📝 Walkthrough

Walkthrough

Updates CI configuration to extend GPU test coverage by adding a new pytest invocation for tests/ops/simple_gla/pallas_vs_gpu/, while simultaneously excluding this test directory from TPU test execution to prevent duplication across test environments.

Changes

Cohort / File(s)	Summary
CI Test Configuration .github/ci/gpu-tests.sky.yaml	Adds new pytest invocation targeting tests/ops/simple_gla/pallas_vs_gpu/ with verbose output; removes trailing newline.
CI Test Configuration .github/ci/tpu-tests-job.yaml	Adds tests/ops/simple_gla/pallas_vs_gpu/ to pytest exclusion list to prevent test execution on TPU runner.

🐰 whiskers twitching with delight

GPU tests hop into the light,
While TPU tests step aside,
No duplication to confide!

Code Review

This pull request introduces new GPU tests for simple_gla and updates the CI configuration to include these tests in the GPU suite while excluding them from the TPU suite. The review feedback highlights a necessary path adjustment in the test scripts to account for the new directory structure and suggests adding strict marker validation to the pytest command to maintain consistency with existing CI tasks.

[gemini-code-assist]

The tests in tests/ops/simple_gla/pallas_vs_gpu/ have a broken sys.path configuration due to the directory move. They currently use parents[3] to locate the repository root, but since they are now one level deeper, they should use parents[4]. This will cause import errors when running these tests directly as scripts.

[gemini-code-assist]

The new pytest command is missing the -o "addopts=--strict-markers" option used in the previous test execution (lines 36-40). Including this ensures that any custom markers used in the new tests are correctly validated, maintaining consistency across the CI suite.

  python -m pytest \
    -o "addopts=--strict-markers" \
    tests/ops/simple_gla/pallas_vs_gpu \
