the recovery of the saved register context and stack, the direct Operation Stack is basically no kernel switching overhead, c

thread can create and revoke another thread, which can be executed concurrently between multiple threads in the same process. Because of the mutual constraints between threads, the thread is running in a discontinuous. Threads also have three basic states of readiness, blocking, and running . A ready state is a thread that has all of the conditions running, is logically capable of running, is waiting on a processing machine, and a running state is a thread-owning processor that is running; a bl

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
