This article will guide you to run the Jupyter Notebook via Mamba on the LANTA HPC system, which requires ssh tunneling to the LANTA HPC. An overview of the content can be found in the table of contents below for immediate visualization of the interesting parts.

Table of Contents

Creating an environment to run the Jupyter Notebook

Load Mamba module

  1. Use the ml av Mamba command to see which version of Miniconda Mamba is available on the LANTA HPC system.

  2. Use the ml Miniconda3Mamba/xx.xx.x command to load the Miniconda version that you want to use. If you don't specify a version, the default version (D) is loaded, which is Miniconda3/22.11.1-1.

Conda environment

...

Use the conda create -n myenv commands to create the conda environment with myenv name.

...

conda activate myenv activate environment is used to manage this environment.

...

  1. xx.xx.x command to load the Mamba version that you want to use. If you don't specify a version, the default version (D) is loaded, which is Mamba/23.11.0-0.

Running Jupyter Notebook with Slurm script

There are 3 steps to run Jupyter Notebook on LANTA HPC.

1. Submit your job and read your slurm-xxxxx.out

Code Block
username@lanta:~> sbatch script.sh
username@lanta:~> cat slurm-xxxxx.out
    Jupyter server is running on: x1001c7s7b0n0
    Job starts at: Thu 28 Mar 2024 11:00:53 PM +07

    Copy/Paste the following command into your local terminal
    -------------------- /lantafs/data/home/ywongnon/.local/easybuild/modules/all ---------------------------------------------------
   Miniconda3/4.8.3    Miniconda3/4.9.2    Miniconda3/4.12.0 (D)-----
    Where:ssh    D:  Default Module

Use "module spider" to find all possible modules.
Use "module keyword key1 key2 ..." to search for all possible modules matching any of the "keys".

[username@lanta-frontend-1 prep]$ ml

Currently Loaded Modules:

[username@lanta-frontend-1 prep]$ conda create -n myenv
[username@lanta-frontend-1 prep]$ conda activate myenv
(myenv) [username@lanta-frontend-1 prep]$

pip install jupyterlab etc.

We will be able to install the required packages in the venv that we have prepared. This will vary depending on the needs of each project. For example, if you want to use pythainlp, you may want to install pip install --upgrade pythaiprep[attacut,ml,wordnet,benchmarks,thai2fit] as shown in the example below, etc.

Info

You can skip this step if you don't want to use pythainlp.

Reserve HPC resources for interactive use.

Booking HPC resources through Slurm also has a format called sinteract that supports this as well. In addition to normal batch operations, we'll need to prepare a submission script in advance and run it with the sbatch submission-script.sh command.

sinteract - default

$ sinteract

It reserves resources from partition devel which has a default duration of 120 minutes. Since partition devel is configured to use compute node machines 001 and 002, if we use this option, we usually get lanta-c-001 or lanta-c-002.

Info

You can learn more about the characteristics of each partition from the scontrol show partition command in LANTA.

When we order sinteract in continuation from the above, it changed from lanta-frontend-1 node to the resource, which is the lanta-c-001 machine.

Code Block
(myenv) [username@lanta-frontend-1 prep]$ sinteract
...
[username@lanta-c-001 prep]$

sinteract - more options

$ sinteract -p compute -N 1

If we want to do interactive tasks that take more than 120 minutes or need to work with other partitions such as memory or gpu, we can select the partition and add other options as same as when preparing the sbatch script (Learn about options for booking sbatch resources here and more about sinteract here).

Code Block
[username@lanta-frontend-1 ~]$ sinteract -p compute -N 1
...
[username@lanta-c-059 ~]$

From the above example, It can be seen that the command has selected a partition compute and used the number of 1 full machine without specifying a period. Resulting in the lanta-c-059 to be used differently from using the default option as shown earlier.

Running Jupyter Notebook via ssh tunnelling

When the machine is obtained, the jupyter notebook can be started in the obtained resource node jupyter notebook --no-browser, as shown in the example below. We need to enter 3 windows, as following.

  • Terminal 1 - jupyter notebook --no-browser

  • Terminal 2 - ssh tunneling from local to HPC

  • browser 1 - make a connection through the port that we tunneled to find the notebook that we opened on LANTA HPC.

  • (Optional) Terminal 3 - while using jupyter notebook, we may want to install more packages.

Terminal 1 - jupyter notebook --no-browser

    To access the notebook, open this file in a browser:
        file:///lantafs/data/home/username/.local/share/jupyter/runtime/nbserver-24757-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=58bfd7de821a8722c4e07c0eafad519c868f375e61285982

We can see that jupyter uses port 8888 and lets us connect to jupyter notebook via URLs: http://localhost:8888/?token=58bfd7de821a8722c4e07c0eafad519c868f375e61285982 If we use this link now, it still won't open because we haven't done ssh tunneling yet (next step).

Note

Keep this terminal page open to run the jupyter notebook process.

Terminal 2 - ssh tunneling from local to HPC

At the terminal screen of the local machine, perform a ssh tunneling connection to the HPC using the command below. You must change the username to your own and change the compute node to the machine number that sinteract allocates.

...

@mylocalmachine:~ $

@mylocalmachine:~ $ ssh -J <username>@lanta.nstda.or.th -L 8888:localhost:8888 -N <username>@<the machine number allocated by sinteract.>

In this example, the machine number allocated by sinteract is lanta-c-001.

Code Block
$ ssh -J apiyatum@lanta.nstda.or.th -L 8888:localhost:8888 -N apiyatum@lanta-c-001
(apiyatum@lanta.nstda.or.th) Password: 
(apiyatum@lanta-c-001) Password:

We have to enter the password to connect to LANTA and enter the password again to connect to the allocated compute node (lanta-c-001), then the screen freezes.

Note

Keep this terminal page open.

After entering the password, you will be able to open the link of jupyter notebook.

Browser 1 - to go through tunneling port for jupyter notebook

...

http://localhost:8888/?token=58bfd7de821a8722c4e07c0eafad519c868f375e61285982

Using the url obtained when starting the application in Terminal 1

...

(Optional) Terminal 3 - install additional packages or corpus

Open another terminal screen, connect to LANTA's Frontend Node and enter the environment we are currently using for our jupyter notebook (myenv).

Note

Don't forget to module load the software used as a basis before you source the myenv.

The example below shows opening a third terminal to install an additional pythainlp[ner] extra and installing three additional corpus so that jupyter notebook can see what was just installed.

    Or copy and paste one of these URLs:
        http://x1001c7s7b0n0:60151/tree?token=13acf46197090432de43db8f65d8651361ad319861bd04f5

2. Copy/Paste the following command into your local terminal for ssh tunneling to the LANTA HPC

Code Block

...

Info

If you don’t have a private key (id_rsa file), you can use only the ssh -L 8714:x1000c2s0b0n0:8714 username@lanta.nstda.or.th command to access the LANTA HPC with your password and verification code.

3. Open a browser on your local machine with the following address (Final line in slurm-xxxxx.out) 

Code Block
http://127.0.0.1:60151/tree?token=13acf46197090432de43db8f65d8651361ad319861bd04f5

Shutting down the Jupyter Notebook

When you’re done with the Jupyter Notebook session, you can start the shutdown process by closing the browser and terminal on your local machine. Then, you must cancel your job in the Slurm system of the LANTA HPC with the scancel JOBID command.
