Description

Temporarily waive 11 failed case(s) on DGX_B200. Opened automatically by auto-waive (draft; a human reviews and merges).

The native main-break detector (native-p3/k3-w12h-fresh12h-nopass-hostclock/1.0.1) reports unittest/_torch/attention/sparse/deepseek_v4/test_deepseek_v4_fp4_indexer.py::test_fused_indexer_q_uses_serial_prepare broken on main for DGX_B200: failure signature failed on teardown with runtimeerror: invalid argument to exchangedevice, onset 2026-11-05T08:45:49Z, latest failure 2026-11-05T08:52:47Z. Policy native_p3@1.0.0 selected it; https://nvbugs/7050983 tracks the fix. Scope DGX_B200 is the stage prefix that ran the failing test.

• Bug: https://nvbugs/7050983 (details, logs and 7-day test history are in the bug)
• Restore coverage when: Remove this line when https://nvbugs/7050983 is fixed or closed and the test passes on DGX_B200 post-merge; un-waive follows the bug, not the PR.
• Scope reviewed by: auto-waive at 2026-11-05T12:05:48.558424+00:00

What to check before merging:

• The bug's test-history links show the cases failing on main, not only on the trigger PR.
• The scope DGX_B200 matches the failing stage and no narrower waiver already exists.
• Nothing else is needed from you after merging: the bug owner removes these lines with the fix.
