hello all, i am getting the following error when i am trying to run my 1st Perl script: 
[id=0 @ 0] : IP address "3.3.3.3" corresponds to device "core". 
Thread 1 terminated abnormally: Not a CODE reference at ./dev_ithread.
+pl line 23.
[id=0 @ 1] : IP address "5.5.5.5" corresponds to device "border".

and here is what i have written so far: 
#!/usr/bin/perl

use    strict ;
use    warnings ;
use    diagnostics ;
use    threads ;
use    Config ;

$Config{useithreads} || die("\n---> Please recompile Perl with \<ithre
+ads\> included. \n") ;


# IP parameterization of network elements.
my %device_ip = ( 
            "core" => "3.3.3.3",
            "border" => "5.5.5.5",        
        ) ;

# Initialize devices' pool of threads.
my $index = 0 ;
my @device_thread = () ;
while( my ($key, $value) = each %device_ip )    
{ 
    push( @device_thread, threads->new(\&thread_job($key, $device_ip{$
+key}, $index))->join ) ;    $index = $index+1 ;
}

# Worker thread subroutine.
sub thread_job
{
    my ($device, $ip, $index) = @_ ;

    my $ithread = threads->tid() ;
    print "[id=$ithread @ $index] : IP address \"$ip\" corresponds to 
+device \"$device\". \n" ;
}
