Re: [Repast-interest] Multiple Simphony Runs

[Tatara, E. R. <ta...@an...>]

OK makes sense.  You can't run multiple simulations in the same JVM
since the RunEnvironment and RunState use static singletons.  I'll
consult with the other developers to see if there is a straigtforward
solution.

Hi Eric

 

Yes, I was attempting to run multiple instances in same JVM.

 

This was attempted by creating an instance (runner) of RepastRunner
extends AbstractRunner which is almost identical to TestRunner_2 class
discussed within this forum at the beginning January 2008, and November
2008. 

 

Initially I created many of these instances and tried performing
runner.step(); method on each separate instance (this is the part that
does not work )

I also had trouble implementing a play button, which I eventually
achieved by iteration of runner.step() method. Is there a more
sophisticated way of doing this ?

 

As I was unable to run multiple instances of Simphony in parallel within
same JVM (this would be nice ... ?) I decided to do this sequentially.
In this case I initialise only one instance, run it to the end and then
I reset, reinitialise, and run again for as many times as desired.
Finally  when all iterations (loops) are completed I end the entire
Simulation. This code can be seen below:

************************************************************************
************************************************ 

 

RepastRunner  runner = new RepastRunner();

 

while (running) { 

      if (!GeneticAlgorithmCoordinator.loopCompleted) {

            runner.step();

            tickCountFiled.setText(""+runner.getSimphonyTickCount());

      }

      else{

 
iterationField.setText((String.valueOf(GeneticAlgorithmCoordinator.loopC
ount+1)));

            if (GeneticAlgorithmCoordinator.simulationCompleted){

                  TextDisplay.getInstance().render();

                  new SummaryReportDisplay();

                  TextDisplay.getInstance().endIteration();

                  RunEnvironment.getInstance().endRun();

                  hide();

                  running = false;

            }

else{

      runner.stop();

                  runner.cleanUpRun();

                  try{

                        runner.load(file);

                  }catch (Exception e){

                  e.printStackTrace();

                  }

                  runner.runInitialize();

                  GeneticAlgorithmCoordinator.loopCompleted = false;

            }

      }

}

How are you running multiple instances?  If more than one in the same
JVM it might be problematic.

Hi

 

I am trying to run multiple instances of Simphony 1.2 with partial
success.

 

In my current example I try to run 5 instances and only the last one
seems to be working, and first four return tick count of -1. This might
indicate that there is no actions scheduled, however this is not the
case. 

 

I check for actions scheduled with following code:

                System.out.println("Checking Status at "+
GetTickCount());

       System.out.println("Actions: "+runner.getActionCount());

      System.out.println("Actions: "+runner.getModelActionCount());

      System.out.println(runner.getNextScheduledTime());

 

 

Here is my output for each Simphony instance:

 

1st:

Checking Status at -1.0

Actions: 7

Actions: 3

0.0

 

2nd:

Checking Status at -1.0

Actions: 7

Actions: 3

0.0

 

3rd:

Checking Status at -1.0

Actions: 7

Actions: 3

0.0

 

4th:

Checking Status at -1.0

Actions: 7

Actions: 3

0.0

 

5th: (working)

Checking Status at 0.0

Checking Status at 0.0

Checking Status at 0.0

Checking Status at 0.0

Actions: 12

Actions: 8

1.0

Checking Status at 1.0

Checking Status at 1.0

Checking Status at 1.0

Checking Status at 1.0

Checking Status at 1.0

Actions: 12

Actions: 8

1.083

 

 

I just can not figure this one out. Any suggestions are welcome.

 

Thanks

Bojan
