Introduction

Interpretation of the core energy efficiency indicator system

Performance indicators	Calculation method	Measurement requirements
HPCEE	Measured FLOPS/system energy consumption	≥5 consecutive tests
FLOPS	M/(t×10^9)	Triangular system solution time ≥30min

Analysis of key test technologies

Compute nodes use matrix blocking technology in the LU decomposition stage:

Matrix initialization formula: A = LU (dimension N×N)
Key calculation steps:
A₂₂ - L₂₁U₁₂ = L₂₂U₂₂
Accelerator card nodes must meet double-precision floating-point calculations

Energy efficiency classification and acceptance standards

Energy efficiency rating	HPCEE value range	Power consumption test error
Special grade	≥5,000 MFLOPS/kW	≤±2.5%
Level 1	2,000-4,999 MFLOPS/kW	≤±3%
Level 2	1,000-1,999 MFLOPS/kW	≤±5%

Technical Points for Implementation of Standards

Environmental requirements guarantee:
- Temperature fluctuation <±0.5℃/h
- UPS power supply ripple factor <5%
- See Chapter 6 Cooling subsystem adaptation specification
Test tool verification:
- Electricity monitoring equipment must achieve 0.5S-level accuracy
- Lindpack test procedures must pass N≥1e5 large matrix verification

Inspiration for industry development

This standard unified for the first time:

Energy efficiency conversion method for heterogeneous computing nodes
Storage subsystem energy consumption calculation method

Typical application:
An AI supercomputing project passed the standard test:
The measured computing efficiency reached 73.6%, saving>820,000kWh of electricity per year.
