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

[yangyu <ya...@hp...>]

Good morning Agustin,
Good morning everyone,


Thank you very much for the information you gave to me.
I am happy to hear that the speed of PEs can be changed when the simulation
is running.

I just tried one way to  change the speed of PEs. It seems that it does not
work .(Forgive me if I chose a wrong way to write the code) I am not sure
the method I used is right or not.
  Can you tell me why I can not change the speed(rating) of PEs when you are
not busy?

Thank you very much.

PS. I found that in the  Class ResourceCharacteristics, the method
setResourceID(int id) does not work.(I can not make resources ID as I want
them to be.)

 (I am sorry that I sent this question  to "GridSim-users] help regarding
compiling.............". 10minuts ago.I am so sorry about that.)

bestwishes,
yang,

_/*I  ran this program step by step to see "rate"and "rate_change".I found
that they were same*/

    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 using the method that I know*/
  for(int i=0;i<num;i++) {
                                  pelist.add(new PE(i,1000));

         String os = "Solaris";          // operating system
         double time_zone = 0.0;         // time zone this resource located
  ResourceCharacteristics resource = new ResourceCharacteristics(
                    arch, os, mList, ResourceCharacteristics.SPACE_SHARED,
time_zone, 1);

// PEList pelist1=resource.getMachineList().getMachine(0).getPEList();
/* to check that they are changed or not*/
                       for(int i=0;i<num;i++)
                              {
                              // rate_changed=pelist1.getMIPSRating(i)
                               rate_changed=pelist.getMIPSRating(i);
//rate_changed is same as rate.
                              }
}
