[wiki:WikiStart Orbit] > GettingStarted = How to get started = First, you will need an ORBIT account. Please check the [wiki:Documents/About/UsagePolicy usage policy] if you are eligible. Typically, in order to get an account,one would have to [http://www.orbit-lab.org/userManagement/register register for an account] and get it approved by the PI in charge of the project/institution they wish to be part off. If particular institution is not available, the appropriate PI can [http://www.orbit-lab.org/userManagement/orgReg register] for an institutional account. A typical experiment requires the following five steps: 1. Create reservation: before you can access the testebed,you need to [http://www.orbit-lab.org/scheduler/ make a reservation] and get it approved by the [wiki:Documentation/Scheduler reservation service]. First time users are '''highly''' encouraged to reserve time on a sandbox instead of the main grid, and start with this built-in [wiki:/Tutorials/HelloWorld Hello World] experiment. For the rest of this tutorial we will assume that user reserved sb1. 2. After you receive the confirmation email, you can access the reserved domain by ssh to the corresponding domain console. [[CollapsibleStart(Login into reserved domain)]][[Include(Documentation/Short/Login)]][[CollapsibleEnd]] {{{ ssh username@sb1.orbit-lab.org }}} 3. Load the baseline.ndz image on the nodes in reserved domain. [[CollapsibleStart(Load an image on the nodes)]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]] Prior to executing the "Hello World" experiment, users need to install an image on the hard disks of the nodes. For this tutorial we will use '''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 the Orbit [wiki:/Software software] / [wiki:/Hardware hardware]. {{{ username@sb1.orbit-lab.org:~$ omf tell -a offh -t all ... username@sb1.orbit-lab.org:~$ omf load -i baseline.ndz -t all ... }}} The imageing process will turn the nodes back off after completing imageing. At this point the nodes disks are imaged with the ''basline'' image and need to be turned back on before proceeding: {{{ username@console.sb1:~$ omf tell -a on -t all }}} Give the nodes a couple of minutes to turn on / boot, then check their status with omf stat 4. Run the experiment: execute your "Hello World" experiment.[[CollapsibleStart(Execute experiment with omf)]][[Include(Software/cOMF/aExec)]][[CollapsibleEnd]] 5.
