+This directory contains few examples regarding to
+resource failure functionalities.
+Here are the summary of what each example does:
+./ResFailureEx01 : shows a very basic example,
+ dealing with 1 user, 3 resources and 1 GIS entities.
+
+./ResFailureEx02 : shows a basic example,
+ dealing with 20 users, 6 resources and 1 GIS entities.
+
+./ResFailureEx03 : shows a more complex example,
+ dealing with 30 users, 15 resources and 3 GIS entities.
+ However, you can modify these parameters as you wish,
+ but keep in mind that the simulation might run longer
+ if you increase the numbers.
+
+NOTE: Detailed explanations are provided in the source file(s).

+
+Welcome to the example of how to use the computing resource failure functionality
+To compile the example source code:
+ In Unix/Linux: javac -classpath $GRIDSIM/jars/gridsim.jar:. ResFailureEx01.java
+ In Windows: javac -classpath %GRIDSIM%\jars\gridsim.jar;. ResFailureEx01.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:. ResFailureEx01 network_ex01.txt > file.txt
+
+In Windows:
+ java -classpath %GRIDSIM%\jars\gridsim.jar;. ResFailureEx01 network_ex01.txt > file.txt
+
+
+The above command means run the program and output the results into a file
+named "file.txt" rather than into screen or standard output.
+To prevent from overwriting an existing file,
+I renamed "file.txt" into "output.txt"
+
+NOTE: This example uses probabilistic distributions and random variables.
+ Hence, when running this example many times, the values will be different.
+
+
+When running the example file, it will produce the following files:
+
+ 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.
+ Not to important for our example.
+
+ Ex01_Regional_GIS -> contains one line describing each
+ registering/removing an event that takes place at the GIS. Resources
+ register in the begining of simulations, and after recovering from a
+ failure affecting all their machines. Resources will be removed when
+ they suffer a failure affecting all their machines.
+
+ Ex01_Res_0, Ex01_Res_1, Ex01_Res_2 -> records when the resource
+ suffers a failure and when it recovers from the failure. It also records
+ how many machines failed, and the time of the fail/recovery.
+
+ Ex01_User0 -> contains one line for each event regarding to the Gridlets.
+ These events are the sending/reception of a gridlet, and
+ each line include the status of the gridlet, time and resource.
+
+ Ex01_User0_Fin -> contains one line for each gridlet, showing the resource
+ it has been executed, its cost, CPU time and total latency.
+
+NOTE: When you run the program multiple times, the new statistics will be
+ appended at the end of a file.
