Guides and Scripts for LANTA

Scripts for initalizing Jupyter Server

This script will help you to install Jupyter Server on your server.

ssh <name>@lanta.nstda.or.th

# for high-bandwidth and downloading files
ssh <name>@transfer.lanta.nstda.or.th

Initializing the submit script

Note: SSH into the server as the user created in the previous step first.

mkdir scripts
cd scripts

wget https://github.com/Kentakoong/init-cloudtraining/releases/download/LANTA-1.0.2/setup.sh

bash setup.sh

Then follow the interactive prompt to setup the Jupyter Server.

Inspecting the Jupyter Server when script finishes

After the script finishes, check your queue to see if the script has been submitted.

myqueue

If the script has been submitted, check your current directory with ls to see the slurm file.

ls

cat slurm-xxxxxx.out

The slurm file will contain the URL to access the Jupyter Server.

Accessing the Jupyter Server

To access the Jupyter Server, copy the URL from the slurm file and paste it into your browser.

ssh -L <PORT>:<HOST>:<PORT> <username>@lanta.nstda.or.th -i <path-to-private-key>

Then open your browser and go to localhost:<PORT>
or copy the URL with the token from the slurm file and paste it into your browser.

Stopping the Jupyter Server

To stop the Jupyter Server, go to the terminal where you ran the batch script.

Run the following command to see the job ID.

myqueue

Then run the following command to stop the Jupyter Server.

scancel <job-id>

To Install Packages or create Environments, use the compute node to install

ssh <username>@transfer.lanta.nstda.or.th

Then run the following command to SSH into the compute node.

bash setup.sh

myqueue

ssh lanta-c-xxx

conda create --name <env-name> --clone <source-env>

To install packages

conda activate <env-name>

# To install a package
conda install <package-name>

# To install a package from a requirements file
pip install --file requirements.txt
