c thread pool

A thread pool program is written. Terminateallyarns is used to end the thread. This code is always stuck on the Interface every time.At first, I thought it was a code synchronization or mutex problem and I couldn't find it after half a day. So I tracked the original code and found that this code had led to an endless loop: ------------------ Idscheduler. Pas ----

The basic idea of the thread pool is also the idea of an object pool, which opens up a memory space in which many (not dead) threads are stored, and the thread execution schedule is handled by the pool Manager. When a thread task

When a task is submitted to the thread pool, how does the thread pool handle the task? This section looks at a referral poolThe main process flow, as seen in the process flow chart.It can be seen that when a new task is submitted to the thread

The role of the thread pool: The thread pool function is to limit the number of threads executing in the system.According to the environment of the system, can automatically or manually set the number of threads to achieve the best effect of the operation, less waste of system resources, many caused the system congesti

OverviewMultithreading is often used in our development. For example, in Android, because of the many limitations of the main thread, some time-consuming operations, such as network requests, we must run in a child thread. We tend to use the new thread to open a child thread, which is then switched to the main

Why use a thread pool? A thread is an operating system concept. The operating system is responsible for creating, suspending, running, blocking, and terminating operations on this thread. While the operating system creates threads, switches thread states, and ends up with CP

0. The need to use a thread pool? In a production environment, if you assign one thread to each task, you can cause many problems: the cost of the thread life cycle is very high. threads can be created and destroyed at a cost. For example, the creation of threads takes time and delays processing requests. If t

snatch it for use before the thread releases the resource. Loop wait (circular wait): Assume that n threads are running, the first thread holds a resource, and is waiting to obtain the resources held by the second thread, the second thread is waiting to obtain the resources held by the third

Some time ago, there was a project in the company that needed to be refactored, with the goal of improving throughput and usability, modifying the original threading model and processing logic in this process, and discovering that there are many basics of multithreading that are blurred, such as the operation of the underlying thread, the policies and logics of the existing thread

Benefits: Threads are scarce resources, if created indefinitely, will not only consume system resources, but also reduce the stability of the system, reasonable use of thread pool to uniform distribution, tuning and monitoring, there are the following benefits:1, reduce the consumption of resources;2, improve the response speed;3, improve the manageability of threads.The executor framework, introduced in Ja

destroying threads than on the actual user requests. The active thread consumes system resources in addition to the overhead of creating and destroying threads. Creating too many threads in one JVM can cause the system to run out of memory or "switch over" due to excessive memory consumption. To prevent the lack of resources, the server application requires some means to limit the number of requests processed at any given time. The

Definition of thread poolThe thread pool is a form of multithreading that adds tasks to the queue during processing, and then automatically starts those tasks after the thread is created. Thread pool threads are background threads
