How to get started

First, you will need an ORBIT account. Please check the usage policy? if you are eligible. Typically, in order to get an account,one would have to 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 register for an institutional account.

First time users are highly encouraged to reserve time on a sandbox instead of the main grid, and start with the built-in Hello World? experiment (including ability to access all 400 nodes in the grid).

Login into reserved domain

During your approved time slot, you will be able to ssh into the console of the respective domain. A console is a dedicated machine that allows access to all resources in that domain.

For example, to access the sandbox1:

Loading an Image

When you have successfully logged in, you can start an experiment using the Orbit Management Framework (OMF).

  1. 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.domain:~$ omf tell -a on -t all
    Give the nodes a couple of minutes to turn on / boot, then check their status with omf stat.

Where to go from here

If you are still unsure what Orbit is, please read the FAQ and the Tutorial?, otherwise go ahead and register.
