EX Engine 002f9879b2 ref(upstream): FULL TREE — Deep-Spark xllm (1470) + ds_vllm csrc/models (703)
Replaces cherry-picked upstream_ref with complete source trees.

xllm/ — Iluvatar official C++ inference engine (15MB, 1470 files)
  Complete: kernels → layers → models → runtime → scheduler → api
  Excluded: .git, binary images, third_party submodule checkouts

ds_vllm/ — Iluvatar official vllm fork (8MB, 703 files)
  Included: csrc/ (ALL CUDA kernels), fused_moe/, qwen3_5 model, _custom_ops
  Excluded: tests, benchmarks, docs, examples (not needed for reference)

Critical call chains now fully traceable:
  MoE: moe_topk_softmax_kernels.cuh → ixformer.h → fused_moe.cpp → layer
  GDN: qwen3_gated_delta_net_base.cpp → qwen3_5_gated_delta_net.cpp
  Attention: ixformer.h → xllm_paged_attention → attention.cpp

What's here

xllm/ (complete source minus git/binaries/submodules)

天数智芯官方下一代推理引擎C++ 原生,多平台(CUDA/ILU/MLU/NPU)。 包含 kernels → layers → models → runtime → scheduler → api_service 完整栈。

Key subtrees:

  • xllm/core/kernels/ilu/ — ixformer API wrappers (ixformer.h是金矿)
  • xllm/core/kernels/cuda/moe/ — MoE CUDA kernels (topk_softmax, fused_topk)
  • xllm/core/kernels/cuda/ — activation, norm, rope, attention CUDA kernels
  • xllm/core/layers/ilu/ — Iluvatar FusedMoE完整pipeline
  • xllm/core/layers/npu_torch/ — GatedDeltaNet C++ implementation
  • xllm/models/llm/qwen3_5.h — Qwen3.5 model definition
  • xllm/compiler/tilelang/ — GDN kernel code generation

ds_vllm/ (csrc + model layers + fused_moe)

天数智芯官方vllm forkPython + CUDA torch extension。

  • csrc/ — ALL CUDA source (attention, moe, quantization, cache)
  • csrc/libtorch_stable/moe/topk_softmax_kernels.cu — vllm topk_softmax
  • vllm/_custom_ops.py — Python → torch.ops._moe_C bridge
  • vllm/model_executor/models/qwen3_5.py — ds_vllm的qwen3_5实现
  • vllm/model_executor/layers/fused_moe/ — vllm FusedMoE Python layer
