c840c9159f feat: moe_tcu_dispatch.cpp — C++ MoE expert loop via torch::mm (TCU kernel)
torch profiler confirmed: torch.mm launches Gemm_tcu_bi_kernel::gemm_h_h_tcu_25
which is BI-V100 TCU (Tensor Compute Unit) hardware-accelerated GEMM.
0.58ms per call vs our custom kernel 7.7ms — TCU is 13x faster.

Python for-loop overhead measured: 0.892 ms/expert = 7.1 ms for 8 experts.
This C++ dispatch eliminates that overhead while using the same TCU kernel.

Three entry points:
- moe_decode: full MoE forward (FC1 + SiLU*mul + FC2) for decode
- moe_prefill: group-by-expert MoE forward for prefill
- moe_expert_gemm_tcu: raw GEMM loop for benchmarking

a8ca42b59c perf: hgemm_warptiling Config B — beats cublas on MoE-sized GEMM (0.7x)
probe_k10_configs.sh results on BI-V100:
  256x4096 @ 4096x11008:
    cublas:   10.554 ms
    Config B:  7.649 ms (0.7x cublas — FASTER)
    Config A:  2308 ms  (old broken config)

Config B: BM128 BN128 BK16 WM64 WN64 WNITER2 TM8 TN4 NT128
Root cause of Config A slowness: WN=128 WNITER=4 caused
excessive register pressure and smem bank conflicts.

2b12fe687e feat: hgemm_warptiling.cu — siboehm kernel 10 ported to WARPSIZE=64 FP16
1:1 from upstream_ref/sgemm_cuda/10_kernel_warptiling.cuh.
3 changes: WARPSIZE 32→64, float→__half, FP32 accumulator.

Launch config (confirmed by probe_warp64.sh):
  NUM_THREADS=128, 2 warps of 64
  BM=128 BN=128 BK=16 WM=64 WN=128 WNITER=4 TM=4 TN=4
  WMITER=2, WSUBM=32, WSUBN=32, threads_per_warp=64 ✓

09e5261ba6 refactor: hgemm_blocktiling.cu — strict 1:1 from siboehm kernel 6
Only 3 changes from upstream_ref/sgemm_cuda/6_kernel_vectorize.cuh:
1. float → __half for A/B/C data and shared memory
2. float4 vectorized load → 4 scalar half loads (float4 needs 16-byte align)
3. threadResults accumulator stays float (FP32 accumulation)

Everything else identical: same shared mem layout, same indexing,
same A-transpose-while-loading, same thread tile computation.
No WARPSIZE. No cooperative_groups. No cuda::barrier.

ab42fc1fd7 feat: hgemm_blocktiling.cu — FP16 GEMM kernel for MoE expert dispatch on BI-V100
Adapted from siboehm/SGEMM_CUDA kernel 6 (vectorize + A transpose)
and wangzyon/NVIDIA_SGEMM_PRACTICE kernel 6 (mysgemm_v6).

Key design decisions:
- FP16 data with FP32 accumulation (avoid precision loss)
- No WARPSIZE dependency (safe for BI-V100 warp_size=64)
- Boundary checks for non-aligned M/N/K (MoE expert token counts vary)
- BM=128 BN=128 BK=8 TM=8 TN=8 (256 threads, fits BI-V100 128KB smem)
- A transpose in shared memory for coalesced reads

Two entry points:
1. hgemm(A, B) — standalone FP16 GEMM
2. moe_expert_gemm(input, weights, expert_counts) — MoE prefill path
   loops over experts with variable token counts

For decode (M=1), use cublasHgemmStridedBatched (confirmed working).

29ecc2e602 feat: moe_expert_gemm.cpp — C++ loop over experts via ixformer_linear (replaces Python for-loop)
Key difference from the reverted batched approach:
- Does NOT use torch::mm in a C++ loop (that was the reverted commit)
- Uses ixformer_torch_ext::ixformer_linear — the base image's optimized GEMM
- Same kernel the competitor (sub 168) uses via corex_moe.py
- Eliminates Python interpreter + dispatcher overhead per expert
- Links against _ixformer_torch.cpython-310.so (already in base image)

Decode: 1 Python call → 8 C++ ixformer_linear (vs 8 Python F.linear)
Prefill: 1 Python call → 64 C++ ixformer_linear (vs 64 Python F.linear)

06d7713db6 feat: batched MoE expert GEMM — replaces Python for-loop
ixformer probe results:
  ✗ moe_w16a16_group_gemm NOT in ixformer .so
  ✗ CUTLASS grouped GEMM needs cuda/std (variadic function error on corex)
  ✓ ixformer_linear EXISTS (fused matmul)
  ✓ torch.mm works (uses corex cublas)

Solution: moe_batched_gemm.cu
  - C++ loop over experts (eliminates Python overhead)
  - torch::mm for GEMM (corex cublas, not F.linear Python)
  - Fused silu_and_mul CUDA kernel (not PyTorch ops)
  - Weighted scatter-add in C++
  - Skips empty experts (no wasted compute)

Integration in qwen3_5.py:
  _USE_XLLM_MOE_GEMM dispatches to moe_experts_forward()
  Falls back to Python for-loop if not available

a50adefdfc feat: xllm MoE CUDA kernels — fused_topk + compute_index + combine
3 MoE kernel files adapted for corex:
  moe_fused_topk.cu: LOG(FATAL)→TORCH_CHECK, +torch/extension.h
  moe_compute_index.cu: CHECK_LE→TORCH_CHECK, uses cub::BlockScan (corex CUB)
  moe_combine.cu: fixed duplicate include, +torch/extension.h

New pybind binding: xllm_moe_bind.cpp
  → moe_fused_topk(gating, topk, renormalize, bias, scoring_func)
  → moe_compute_index(expert_id, num_experts)
  → moe_combine_result(gemm2, weights, N, topk)

AST verification added for all 3 functions

norm.cu compiled successfully on BI-V100 (only warning: fp8 __host__ attr).
Failed at import because no PYBIND11_MODULE — now fixed.

New bindings/ directory with 4 binding files:
  xllm_norm_bind.cpp      → rms_norm, fused_add_rms_norm
  xllm_activation_bind.cpp → silu_and_mul, gelu_and_mul, act_and_mul
  xllm_rope_bind.cpp       → rotary_embedding
  xllm_cache_bind.cpp      → reshape_paged_cache, block_copy

415fff85f1 fix: add DISPATCH_FLOATING_TYPES macro to device_utils.cuh
DISPATCH_FLOATING_TYPES was defined in xllm/core/kernels/cuda/utils.h
which was pulled in via cuda_ops_api.h → utils.h.
Since cuda_ops_api.h was removed (glog dependency), the macro was missing.

Now defined in device_utils.cuh with include guard, available to all kernel files:
  norm.cu, activation.cu, rope.cu, block_copy.cu, reshape_paged_cache.cu

0359103b9b fix: remove glog/cuda_ops_api.h dependency from all xllm CUDA kernels
cuda_ops_api.h includes glog/logging.h and ATen/DynamicLibrary.h
which are not available in corex standalone compilation.

All kernel .cu files only need device_utils.cuh (provides namespace,
XLLM_KERNEL_ATTR macro, CUB includes, type helpers).

Fixed files:
  norm.cu, activation.cu, rope.cu, block_copy.cu, reshape_paged_cache.cu
  moe/moe_combine.cu, moe/moe_compute_index.cu, moe/moe_fused_topk.cu

51cb90b9ab fix: adapt xllm norm.cu for corex CUB (CUDA 10.2)
Key change: replace CCCL 3.6 types with corex CUB equivalents
  - cuda::std::plus<> → cub::Sum
  - cuda::maximum<>  → cub::Max
  - Remove #include <cuda/std/functional>

Test results from real machine (3/4 passed):
  ✓ __shfl_down_sync works on ivcore10
  ✓ manual SMEM+shuffle block reduce works
  ✓ corex CUB cub::BlockReduce<float,256> compiles and runs correctly (32640)
  ✗ CCCL 3.6 variadic function issue — corex clang rejects device variadic

Confirmed: use /usr/local/corex/include/cub/ for all kernel code
           cccl_upstream is reference only, NOT compilable on corex

  - 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

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):

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)

051b02d3cd feat: ix_moe_bridge + ix_attn_bridge — dlopen bridges for full ixformer::infer API
Bridge architecture (from xllm/core/kernels/ilu/ixformer.h):

ix_moe_bridge.so (MoE 7-step fused pipeline):
  - topk_softmax → moe_compute_token_index_api → moe_expand_input
  - moe_w16a16_group_gemm (x2) → silu_and_mul → moe_output_reduce_sum
  - fused_moe_forward(): replaces entire Python expert loop
  - Fix: group_gemm format NT→TN (match xllm trans_b=true)

ix_attn_bridge.so (attention + linear):
  - ixinfer_flash_attn_unpad_with_block_tables (fused prefill)
  - xllm_paged_attention (fused paged decode)
  - ixformer_linear (matmul + activation)
  - residual_rms_norm (fused residual + norm)

Integration:
  - ix_fused_moe.py: Python loader (prebuilt .so → JIT → unavailable)
  - qwen3_5.py: Tier 0 dispatch in _pure_pytorch_experts()
  - patch_ops.sh: deploys ix_fused_moe.py + all prebuilt/*.so

0b0c47fddd fix(critical): fold max_completion_tokens + max_num_seqs=2 + max_model_len=80000 + xllm_latest layer import
Sub 655 root causes (confirmed from log analysis):
1. protocol.py: max_completion_tokens never folded into max_tokens
   → 162/881 replay requests rejected 400 (extra_forbidden)
2. max_num_seqs=1 → t2_n_2 test fails (needs n=2)
3. max_model_len=131072 → OOM crash at 62% replay, opencompass all 0

Fixes:
- protocol.py: model_validator fold_max_completion_tokens
- yaml: max_num_seqs=2, max_model_len=80000, PYTORCH_CUDA_ALLOC_CONF
- topk_softmax stays =0 (corex CUB BlockReduce incompatible on BI-V100)

xllm_latest import to ex_engine/:
- npu_torch layers: GDN(1164L), Qwen3.5 GDN, attention, fused_moe
- cuda/moe kernels: topk_softmax_kernels.cuh, moe_combine, moe_compute_index

cf1b701afe fix(build): 回退qwen3_6_scripts+ex_engine到26e6cb40(能得分版本)
唯一改动: computility-run.yaml max_model_len 80000→100000

26e6cb40是Sub520能在竞赛平台docker build成功并得分的版本
之后所有commit都导致docker build失败
根因: 新增的65个文件(vendor_overrides/prebuilt/*.so/wheels等)
可能触发了竞赛平台docker build的某个限制

本次回退:
- qwen3_6_scripts/: 110→45文件(删掉65个新增文件)
- ex_engine/: 恢复到26e6cb40完全一致
- Dockerfile: 恢复5个RUN步骤结构(已验证能build)
- computility-run.yaml: max_model_len=100000(避免replay 400拒绝)

6425a96728 fix(runtime): bridge加载失败安全降级到Tier1(ixformer.functions)
根因:ixformer.h声明的是ixformer::infer::*命名空间,但base image
实际导出的是ixformer_torch_ext::*(in _ixformer_torch.so)和
ixformer::functions::*(in libixformer.so)。命名空间不匹配导致
bridge .so虽然编译成功但import时undefined symbol。

当前方案:bridge加载失败时安全降级到Tier1(ixformer.functions),
这是base image的Python binding,底层调用同样的CUDA kernel,性能一致。
Tier1已有silu_and_mul/rms_norm/rotary_embedding/paged_attention等。

后续迭代:重写ixformer.h用正确的ixformer_torch_ext namespace。

ix_moe_bridge.so编译成功但加载时undefined symbol: silu_and_mul
原因:libixformer.so的符号在link time不可用
修复:-Wl,--unresolved-symbols=ignore-in-shared-libs
(和ix_unified_bridge.sh用的同一个方案)

运行时符号解析:ix_unified.py已有RTLD_GLOBAL preload逻辑

新增probe_all_so.py:在真机上探测12个.so的全部导出方法

97d9842180 fix(CRITICAL): bridge build delayed binding + Docker tolerance + improved preload
build_unified_bridge.sh:
  - set -euo → set -eo (avoid unbound var failures)
  - Drop -ltorch_cuda -lc10_cuda (unavailable at Docker build time)
  - Add -Wl,--unresolved-symbols=ignore-in-shared-libs
    ixformer::infer symbols resolved at runtime via RTLD_GLOBAL preload

Dockerfile Step 6:
  - Wrap in (... || echo non-fatal) so Docker build continues if bridge fails

ix_unified.py:
  - 3-phase preload: lib*.so → _ixformer_torch*.so → remaining .so
  - All loaded with ctypes.RTLD_GLOBAL so symbols visible to bridge
  - Added /workspace and /home/dylan search paths

Verified on real machine: bridge compiles (272K), undefined symbols expected
until ixformer .so preloaded at runtime by ix_unified.py

ed8bdf8714 fix(CRITICAL): merge 26e6cb40 build pipeline + HEAD features — fix docker build
Key changes:
1. Dockerfile: restore ex_engine COPY + build steps from 26e6cb40 (working),
   add vendor_overrides staging, add ix_unified_bridge build step
2. computility-run.yaml: restore Sub168 proven params (max-model-len=80000,
   gpu-util=0.95, max-num-seqs=2, enforce-eager, dtype=half) + corex env vars
3. patch_ops.sh: make vendor_overrides missing non-fatal (skip instead of exit 2)
4. New: corex_so_loader.py — unified loader for 12 prebuilt .so
5. New: moe_fused_dispatch.py — 3-tier MoE dispatch (CCCL policy_selector)

Docker build was failing because:
- HEAD removed ex_engine COPY and all build steps
- patch_ops.sh exit 2 on missing vendor_overrides killed build
- computility-run.yaml had max-model-len=262144 causing OOM

26e6cb40 scored on competition platform. This commit restores that build
pipeline while adding the new HEAD features (prebuilt .so, vllm_overrides,
corex dispatch env vars).
