Hi browserUK,

is there some problem in the below code :-

use strict;
use threads;
use threads::shared;
use Thread::Queue;

my @clientList =  qw(
    client1 client2 client3 client4 client5 client6
    );
my @queryList = qw(
    query1 query2 query3 query4 query5 query6
    );
my $maxnoofQueryThreads = 15;
my $maxnoofCompThreads = 30;
    
     my $globalQ = new Thread::Queue;
     my $queryBossID = threads->new(\&queryBoss,$globalQ);
     my $compBossID  = threads->new(\&compBoss,$globalQ,);
            
            $queryBossID->join;
            $compBossID->join;
            
sub queryBoss
 {
  my $q = new Thread::Queue;
                my $globalQ = shift;
                my @queryworkers = map {threads->new( \&queryworker, $
+q,$globalQ);} 1 .. $maxnoofQueryThreads;
                $q->enqueue(@queryList);
         $q->enqueue( ( undef ) x $maxnoofQueryThreads );
         $_->join for @queryworkers;
        }
sub compBoss
 {
  my $globalQ = shift;
  my @compworkers = map {threads->new( \&compworker, $globalQ);} 1 .. 
+$maxnoofCompThreads;
                #$q->enqueue(@queryList);
                $globalQ->enqueue( ( undef ) x $maxnoofCompThreads );
  $_->join for @compworkers;
 }
sub compworker
 {
  my $globalQ = shift;
  my $tid = threads->self->tid;
  while(my $workItem = $globalQ->dequeue)
   {
    print " the file is $workItem \n";
    #start comparison on the file and dump result in a new file and de
+l the file
   }
 }
sub queryworker
        {
              my( $Q ) = shift;
              my $globalQ = shift;
              my $tid = threads->self->tid;
              while( my $workItem = $Q->dequeue ) 
            {
    for( my $i = 0; $i < @clientList; $i++)
   {
                    #lock $mtxStdOut;
                    print " workitem  from thread $tid -->$workItem\n"
+; 
    ## Perform query
           ## worked on one client for query signal compBoss to start 
+doing comp
                                ## so enqueue the file location on dum
+p
    my $fileLoc = "$workItem"."$clientList[$i]";
    $globalQ->enqueue($fileLoc);
   }
            }
        }
