Follow-up Comment #8:

You are right, also my Octave 5.0.90 installation can be fooled by the
environment variable OMP_NUM_THREADS (see bug #51643).  And I can even turn my
laptop into a supercomputer :D


OMP_NUM_THREADS=3000000 octave --eval 'system ("nproc"); system ("nproc
--all"); nproc' 
3000000
4
ans =  4
