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. 39 40 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: 40 41 {{{ 41 user@console.outdoor:~$ omf stat42 user@console.sb7:~$ omf stat 42 43 43 INFO NodeHandler: OMF Experiment Controller 5.4 (git c005675) 44 INFO NodeHandler: Slice ID: default_slice (default) 45 INFO NodeHandler: Experiment ID: default_slice-2013-01-16t14.42.48-05.00 46 INFO NodeHandler: Message authentication is disabled 47 INFO Experiment: load system:exp:stdlib 48 INFO property.resetDelay: resetDelay = 230 (Fixnum) 49 INFO property.resetTries: resetTries = 1 (Fixnum) 50 INFO Experiment: load system:exp:eventlib 51 INFO Experiment: load system:exp:stat 52 INFO Topology: Loading topology ''. 53 INFO property.nodes: nodes = "system:topo:all" (String) 54 INFO property.summary: summary = false (FalseClass) 55 INFO Topology: Loading topology 'system:topo:all'. 56 Talking to the CMC service, please wait 57 ----------------------------------------------- 58 Domain: outdoor.orbit-lab.org 59 Node: node1-1.outdoor.orbit-lab.org State: POWEROFF 60 Node: node1-10.outdoor.orbit-lab.org State: POWEROFF 61 Node: node1-2.outdoor.orbit-lab.org State: POWEROFF 62 Node: node1-3.outdoor.orbit-lab.org State: POWEROFF 63 Node: node1-4.outdoor.orbit-lab.org State: POWEROFF 64 Node: node1-5.outdoor.orbit-lab.org State: POWEROFF 65 Node: node1-6.outdoor.orbit-lab.org State: POWEROFF 66 Node: node1-7.outdoor.orbit-lab.org State: POWEROFF 67 Node: node1-8.outdoor.orbit-lab.org State: POWEROFF 68 Node: node1-9.outdoor.orbit-lab.org State: POWEROFF 69 Node: node2-10.outdoor.orbit-lab.org State: POWEROFF 70 Node: node2-2.outdoor.orbit-lab.org State: POWEROFF 71 Node: node2-3.outdoor.orbit-lab.org State: NOT REGISTERED 72 Node: node3-1.outdoor.orbit-lab.org State: POWEROFF 73 Node: node3-2.outdoor.orbit-lab.org State: POWEROFF 74 Node: node3-3.outdoor.orbit-lab.org State: POWEROFF 75 Node: node3-4.outdoor.orbit-lab.org State: POWEROFF 76 Node: node3-5.outdoor.orbit-lab.org State: POWERON 77 Node: node3-7.outdoor.orbit-lab.org State: POWEROFF 78 Node: node3-8.outdoor.orbit-lab.org State: POWEROFF 79 Node: node4-1.outdoor.orbit-lab.org State: POWEROFF 80 Node: node4-10.outdoor.orbit-lab.org State: POWEROFF 81 Node: node4-11.outdoor.orbit-lab.org State: POWEROFF 82 ----------------------------------------------- 83 INFO EXPERIMENT_DONE: Event triggered.

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: 109 89 '''baseline.ndz'''.
