4.4. Pipelining in PopXL

This tutorial on pipelining in PopXL is available as a Jupyter notebook.

To run the notebook in this folder:

  1. Install a Poplar SDK (version 2.6 or later) and source the scripts for both PopART and Poplar as described in the Getting Started guide for your IPU system.

  2. Install system dependencies: apt-get install -y $(< required_apt_packages.txt)

  3. Create a Python virtual environment: python3 -m venv <virtual_env>.

  4. Activate the virtual environment: . <virtual_env>/bin/activate.

  5. Update pip: pip3 install --upgrade pip

  6. Install requirements pip3 install -r requirements.txt (this will also install popxl.addons).

  7. Launch a Jupyter Server on a specific port: jupyter-notebook --no-browser --port <port number>. Be sure to be in the virtual environment.

  8. Connect via SSH to your remote machine, forwarding your chosen port: ssh -NL <port number>:localhost:<port number> <your username>@<remote machine>

On the machine connected to IPUs:

python3 -m venv virtual_env
. virtual_env/bin/activate
pip3 install --upgrade pip
pip3 install -r requirements.txt
pip3 install jupyter
jupyter-notebook --no-browser --port 12345

Take note of the URL displayed by the jupyter-notebook command.

On your local machine:

ssh -NL 12345:localhost:12345 <your username>@<remote machine>

Then navigate in your web-browser to the URL displayed by Jupyter in the previous step.
