Overview

Draft until #58795 merges. Enrolls the three Language Models steps that build mamba-ssm and causal-conv1d from source, and their AMD mirrors, in automatic_shard (6 jobs). The source builds take most of a job's setup, and every shard would repeat them; #58795 prebuilds both in the test image, after which sharding these pays for itself. Part of the series that enrolls every remaining test step (#64590-#64599).

Claims

Step Change AMD mirror
language-models-test-extended-generation enrolled enrolled
language-models-tests-granite-l4-compatibility enrolled enrolled
language-models-tests-hybrid fixed 2-way pytest-shard split becomes automatic same

Validation

Details

  • Hybrid drops parallelism: 2 and its --num-shards/--shard-id flags (step and mirror), so the planner owns the split.
  • Timeouts unchanged.
