Re: [GridSim-users] how to learn about gridsim??

[Marcos D. de A. <mar...@gm...>]

Hi,

GridSim is a framework that provides you with a Java API that you can 
used to create your simulations. Thus, I believe that the best way to 
learn it is to check how you can use this API.

I would recommend you to install GridSim in your favourite IDE (e.g. 
Eclipse) and go through the examples  included in examples/gridsim. By 
starting with example01, going until example10 and reading the comments 
inserted in the classes, you will have a good idea of how GridSim works. 
If you have trouble understanding GridSim, you can send a message to 
this list.

Regards,

Marcos

[GridSim-users] how to learn about gridsim??

[Mayuri M. <may...@gm...>]

Hi,
Mine is very basic question. Recently i came to know that i can use gridsim
for implementing and evaluating the performance of different load balancing
algorithms of distributed systems.

But i donot know from where to start learning of gridsim.
I want to learn it from scratch and at present i donot know anything about
it except its name. I have already downloaded it but donot know how to work
with it.

pls help me soon.

Re: [GridSim-users] resourceID

[Marcos D. de A. <mar...@gm...>]

Dear Raksha Sharma,

If you use any of the methods gridletSubmit() of GridSim class, you must 
provide the ID of the resource to which you are submitting the Gridlet. 
In this case, that is the resource ID for the Gridlet.

Additionally, you can set the resource ID for a given Gridlet using the 
the method setResourceParameter(int resourceID, double cost) of Gridlet 
class.

Kind regards,

Marcos

[GridSim-users] Doubt with ResFailureEx03

[Vinicius P. <vin...@gm...>]

Hi people,

I'm running the ResFailure.example03 and I have some doubts.
I run with two failureTimePattern configuration: one with
HyperExponential(25, 100, 4) and other with HyperExponential(250, 100,
4);

My expectation was that using 250 as avarega instead of 25 would lead
to a smalllest CPU time since the interval between failures increased.
But the opposite occurred.
I don't undestood this behaviour. Can someone give me a help on this?

Best regards,

Vinicius Pinheiro

with HyperExponential(25, 100, 4);

[GridSim-users] resourceID

[raksha s. <rak...@gm...>]

hi to all,
i want to know ...
how i aa the ID of resource(to which gridlet is to be assigned)in to a
linked list.
please reply.

Re: [GridSim-users] grid sim simulation.plz help me sir its very urgent.

[Marcos D. de A. <mar...@gm...>]

Dear Vishnu Soni,

I believe your question has already been answered. Please find below
the text of the e-mail that I have sent to you. The code excerpt may
help you implement the methods you require to submit a group of
Gridlets to a GridResource at once.

Regards,

Marcos

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

I am not testing the code below, but it should work more or less as
described in this email. In the entity that submits the jobs you
implement a method that packs the Gridlets in a list and schedules an
event to be received by the GridResource. The method should contain
more or less the following:

// Creates the list
LinkedList<Gridlet> jobList = new LinkedList<Gridlet>();

// and adds the Gridlets to it
jobList.add( ... );

// Create the event tag PACK_OF_GRIDLETS somewhere
send(super.output, delay, PACK_OF_GRIDLETS, new IO_data(jobList,
jobList.size() * size_of_one_job, resourceID, netServiceLevel);

Then extend GridResource class and implement the method
processOtherEvent(Sim_event ev), which will be more or less as
follows:

protected void processOtherEvent(Sim_event ev) {
       if(ev.get_tag() ==  PACK_OF_GRIDLETS) {
    // get the list of Gridlets
    LinkedList<Gridlet> jobList = (LinkedList<Gridlet>)ev.get_data();
        // for each gridlet, makes a submission to the resource itself
    for (Gridlet gl : jobList) {
         processGridletSubmit(gl, false);
    }
 } else {
     super.processOtherEvent(ev);
 }
}

And the processGridletSubmit() should look like:

private void processGridletSubmit(Gridlet gl, boolean ack) {
       try {

          // checks whether this Gridlet has finished or not
          if (gl.isFinished()) {
              String name = GridSim.getEntityName( gl.getUserID() );
              System.out.println(super.get_name() + ": Warning - Gridlet #" +
                      gl.getGridletID() + " owned by " + name +
                      " is already completed/finished.");
              System.out.println("Therefore, it is not being executed again");
              System.out.println();

              // NOTE: If a Gridlet has finished, then it won't be processed.
              // So, if ack is required, this method sends back a result.
              // If ack is not required, this method don't send back a result.
              // Hence, this might cause GridSim to be hanged since waiting
              // for this Gridlet back.
              if (ack) {
                  int[] array = new int[2];
                  array[0] = gl.getGridletID();
                  array[1] = GridSimTags.FALSE;

                  // unique tag = operation tag
                  int tag = GridSimTags.GRIDLET_SUBMIT_ACK;
                  super.send(super.output, GridSimTags.SCHEDULE_NOW, tag,
                          new IO_data(array, SIZE, gl.getUserID()) );
              }

              super.send(super.output, 0, GridSimTags.GRIDLET_RETURN,
                  new IO_data(gl,gl.getGridletOutputSize(),gl.getUserID()) );

              return;
          }

          // process this Gridlet to this GridResource
          gl.setResourceParameter(super.get_id(), resource_.getCostPerSec());
          policy_.gridletSubmit(gl, ack);
      } catch (ClassCastException c) {
          System.out.println(super.get_name() + ".processGridletSubmit(): " +
                  "ClassCastException error.");
          System.out.println( c.getMessage() );
      } catch (Exception e) {
          System.out.println(super.get_name() + ".processGridletSubmit(): " +
                  "Exception error.");
          System.out.println( e.getMessage() );
      }
}


Well, the code above may not work exactly like I described here, but
you can have an idea on how to do it.

Marcos

Re: [GridSim-users] grid simulation

[Marcos D. de A. <mar...@gm...>]

Hi, you can obtain the processing time of a Gridlet, here called gl, on 
the last resource where it was executed by subtracting the start time 
from the finish time. That is:

double procTime = gl.getFinishTime() - gl.getExecStartTime();

If you need to record other type of data, you might want to extend one 
of the allocation policies and the Gridlet class to store the 
information you need. If you are interested in an event in specific, you 
can obtain the simulation time at which it happened:

double timeEvent = GridSim.clock();

Cheers,

Marcos

Re: [GridSim-users] reg job replication

[Marcos D. de A. <mar...@gm...>]

After a Gridlet is returned by a GridResource, you can invoke methods 
from the Gridlet class such as getWallClockTime() to get the amount of 
time that the Gridlet stayed in the last resource. Also, you can used 
other methods like getExecStartTime(),  getSubmissionTime() and 
getFinishTime() to calculate the time to which you refer.

Sorry, but I did not understand what you intended to do by reading the 
previous e-mail.

Marcos

Re: [GridSim-users] gridsim simulation

[I-Sha F. <mas...@gm...>]

Hi,

 Regarding Vishnu question and Marcos answer, I'm interesting to know more
on those technique.

As , Marcos said, we need to extent the GridResource class, meaning we need
to extend some
feature in gridletSubmit? Can you briefly give some idea on how to
adjust this event environment?

Thank you.

Re: [GridSim-users] Query

[Marcos D. de A. <ass...@ac...>]

Dear Mayuri Mehta,

yes, you can use GridSim for that purpose. You need to model the
environment you consider and implement the load balancing mechanism.
GridSim will provide you with a framework to simulate and evaluate
your load balancing techniques.

Marcos

Re: [GridSim-users] gridsim simulation

[Marcos D. de A. <ass...@ac...>]

Dear Vishnu Kant Soni,

In order to send Gridlets to resources, you can utilise the
gridletSubmit() methods implemented in GridSim class. However, they
dispatch one job per method call. If you want to dispatch a set of
gridlets, you should call that method several times, one per job in
the set. Alternatively, you can implement the feature to send a list
of jobs to a Grid resource (i.e. schedule a new simulation event type
for it). But in that case you need to extend the GridResource class to
ensure that it can handle an event whose data contains a list of jobs.

Re: [GridSim-users] reg job replication

[Marcos D. de A. <ass...@ac...>]

Dear Charrlie,

I'm not quite sure if I understood what you intend to do. What do you
mean by job effective time?

Regards,

Marcos

Re: [GridSim-users] running the parallel examples on eclipse

[Marcos D. de A. <mar...@gm...>]

To run the examples in the parallel package, you need to provide a 
workload trace file that contains the information about the jobs to be 
created during the simulation. Two sample files are provided in the 
directory examples/parallel. If you run the examples using eclipse, you 
need to customise the class you want to run and provide the path to one 
of this files as an argument when you run the class.

Marcos

hi,
      how i set the different baud_rate for different resources.and
how i grouped the jobs according to job MI.means i m comparing the job
MI to resource MIPS and assign the jobs in a groups ,but how i send
the goups jobs to the resource.plz explain me sir and give me some
code for that.

Re: [GridSim-users] Gridsim query regarding the input trace files

[Marcos D. de A. <mar...@gm...>]

Hi Srishti,

the input files used by those examples are included in 
examples/parallel. Their names are sdsc_blue_01.txt and 
sdsc_blue_02.txt, and they follow the standard workload format (SWF). 
More information about this format along with other logs can be obtained 
from:  http://www.cs.huji.ac.il/labs/parallel/workload/

Cheers,

Marcos

[GridSim-users] Gridsim query regarding the input trace files

[Srishti S. <sri...@gm...>]

Hi,

I am trying to use grid sim to simulate scheduling algorithms for load
balancing. For which I went through the examples for scheduling tasks with
backfiling algorithm. These examples use an input file which is either a
trace file or a workload file. Could anyone please help m,e understand the
syntax of these files and how can they be created to be used as input files
for the simulation of the scheduling algorithms.
Would really appreciate even the smallest details as help.

Thanks,
Srishti

[GridSim-users] Grid Scheduling

[miren k. <mir...@ya...>]

hi,
My project is on Grid Computing and I am working on Grid Task Scheduling Algorithm. My algorithm is based on HEFT Task Scheduling algorithm.
My work is to compare my proposed algorithm with the existing HEFT algorithm. I have done this on paper and I got better results then HEFT.
Now I want to simulate my algorithm using GridSim Simulator.
Gridsim uses TimeShared Algorithm that is similar to RR algorithm and SpaceShared class is an allocation policy for GridResource that behaves exactly like First Come First Serve (FCFS).
There is a project named ALEA that is developed upon gridsim which can be downloaded from (http://www.fi.muni.cz/~xklusac/alea/Alea2-1-distribution.zip.)
Alea already has the following algorithms implemented in it:
FCFS, EDF, Easy Backfilling, PSPro.
Now my task is to integrate the HEFT and modified HEFT algorithm in the Gridsim or Alea project.

The task is to convert the algorithm into java code and integrate it as a method in scheduler.java file which is present in the alea project as far as I know.


and for any other queries contact me on following email:

mir...@ya...


your help will be most appreciated...

Thanks & Regards...

Miren
