title: How can Perl share global variables in parallel processing?
body: <pre><code>  use Parallel::ForkManager;
    use LWP::Simple;
    my $pm=new Parallel::ForkManager(10);
    our $a =0;
   @LINK=( 10,203, 20, 20 ,20 ,10 ,101 ,01 ,10 ) ;
    for my $link (@LINK) {
      $pm-&gt;start and next;
      my $lo = ($link * 120.22 )*12121.2121212121212121*( 12121212.1212121+ $link);
      $a = $a+ $lo ;   
      print $a."\n" ; 
      $pm-&gt;finish;
    };
  
    print $a ; 
  </code></pre>
