### What does this PR do? Type of change: Test infra improvement <!-- Use one of the following: Bug fix, new feature, new example, new tests, documentation. --> * Instead of spawning multiprocesses per test case (adds ~10s overhead x 150 tests), we spawn once per file (gpu_megatron) or session (gpu) to make the tests much much faster * Remove some unused / unnecessary tests * Fix and enable Minitron NAS test on Hybrid models for Mcore 0.16 Test time (`pytest tests/<test_type>`) on 2x RTXPro 6000 Blackwell: https://github.com/NVIDIA/Model-Optimizer/actions/runs/22625069275 | | gpu | gpu_megatron | |------------|-----|--------------| | **Before** | 27m | 40m | | **After** | 16m | 19m | Full PR-merge CI/CD now only takes ~45mins ### Testing <!-- Mention how have you tested your change if applicable. --> Tested on 1,2,4,8 GPU setup ### Before your PR is "*Ready for review*" Make sure you read and follow [Contributor guidelines](https://github.com/NVIDIA/Model-Optimizer/blob/main/CONTRIBUTING.md) and your commits are signed (`git commit -s -S`). Make sure you read and follow the [Security Best Practices](https://github.com/NVIDIA/Model-Optimizer/blob/main/SECURITY.md#security-coding-practices-for-contributors) (e.g. avoiding hardcoded `trust_remote_code=True`, using `torch.load(..., weights_only=True)`, avoiding `pickle`, etc.). - Is this change backward compatible?: ✅ <!--- If ❌, explain why. --> - If you copied code from any other source, did you follow IP policy in [CONTRIBUTING.md](https://github.com/NVIDIA/Model-Optimizer/blob/main/CONTRIBUTING.md#-copying-code-from-other-sources)?: N/A <!--- Mandatory --> - Did you write any new necessary tests?: ✅ <!--- Mandatory for new features or examples. --> - Did you update [Changelog](https://github.com/NVIDIA/Model-Optimizer/blob/main/CHANGELOG.rst)?: N/A <!--- Only for new features, API changes, critical bug fixes or backward incompatible changes. --> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Chores** * Reworked GPU test infra to use a persistent distributed worker pool with improved per-worker teardown, aggregated error reporting, Megatron-specific cleanup, reduced GPU CI timeouts, and a small build-system dependency change. * **Tests** * Converted many multi-process GPU tests to a fixture-driven distributed runner, updating test entry points and orchestration while preserving test logic; adjusted imports and conditional guards for several GPU tests. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Keval Morabia <28916987+kevalmorabia97@users.noreply.github.com>
