If your Perl is not built with threads support, no problem. GrandFather's queue demonstration is possible using MCE::Hobo and MCE::Shared. Notice the similarity.
use strict;
use warnings;
use MCE::Hobo;
use MCE::Shared;
my $workQueue = MCE::Shared->queue();
my $doneQueue = MCE::Shared->queue();
my $numWorkers = 4;
MCE::Hobo->create(sub{DoWork($workQueue, $doneQueue)}) for 1 .. $numWo
+rkers;
for (1 .. 10000) {
my $work = int(rand(10000));
$workQueue->enqueue($work);
}
$workQueue->end();
my $count_done = 0;
while () {
my $result = $doneQueue->dequeue();
last if (!$result && ++$count_done == $numWorkers);
print "$result\n" if $result;
}
$_->join() for MCE::Hobo->list;
exit;
sub DoWork {
my ($work, $done) = @_;
while (my $item = $work->dequeue()) {
$done->enqueue($item) if $item >= 10 && $item <= 20;
}
$done->enqueue(0);
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
