如何模拟C＃线程匮乏 [英] How to simulate C# thread starvation

问题描述

我试图诱使/事业线程不足，以观察在C＃中的作用。

I'm trying to induce/cause thread starvation so as to observe the effects in C#.

谁能好心建议可以创建一个（简单的）应用程序，从而导致线程不足？

Can anyone kindly suggest a (simple) application which can be created so as to induce thread starvation?

推荐答案

设置线程优先级和线程关联

Set thread priority and thread affinity

Worker类

class PriorityTest
{
    volatile bool loopSwitch;
    public PriorityTest()
    {
        loopSwitch = true;
    }

    public bool LoopSwitch
    {
        set { loopSwitch = value; }
    }

    public void ThreadMethod()
    {
        long threadCount = 0;

        while (loopSwitch)
        {
            threadCount++;
        }
        Console.WriteLine("{0} with {1,11} priority " +
            "has a count = {2,13}", Thread.CurrentThread.Name,
            Thread.CurrentThread.Priority.ToString(),
            threadCount.ToString("N0"));
    }
}

和测试

class Program
{

    static void Main(string[] args)
    {
        PriorityTest priorityTest = new PriorityTest();
        ThreadStart startDelegate =
            new ThreadStart(priorityTest.ThreadMethod);

        Thread threadOne = new Thread(startDelegate);
        threadOne.Name = "ThreadOne";
        Thread threadTwo = new Thread(startDelegate);
        threadTwo.Name = "ThreadTwo";

        threadTwo.Priority = ThreadPriority.Highest;
        threadOne.Priority = ThreadPriority.Lowest;
        threadOne.Start();
        threadTwo.Start();

        // Allow counting for 10 seconds.
        Thread.Sleep(10000);
        priorityTest.LoopSwitch = false;

        Console.Read();
    }
}

code主要来自 MSDN 此外，如果你有多核系统，您可能需要设置<一个href="http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/a55733db-cac0-4ccb-a3cc-a584742b41f9/">thread亲和力。您可能还需要创建多个线程，看看真正的饥饿。

Code mostly taken from msdn also if you have multicore system you may need to set thread affinity. You may also need to create more threads to see real starvation.
