Check your account username and token

If this is the first time that you're accessing MeluXina, you have received an email with your login information. This email (example on the right) includes two important pieces of information to set up your account:

• Your account username, in the format u10XXXX
• Your token (temporary password), in the format 123456

Then, you have to follow the link in the email, use your temporary credential to login and setup a new strong password. Make sure to remember your username and this password as you will need them later on.

Web-portal access

The Open OnDemand web portal provides a graphical interface to access MeluXina services. It serves as a web-based gateway to the high-performance computing (HPC) environment, allowing users to seamlessly access the command line, manage files, monitor jobs, and run graphical applications directly from a browser without needing to configure SSH locally.

Follow these steps to access the MeluXina Open OnDemand web-portal:

1. Open the url of the web-portal: https://portal.lxp.lu/.
2. Enter your username (u10XXXX) and password (set during onboarding)
3. If you have enabled 2FA, you'll be prompted for a one-time code
