01 / Question & hypothesis

What was tested?

P8 retains its throughput gain while meeting paired energy/thermal noninferiority.

02 / Scientific basis

Why the test is meaningful

Even an independently replicated scheduler needs energy confirmation; an odd number of order cycles can leave residual external-position confounding.

Eratio=(J/hash)_P8/(J/hash)_P1noninferiority requires header consistency and bounded CIthree cycles create 2:1 external-order imbalance

03 / Method

How it was tested

Measure four unseen headers, three ABBA+BAAB cycles per header, 96 processes and direct 100-Hz NVML telemetry.

04 / Observed result

What happened

Process speedup1.003261×
Energy ratio0.995164
Energy verdictINCONCLUSIVE

Speed persisted at 1.003089× kernel and 1.003261× process. Aggregate energy ratio was 0.995164, but only 2/4 headers passed and paired 95% interval was 0.984555–1.005888. Header parity perfectly tracked the residual order imbalance.

05 / Validation

Exactness and statistical controls

The energy endpoint is kept inconclusive rather than averaged into a favorable claim. Exactness, depth and thermal checks passed.

06 / Interpretation

What the result means

P8 throughput is confirmed, while energy remains unresolved until four balanced cycles give each external order equal representation.

Limitations

  • Three cycles are externally unbalanced.
  • Energy is neither confirmed nor rejected.
  • Maximum observed temperature was 65°C.
07 / Reproduction

Evidence trail

Repeat with four cycles per header, two of each external sequence, preserving sealed P1/P8 binaries.
