Release Notes#

This section includes the verl-hardware-plugin release information.

v0.1.0#

  • Overview

    Initial release of verl-hardware-plugin, providing multi-chip hardware platform and engine plugins for verl. The package is jointly developed by the ByteDance verl team and the FlagOS community, and is auto-discovered by verl through the verl.plugins entry-points group.

  • Added Features

    • Hardware platform implementations registered via @PlatformRegistry.register:

      • FlagOS engine platform on cuda (vendor flagos, NVIDIA verified).

      • MetaX platform on cuda (vendor metax).

      • Iluvatar platform on cuda (vendor iluvatar, BI-V150).

      • Cambricon MLU platform on mlu (vendor cambricon).

      • Enflame GCU platform (vendor enflame).

      • Intel XPU platform on xpu (vendor intel).

    • FSDP and Megatron engine variants for each supported device/vendor pair, registered via @EngineRegistry.register.

    • Stage-scoped environment manager (FLEnvManager) for per-stage FlagGems operator allowlists/blocklists and FlagCX communication control.

    • SMI-based hardware detection for CUDA-compatible devices (nvidia-smi, mx-smi) to disambiguate vendors during auto-detection.

    • Dedicated FlagOS engines (FSDPFlagOSEngineWithLMHead/WithValueHead, MegatronFlagOSEngineWithLMHead) that transparently inject FlagGems acceleration.

    • Cambricon CNCL and CNI XL checkpoint engines.

    • Per-platform user guides and the GSM8K GRPO acceptance baseline script.

    • Validated platforms — the end-to-end GRPO run on GSM8K with Qwen3-0.6B has been completed on MetaX and Iluvatar; the remaining platforms ship as reference implementations.

  • Requirements

    • Python >= 3.10

    • verl >= 0.7.0 (plugin registry from verl#6086; Iluvatar uses verl > 0.8.0)
