# B200 Smoke Tests CI Workflow
#
# This workflow runs smoke tests on B200 hardware
#
# Flow:
# 1. Builds PyTorch with CUDA 12.8+ and sm100 architecture for B200
# 2. Runs smoke tests on linux.dgx.b200 runner
# 3. Tests executed are defined in .ci/pytorch/test.sh -> test_python_smoke() function
#
# Triggered by:
# - Pull requests modifying this workflow file
# - Manual dispatch
# - Schedule (every 6 hours)
# - Adding ciflow/b200 label to a PR (creates ciflow/b200/* tag)
