| 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 |
| 166 | the resources. In order to cleanup your slice : |
| 167 | <ol type="a"> |
| 168 | <li>Press the '''Delete''' button in the bottom of your canvas </li> |
| 169 | <li> Select "'''Delete at used managers'''" and '''confirm''' your selection. </li> |
| 170 | </ol> |
| 171 | Wait 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. |

180 | | 5. ''' Optional: Manually generate traffic ''' 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. |
181 | | * Follow [wiki:HowTo/LoginToNodes these instructions] and log in to the client node |
182 | | * When you have successfully logged in, run this command |
183 | | {{{ |
184 | | iperf -c server -P 2 |
185 | | }}} |
186 | | 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. |
187 | | * Scroll all the way down the server iperf log, and look at the logs for your transfers |
