Re^5: Multythread script. The best way.

I need to distribute cpu-intensive numerical calculations over multiple cores. In fact it is not math calculation rather it is check for compliance with a number of attributes (about 100).

Then forget Coro, or the event driven frameworks.

Concentrate on threads and Parallel::ForkManager.

The decision between those two is: in part elective; in part platform dependent; but mostly will centre upon the details of your iterations.

eg. if the logical approach is to run 100 passes (not all concurrently) over the entire dataset I might use one approach. On the other hand if it makes more sense to perform 1 pass over each of a number of subsets I'd use another.

I'd need more info to choose which.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

Thanks again. I already have read about threads and Parallel::ForkManager. And decide that my way is Parallel::ForkManager. So it time to do my work.	[reply]
