Live Interaction

To bootstrap a virtual environment and run the notebook live:

1. Select an appropriate system to run the demo on. As written, the notebook runs two local tasks, as well as a remote task implemented as a Slurm batch job, so a system with the Slurm batch scheduler would be appropriate. The environment requires ~5.5 GB, so use a filesystem with sufficient quota.

2. Ensure that X forwarding is enabled and ssh to your selected system.

3. Ensure that x-www-browser is on your PATH. If not, create it as a symlink to the browser you’d like to use, e.g. firefox. You should be able to run x-www-browser and interact with the browser via X over ssh.

4. Clone this repo on the selected system.

5. In the repo, cd to the notebooks/ecflow directory and run ./start to build the environment, launch Jupyter, and interact with the notebook. You can edit the notebook cells in the browser. Depending on your needs, you might need to edit the files common.h and config.yaml externally.
