You can share data between two processes spawned by any forker, or threads, using MCE::Shared. See many nodes here at the monastery by marioroy, author of MCE -- for example this demonstration.

Here's an example of some code I use to push to a shared array from multiple workers that are also managed by MCE: 

use MCE::Loop;
use MCE::Candy;

my $shared = [ ];
MCE::Loop::init(
    max_workers => $CONFIG->max_workers_MCE,
    chunk_size  => 100,
    gather      => MCE::Candy::out_iter_array( $shared ),
);

mce_loop {
    my ( $mce, $chunk_ref, $chunk_id ) = @_;
    my @items_to_gather;

    foreach my $item ( @{ $chunk_ref } ) {
        push @items_to_gather, $item; # your logic here
    }

    MCE->gather( $chunk_id, @items_to_gather );

} @list;

Hope this helps!


The way forward always starts with a minimal test.
