Getting Started

Training

If you are having trouble getting started, don’t be discouraged! We acknowledge Artemis has a learning curve. However, we run regular training sessions to help help you learn to use Artemis.

The best way to get started with Artemis is to attend an Introduction to Unix training course, then attend an Introduction to Artemis HPC training course. Over two days, you will learn how to use the Linux command line and submit jobs to Artemis. No prior knowledge is necessary to attend the Introduction to Unix course, and the only assumed knowledge for the Introduction to Artemis course is what you learned in the Introduction to Unix course. Both courses are offered at no cost to University researchers.

The vast majority of Artemis users begin with little to no previous Linux/Unix computing background, so don’t be afraid to attend a training course because you believe you aren’t good enough with computers!

Contact sih.training@sydney.edu.au for more information on any training courses offered.

Linux Command Line Tutorials

If you prefer to learn how to use the Linux command line on your own rather than attend an Introduction to Unix training session, then we recommend working through Ryan’s Linux Tutorial. Once you finish the first five sections, you will have enough Linux command line knowledge to use Artemis. If you’re willing to invest time to work through the whole tutorial, you will learn tricks to work more efficiently in Linux command line environments.

Access to Artemis

Artemis access is available to all researchers at the University of Sydney with a valid UniKey. Get an Artemis account by create a project with Artemis HPC access in Researcher Dashboard (DashR). Alternatively, if you’re a member of a research group that already has Artemis access, ask your Lead Investigator to add you to one of their projects with Artemis access in DashR.

Artemis is accessible via SSH using your UniKey and password using the hostname hpc.sydney.edu.au. Throughout the guide, we use the example UniKey abcd1234. Remember to replace abcd1234 with your UniKey wherever needed.

On-campus access

For Windows-based access you can use an SSH client like PuTTY.

On Linux or MacOS you can use the SSH command in the built-in terminal app. Start the Terminal app, then type the following command to log in:

ssh abcd1234@hpc.sydney.edu.au

Off-campus access

The recommended way of accessing Artemis from off-campus is by first connecting to the University VPN, then connecting to Artemis via SSH.

If you cannot use the VPN, you may instead connect via jump.research.sydney.edu.au (an intermediate host). First connect using an SSH client:

ssh abcd1234@jump.research.sydney.edu.au

After logging in, connect to Artemis by typing the following into your session:

ssh abcd1234@hpc.sydney.edu.au

If you wish to connect from jump.research.sydney.edu.au to Artemis without typing a password, set up passwordless SSH using SSH key pairs. First, login to jump.research.sydney.edu.au and type:

ssh-keygen

and accept all defaults. Then type:

ssh-copy-id abcd1234@hpc.sydney.edu.au

If successful, you will be able to log into Artemis from jump.research.sydney.edu.au without a password by typing:

ssh abcd1234@hpc.sydney.edu.au

Note

For security reasons, SSH key pairs cannot be used between your computer and jump.research.sydney.edu.au.

Project

You need to know your short project name, as specified in your Artemis HPC project in Researcher Dashboard (DashR). The names of your Artemis /project and /scratch directories and your Artemis jobs use this short project name.

There are two styles of project name you can use:

  • RDS-FAC-Project-RW (long project name)
  • Project (short project name)

Your long project name has the form RDS-FAC-Project-RW, where FAC is your faculty code and Project is your short project name as specified in your Artemis HPC project in DashR. If you have access to Artemis, but don’t know your project name, ask your Lead Investigator, or refer to your Artemis HPC project in DashR.

Throughout this guide, we will use the project PANDORA in the examples provided. Remember to replace PANDORA with your short project name in all examples.

Software

There are many pre-installed programs on Artemis, including various compilers, scripting languages (for example, Python, Perl and R), libraries and other specialised software. For full details, see the Software section. For a complete list of all installed software (updated monthly), see the Artemis Software List.

Opening GUI windows on Artemis

It is possible to open programs with a graphical user interface (GUI) on Artemis if you have an X server running on your computer and ssh into Artemis using either the -X or -Y options. Programs on Artemis with GUIs include gedit (a text editor), Matlab and Gnuplot.

Linux

If you are on a Linux computer, such as Ubuntu or Linux Mint, then you are already running an X server. Therefore, you can open programs with GUIs if you log into Artemis using the -X or -Y options.

ssh -X abcd1234@hpc.sydney.edu.au

MacOS

On MacOS, you need to install XQuartz. After installing XQuartz, you can then open a terminal window using MacOS’s built-in terminal program, then SSH to Artemis using the -X or -Y options, as was the case for Linux.

Windows

On Windows, there are a number of X servers to choose from. The University of Sydney has a site license for Starnet X-Win32. Download and install X-Win32, then use the new connection wizard to set up an Artemis connection:

  • Select SSH and give your connection a name. For example, “John’s Artemis connection”, then click next
  • Enter the hostname: hpc.sydney.edu.au
  • The login name and password are your UniKey credentials
  • In the command to run on remote host, type /usr/bin/xterm -ls -fa 'Consolas' -fs 11.
  • Click Finish

Your new connection will appear in your connections list. To start a command line session on Artemis, click the connection you just made, then click Launch. A command line terminal connection to an Artemis login node will open. If everything was done correctly, you will be able to launch programs such as gedit from the command line.

Text Editors

It is possible to edit text files on Artemis using text editors such as Nano, GEdit, Vim or Emacs. If you have logged into Artemis with an X server connection (that is, with the -X or -Y options to the ssh login command and a connection to an X server running on your computer), then you can use gedit to edit text files. If you don’t have an X server running, then the next simplest text editor is nano. If you find yourself editing text files frequently on Artemis and want to invest time to learn a more powerful text editor, then it is worth using either emacs or vim.
