Tutorial Setup

The tutorial examples are installed with Ascent to the subdirectory examples/ascent/tutorial/. Below are several options for using pre-built Ascent installs and links to info about building Ascent. If you have access to Docker, the easiest way to test the waters is via the alpinedav/ascent Docker image.

Tutorial Cloud Option

For in person tutorials (at Supercomputing, the ECP Annual Meeting, etc), we provide HTTP access to several instances of our Ascent Docker image running the jupyter notebook server. We hand out IP addresses and login info to attendees during these events.

Using Docker

If you have Docker installed you can obtain a Docker image with a ready-to-use ascent install from Docker Hub. This image also includes a Jupyter install to support running Ascent’s tutorial notebooks.

To directly start the Jupyter Notebook server and run the tutorial notebooks, run:

docker run -p 8888:8888 -t -i alpinedav/ascent-jupyter

(The -p is used to forward ports between the container and your host machine, we use these ports to allow web servers on the container to serve data to the host.)

This image automatically launches a Jupyter Notebook server on port 8888. Assuming you forwarded port 8888 from the Docker container to your host machine, you should be able to connect to the notebook server using http://localhost:8888. The current password for the notebook server is: learn

To start the base image and explore the install and tutorial examples with bash, run:

docker run -p 8888:8888 -t -i alpinedav/ascent

You will now be at a bash prompt in you container.

To add the proper paths to Python and MPI to your environment, run:

source ascent_docker_setup_env.sh

The ascent source code is at /ascent/src/, and the install is at /ascent/install/. The tutorial examples are at /ascent/install/examples/ascent/tutorial/ and the tutorial notebooks are at /ascent/install/examples/ascent/tutorial/ascent_intro/notebooks/.

You can also launch the a Jupyter Notebook server from this image using the following:


The url (http://localhost:8888) and password (learn) are the same as above.
