Summary of Changes
Hello @happyandslow, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly improves the command-line interface (CLI) of the benchmark.py script by enabling a standard help flag and providing more comprehensive and readable documentation for its arguments. This makes the script's usage more intuitive and discoverable for anyone running benchmarks.
Highlights
- CLI Usability: The
benchmark.pyscript now supports the standard--helpflag, allowing users to easily view available command-line arguments and their descriptions directly from the terminal. - Improved Argument Documentation: The help message for the
--stageargument has been enhanced to provide a more detailed and clearly formatted list of all available benchmark stages (all,dataset,workload,client,analysis), improving clarity for users.

Code Review
This pull request improves the help message for the benchmark script, making it more user-friendly. My review includes a suggestion to further enhance the argument parsing by using argparse's built-in choices parameter for the --stage argument. This will add automatic validation and make the script more robust.
| parser = argparse.ArgumentParser(description="Run benchmark pipeline") | ||
| parser.add_argument("--stage", required=True, help="One of the stages [all, dataset, workload, client, analysis]") | ||
| parser = argparse.ArgumentParser(description="Run benchmark pipeline", add_help=True, formatter_class=argparse.RawTextHelpFormatter) | ||
| parser.add_argument("--stage", required=True, help="Specify the benchmark stage to run. Possible stages:\n- all: Run all stages (dataset, workload, client, analysis)\n- dataset: Generate the dataset\n- workload: Generate the workload\n- client: Run the client to dispatch workload\n- analysis: Analyze the trace output") |

While the detailed help message is a great improvement, you can make this more robust by using the choices parameter in add_argument.
This will provide automatic validation for the --stage argument, ensuring only valid stages are accepted. argparse will also generate a helpful error message if an invalid choice is provided.
This makes the manual validation in the run method (lines 278-281) redundant.
Using choices would also prevent passing an empty string ("") as a stage, which is currently an undocumented alias for all.
| parser.add_argument("--stage", required=True, help="Specify the benchmark stage to run. Possible stages:\n- all: Run all stages (dataset, workload, client, analysis)\n- dataset: Generate the dataset\n- workload: Generate the workload\n- client: Run the client to dispatch workload\n- analysis: Analyze the trace output") | |
| parser.add_argument("--stage", required=True, choices=['all', 'dataset', 'workload', 'client', 'analysis'], help="Specify the benchmark stage to run. Possible stages:\n- all: Run all stages (dataset, workload, client, analysis)\n- dataset: Generate the dataset\n- workload: Generate the workload\n- client: Run the client to dispatch workload\n- analysis: Analyze the trace output") |
