If Parallel::Queue's threading worked for me I'd suggest the following. use threads::shared;
use Parallel::Queue;
print concatenate_parallel( ['a' .. 'z'], 4 ) . "\n";
sub concatenate_parallel {
my $result :shared;
my @input = map {
my $string = $_;
sub {
$result .= $string;
};
} @{ shift @_ };
my $max_threads = shift @_;
my $mgr = Parallel::Queue->construct( 'thread' );
$mgr->runqueue( $max_threads, @input );
return $result;
}

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.
