Re: [GridSim-users] simulation time

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

GridSim.clock() is in second (default unit).
It is not real time, instead it is a DISCRETE time.
The GridSim time jumps based on the arrival of new events,
e.g. simulation time = 0, 40, 100, 700, ...
As an anology, the time is similar to a train/bus timetable
on a particular station/stop.

For example, you run a GridSim experiment.
The clock time in your PC says Tuesday, 19 Aug 2008, 11:00
When simulation starts, GridSim.clock() = 0.
When GridSim.clock() shows 1000, it means
that at time 1000, a new event is happening
in the experiment.

It has nothing to do with the actual CPU time.
Your experiment might finish 2 minutes later at
Tuesday, 19 Aug 2008, 11:02.
