This demo is part of A Example Pipeline for Unattended Pipelines, Data Transfer, and Computation Using Globus. Out of all the demos, this should be watched first.

NOTE: Long pauses (in excess of 10 seconds) have been removed.

To begin, we need a Python virtualenv on the cluster. The virtualenv needs the globus-compute-sdk package (to support Function registration), and the globus-compute-endpoint package (for the Globus Compute Endpoint software).

Here are the commands to run, to reproduce the demo in your own session:

NOTE: On SCG, Python versions are provided through Lmod modules. Every example assumes that you have already loaded the python/3.11.1 module.

# Create a venv for our Compute Endpoint and Compute Function
mkdir globus_compute_endpoint
/scg/apps/software/python/3.11.1/bin/python -m venv --upgrade-deps globus_compute_endpoint

# Activate the venv, and confirm `python` is pointing to the venv's Python.
cd globus_compute_endpoint
. bin/activate
which python
python -V

# Install the Globus Compute SDK and the Globus Compute Endpoint packages
pip install globus-compute-sdk globus-compute-endpoint

The next demo is Register the Function with Globus Compute.

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="/assets/asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="/assets/asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/725655.cast',
      document.getElementById('player'),
      { cols: 132, rows: 24 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/725655 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif
