PERL parallel multi threading

Question

I am writing a PERL script involving multithreading. It has a GUI and the number of threads to be used will be taken as user input. Depending on this number, the script should generate threads which all access the same sub. I want the n threads to work in parallel. But when I create a loop, the parallel processing is lost. Any idea as to how to overcome this issue?

Answer 1

I believe that the simplest way to answer would be to recommend you to look at something like POE . The framework cookbook webpage provides many examples that surely will be a good starting point for your original issue.

Depending on your GUI platform, you may also want to spend time on event loops provided by the framework itself.

Answer 2

You probably need to call threads->yield() function occasionally in the processing loops. The yield() function gives a "hint" to give up the CPU for a thread.
