How to run Jupyter notebooks remotely on HORDA?

Assuming jupyter is running on troll-4 (port 8888) and that the connection is established with sshuttle (see Getting started section for more details) it is possible setup the tunnel as follows:

ssh -NL 8888:localhost:8888 your_username@troll-4.sih-60.internal

Afterwards you should be able to see the running Jupyter instance via browser at the URL: http://localhost:8888

How to install python packages on HORDA?

python3 (3.9, 3.10 and 3.11) as well as python2 (2.7.18) along with the recent pip and venv are installed system-wide on each node of HORDA.

You can simply install packages either with pip install --user or use venv or svirtualenv (this will allow to handle multiple projects with possibly conflicting dependencies).

Finally, if you need newer versions of python or want to handle complicated dependencies you can install a local version of anaconda in your $HOME directory.

I want to use program XXX on HORDA, can I install it on my own?

You can install any software you like in your $HOME directory (as long as you have a valid license to use it).

If you need support in setup of some program or want it to be installed system-wide, please contact the administrators.
