375d439abb feat: 新增 H20 支持、优化算力测试精度并修复多项稳定性问题
- gpu_specs: 新增 H20/H20-3e (中国合规版 H200) 规格定义,并修复
  GPU 名称匹配顺序,避免 "H200" 被 "H20" 子串误匹配
- benchmark(compute): 引入 L2 cache 规避的 matrix pool 轮换 +
  可选 torch.compile(max-autotune),FP8 增加 _scaled_mm 探测,
  显著提升 FP16/BF16/FP8 实测吞吐准确性
- benchmark(memory): nvbandwidth 增加 --disableAffinity 规避
  fabricmanager NVML 不兼容;全 0 结果时自动回退到 PyTorch;
  D2D 平均值排除对角线零值
- nccl: 各通信操作 (AllReduce/AllToAll/Broadcast 等) 使用独立
  带宽阈值比例,避免 AllToAll 误报 WARN
- rdma: 仅按 link_layer=InfiniBand 过滤端口,无 IB 硬件或全 DOWN
  时直接 SKIP 而非报错
- stress: 计算矩阵尺寸封顶 4096,并改为先并发派发再统一同步,
  修复 8 卡串行执行导致 duration 严重超时的问题
- report: 兼容 RDMA SKIP 状态与 PyTorch 回退场景的 Memory 判定,
  避免回退结果被误判为 FAIL
- config: 新增 benchmark.compute.use_compile 开关

fefef8e03b refactor: remove hardcoding, fix AMP bug, unify English output
- Fix AMP autocast: bf16 now uses torch.amp.autocast (was skipped)
- Fix NCCL threshold: unknown GPU gets 10 GB/s floor instead of 0
- Fix PCIe health check: use specs-driven pcie_gen, not hardcoded Gen4
- Remove hardcoded GPU lists: dynamic banner, CLI choices, version
- Unknown GPU efficiency displays N/A instead of 0%
- Unify all console output to English (stress_test, gpu_tester)
- Use importlib.metadata for runtime version resolution
- Remove dir="/tmp" from tempfile (use system default)

f2158f6cd3 fix: resolve stress OOM, D2D efficiency calculation, NCCL execution failures
Key changes:
- stress_test: use torch.cuda.mem_get_info() for free memory instead of total,
  allocate 40% to avoid OOM when other processes occupy GPU memory
- benchmark: fix D2D efficiency by comparing to NVLink per-direction bandwidth
  (not HBM), add H2D/D2H efficiency against PCIe peak
- nccl_test: implement direct binary → mpirun → torchrun fallback chain,
  fix min_bw None bug when YAML value is empty
- report: update memory section to use per-metric peak fields
- install_deps.sh: add NCCL compatibility detection, enhance CUDA version
  detection with CUDA_HOME/standard paths, improve _map_cuda_tag logging
- gpu_info: parse CUDA version from nvidia-smi header (query field removed
  in newer drivers)
- health_check: parse throttle_reasons bitmask properly, ignore gpu_idle bit
- gpu_tester: fix suite summary to exclude metadata keys from pass count

3e967dd34a feat: add Ampere (A100/A800) support and generalize project naming
- Expand GPU specs database to include A100/A800 with Ampere architecture parameters
- Rename h200_tester.py to gpu_tester.py for architecture-neutral branding
- Add driver/CUDA compatibility validation per GPU generation
- Enhance report module with HTML and Markdown output formats
- Improve nvbandwidth binary discovery (system paths, DCGM locations)
- Add pyproject.toml with uv for dependency management
- Update install_deps.sh, configs, and README for multi-architecture support
