Subsystem graph generation for environment modules
Project description
Compspec Modules
A compspec (Composition spec) is a specification and model for comparing things. Compspec modules is a plugin for extraction of environment modules subsystem metadata about software installed on a system. This can be for the entire system or a user-specific install. The plugin exports json graph format (JGF) that can be used for scheduling and other purposes. To learn more:
- Compspec: the Python library that discovers and loads this plugin.
Note that I'm currently parsing environment modules, and very simply. We can extend to more complex / LMOD if needed.
Usage
Install compspec and the plugin here:
pip install compspec
pip install compspec-modules
Here is an easy way (in the devcontainer) to get a bunch of testing modules.
git clone https://github.com/shawfdong/modulefiles /tmp/modulefiles
export MODULEPATH=$MODULEPATH:/tmp/modulefiles
Then run an extraction with spack. You will want to provide the root to the spack install to describe:
compspec extract modules
To save to file:
compspec extract --outfile module-subsystem.json modules

Development
If you open the Development container in VSCode, you'll find environment modules are installed:
$ module avail
This allows us to easily develop and test the compatibility plugin.
