Subject: Is there a return mechanism for MCE?
Date: Fri, 15 Aug 2014 10:50:06 -0400
To: "bug-MCE [...] rt.cpan.org" <bug-MCE [...] rt.cpan.org>
From: Frank Wang <frank.wang [...] validusresearch.com>
Hi Mario, Thank you for your MCE module. I tried it recently while my code using Parallel::Loops in strawberry-perl 5.18.2.1 no longer work (which only have one worker active no matter how we set that number). The MCE works perfectly with as much as wanted workers active and even when using one worker it is faster than Parallel::Loops. There is one problem while change to use MCE: in Parallel::Loops there is a share function to pass result back to parents via %hashes or @arrays. I cannot find a similar or replacing mechanism to return back results to parents in MCE. Or there are ones but I just not find them in the documents or examples? Thank you for your attention.

Hi Frank, Have a look at MCE::Loop. https://metacpan.org/pod/MCE::Loop#GATHERING-DATA use MCE::Loop chunk_size => 1, max_workers => 8; The do and gather methods are described here. These methods send data back to the main process and can be called as often as needed. https://metacpan.org/pod/MCE::Core#METHODS-for-WORKERS-only Their is also MCE::Map if wanting to pass data transparently without having to call on ->do or ->gather. https://metacpan.org/pod/distribution/MCE/lib/MCE.pod#MCE-MODELS Let me know if you run into any problems. Mario

Hi Frank, I am resolving this ticket (not a bug). MCE has a return mechanism through MCE->do and MCE->gather. Please feel free to email me at marioeroy @ gmail dot com. Kind Regards, Mario
