What does this PR do?

Puzzletron campaign launches can accept misspelled fields, conflicting aliases, and scheduler settings that only fail after work is submitted. This change validates experiment, runner, and execution contracts before launch, preserves supported compatibility aliases, and produces portable Slurm plans with explicit log, partition, and shell-free process behavior.

Type of change: new feature

Review map

  1. Configuration loading rejects unknown or malformed fields, unresolved interpolation, incompatible aliases, and unsupported override forms with actionable errors.
  2. Campaign compilation normalizes stage resources and partitions, keeps attempt logs in one configured location, and runs controller subprocesses without a shell.
  3. Setup bundles, examples, and reorganized documentation generate the validated contract and explain environment setup, overrides, Slurm configuration, operations, and migration from the legacy campaign.

Testing

  • pre-commit run --all-files for formatting, Ruff, Mypy, YAML, license, Bandit, and Markdown checks.
  • Focused Puzzletron unit suites for configuration loading, plan compilation, executors, reporting, portable configs, setup bundles, wizard resolution, and example runner behavior.
  • .venv/bin/python -m pytest -q tests/unit/torch/puzzletron on CPU. Two unchanged-path width-slice tests failed because of inherited dependency behavior: the compact GDN failure reproduces identically on the target, while the AutoModel mask failure occurs only after the full suite and passes in isolation. A full target-suite comparison was not run.

No live Slurm submission or GPU campaign was run.

📝 Walkthrough

Walkthrough

Puzzletron now validates configuration strictly, supports unified Slurm partition lists, centralizes process execution and logging, updates setup generation, improves CLI errors, and adds dedicated operational documentation.

Changes

Puzzletron orchestration

Layer / File(s) Summary
Configuration contracts and validation
modelopt/torch/puzzletron/_config_aliases.py, modelopt/torch/puzzletron/orchestration/{compiler,config,schema}.py, puzzletron_setup/v2/{defaults,resolved,wizard}.py, tests/unit/torch/puzzletron/test_orchestration_compiler.py
Adds strict schema checks, compatibility-alias validation, partition normalization, execution-stage validation, override validation, and final-report routing.
Process execution and runtime orchestration
modelopt/torch/puzzletron/orchestration/{process,executors,adapters,controller,reporting}.py, tests/unit/torch/puzzletron/test_orchestration_executors.py
Adds shell-free run_argv, optional Slurm partition emission, shared log-directory handling, partition metadata precedence, and configured final-report execution.
Setup wizard and bundle generation
puzzletron_setup/{bundle.py,wizard.py}, puzzletron_setup/v2/{bundle.py,wizard.py}, tests/unit/torch/puzzletron/test_setup_*.py
Uses unified partition settings, assigns CPU resources independently, removes sequence_parallel from generated meshes, and quotes generated commands.
CLI and operational documentation
examples/puzzletron/orchestrate.py, examples/puzzletron/README.md, examples/puzzletron/docs/*, tests/unit/torch/puzzletron/test_orchestration_lightweight.py
Documents setup and operations in dedicated guides and reports configuration and dry-run failures with exit code 2 without tracebacks.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to f71a2

Some invalid campaign and setup inputs can still produce raw tracebacks, relative log paths may resolve outside the configured campaign directory, and CLI tests can hang without per-test timeouts. These are bounded but concrete merge-readiness issues, so the PR requires owner awareness or fixes before merging.

Redirect stderr when documenting tee capture.

OrchestratorLogger writes progress logs to stderr, as stated by the CLI help in examples/puzzletron/orchestrate.py. A command that only pipes stdout to tee will not capture the progress table or timestamped log updates.

Show 2>&1 | tee ... in the example, or state that stderr must be redirected.

Handle plan-build RuntimeError as a CLI configuration error.

compile_campaign_plan() can reach the plan() method in modelopt/torch/puzzletron/orchestration/adapters/post_mip.py. That method raises RuntimeError when an evaluation stage has no candidate architectures. This exception is not in the handler, so the CLI prints a traceback instead of logging the error and returning status 2.

Catch a dedicated plan/configuration exception, or map this known validation failure to the existing error path without masking controller runtime failures.

Slurm sbatch --output relative path resolved current working directory at submission versus job cd

💡 Result:

When you use a relative path for the --output (or --error) option in an sbatch command, Slurm resolves that path relative to the submission directory—that is, the current working directory where you executed the sbatch command [1][2][3]. This behavior remains consistent regardless of whether you include a cd command within your batch script to change the working directory during the job's execution [2]. Because Slurm parses the --output directive at the time of submission to prepare the I/O redirection, changes to the working directory made later inside the script do not affect the resolution of the output file path [2]. If you need the output file to be located in a directory relative to the job's execution directory (after a cd), you have two primary options: 1. Use absolute paths for the --output directive [2]. 2. Use environment variables like $SLURM_SUBMIT_DIR in your path definition if you are writing a script that needs to behave dynamically, or simply construct the desired output path to point to a directory that is guaranteed to exist on the compute nodes [4][5][3]. Note that Slurm does not automatically create directories for you [2]. If you specify a relative path (e.g., --output=results/job.out), the directory results/ must already exist in your submission directory, or the job will fail to open the output file [2][4].

Anchor relative log_dir values to puzzle_dir.

When runner.slurm.log_dir is relative, CampaignPlan.log_dir remains relative. SlurmExecutor passes it to #SBATCH --output, which Slurm resolves from the submission directory even after the batch script changes to repository. With log_dir: puzzle_runs/logs, logs can therefore be created outside puzzle_dir. Resolve relative values against puzzle_dir.

Wrap partition normalization errors in SetupError.

normalize_slurm_partition raises TypeError or ValueError. Every other invalid input in this resolver raises SetupError, which puzzletron_setup shows without a traceback. An invalid stage partition in the wizard state now escapes as a raw ValueError with a full traceback.

Both new CLI tests call subprocess.run without a timeout. If the orchestrator CLI blocks on either invocation, the test hangs until the suite-level timeout fires instead of failing on its own. Add a bounded timeout to each call.

  • tests/unit/torch/puzzletron/test_orchestration_lightweight.py#L319-L335: add timeout=120 to the subprocess.run call in test_orchestrator_cli_reports_config_errors_without_traceback.
  • tests/unit/torch/puzzletron/test_orchestration_lightweight.py#L384-L402: add timeout=120 to the subprocess.run call in test_orchestrator_cli_reports_dry_run_adapter_errors_without_traceback.

As per coding guidelines: "Respect the per-test timeout."
