How to access the Aurora Cluster

The Aurora cluster is part of the SNIC infrastructure and is managed by Lunarc. This means that to access it, a user needs to have a SNIC account and has to join a specific project.

The current Lunarc login system is based on a one time password shared via mobile phone. This means that to access Aurora you must be able to receive SMS. Currently there is no other way of accessing the cluster.

Prerequisite: Get a SUPR account

Follow these steps:

  1. Create an account on https://supr.snic.se/
    1. :!: Insert your mobile phone information. It is needed to access aurora.
  2. Login and choose to join a project based on the table below
  3. Wait to receive a password from Lunarc
Your division Project Name URL
Nuclear Physics HEP 2016/1-3 https://supr.snic.se/proposal/4463/
Particle Physics HEP 2016/1-4 https://supr.snic.se/proposal/4465/
Theoretical Physics HEP 2016/1-5 https://supr.snic.se/proposal/4466/
Mathematical Physics LU 2016/2-10 https://supr.snic.se/project/4973/

SSH - Shell access

Once you have a SUPR account, you can login to Aurora using the username and password that Lunarc gave you, and remember that you need a mobile phone to complete access.

Required software:

On Linux or Mac, you should have the ssh client already installed. On Windows you can use putty and optionally some XWindows emulator. More info here: xwindowswithmswindows

Login procedure

access aurora via the hostname aurora.lunarc.lu.se, example:

 ssh -X username@aurora.lunarc.lu.se 

When asked about the OTP code, check your mobile phone and insert the code you just received.

You will be logged in to the frontend node. :!: NOTE: :!: it is NOT possible to run your code on the frontend node. This is a very big difference to Iridium. Your code can only run on the dedicated nodes. If you run stuff on the frontend you will be kicked out of the cluster. Please follow the guide running_on_aurora to know how to run your code.

Generic login documentation from Lunarc is here: http://lunarc-documentation.readthedocs.io/en/latest/login_howto/

Lunarc Graphical Desktop

Lunarc Graphical Desktop is a full desktop solution that runs in front of the cluster. You can start your jobs and have your text editors always open and just disconnect. Every time you log back in you will have your work environment already up and running.

Information how to use and access this feature is here: http://lunarc-documentation.readthedocs.io/en/latest/using_hpc_desktop/
