Accessing UTA HEP Cluster

Here we assume that you have already requested had have been granted an account on the UTA HEP Cluster.

Labs, Homeworks, and Exams for the course will be in the form of Jupyter Notebooks that are served from the UTA HEP Cluster to your browser. The cluster is behind a firewall and can only be accessed via ssh. Therefore, in order to access the JupyterHub server, you will need to use ssh tunneling, as detailed below.

Mac/Linux:

Open a terminal. If you don't know how to do this on the MacOS, just click on the SpotLight magnifying glass and type "terminal". Once the terminal window opens, you can add it to you dock if you wish.

  • Type: (replace <username> with your username)
ssh -NfL 8000:127.0.0.1:8000 <username>@orodruin.uta.edu

  • Point your browser to 127.0.0.1:8000.

  • Log in.

Windows:

You will need to download plink.exe to establish the ssh tunnel. plink is part of putty which is a nice ssh/terminal client for windows and can be downloaded from here, if you want everything.

  • Download putty or just plink, which is all you will need, from here. Depending on your browser and its configuration, it is likely that the file is downloaded into a "Downloads" directory in your windows user account. You are free to copy it else where.

  • Open command prompt. If you don't know how, just type "command" into the Windows search box on the bottom left of the screen.

  • Navigate to where you have plink.exe.

  • Type: (replace <username> with your username)

plink.exe -N -L 8000:127.0.0.1:8000 <username>@orodruin.uta.edu

and enter you password. If everything works you will not get an error message nor the prompt back.

  • Point your browser to 127.0.0.1:8000

  • Log in.

Navigate to the Labs

  • If this is the first time you are logging into the system, you will see a listing of your home directory on the cluster. Click on the "Start Here" notebook (Start Here.ipynb).

  • Execute the cells in the notebook by pressing shift-enter. The notebook will clone this GitHub repository, installing the notebooks for the course.

  • Go back the the tab listing your home directory.

  • Navigate and start the first lab: MyLabs/Labs/Labs-0/Lab-0.ipynb.
