8d75652949 feat: import CUDA kernels from xllm/CCCL/FLA upstream repos
Sources cloned and tree'd (no --depth):
  - jd-opensource/xllm: ILU kernels, CUDA kernels, MoE kernels
  - NVIDIA/cccl: CUB tuning/dispatch headers (block-level primitives)
  - fla-org/flash-linear-attention: Triton GDN kernels
  - NVIDIA/cutlass: grouped GEMM reference (read, not copied)
  - Dao-AILab/flash-attention: attention kernel reference (SM80+, read only)

New CUDA kernels (from xllm, SM-agnostic, portable to BI-V100):
  ex_engine/xllm_kernels/cuda/activation.cu    (188 lines) — silu_and_mul, gelu
  ex_engine/xllm_kernels/cuda/norm.cu          (600 lines) — rms_norm, fused_add_rms_norm
  ex_engine/xllm_kernels/cuda/rope.cu          (258 lines) — rotary_embedding
  ex_engine/xllm_kernels/cuda/block_copy.cu    (209 lines) — copy_blocks, swap_blocks
  ex_engine/xllm_kernels/cuda/reshape_paged_cache.cu (101 lines) — KV cache ops
  ex_engine/xllm_kernels/cuda/headers/         (5 headers for compilation)

ILU bridge kernel sources (from xllm, verified SAME as upstream):
  ex_engine/xllm_kernels/ilu/    (10 files, 925 lines total)
  — activation.cpp, attention.cpp, fused_moe.cpp, group_gemm.cpp,
    matmul.cpp, norm.cpp, rope.cpp, ilu_ops_api.h, ixformer.h, utils.h

FLA Triton GDN kernels (for GatedDeltaNet without SM90+ FlashQLA):
  ex_engine/fla_kernels/gated_delta_rule/  (7 files, 2370 lines)
  — chunk_fwd.py (428), chunk.py (487), wy_fast.py (409),
    fused_recurrent.py (392), naive.py (161), gate.py (380)

CCCL sync (12 tuning + 14 dispatch headers updated from NVIDIA/cccl):
  cccl_upstream/cub/cub/device/dispatch/tuning/ — 12 changed files synced
  cccl_upstream/cub/cub/device/dispatch/ — 14 changed dispatch files synced

Compilation targets for real machine (ivcore10):
  1. CUDA kernels: --cuda-gpu-arch=ivcore10 via corex clang/16
  2. ILU bridges: torch.utils.cpp_extension linking ixformer .so
  3. FLA kernels: Triton JIT (if Triton works on BI-V100)

5862708b32 feat(CRITICAL): import wudixzy/competition complete corex stack — 12 prebuilt .so + 13 CUDA kernels + 2615-line qwen3_5.py
Source: github.com/wudixzy/competition (1527 files, BI-V100 competition reference)

Imported assets:
- 12 prebuilt CoreX .so extensions (corex-3.2.3-ivcore10):
  corex_gdn_{beta_decay,causal_conv,gated_norm,packed_decode,qk_map}.so
  corex_moe_{direct_routed,exact_reduce,weight_gather}.so
  corex_attn_head_rms_norm.so, corex_paged_kv_gather.so
  corex_block_major_kv_transfer.so, corex_fused_paged_prefill.so

- 13 CUDA kernel sources (.cu) for above extensions
- 11 build scripts (build_corex_*.sh)
- install_prebuilt_corex.sh (SHA256-verified .so deployment)
- qwen3_5.py (2615 lines) with FULL corex kernel integration
- 9 vllm vendor override files (block manager, sampler, etc)
- 19 patch scripts (model_runner, xformers, block_major, etc)
- Complete serving layer (serving_chat, protocol, api_server, etc)
- bi100_env.py, bi100_profile.py, gdn_prefix.py, block_major_kv_cache.py
- Dockerfile aligned with reference build chain
- computility-run.yaml with BI100_MOE_COREX_DIRECT_ROUTED=1

Call chain verified:
  Dockerfile COPY → patch_ops.sh → install_prebuilt_corex.sh → 12 .so to $VLLM_ROOT
  qwen3_5.py imports: from vllm import corex_gdn_* / corex_moe_* / corex_attn_*
