Re: [GridSim-users] java runtime exception message

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

Are you sure you are using Sun's Java ?

Any version newer or equal to 1.4.2 is ok.

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,

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

[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,

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

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

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

[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.)

Hello YangYu,

Sorry for the late reply, but I've been busy these days.

I think that what you say can be done in a similar way as the resource=20
failure functionality.
This is, computing resources could change the speed of their PEs in=20
response to an event.

If you do this, you should consider the allocation policy in place, as=20
in the body function of the space-shared allocation policy the rating of =

the PEs of the resource are retrieved.

So, more concretely, the GridResource class should receive the event=20
(perhaps the event could be sent by the GIS, as in the resource=20
failure). Then, update the PE class with the new rating by going through =

the ResourceCharacteristics class, to the MachineList, to the PEList=20
until you get to the actual PE you want to modify. If you use=20
SpaceShared policy, update the PEs rating also in this class.

Normally, allocation policies consider that all the PEs of the same=20
machine are identical, so you should take it into account when changing=20
the PE rating, and keep it always like that.

Hope that this is useful. Do not hesitate to ask again if you still have =

doubts.

Regards,

Agustin

Re: [GridSim-users] help regarding compiling.............

[Srikumar V. <sri...@gm...>]

Hi,
   You dont need to use IDEs however it would help a lot if you did.
If you have downloaded and installed Sun JSDK, ensure that :
1. GCJ is not in the path
$ which java
    should return the path of Sun's Java binary.
2. Your classpath is set.
     Like an earlier email said, ensure that the two jars (gridsim and
simjava) are in your classpath.
$ export CLASSPATH=<path>/gridsim.jar:<path>/simjava.jar
     where <path> is the directory in which you have put the jar files

Run again. Go over the instructions provided in the GridSim
distribution. They are pretty detailed.

On an unrelated note, I noticed earlier that you are running java in
the root account. While this has *no effect* on GridSim's performance,
it is generally a good idea (security-wise) to execute *all* programs
from a user account.

Cheers

Sri.

shell. Is dat i need to use any special IDE's to work with this gridsim tool
and if so please help get me the exact steps of how to work with this tool.
I m using Centos 4. I ve also installed JSDK as said by Srikumar Venugopal.

Re: [GridSim-users] help regarding compiling.............

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

Hello,

In the web site of GridSim (http://www.gridbus.org/gridsim/) there are 
instructions on how to use GridSim with Eclipse 
<http://www.gridbus.org/gridsim/paper/eclipse.pdf> or JBuilder 
<http://www.gridbus.org/gridsim/paper/jbuilder.pdf> or JCreator 
<http://www.gridbus.org/gridsim/paper/jcreator.pdf>. I think all of them 
have free versions.

Regards,

Agustin

Re: [GridSim-users] help regarding compiling.............

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

good evening.
I just guessed that your setting of the path of gridsim.jar and simjava.jar
may be not done. (or other path of java library.)
I am uesing A soft named NetBeans IDE 5.0, you can set library easily when
using it. You can get if for free.
Hope to help you.
good luck,

yours,

Re: [GridSim-users] To dear Agustin, To dear All ( a question bout GridSim )

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

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 am sorry that I am not in school now so I have to use my PC mail-address this time.
   
   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.
   
   
  bestwishes,
  yang,
  --------------------------------------------------
  _/*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,100);
//      pe.setMIPSRating(1000);}

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

I think that what you say can be done in a similar way as the resource 
failure functionality.
This is, computing resources could change the speed of their PEs in 
response to an event.

If you do this, you should consider the allocation policy in place, as 
in the body function of the space-shared allocation policy the rating of 
the PEs of the resource are retrieved.

So, more concretely, the GridResource class should receive the event 
(perhaps the event could be sent by the GIS, as in the resource 
failure). Then, update the PE class with the new rating by going through 
the ResourceCharacteristics class, to the MachineList, to the PEList 
until you get to the actual PE you want to modify. If you use 
SpaceShared policy, update the PEs rating also in this class.

Normally, allocation policies consider that all the PEs of the same 
machine are identical, so you should take it into account when changing 
the PE rating, and keep it always like that.

Hope that this is useful. Do not hesitate to ask again if you still have 
doubts.

Regards,

Agustin

[GridSim-users] To dear Agustin, To dear All ( a question bout GridSim )

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

hi,Thank you for your help !!
It took me time to read and run the examples.
I am sorry to re-mail you late,infact I do not know how to explain my doubts
to you by this mailing list.

I want to chage the speed of PEs or machines dynamicly.
for example,change a pe`s rating from 100 to 500  when the simulation is
running.
Not to mean that make the machine down(speed/performance=0?).

Thank you very much .


yours,


Hi,

When you say dynamic performance, what do you actually mean?

Because since the current (4.1) version of GridSim, computing resources
may  fail. This is, machines belonging to computing resources may work for
some time, then stop working for some  time, and then back again to work.

Thus, the performance of the computing resources may change dynamically,
if you use this computing resource failure functionality.

For instructions on how to use this functionality, please take a look at
http://www.gridbus.org/gridsim/example/resFailure_index.html
where there are examples on how to use it.

Also, take a look into these addresses:

http://www.gridbus.org/reports/GridSim-FailureHandling-2007.pdf

September 2007


The Gridbus Project at The University of Melbourne, Australia has released 
the
next-version of Grid simulation software, the GridSim Toolkit 4.1.

The new version of GridSim adds a new functionality that supports
resource failures and failure detection of Grid resources. This work was 
done
in collaboration with Agustin Caminero, a Phd student from
Universidad de Castilla La Mancha (UCLM), Spain.

All components developed as part of the GridSim Toolkit are released as
"open source" under the GPL license to encourage innovation and pass full
freedom to our users. In addition, we have decided to use
SourceForge (http://sourceforge.net/projects/gridsim) for hosting
our future releases and developments. This allows us to share and
and to collaborate further on new functionalities.
Therefore, contributions to the GridSim Toolkit are greatly appreciated.

The early version of our GridSim toolkit has been used/dowloaded by 
several
academic and commercial organizations around the world including:
University of Southern California (USA), California Institute of 
Technology (USA),
Argonne National Labs (USA), University of Manchester (UK), CERN,
Universidad de Santiago de Compostela (Spain), Indian Institute of 
Technology,
Tsinghua University (China), Sun Microsystems, IBM Research, Unisys, HP,
Northrop Grumman Information Technology, British Telecom and EMC Corp.

The GridSim software has been used for modeling and simulating many
interesting systems and ideas. For example, IBM Research uses our DataGrid
package to simulate a grid meta-scheduler that tightly integrates
the compute and data transfer times of each job.
Another example is Universidad de Santiago de Compostela's extension of 
GridSim
to optimize execution of parallel applications on a Grid.
Our own uses include simulating economic Grid scheduler in a competitive
economy model, economic based cluster scheduler and cooperative Grid 
federation.

The contributors to the GridSim software (from early to new version) are:
* Rajkumar Buyya, GRIDS Lab @ The University of Melbourne.
* Manzur Murshed, GSCIT @ Monash University, Australia.
* Anthony Sulistio, GRIDS Lab @ The University of Melbourne.
