'''[wiki:GEC16Agenda/WiMAX-Tutorial/Streamload/06 Previous]''' == Run the experiment == Ready to run the experiment? First turn the nodes on, since they'll still be off after being imaged: {{{ omf tell -a on -t node1-5.sb4.orbit-lab.org,node1-6.sb4.orbit-lab.org,node1-9.sb4.orbit-lab.org }}} [[br]] Then run: {{{ omf exec wmxtutor-streamload.rb }}} [[br]] Make a note of your experiment ID, which is printed on the console like this: {{{ INFO NodeHandler: Experiment ID: default_slice-2013-07-17t19.19.57.782-04.00 }}} [[br]] Once the experiment has concluded, note its Experiment ID push the results to a "streamload" directory in iRODS using this ID: {{{ iarchive -e expID -c streamload }}} (replace '''expID''' with your actual Experiment ID as printed on the console) [[br]] To view your experiment results, visit the iRODS web browser at [http://witestlab.poly.edu/irods/web]. Use: * '''Host''': emmy9.casa.umass.edu * '''Port''': 1247 * '''Zone''': geniRenci [[br]] Click on the '''expID'''.sq3 file and click 'Plot' to create simple plots of measurements stored by OML. Try creating the following plots: * Plot table 'streamload_play' with 'chunk' on the x-axis, 'layer' on the y-axis, and group by 'oml_sender_id'. This will show you the number of layers downloaded for each of the 40 video segments, for each client. * Plot table 'wmxstat_status' with 'oml_seq' on the x-axis, 'cinr' on the y-axis, and group by 'oml_sender_id'. This will show you the WiMAX link quality as measured at each node for the duration of the experiment. The results may look something like this: || [[Image(wmxstat-sl-static.png, 350)]][[BR]] WiMAX link status||[[Image(play-sl-static.png,350)]][[BR]]Layers played, per segment || You can also download this file and explore the data using an SQLite browser such as [https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/ this Firefox plugin].
