Hi Ye,

Please change this part of the code:

---------------------------------
     		if (ev.get_tag() == GridSimTags.GRIDLET_RETURN){
     			gridlet = (Gridlet) ev.get_data();
     			super.recordStatistics("[ticking]: Received grildet: " +  
gridlet.getGridletID() + " from " +
                         resourceName + "\"",  
gridlet.getProcessingCost());

                 // stores the received Gridlet into a new  
GridletList object
                 this.receiveList_.add(gridlet);
             }
---------------------------------
to:
---------------------------------
     		if (ev.get_tag() == GridSimTags.GRIDLET_RETURN){
     			gridlet = (Gridlet) ev.get_data();
     			super.recordStatistics("[ticking]: Received grildet: " +  
gridlet.getGridletID() + " from " +
                         resourceName + "\"",  
gridlet.getProcessingCost());

                 // stores the received Gridlet into a new  
GridletList object
                 this.receiveList_.add(gridlet);

                 if(receiveList_.size() == list_.size()) {
                 	break;
                 }
             }
---------------------------------

Otherwise your simulation will never end and you will get those  
errors. Also, I am sorry, but I could not understand what you want to  
do in this part of the code:

-------------------------------
  boolean resubmit = true;

         // a loop to get one Gridlet at one time and sends it to a grid
         // resource entity. Then waits for a reply
         for (int i = 0; i < this.list_.size(); i++)
         {
             gridlet = (Gridlet) this.list_.get(i);
             info = "Gridlet_" + gridlet.getGridletID();

             System.out.println("Sending: " + info + " to " +  
resourceName +
                     " with id = " + resourceID);

             // Sends one Gridlet to a grid resource specified in  
"resourceID"
//            super.gridletSubmit(gridlet, resourceID);

             // OR another approach to send a gridlet to a grid  
resource entity
             super.send(resourceID, GridSimTags.SCHEDULE_NOW,
                   GridSimTags.GRIDLET_SUBMIT, gridlet);

             if(resubmit) {
             	LinkedList ll = createGridlet( this.ID_.intValue() );
             	for(int k = 0; k < ll.size(); k++) {
             		this.list_.addLast(ll.get(k));
             	}
             	
             	resubmit = false;
             }

----------------------

resubmit will be true initially, which will make "inkedList ll =  
createGridlet( this.ID_.intValue() );" create a new list of gridlets  
with the same ids of the gridlets that are already in list_.

Marcos
