-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 Java Random class to select a resource and user entity
- to communicate to a regional GIS entity.
- 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 event that takes place at the GIS. Resources will
- register at 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: these files record when a resource suffers a failure
- and when it recovers from the failure. They also say 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, resource and VO. In this example we only have 1 VO.
-
- 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, all existing files will be overwritten.
