From 2175ecfe894585a9086a7dc4bbb4e7f96423f9e4 Mon Sep 17 00:00:00 2001 From: Charlie Truong Date: Sun, 26 Apr 2026 11:22:28 -0500 Subject: [PATCH 01/61] ci: shard unit tests from 3 to 9 parallel jobs for faster CI Restructure unit test CI from 3 monolithic shards (Generation, Policy, Other) into 9 targeted shards split by extra/marker. Each extra-specific shard (mcore, automodel, vllm, sglang, nemo_gym) runs a single --*-only flag across all unit tests, while domain shards (models, environments, algorithms, other) run only base (unmarked) tests. This eliminates the 5-6 sequential pytest invocations per shard, reduces the bottleneck from 90 min (Policy) to ~30 min per shard, and makes it clear where new tests should be added. New shards: - L0_Unit_Tests_Vllm: base vllm generation + --vllm-only catch-all - L0_Unit_Tests_Sglang: base sglang files + --sglang-only catch-all - L0_Unit_Tests_Mcore: --mcore-only catch-all - L0_Unit_Tests_Automodel: --automodel-only catch-all - L0_Unit_Tests_Nemo_Gym: --nemo-gym-only catch-all - L0_Unit_Tests_Models: base model tests (minus generation) - L0_Unit_Tests_Environments: base environment tests - L0_Unit_Tests_Algorithms: base algorithm tests - L0_Unit_Tests_Other: catch-all for remaining base tests + research Also fixes run_unit.sh to treat pytest exit code 5 (no tests collected) as success, preventing shard failures when FAST exclusions remove all tests from a shard.

Previously, each parametrized test (training×7, generation×2, logprobs×6, topk×6 = 21 tests) created and destroyed its own RayVirtualCluster. Now they share a single class-scoped cluster, saving ~20 cluster creation/teardown cycles. Each test still creates and destroys its own Policy for isolation. Standalone tests (checkpoint, loss_independent, grad_norm, etc.) remain outside the class since they need custom cluster configs. Estimated savings: ~5-10 minutes from avoided cluster overhead.
