    38 When you have successfully logged in, you can start an experiment using the [wiki:/Software/bAM#AggregateManagers Orbit Management Framework (OMF)]. First time users are '''highly''' encouraged to reserve time on a sandbox instead of the main grid, and start with the built-in [wiki:/Tutorials/HelloWorld Hello World] experiment.

    3940 1. Before we begin using the nodes, it's a good idea to check their status first. This is done with the omf stat command. This will typically produce a result like:

    8969    Individual nodes are identified by their fully qualified domain name (FQDN). This establishes their "coordinates" and the "domain" to which they belong. Nodes in
     
    9474    || POWEROFF       || Node is Available for use but turned off ||
    9575    || POWERON        || Node is Available and is on ||
    96     || NOT REGISTERED || Node is not Available for use ||[[BR]]
     76    || NOT REGISTERED || Node is not Available for use ||

    9878 3. It is recommended that the node be in the POWEROFF state prior to any experiment process. If the node is in the POWERON state you can use the omf tell command
     
    10282    }}}
    10383    The ''TOPOLOGY'' can take on many forms, the simplest being a comma separated list of FQDN's. There are special predefined topologies like: all, system:topo:circle, ...

     84    For more details see [wiki:/Software/cOMF OMF documentation]
    10585    If the node is in the NOT REGISTERED state, you may need to wait for it to recover the POWEROFF state (it some times requires a few moments for the services to sync up). If
    10686    the node never comes out of the NODE NOT AVAILABLE state please contact an administrator.
     
    10888 4. Prior to the experiment, users need to install an image on the hard disks of the nodes. If you have not created a custom image use the default starting image:
    10989    '''baseline.ndz'''. This image is built on top of '''Ubuntu 12.04''', and is pre-configured with the proper modules and start up scripts to take advantage of the rest of
    110     the Orbit services / hardware.  Loading an image is done with the [wiki:/Software/bAM#AggregateManagers omf load command].
     90    the Orbit services / hardware.  Loading an image is done with the [wiki:/Software/cOMF#load omf load command].
    11191    {{{
    11292    username@console.domain:~$ omf load -t TOPOLOGY -i IMAGENAME
     
    177157    Give the nodes a couple of minutes to turn on / boot, then check their status with omf stat.
