Log Message:
-----------
This version contains many changes and bug fixes:
+ Some classes have been moved to gridsim.turbo package.
+ The ParallelSpaceShared policy has been changed substantially and some bugs have been fixed. For example, the policy was not compressing the schedule properly when cancelling a gridlet. This could also lead to finding the wrong anchor for a job when the completion of a job matched the completion of another job and there was a big job starting at this completion time.
+ Some advance reservation features have been provided, but they are still being tested.
+ Improvements in the graphical user interface have been made.
+ Some changes in SimJava classes have been made to remove the animation and log capabilities that are not used by GridSim.

-Welcome to the 10th Example of how to use GridSim package.
-To compile the example source code:
- In Unix/Linux: javac -classpath $GRIDSIM/jars/gridsim.jar:. Example10.java
- In Windows: javac -classpath %GRIDSIM%\jars\gridsim.jar;. Example10.java
-
-where $GRIDSIM or %GRIDSIM% is the location of the gridsimtoolkit package.
-
-
-To run the class file:
- In Unix/Linux:
- java -classpath $GRIDSIM/jars/gridsim.jar:. Example10
-
- In Windows:
- java -classpath %GRIDSIM%\jars\gridsim.jar;. Example10
-
-
-NOTE: This example uses Java Random class to select a resource entity to
- process a Gridlet. Hence, when running this example many times,
- the values are different.
-
-
-When running the example file, it will produce the following files:
-
- tracefile -> created by SimJava 1.2, now being replaced by sim_trace
- NOTE: GridSim 2.1 uses SimJava 1.2 package
- GridSim 2.2 onwards use SimJava2 package
-
- sim_trace -> created by the SimJava2 package (lower-level) to trace every
- events (performed by SimJava and GridSim) during the simulation.
- We don't need to worry about this file. Not to important for our
- example.
-
- sim_report -> created by the SimJava2 package (lower-level) of GridSim.
- This is a simulation report that contains general information about
- running this experiment. We don't need to worry about this file.
