关于pthread创建 [英] regarding pthreads creation

问题描述

大家好，
我正在做学期项目，在linux和Windows中对多线程性能进行基准测试.

在Linux中，我编写了一个简单的程序来创建线程，在那里我可以创建30,000个线程.
效果很好.

我编写了一个用于测量上下文切换时间的程序，并实现了用于测量上下文切换时间的乒乓游戏.
即使将堆栈大小设置为32kb，我也无法创建1000个线程.我要11！错误.
可能是什么原因.
谢谢.

Hi ALL,
Iam doing term project, Benchmarking multhreaded performance in linux andin windows.

In linux I wrote simple program to create threads, where I was able to create 30,000 threads.
It worked fine.

I wrote a program for measuring context switch time,I implemented ping pong game for measuring context switch time.
I am unable to create 1000 threads even if I set stack size to 32kb. Iam getting 11! error.
What might be the reason.

Thanks.

推荐答案

如果我没记错的话，Linux的线程数没有按进程的限制，而Windows的线程数没有限制.如果我没记错的话，逻辑会说Windows允许的进程中的线程数比Linux允许的线程数小得多.您可能应该查一下以进行验证.

If I remember correctly... Linux doesn''t have a per process limit on number of threads whereas Windows does. If I remember that correctly, logic would say the number of threads in a process allowed in Windows would be a lot smaller than that allowed in Linux. You should probably look that up though to verify.
