[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,
---------the code--------------------------------------------------
_/*I  ran this program step by step to see "rate"and "rate_change".I found
that they were same*/
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 using the method that I know*/
  for(int i=0;i<num;i++) {
                                  pelist.add(new PE(i,1000));

			//      PE pe=new PE(i,1000);
			//      pe.setMIPSRating(1000);
  			}
  MachineList mList = new MachineList();
  mList.add( new Machine(0, pelist) );
  String arch = "Sun Ultra";      // system architecture
         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();

                       for(int i=0;i<num;i++)
                              {
                              // rate_changed=pelist1.getMIPSRating(i)
                               rate_changed=pelist.getMIPSRating(i);
//rate_changed is same as rate.

Good morning Yang Yu,

Regarding the resource id, you should not change it, as it is Gridsim 
who decides the id for each entity in a simulation.

If you really need to have a kind of id which you yourself can set, you 
can add a new parameter in the resource class (and call this new 
parameter, for example, my_id). This way you can use the my_id of 
resources (or any entity you want) to do all your stuff, whilst keeping 
the same GridSim's id (which is essential for GridSim to work).

Regarding changing the speed of PEs, I'm sorry but I've not been able to 
look into it.

All the best,

Agustin

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

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

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

Hello Dear Agustin,

 Thank you very much for you kindness and  your help to me.
 I just had a try. I found that there is some problem in that code.
------------------------------------------
 for(int i=3D0;i<num;i++) {      =20
	// get a PE of this resource=20
	// something like:
	// pe=3D pelist.get(i);    =20
	// then change the rating
	pe.setMIPSRating(1000);  	=09
  }
------------------------------------------
The prolem is with the code "pe.setMIPSRating(1000);"  when compling .
some information like "pe is not defined symbol" was shown.

To work out this, at the head of my class I wrote "public static PE pe;  =
" (I am not sure of it, just a try).

and the Compling is passed, but when it run to the code =
"pe.setMIPSRating(1000); ", the program will be stopped and throws a =
message of "java.lang.NullPointerException".

I thought that when the excution of program runs to   " =
pe.setMIPSRating(1000);"  to set the PE with a new_speed, maybe Program =
can not know  which PE`s speed is going to be re-setted. (As the message =
of NullPointerException) .

And I  also tried to use " pe=3D pelist.get(i);" , but a error message =
like "java.lang.Objct can not be setted as  gridsim.PE" was shown.


I really want to say "Thank you very much for your help to me. you are =
so kind", though I can not run your code correctly.


I will go on to find how to change the performance(speed of PE).


And if you have some new information about change speed of PE,  I `d =
like to read and try it.


Thanks a lot,

best wishes to you.


Yang Yu

Hello Yang Yu,

I've just taken a look at your example, and I'm afraid that what you do=20
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=3D0;
    int rate_changed=3D0;
    PEList pelist=3Dresource.getMachineList().getMachine(0).getPEList();
    int num=3Dresource.getNumPE();


   /*to see the rate of PEs before change them. there were 6PEs and each =
PE~s
   speed is 200*/
  for(int i=3D0;i<num;i++){
     rate=3Dpelist.getMIPSRating(i);
   }

  /* try to change speed to 1000 */
  for(int i=3D0;i<num;i++) {      =20
	// get a PE of this resource=20
	// something like:
	// pe=3D pelist.get(i);
	// then change the rating
	pe.setMIPSRating(1000);	=09
  }



  /* to check that they are changed or not*/
 =20
  for(int i=3D0;i<num;i++)
  {
         rate_changed=3Dpelist.getMIPSRating(i);
	//rate_changed is same as rate.
  }
}


Tell me if this works,

Agustin

Of course, pe must be declared before being used. I think that  "public 
PE pe; "  is ok.

Of course, before trying to set the speed of a PE, you must decide which 
PE you want to set. In order to do that, you must go through the PEList, 
which is what I meant in the code I sent you. Probably the failure is 
that "pelist.get(i); " returns a Object, so try doing a casting to PE, 
such as "pe= (PE) pelist.get(i);".

Hope this helps,

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

[<smp...@ya...>]

Dear Agustin,
   
   Good morning..
   
   I am so happy to tell you that the code can change the speed of PEs !!
   Thank you very much for your help ! !
   
   With your help , I can change PE_speeds as I want to, during simulation.
   
  (PS: I am now at home, So I can not use the mail_address that I used. But I want to tell you about it immediately  )
   
   
  Thank you very much.
   
  Good luck to you and have a nice weekend.
   
   
  yours,
   
  Yang,

Dear=E3=80=80Agustin

=E3=80=80Good afternoon.

=E3=80=80I=E3=80=80Sent a mail to you=E3=80=80and to this mailing list =
on Sunday .Because I was at home ,So=E3=80=80I used an other mail =
address.
=E3=80=80I am afraid that you may not read it So=E3=80=80I Want =
to=E3=80=80Say thank you and tell you that The code you told me can work =
well.=E3=80=80

=E3=80=80Thank you very much
=E3=80=80Best wishes,


=E3=80=80Yours,

Of course, pe must be declared before being used. I think that  "public=20
PE pe; "  is ok.

"pe.setMIPSRating(1000); ", the program will be stopped and throws a =

can not know  which PE`s speed is going to be re-setted. (As the message =
of NullPointerException) .

Of course, before trying to set the speed of a PE, you must decide which =

PE you want to set. In order to do that, you must go through the PEList, =

which is what I meant in the code I sent you. Probably the failure is=20
that "pelist.get(i); " returns a Object, so try doing a casting to PE,=20
such as "pe=3D (PE) pelist.get(i);".

Hope this helps,

Agustin
