aiken.ce.pdn.ac.lk Server

This is a HPC (High Performance Computing) server of the Department of Computer Engineering, University of Peradeniya.

The administrator changes will be documented here.

You can use this server using the LDAP login for ce.pdn.ac.lk undergraduates (which is used for CO top floor lab, aiken and tesla) without sudo access.

Send an email to headce[at]eng.pdn.ac.lk with your registration number requesting an account in this server. If you are allowed to have one, head of the Department will forward the request to the server admin and you will recieve a login.

Ask headce[at]eng.pdn.ac.lk.

You can use ssh login. This is a good set of instructions on the matter. If it is not clear (or unaccessible), contact dhanushki.mapitigama[at]eng.pdn.ac.lk

Create a conda environment with jupyter notebook package installed.
Activate that environment.
Run
```
jupyter notebook --generate-config
```
It will say the configuration file for your account. Edit the configuration file and add the following two lines. (They are originally commented out as given below.)
```
# c.NotebookApp.allow_origin = ''
# c.NotebookApp.ip = 'localhost'
c.NotebookApp.allow_origin = '*'
c.NotebookApp.ip = '0.0.0.0'
```
Save the configuration file. You should still be in the conda environment.
Run the jupyter notebook.
```
jupyter-notebook --no-browser
```

You will see a URL like this
