Follow-up Comment #13, bug #61246 (project octave):

I tested another computer by Dell

  Model: Dell Precision 5820
  Specs: Intel(R) Xeon(R) W-2133 CPU @ 3.60GHz   3.60 GHz

1. Version 6.3.0

   OpenBLAS      + Hyperthreading on:   wrong  results
   OpenBLAS      + Hyperthreading off:  wrong  results
   ReferenceBLAS + Hyperthreading off: correct results

2. Version 6.3.2 (octave-2021-10-02-00-22-w64-installer)
   OpenBLAS      + Hyperthreading off: correct results
   ReferenceBLAS + Hyperthreading off: correct results

Conclusions
   Hyperthreading: no effects
   Version 6.3.0 vs. 6.3.1: effective
