[GridSim-users] Using Gridsim to simulate reliability of computational resources

[Eran C. W. <era...@gm...>]

Hi,

I'm a PhD student from Indiana University and trying to use gridsim to
simulate unreliable computational resources.

I'm trying to use gridsim such that it will represent two or more compute
resources (each having many nodes in it). But I should be able to assign a
reliability distribution, just like HyperExponential function that you have
already implemented. This is how I want it to work.

1. A user code will create a gridlet representing a job it has
2. gridlet is given to gridsim and it will either successfully run (simulate
it) or will create a failure (following the given reliability distribution
function).
3. user will be notified, either using the gridlet itself or some other
mean, whether the job was successful or failed.
4. this process from 1-3 to will continue for all the jobs in a queue. But I
want the user code to be notified about the status of each job (success or
fail).

Can you please point me to a code sample or provide me a code sample that
can do this? When I looked in to the code, the examples always show that you
have to invoke gridsim.simulate and it will run all the gridlets at once.
But I want to go in the order given above.

Thanks,
Eran Chinthaka Withana

Hi Eran,

I can't see any difference between what u want to do and the examples of 
resource failure, coming along with GridSim code. Are u sure they don't 
fit ur needs?

Regards,

Agustin

Hi Agustin,

Thanks for your reply (but it has gone to my spam list).

Anyway, the gridsim examples show to setup the environment and start the
simulation. Once I call start simulation, it will simulate the
workload/gridlets without stopping. What I want is a way to submit a
gridlet, get the result, submit another gridlet, get the result kind of
scenario. Can you please let me know the way to do that if I can do it?

Thanks,
Eran Chinthaka Withana

In this case, all u have to do is modify the processGridletReturn() 
function (as called in GridUserFailureEx01.java class) to do what u 
want. This function is called when a gridlet is received, and 
essentially it collects statistics about the just received gridlet. Now, 
u have to modify it to submit the next gridlet.

Besides, u also have to modify the body() function, because by now it 
submits a gridlet when a GRIDLET_SUBMIT event. Now, u remove this part 
and submit gridlets as I mentioned above.

Hope this helps.

Agustin

Hi Augustin,

This helps. I will try this approach.
