Unit and Integration Testing

workflow file	action	accelerator*
.github/workflows/ci-tests-pytorch.yml	Run all tests except for accelerator-specific, standalone and slow tests.	CPU
.azure-pipelines/ipu-tests.yml	Run only IPU-specific tests.	IPU
.azure-pipelines/hpu-tests.yml	Run only HPU-specific tests.	HPU
.azure-pipelines/gpu-tests-pytorch.yml	Run all CPU and GPU-specific tests, standalone, and examples. Each standalone test needs to be run in separate processes to avoid unwanted interactions between test cases.	GPU
.azure-pipelines/gpu-benchmark.yml	Run speed/memory benchmarks for parity with pure PyTorch.	GPU
.github/workflows/tpu-tests.yml	Run only TPU-specific tests.	TPU

• *Accelerators used in CI

  • GPU: 2 x NVIDIA RTX 3090
  • TPU: Google GKE TPUv3
  • IPU: Colossus MK1 IPU
  • HPU: Intel Habana Gaudi SYS-420GH-TNGR which has 8 Gaudi accelerators

• To check which versions of Python or PyTorch are used for testing in our CI, see the corresponding workflow files or checkgroup cofig file at .github/checkgroup.yml.

Documentation

Bots

workflow file	action
.github/mergify.yml	Label PRs as conflicts or ready, and request reviews if needed.
.github/stale.yml	Close inactive issues/PRs sometimes after adding the "won't fix" label to them.
.github/workflows/probot-auto-cc.yml, .github/lightning-probot.yml	Notify maintainers of interest depending on labels added to an issue We utilize lightning-probot forked from PyTorch’s probot.
.github/workflows/probot-check-group.yml, .github/checkgroup.yml	Checks whether the relevant jobs were successfully run based on the changed files in the PR
.pre-commit-config.yaml	pre-commit.ci runs a set of linters and formatters, such as black, ruff and isort. When formatting is applied, the bot pushes a commit with its change. This configuration is also used for running pre-commit locally.
.github/workflows/labeler.yml, .github/labeler.yml	Integration of https://github.com/actions/labeler
