Re^4: Multythread script. The best way.

0. Yes 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).

1. No it is no final step. Each thread shuld upload satisfying result to DB (MySQL).

2. I'll looking to run it on one muli-cored box. But I'd like idea about several computers in calculations. Seems it will be next step, next time.

Thank you for your involvement

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. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

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]
