Re: [GridSim-users] Getting the amount of computation executed so far

[Anthony S. <an...@cs...>]

Hello,

The resource scheduler i.e. SpaceShared or TimeShared
will update the gridlet length or call
Gridlet#setGridletFinishedSoFar() method,
according the following conditions:
- the gridlet is finished executing
- the gridlet is cancelled
- the gridlet is migrated to another resource

The reason is GridSim is a discrete-event simulation, hence, the 
simulation time is not continuous, e.g. time = 1, 2, 3, 4, ...
Instead, the time jumps based on the arrival of new events,
e.g. simulation time = 0, 40, 100, 700, ...


Thus, the best way to check the status of a gridlet is by using
the GridSim#gridletStatus() method.
This method returns the current Gridlet status or -1 if not found.
The various Gridlet status can be found in Gridlet class.
Note that you should only call this method at a certain interval,
not in a loop, since it will slow down the simulation.
In addition, the gridlet length will still be zero, until
one of the 3 conditions is satisfied.
