 The Bluefog source code was based off `Horovod <https://github.com/horovod/horovod>`_ repository. Hence, BlueFog shared lots of common features from Horovod such as `timeline <https://bluefog-lib.github.io/bluefog/timeline.html>`_, tensor-fusion, etc. Here, we want to express our gratitude to the Horovod team.
