     99            <li> Wait while your resources are being reserved. This will take several minutes so be patient. When your sliver is ready the background will be green. </li>

     122         <h3><u> Step 3: View Results: </u></h3>
     123         For this example experiment we used the install script facility to automatically install the necessary software and kick-off the experiment. In this very simple setup, we have installed and launched a
     124<a href="[" target="_blank"> web server </a> as well as an <a href="" target="_blank"> iperf server</a>, on the server host. On the client, we have started some processes to test both of these services. To view the results of this experiment:
     125            <table border="0">
     126              <tr>
     127                <td >
     128                 <ol type="a">
     129            <li> After the background of your slice turns green, press the (i) button that is on the server node icon.</li>
     130            <li> In the information tab that came up, press the <b>Visit</b> button. A new tab should come up that looks like the picture on the side. </li>
     131            <li> Click the <b>Web Server Statistics</b> link to look at statistics. Refresh the page a couple of times to see how the statistics change as the client requests documents.</li>
     132            <li> Click the <b>Logs from the iperf Server</b> link to see the statistics from the iperf transfers.</li>
     133           </ol>
     134                </td>
     136             </tr>
     137           </table>
     138              <h3><u> Optional Step 4: Manually generate traffic: </u></h3>
     139             While conducting experiments in GENI, you will often want to run commands directly on the nodes. In this optional step, you will log in to a node and issue commands directly to it.
     140              <ol type="a">
     141                 <li>  Follow <a href="" target="_blank"> these instructions</a> and log in to the client node </li>
     142                 <li> When you have successfully logged in, run this command:<br>
     144iperf -c server -P 2
     145</code> <br>
     146    This task shouldn't take more than 30 seconds. Change the number after the ` -P ` argument and watch how the performance is affected while you change the number of parallel TCP connections.
     147     </li>
     148   <li> Scroll all the way down the server iperf log, and look at the logs for your transfers </li>
     149   </ol>
     151          </td>
     152       </tr>
     158<table  border="0" cellpadding="0" cellspacing="0">
     159  <tr>
     160     <td valign="top" align="left">
     161        <img src=""  width="150" alt="Execute"></a>
     162      </td>
     163       <td>
     164              <h3><u> Step 5: Cleanup experiment: </u></h3>
     165           After you are done with your experiment, you should always release your resources so that other experimenters can use
     166the resources. In order to cleanup your slice :
     167              <ol type="a">
     168                 <li>Press the <b>Delete</b> button in the bottom of your canvas </li>
     169                 <li> Select <b>Delete at used managers</b> and <b>confirm</b> your selection. </li>
     170              </ol>
     171Wait and after a few moments all the resources will have been released and you will have an empty canvas again. Notice that your slice is still there. There is no way to delete a slice, it will be removed automatically after its expiration date, but remember that a slice is just an empty container so it doesn't take up any resources.

     180Congratulations! You have finished your first GENI Experiment. Now that you are more familiar with GENI concepts you can:
     181  * continue with more [wiki:GENIExperimenter/ExampleExperiments advanced tutorials]
     182  * learn more about how to use Flack by following the [ Flack Tutorial]
     183  * start with your own experiment. This tutorial showed you the basic steps for running an experiment. Use Flack to create your own topology, take a look at the [wiki:HowTo/WriteInstallScript instructions about how to write your own install scripts] to automate your expriment.
