Description

This PR significantly revamps the README.md to clearly communicate RL-Kernel's core value proposition and technical positioning as an industrial-grade infrastructure project.

The previous documentation was slightly too granular regarding PyTorch autograd behaviors. We have elevated the messaging to focus on our macro-level impact and architectural integration.

Key Changes:

  • Introduced Our Core Philosophy: Replaced the jargon-heavy alignment section with a high-impact philosophy focusing on Operator-Level Train-Inference Consistency and Extreme Memory & Compute Efficiency.
  • Added Global Architecture Diagram: Introduced a comprehensive, multi-layered architecture diagram. It visually clarifies our boundaries: RL-Kernel sits beneath macro orchestration frameworks (vime, slime, verl) and integrates into execution engines via non-intrusive operator hooks.
  • Clarified Engine Ecosystem: Explicitly mapped out our support ecosystem, including Rollout Engines (vLLM, sglang, LMDeploy) and Training Engines (Megatron, DeepSpeed, FSDP).
  • Pre-commit Config Update: Relaxed the check-added-large-files limit to 1MB to safely accommodate the high-resolution architecture diagram without triggering CI failures.

This update ensures that infrastructure engineers and researchers can immediately understand where RL-Kernel fits in their stack and why it is essential for scaling GRPO workloads.

📝 Walkthrough

Walkthrough

README now includes a "Our Core Philosophy" section describing operator-level principles for train-inference numerical consistency via deterministic reduction orders and memory efficiency through specialized fused kernels. Pre-commit configuration updated to exclude all docs/assets files from large-file checks.

Changes

Core Philosophy Documentation

Layer / File(s) Summary
Core Philosophy section
README.md		 New section introducing operator-focused principles on deterministic reduction orders for train-inference numerical consistency and specialized fused kernels for memory/compute efficiency in large GRPO batches.

Pre-commit Configuration

Layer / File(s) Summary
Pre-commit assets exclusion
.pre-commit-config.yaml		 Broadened the check-added-large-files hook excluded path pattern from a specific logo file to all files under docs/assets/.*.

🎯 1 (Trivial) | ⏱️ ~3 minutes

🐰 Philosophy carved with kernels so keen,
Deterministic roads where none have been!
From VRAM saved to consistency gained,
A pre-commit step, and the docs sustained! 🌟

Check name Status Explanation Resolution
Title check ❓ Inconclusive The title '[readme] Update README.md' is vague and non-descriptive, using generic language that doesn't convey the meaningful changes (introducing 'Our Core Philosophy' section with train-inference alignment priority). Use a more descriptive title that highlights the main change, such as '[readme] Introduce Core Philosophy section with train-inference alignment priority' or '[readme] Add operator-focused philosophy and efficiency claims'.

Does the term "domestic accelerator" need to be revised?

I think make sense, maybe we can use : Ascend / Metax / Cambricon, Are these more accurate?
