Benchmarking for pvlib-python

The benchmark timings are hosted on this repo's github pages.

Setting up a new nightly runner

The following commands should be executed in a Anaconda Prompt:

1. Navigate to your preferred directory for saving github repositories.

2. Clone the pvlib-python github repository:

   • git clone https://github.com/pvlib/pvlib-python.git

3. Clone this github repository:

   • git clone https://github.com/pvlib-benchmarker/pvlib-benchmarks.git

4. Create and activate a new conda environment:

   • conda create -n pvlib-asv python=3.7
   • conda activate pvlib-asv

5. Install airspeed velocity:

   • pip install asv==0.4.2

6. Install pvlib so that the benchmark files can be imported:

   • pip install ./pvlib-python[all]

7. In the pvlib-benchmarks repo directory, set the git user info:

   • git config user.name 'pvlib-benchmarker'
   • git config user.email '[email protected]'
   • Note: it seems like asv gh-pages ignores the repo-level configuration, so it might be necessary to set these parameters globally (e.g. use git config --global user.name 'pvlib-benchmarker').

8. Also configure the remote URL to use ssh so pushing results doesn't require you to enter your username/password:

   • git remote set-url origin git+ssh://[email protected]/pvlib-benchmarker/pvlib-benchmarks.git

9. Create an ssh key, register it with ssh-add ..., and configure it with GitHub. This is so the nightly job can push to GitHub without needing the user to authenticate manually.

10. Navigate to the 'benchmarks' folder in the cloned 'pvlib-python' repository.

11. Set the machine information:

    • asv machine

12. Validate and build environments (may take a couple minutes to run):

    • asv check

13. Do a quick test run to verify that things seem to be working:

    • asv dev

14. Establish a benchmark history, for example:

    • asv run v0.6.0..v0.7.2

15. Finally, enable the nightly job in whatever job scheduler you are using. A suitable starting point for a crontab entry might be:

    • 0 0 * * * $HOME/pvlib-benchmarks/cronjob.sh > $HOME/logs/`date +\%Y-\%m-\%d`-cron.log 2>&1

    If using systemd units, copy the files pvlib_benchmarks.service and pvlib_benchmarks.timer files to the ~/.config/systemd/user/ directory (create it if needed). Useful commands:

    • systemctl --user daemon-reload
    • systemctl --user list-timers
    • systemctl --user status pvlib_benchmarks.timer
    • systemctl --user start pvlib_benchmarks.timer
    • journalctl -xe
