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

You have to select "Astro" as your group. Remember to sign the rules-of-conduct-form

• BE AWARE THAT THE WELCOME E-MAIL IS NOT CORRECT. You should never login to fend0X.hpc.ku.dk, but instead use the Tycho-specific frontends called astro0X.hpc.ku.dk (see Hardware for an up to date list of available frontends / Analysis hardware).

• 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.

• If you are going to travel, but want to continue working on Tycho while you are travelling, you need to set up a Dynamic Firewall before travelling. You can do so by following the detailed instructions here
