Create 1000 threads in linux

Create 1000 threads in linux-general Linux technology-Linux programming and kernel information. For more information, see. To create 1000 threads, run ulimit-s 2048 first.

It is almost impossible to solve this problem using a program.

According to the posix thread of RedHat Linux 9.0, the parent process of each thread is the current console process, rather than the process that calls pthread_create. On the other hand, the number of threads that can be created in a process is mainly limited by the stack size: 2G/maximum stack size allowed, on the i386 platform, the maximum stack size of the console process is 8 MB by default, so the number of threads that can be created is 2G/8 M = 256. However, the 8 m limit can be modified by running the ulimit command to indirectly increase the number of threads that can be created.

In this way, your question evolves to "can you modify the maximum stack size parameter of the console process through a program ?". I personally think this is difficult to achieve through conventional methods.

Modify ulimit Parameters

[Root @ web230 ~] # Ulimit-n
1024

Take limit-n as an example.

Vi/root/. bash_profile

Add ulimit-HSn 10240 to save and exit

Source/root/. bash_profile

[Root @ web230 ~] # Ulimit-n
10240
