in thread Converting a parallel-serial shell script
I think you have failed to see the motivation behind my post. I just wanted to share my thoughts and experience in approaching this type of problem. And that is why I haven't given a code example. It is probably my fault because of the way I have expressed myself but Corion seems to have got it right.
Your solution proves me wrong. It is neat and elegant and I really like it. But I still think that I make good points when considering the problem of parallelization in more general terms.
Finally, you could perhaps shed some light on how what I am talking about is not scalable - after all you could fork as many processes as you need. Portable? I am not sure how portable fork and semaphores really are. Though, fork() works for me on Windows with ActivePerl, it appears to be using threads behind the scenes, so does that mean that you the speed benefits of threads without the disadvantages of having to be careful with shared data? Efficient? I don't think that there will be a noticeable difference between a forking and a threading implementation.
