Access to the green II supercomputer is available through Secure Shell (SSH) to g2.hpc.swin.edu.au for all users. i.e:
The g2 head-node should only be used as an entry point to the supercomputer, for submitting jobs to the queue nodes, and transferring files (single process only). Compute jobs found to be running directly on the head-node will be removed without notice.
We have a set of interactive nodes (gstar001, gstar002, sstar001, sstar002, and sstar003) that can be used to run short jobs directly, compile code, or test your application. These nodes can be accessed from the g2 head node via ssh too. i.e:
Please don’t use these nodes to run long jobs or jobs with big computational requirements. Running such jobs in interactive mode can be done by requesting interactive nodes from the queue. Jobs running on interactive nodes can use up to 80% of the nodes total memory with a maximum of 4 GB of swap.
A terminal is required to access Green II via Secure Shell (SSH) and issue command line instructions.
|Mac||Available by default via Applications > Utilities > Terminal|
|Linux||Available by default|
|Windows||The recommended software is Putty|
In order to transfer files from and to Green II a ssh-based file transfer utility is required. There are a variety of Options that you can use.
|Mac||“scp” (secure copy) command can be used via the terminal or use Cyberduck as a GUI alternative|
|Linux||“scp” (secure copy) command can be used via the terminal|
|Windows||The recommended software is WinSCP|
X11 Windows Forwarding
If you prefer to use the graphical screen of your application rather than a terminal, the ability to forward a graphical screen from the application back to your home computer is available via X11 Windows Forwarding.
With Linux and MacOS this can be done by login from the command line Secure Shell with the -X option (for X forwarding):
ssh -X [username]@g2.hpc.swin.edu.au
For MacOS you will first need to install XQuartz.
For Windows you will need to install an X11 Server implementation. The following options can be used:
You will need also enable X11 forward from Putty, before connecting, This can be done through connection > SSH > X11 by selecting “Enable X11 Forwarding”.
