    1010In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on [wiki:cosmos_workflow the COSMOS work flow page] to get started.

     12=== Resources required ===
     132 host nodes and 2 USRP X310s are required for this experiment. USRP X310 devices in ORBIT grid are located in the massive MIMO mini-racks [https://www.orbit-lab.org/wiki/Hardware/bDomains/aGrid#Massive-MIMOmini-racks].

    1215=== Execution ===
    1316
    14 1. Determine the set of nodes that you're using. If you have a topology assigned, it will be entered in the form "system:topo:group-black" for example
     17==== Imaging the host nodes ====
    1518
    16 ==== Imaging the nodes ====
     19 Determine the set of nodes that you're using. If you have a topology assigned, it will be entered in the form "system:topo:group-red" for example.
     20* Load channel-sounder.ndz on a pair of nodes
     21{{{
     22prasanthi@console.grid:~$ omf load -i channel-sounder.ndz -t node19-1,node20-1
     23}}}
     24or if were assigned a topology,
     25{{{
     26prasanthi@console.grid:~$ omf load -i channel-sounder.ndz -t system:topo:group-red
     27}}}
    1728
    18 1. run {{{ onaptutorial-min.rb -g group-black }}}
    19 1. Test if the nodes are up, with {{{omf stat -t system:topo:group-black}}}
    20 1. If not in state POWERON, run {{{ omf tell -a on -t system:topo:group-black}}}
    21 1. Once they're up, they will respond to ping, e.g. {{{ping node13-8 }}}
    22 1. Download the cluster setup script {{{ wget -O create-cluster.sh }}}
    23 1. Run the cluster setup script on the prepared nodes {{{ ./create-cluster.sh -c node14-7 -w node13-8 }}}
     29* Turn the nodes on
     30{{{

     32}}}
     33or

    27 === Set Up ===
    28 Make a reservation on the [https://www.orbit-lab.org/schedule/ Orbit Scheduler] for using the grid.
    29 ==== Prepare Receive Node ====
    30 * Load channel_sounder_x310.ndz on an ORBIT node.
    31 {{{
    32 prasanthi@console.grid:~$ omf load -i channel_sounder_x310.ndz -t node1-19

    34 * Once imaging is done, turn the node on and log in
    35 {{{
    36 prasanthi@console.grid:~$ omf tell -a on -t node1-19
    37 prasanthi@console.grid:~$ ssh root@node1-19
