Re: [GridSim-users] about dynamic performance. and a question of setting resourceID

[<ag...@ds...>]

Hello Yang Yu,

I've just taken a look at your example, and I'm afraid that what you do 
is not correct.
I mean, you are not changing the rating of PEs, but just creating new PEs.

So, try doing this:

public void changePE(){
    int rate=0;
    int rate_changed=0;
    PEList pelist=resource.getMachineList().getMachine(0).getPEList();
    int num=resource.getNumPE();


   /*to see the rate of PEs before change them. there were 6PEs and each PE~s
   speed is 200*/
  for(int i=0;i<num;i++){
     rate=pelist.getMIPSRating(i);
   }

  /* try to change speed to 1000 */
  for(int i=0;i<num;i++) {       
	// get a PE of this resource 
	// something like:
	// pe= pelist.get(i);
	// then change the rating
	pe.setMIPSRating(1000);		
  }



  /* to check that they are changed or not*/
  
  for(int i=0;i<num;i++)
  {
         rate_changed=pelist.getMIPSRating(i);
	//rate_changed is same as rate.
  }
}


Tell me if this works,

Regards,

Agustin
