Claude 36676f2d1b data: complete SGEMM upstream from 3 repos (siboehm+wangzyon+edtallison) + xllm fused_qknorm_rope + xattention kernels
SGEMM repos (upstream_ref/sgemm_cuda/, 41 files):
  siboehm/SGEMM_CUDA: kernel 1-12, runner, CMake, cuBLAS benchmark
  wangzyon/NVIDIA_SGEMM_PRACTICE: kernel 1-7 (Chinese comments), utils
  edtallison/sgemm-cuda: kernel 01-09 (learning notes), Makefile

xllm kernels (ex_engine/xllm_kernels/cuda/):
  fused_qknorm_rope.cu + bind — saves 128 kernel launches/fwd
  xattention/ — 6 files from upstream xllm
  headers: corex_compat_utils.h, topk_last_dim.cuh
  ilu/CMakeLists.txt

# build_xllm_kernels.sh — Compile xllm CUDA kernels into .so for BI-V100
#
# Architecture (CCCL compile pattern):
# CCCL: CMakePresets.json → cmake --preset cub-cpp20 → ninja → .so
# EX: torch.utils.cpp_extension → clang --cuda-gpu-arch=ivcore10 → .so
#
# Usage:
# bash ex_engine/build_xllm_kernels.sh [--output-dir /path/to/output]
#
# Prerequisites:
# - BI-V100 machine with corex SDK
# - PyTorch with CUDA support
# - corex clang/16 compiler
#
# Outputs:
# xllm_fused_qknorm_rope.so — Fused QK-Norm + RoPE (saves 128 kernel launches/fwd)
