First steps

To start using Tycho, please follow these steps

• Get a user account by contacting a sponsor and signing up at

https://hpc.ku.dk/account.html https://hpc.ku.dk/account.html

You have to select "Astro" as your group

• BE AWARE THAT THE WELCOME E-MAIL IS NOT CORRECT. Most important, you should never login to fend0X.hpc.ku.dk, but instead use the Tycho-specific frontends called astro0X.hpc.ku.dk (see Hardware for a list of available frontends).

• Set up an SSH key pair for secure passwordless login (see Accessing Tycho)

• Add module load astro to you $HOME/.bashrc file to have access to all the custom installed software.
• Consider changing umask 077 to umask 027 in $HOME/.bashrc to allow collaborators and/or your supervisor read access to your files when logged in to the cluster.
