Hardware Info
Theoretical Peak Performance
CPU (FP64)
FLOPS = cores × freq(GHz) × 2(FMA) × SIMD_width
SIMD: SSE=2, AVX/AVX2=4, AVX-512=8 (FP64)
GPU (FP64)
FLOPS = SMs × FP64_cores_per_SM × freq × 2(FMA)
Multi-GPU: multiply by GPU count
Memory Bandwidth
BW = channels × bus_width(bit)/8 × freq(MT/s)
Requirements
- SE creates
hardware_info.md at project start with actual commands on compute nodes
- Theoretical peak must be calculated with formula shown
- At least one PG verifies via batch job
- B/F ratio (Byte/FLOP) must be noted for memory-bound vs compute-bound classification
