[GridSim-users] many simulations with only a Java process

[<coa...@ti...>]

Hello,
I am an Italian student of the Faculty of "Ingegneria 
Informatica" of University of Catane, using Gridsim for my thesis.
I'd 
like to know if there is a way to do many simulations with only one 
java process.

For example: I want to check how my scheduling algorithm 
reacts to jobs of different length:short jobs and long jobs.
To do this 
I want to make a simulation (SIMULATION_1) with a set of short gridlets 
and another simulation (SIMULATION_2) with a set of long gridlets.
I'd 
like to start these two simulations with only one Java process.

I've 
tried a possible solution: I've set up two thread one for simulation_1 
and one for simulation_2. I've put GridSim.init(...) and GridSim.
startGridSimulation() lines in the run() method of each of the two 
Threads.
Thread_1 works -> OK
Thread_2 doesn't work.
In fact, when 
Thread_2 runs, all the Grid_sim entities doesn't execute their body() 
method.

I am sure that Thread_2 starts only after that Thread_1 has 
Finished, because I've used the Thread.join() method and, in fact, on 
the screen appears:

"
...
Simulation completed.
Initializing GridSim 
package
...
"

where "Simulation completed" refers to the simulation_1 
and "Initializing GridSim package" refers to simulation_2.

What 
happens?

What else can I do?

Is there anybody who can help me, 
please?
Thanks.
