Included review availability: Your plan provides up to 12 included reviews per hour; 10 remain after this review. 📝 WalkthroughWalkthroughChangesSlurmSystem now owns job submission, job-ID parsing, and environment validation. Slurm runners and Docker image caching use these APIs. Tests cover centralized submission and SBATCH-based image imports. Slurm submission and image caching
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~45 minutes Change: Refactor Merge Risk: 🟡 Moderate · up to Some Slurm installations may pass validation but fail when single-sbatch workflows run, while concurrent image-cache attempts can overwrite diagnostics or interfere with each other. These risks should be addressed before merging. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Inline comments:
In `@src/cloudai/systems/slurm/docker_image_cache_manager.py`:
- Around line 152-164: Update cache_docker_image’s successful cache path to
remove the generated import script and Slurm output/error artifacts after
confirming the Docker image was cached. Keep those artifacts intact on failure
paths, including submit errors or unsuccessful imports, so debugging remains
possible.
In `@src/cloudai/systems/slurm/slurm_system.py`:
- Around line 132-140: Add "scontrol" to the _REQUIRED_BINARIES tuple used by
SlurmSystem.validate_install_environment(), so SlurmInstaller prerequisite
checks reject installations missing the command required by
SingleSbatchRunner.get_global_env_vars().
- Around line 132-148: Update the centralized required-binaries validation
associated with _REQUIRED_BINARIES to include enroot, ensuring installation
checks detect environments where the Docker cache job’s enroot import cannot
run.
In `@tests/test_docker_image_cache_manager.py`:
- Around line 85-101: Add a parameterized test for cache_docker_image covering
missing-image stderr values “Disk quota exceeded” and a generic error. Mock
SlurmSystem.submit_sbatch to write stderr to script_path.with_suffix(".err") and
return normally, then assert the result is unsuccessful and contains the
expected disk-specific or generic message.

97-101: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winGenerate collision-resistant cache job names.
The same image URL produces the same name for every call in one second. A failed import retains its script, but an immediate retry overwrites that script. Concurrent imports also share the same stdout and stderr paths. Add a random suffix to the job name.
Proposed fix

Summary
End goal - add optional Slurm REST API support. This is the first PR towards this goal - move all slurm communicated under Slurm class.
Test Plan
Additional Notes
Docker image installation on Slurm now happens through dedicated sbatch job rather than plain srun. This is needed to unify interfaces for all client code of SlurmSystem class
