/**
* Qwen3.5 Full-GPU Challenge — VRAM 극한 최적화 벤치마크
* =====================================================
* 목표: Qwen3.5-35B-A3B를 24GB 듀얼 3060에 100% GPU로 올리기
*
* 테스트 모델:
* 1. UD-IQ4_NL (16.6 GB) — 확실히 올라감, 기준선
* 2. MXFP4_MOE (20.1 GB) — 도전! VRAM 극한 최적화
* 3. Q4_K_M (20.5 GB) — 대조군 (n-cpu-moe=5)
*
* VRAM 절감 전략:
* A. 배치 최소화: -ub 64 -b 256 (computation buffer 축소)
* B. split-mode row (GPU간 더 균등한 분배)
* C. tensor-split 수동 밸런싱
* D. no-mmap (메모리 관리 최적화)
* E. defrag-thold (KV 캐시 파편화 방지)
*
* Run: node scripts/qwen_fullgpu_challenge.mjs
