- Replace diag level 1-4 dropdown with Validate/Stress radio buttons - Validate: dcgmi L2, 60s CPU, 256MB/1p memtester, SMART short - Stress: dcgmi L3 + targeted_stress in Run All, 30min CPU, 1GB/3p memtester, SMART long/NVMe extended - Parallel GPU mode: spawn single task for all GPUs instead of splitting per model - Benchmark table: per-GPU columns for sequential runs, server-wide column for parallel - Benchmark report converted to Markdown with server model, GPU model, version in header; only steady-state charts - Fix IPMI power parsing in benchmark (was looking for 'Current Power', correct field is 'Instantaneous power reading') Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
