let ’s Get started to answer the “ How to install Cloudsim ? ”

First of all , navigate to the folder where you have unzip the Eclipse folder and open Eclipse.exe

Now within Eclipse window navigate the menu:File -> New -> Project, to open the new project wizard

A ‘New Project‘ wizard should open. There are a number of options displayed and you have to find & select the ‘Java Project‘ option, once done Click ‘ Next‘

Now a detailed new project window will open, here you will provide the project name and the path of the CloudSim project source code, which will be done as follows:

• Unselect the‘Use default location’ option and then click on ‘Browse’ to open the path where you have unzip the Cloudsim project and finally click Next to set project setting .

Make sure you navigate the path till you can see the bin , doc , example , etc folder in the navigation plane .

Once done finally, click ‘ Next’ to go to the next step i.e. setting up of project settings

Now open the ‘Libraries’ tab and if you do not find commons-math3-3.x.jar(here ‘x’ means the minor version release of the library which could be 2 or greater) in the list then simply click on ‘Add External Jar’ (commons-math3-3.x.jar will be included in the project from this step)

Once you is clicked have click on ‘Add External JAR’s‘ Open the path where you have unzipped the commons-math binaries and select ‘commons-math3-3.x.jar’ and click on Open.

Ensure the external jar that you opened in the previous step is displayed in the list and then click on ‘Finish’ (your system may take 2-3 minutes to configure the project)

Once the project is configured you can open ‘Project Explorer’ and start exploring the Cloudsim project. Also for the first time eclipse automatically start building the workspace for the newly configured Cloudsim project, which may take some time depending on the configuration of the computer system.

The final screen is appear will appear after Cloudsim is configure .

Now just to check you within the ‘ Project Explorer ‘ , you is navigate should navigate to the ‘ example ‘ folder , then expand the package ‘org.cloudbus.cloudsim.examples‘ and double click to open the ‘CloudsimExample1.java‘ .

Now navigate to the Eclipse menu ‘Run -> Run‘ or directly use a keyboard shortcut‘Ctrl + F11’ to execute the ‘CloudsimExample1.java‘ .

if it is successfully execute it is displaying should be display the following type to output in the console window of the Eclipse IDE .

If Yes then Congratulations!!

Now you have successfully set up/Installed the CloudSim Simulation Toolkit on your computer machine and you are ready to start with the experimentation for your further research work.

2. On the project properties window, from the list available on the left, select ‘Java Compiler’; this will display the compiler options.
3. Now, click on the ‘Enable Project Specific Settings’ checkbox, which further enables the options provided just below the checkbox.
4. Now, under the JDK compliance heading, change the ‘Compiler Compliance Level’ to the highest number available on the list.
5. Also , make sure “ use default compliance setting ” should be in the check state .
6. Now, click on the “Apply and Close” button. A popup alert will appear asking for confirmation to apply the settings. Click ‘Yes.’

Now you will notice that the rebuild process for the project will get started and confirm the error is resolved or not. You may check the error log window or run any example class available in org.cloudbus.cloudsim.examples namespace.
