Connecting

Important

Before trying to log in to any of the C3SE systems you need to be equipped with the following:

• Your username, called Chalmers ID (CID) with associated password. We give this to all users who lack it when they apply
• An account on each C3SE system you are going to use (i.e. Vera or Alvis). Everyone has to apply for an account, even if you already have a CID

If you lack any of this, please read the instructions on how to get access.

VPN

We don't allow all networks to directly connect.

Note

You may first want to check the legality of using VPN in your location before continuing.

• Vera is accessible via Chalmers and GU local network
• Alvis is accessible via SUNET networks (i.e. most Swedish university networks)

If you are on any other network (inside or outside Sweden) then you should use VPN to access. For Alvis, you can use your own Swedish university VPN if it is actually configured to send traffic via the VPN. You can test your VPN by checking that your public IP address matches your university.

Your own University VPN should always be the first choice and have your university IT-support help you with any issues. Only in cases where this is not possible, there is also a possibility to ask the Chalmers IT to be added to the Chalmers' eduVPN (email support@chalmers.se).

Connection options

There are three primary options for connecting to the cluster environments. ** NOTE ** Only SSH connections are meant for file transfer. Please check our pages on file transfer for details.

1. OpenOndemand portal for interactive compute sessions;
2. SSH connection for command line access to login nodes;
3. Remote Desktop Protocol (RDP) connection to the login nodes for light-weight graphical work, such as visually inspecting results;
