| | 5 | == 1. Goals == |
| | 6 | The objective of this tutorial is to introduce the GIMI tool set to experimenters who are interested in performing |
| | 7 | experiments on ExoGENI slices. |
| | 8 | We will introduce an experiment workflow which experimenters will most likely apply to perform measurements. |
| | 9 | |
| | 10 | After the tutorial, experimenters should be able to: |
| | 11 | * Create a slice on ExoGENI and run an experiment on top of this slice. |
| | 12 | * Orchestrate experiments with OMF: |
| | 13 | * Set up routing on top of topology |
| | 14 | * Verify that topology has been set up correctly |
| | 15 | * Execute an experiment that measures the impact of packet size on throughput by comparing udp output at the sender and udp input at the receiver. |
| | 16 | * Store and retrieve data to/from iRODS |
| | 17 | * Analyze/visualize measurement data with various tools |

| | 27 | == 3. Workflow == |
| | 28 | |
| | 29 | In this part of the tutorial we give a brief overview on the experiment workflow. |
| | 30 | GIMI is providing experimenters with a set of tools that will aid them in allocating GENI |
| | 31 | resources (currently this is limited to ExoGENI resources), executing experiments, and performing |
| | 32 | measurements while these experiments are running. In addition, the GIMI tools will allow |
| | 33 | experimenters to analyze and visualize measurement data. Finally, a federated set of iRODS |
| | 34 | servers provides an archival service.[[BR]] |
| | 35 | The figure below illustrate what we describe as the experiment workflow. |
| | 36 | During the tutorial we will walk through the single steps of this workflow with the goal to |
| | 37 | have experimenters apply this workflow to their own experiments. |

| | 70 | == 4.Topology == |
| | 71 | |
| | 72 | The image below illustrates the ExoGENI topology that we will create within the scope of this tutorial. The experiment described above will be |
| | 73 | executed on the basis of this topology. |
| | 74 | Note, that NodeC is running in a different physical location (BBN) than the other nodes (RENCI). |
| | 75 | In Section [[http://groups.geni.net/geni/wiki/GIMIv1.1Tutorial/Slice Obtain Slice]], we will go through the process of setting up and obtaining a slice that represents this topology. |
| | 76 | |
| | 77 | [[Image(topology.jpg)]] |
| | 78 | |
| | 79 | The routing in this topology is set up as follows: |
