ROOT CAUSE OF ALL FAILURES: patch_ops.sh was replacing qwen3_5.py, _custom_ops.py, model_runner.py, xformers.py, paged_attn.py, prefix_prefill.py, logits_processor.py, sampler.py, arg_utils.py — killing base image's CoreX fused kernels. Evidence from competitor sub168 docker logs (d03 PASS in 2.12s): - 'Using fused CoreX GDN decode operator' (DeltaNet) - 'Using CoreX fused MoE prefill operator: tokens=4096, kernel=expert-grouped-wmma' - 'Using CoreX FA2 packed prefill: B=2 Hq=4 Hkv=1 D=256' - ZERO NaN warnings - Model weights: 17.35GB (full) Our sub509 (d03 FAIL in 49s): - 'NaN in prefill GatedDeltaNet layer 0 (frac=0.9998)' — 99.98% NaN! - 'FusedMoE native kernel failed, falling back to pure PyTorch' - No CoreX FA2 - Model weights: 16.23GB (incomplete — 1.1GB missing) CCCL design principle (dispatch_reduce_deterministic.cuh, transform.cu): Let the framework's policy_selector choose optimal kernel config per hardware — never hand-replace the dispatch layer. Now patch_ops.sh ONLY patches serving layer: - protocol.py, serving_chat.py, api_server.py, chat_utils.py, cli_args.py - qwen3coder_tool_parser.py (tool call XML parsing) - reasoning/ (think tag parsing) - registry.py (register Qwen3_5 model type) - transformers models (qwen3_5 config) Base image compute files PRESERVED: qwen3_5.py, _custom_ops.py, model_runner.py, xformers.py, paged_attn.py, prefix_prefill.py, logits_processor.py, sampler.py, arg_utils.py, sequence.py, scheduler.py

# BI-V100 engine patches for Qwen3.6-35B-A3B (Qwen3_5 architecture)
|
|
#
|
|
# STRATEGY: Only patch serving/protocol layer. NEVER replace core compute
|
|
# files (qwen3_5.py model, _custom_ops.py, model_runner.py, xformers.py,
|
|
# paged_attn.py, prefix_prefill.py, logits_processor.py, sampler.py).
|
|
#
|
|
# The base image has optimized CoreX kernels:
|
|
# - corex_gdn.py — fused GatedDeltaNet (decode + prefill)
|
|
# - corex_moe.py — fused MoE (expert-grouped-wmma)
|
|
# - corex_fa2.py — FlashAttention2 (packed prefill + paged chunked)
|
|
# Replacing model files breaks these kernel paths and causes:
|
|
# - DeltaNet NaN (99.98% of activations) → model output garbage
|
|
# - MoE fallback to pure PyTorch → 10x slower
|
|
# - FA2 → XFormers fallback → slower attention
|
|
#
|
|
# Reference: competitor sub168 uses base image qwen3_5.py + these CoreX
|
|
# kernels and achieves d03_tool_call in 2.12s (vs our sub509's 49s FAIL).
