     20In this part of the tutorial we give a brief overview on the experiment workflow.
     21GIMI is providing experimenters with a set of tools that will aid them in allocating GENI
     22resources (currently this is limited to ExoGENI resources), executing experiments, and performing
     23measurements while these experiments are running. In addition, the GIMI tools will allow
     24experimenters to analyze and visualize measurement data. Finally, a federated set of iRODS
     25servers provides an archival service.[[BR]]
     26The figure below illustrate what we describe as the experiment workflow.
     27During the tutorial we will walk through the single steps of this workflow with the goal to
     28have experimenters apply this workflow to their own experiments.
     29
     30== Topology ==
     31
     32The image below illustrates the ExoGENI topology that we will create within the scope of this tutorial. The experiment described above will be
     33executed on the basis of this topology.
     34
     35In Section 1.Reserving Resources, we will go through the process of setting up and obtaining a slice that represents this topology.
     36
     37[[Image(GIMI_Experiment_Topo.2.png)]]
     38
     39The routing in this topology is set up as follows:

     97
     98Here you will need to select the ExoGENI racks assigned to you for the tutorial. This assignment is only done so that we can distribute VMs across different ExoGENI racks. Outside of this tutorial, you can use any of the following racks:[[BR]]
     99
     1001. FIU ExoGENI[[BR]]
     1012. GPO ExoGENI[[BR]]

     110=== 1.4 Query for resources ===
     111Click on your slice name at the top and click on Resource Status. Once you see a READY on your resources, your slice is ready for experiments. You can refresh the page until you see READY.

     120== 2. Configure iRODs ==
     121The iRODs or Integrated Rule-Oriented Datasystem is a directory structure used to archive all experiment related data such as scripts, manifest RSpecs, experiment results and so on.[[BR]]
     122Please click on this link to learn more [https://www.irods.org/index.php/IRODS:Data_Grids,_Digital_Libraries,_Persistent_Archives,_and_Real-time_Data_Systems iRODs]. iRODs has been downloaded and installed on your VMs. [[BR]]
     123Please configure your iRODsEnv as explained here:
     124
     125=== 2.1 Create iRODs account ===
     126Login to your GENI Portal account and Click on the Profile tab on the top right corner of the page.[[BR]]
     127At the bottom of the Profile page, click on the Create iRODs button[[BR]].
     128
     129[[Image(iRODscreate.png)]]
     130=== 2.2 Configuring iRODs Environment ===
     131
     132You will be redirected to another page with your iRODs Environment and also your temporary iRODs account password.[[BR]]
     133Copy and paste the contents of the iRODsEnv into ~/.irods/.irodsEnv[[BR]]
     134
     135
     136Do
     137{{{
     138$iinit
     139}}}
     140Enter your temporary password. You can now do
