[GridSim-users] gridsim simulation

[vishnu s. <vis...@gm...>]

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.
                 thanks,

                                    vishnu kant soni

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.

Regards,

Marcos

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] gridsim simulation

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

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
