MLCFlow: Simplifying MLPerf Automations
MLCFlow is a versatile CLI and Python interface developed by MLCommons in collaboration with a dedicated team of volunteers (see Contributors). It serves as a streamlined replacement for the CMind tool, designed to drive the automation workflows of MLPerf benchmarks more efficiently.
The concept behind CMind originated from Grigori Fursin, while the MLPerf Automations project was created by Grigori Fursin and Arjun Suresh, whose collective contributions laid the foundation for modernizing MLPerf benchmarking tools.
On February 9, 2025, MLCFlow is releasing its first stable version, 1.0.0. This milestone was led by Arjun Suresh and Anandhu Sooraj, with support from the MLCFlow community.
Building upon the core idea of CMind—wrapping native scripts with Python wrappers and YAML metadata—MLCFlow focuses exclusively on key automation components: Scripts, along with its complementary modules: Cache, Docker, and Experiments. This targeted design simplifies both implementation and interface, enabling a more user-friendly experience.
MLCFlow is now fully equipped for workflow development, with complete support for all previously used CM scripts in MLPerf inference automation. If you're interested in discussions, join the MLCommons Benchmark Infra Discord channel, and check out the latest progress in Issues.
The MLC Command-Line Interface (CLI) enables users to perform actions on specified targets using a simple syntax:
mlc <action><target> [options]<action>: The operation to be performed.<target>: The object on which the action is executed.[options]: Additional parameters passed to the action.
- Actions related to repositories, such as cloning or updating.
- Manage or execute automation scripts.
- Handle cached data, including cleanup or inspection.
Each target has its own set of specific actions to tailor automation workflows as specified below.
| Target | Action |
|---|---|
| script | run, find/search, rm, mv, cp, add, test, docker, show |
| cache | find/search, rm, show |
| repo | pull, search, rm, list, find/search |
MLC started with a compatibility layer where by it supported MLCommons CM automations - Script, Cache and Experiment. Now, MLCFLow has just the Script Automation which is an extension of the Script Automation from CM but with a cleaner integration of Cache Automation and Docker and Test extensions. The old CM scripts are now updated with the latest MLCFlow scripts in the MLPerf Automations repository.
