+Software Requirements : Java version 1.4.2 or newer
+---------------------
+GridSim has been tested and ran on Sun's Java version 1.4.2 or newer.
+Older versions of Java are not compatible.
+If you have non-Sun Java version, such as gcj or J++, they may not be compatible.
+You also need to install Ant to compile GridSim (explained in more details later).
+
+
Installation and Running GridSim Toolkit
----------------------------------------
+There is no special program to install GridSim. You just need to
+unzip the GridSim file to install.
+If you want to remove GridSim, then remove the whole $GRIDSIM directory.
NOTE: You do not need to compile GridSim source code. The JAR file is
provided to compile and to run GridSim applications.

+Q: I came across three variables: peak load, off-peak load and holiday load.
+ I understand from the study I have done that these variables represent

+ you could help me out so I can progress further with my work.
+A: These load factors are influencing the total execution time
+ of a job in a given resource.
+ If you set these loads to zero, means this resource is idle / free.
+ If you want to write a resource scheduler, like SpaceShared or TimeShared
+ then these load factors are important.

+Q: for the Gridlet class, what are the units of file size, length, and output?
+
+A: the unit of file size and output is in byte.
+ For the Gridlet length, the unit is in MI (Millions Instructions).
+ A CPU clock is measured in MIPS (Millions Instructions Per Second) as
+ suggested by SPEC.
+
+---------------------------------------------------------
+Q: In the previous releases of GridSim you had to use
+GridSim class to send messages to other entities. The provided "send" methods
+included a parameter to indicate the sender of the request. It is no clear how
+to indicate this with the "send" methods provided by the GridSimCore class. The
+lack of ID information in the event raises an exception in the GridResource
+class. Reading the source code of the GridResource class I've realized that the
+way to send the ID of the sender could be the following:
+
+super.send(resourceId, GridSimTags.SCHEDULE_NOW,
+GridSimTags.RESOURCE_CHARACTERISTICS, new Integer(this.get_id()));
+
+This solves the first problem but generates a new exception in other class:

+The new version of GridSim adds a new functionality that supports
+resource failures and failure detection of Grid resources. This work was done
+in collaboration with Agustin Caminero, a Phd student from
+Universidad de Castilla La Mancha (UCLM), Spain.
All components developed as part of the GridSim Toolkit are released as

+SourceForge (http://sourceforge.net/projects/gridsim) for hosting
+our future releases and developments. This allows us to share and
+and to collaborate further on new functionalities.
+Therefore, contributions to the GridSim Toolkit are greatly appreciated.
The early version of our GridSim toolkit has been used/dowloaded by several
academic and commercial organizations around the world including:
-California Institute of Technology, Argonne National Labs,
-University of Illinois, Manchester University, CERN, Carleton University,

+This directory contains few examples regarding to

+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.

+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,

+ if you increase the numbers.

+
+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:. ResFailureEx02 network_ex02.txt > file.txt
+
+In Windows:
+ java -classpath %GRIDSIM%\jars\gridsim.jar;. ResFailureEx02 network_ex02.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.
+
+ Ex02_Regional_GIS_0, ..., Ex02_Regional_GIS_2 -> 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.
+
+ Ex02_Res_0, ... , Ex01_Res_8 -> 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.
+
+ Ex02_User_0 -> 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.
+ Then, when a simulation ends, this file shows the resource
+ a Gridlet 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.

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.
+ 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.

+
+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:. ResFailureEx02 network_ex02.txt > file.txt
+
+In Windows:
+ java -classpath %GRIDSIM%\jars\gridsim.jar;. ResFailureEx02 network_ex02.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.
+
+ Ex02_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.
+
+ Ex02_Res_0, ... , Ex01_Res_5 -> 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.
+
+ Ex02_User_0 -> 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.
+ Then, when a simulation ends, this file shows the resource
+ a Gridlet 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.

-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.

+
+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.
