in gridsim how can i draw a graph of my results?can it be done by visual
modeler?is there any option in it?or should i have to import it from any
others like MS Excel?

Dear All:

I am currently using GridSim for a project, but I have encountered a
problem:
could GridSim simulation run several times in a single class or
function, because I want to take the average performance of the simulation?

As I wanna my program be like:
class gridsim(){
	main(){
		1st Simulation
		2nd Simulation
		...
	      }		

Is there any thread or something that I will need to destroy after 
calling the simulation? As the 2nd simulation does not work.

Does anyone has met the same problem or knows how to do? I would be
appreciate if you could help me on this.

Best,
Guanzhou

Hi,

What I do is the following:

1- Once I've implemented my stuff, I create a .jar file. The tool u use 
to program (e.g. eclipse, jbuilder,...) will have details on this point. 
The .jar file can be executed by java -jar file.jar [parameters]

2- Then, create a linux script or a windows batch file containing your 
experiments. For instance, it could look like this:

    java -jar mycode.jar para1 para2 para3
    java -jar mycode.jar para1 para2 para3
    java -jar mycode.jar para1 para2 para3
    java -jar mycode.jar para1 para2 para3

    Pay attention that each experiment should write results in files 
with different names, otherwise u would overwrite the results of the 
previous experiments.

3- Once ur experiments are over, just implement a program that 
calculates averages, ... whatever statistical measures u need. Then, u 
can plot them using gnuplot.

Cheers,

Agustin

It fails because some singletons are used and AFAIK there is no clean way to
reset the variables. I also use an external script to execute the whole thing
several times (as some people has advised you).

But for instance Alea (a package based on GridSim for testing scheduling
algorithms) uses a modified simjava package that implements a method that resets
these inner variables.

Furthermore, if you are using another GIS (such as DataGIS), you will also need
to reset it, and the method setGIS is not enough, you need to "unsetGIS" first.
But this method is not implemented, so I coded it in GridSim class:

public static boolean unsetGIS()
{
    gis_ = null;
    return true;
}

That's all

Hi,
For me, I will write the results into a plain file and generate the  
expected graph using third party toolkit, e.g. GNUPlot, since it seems  
to be out of the range of GridSim. Any other suggestions?

Regards
ye
