Accessing your cluster via ssh

Added: 26 Jun 2012

Behind the accessible and functional web interface, CloudMan allows you to access your cluster from the command line as well. You can find the exact command needed to ssh (including the current IP) on the Admin interface:

ssh command on the Admin page

(Note that CloudMan images created after 2012 allow you to also log in using the same password as you use for accessing the CloudMan web interface; simply log in as ubuntu user).

To ssh to the instance, simply start the Terminal application (or Putty on Windows) and provide the command:

ssh command

Once logged in, the cluster behaves just like any other SGE-managed cluster: submit a job using qsub <job script>:

Submit a job via qsub

Check the status of a job or the queue, use qstat -f:

 Check queue status

For ubuntu user, CloudMan stores all of the persistent data in /export/data. This directory is also shared over NFS with worker nodes and should thus be used for submitting jobs from and having the output stored there.

And there you go - a scaleable and functional compute cluster ready for anything you throw at it.
