you misunderstood LarryFinger’s answer…
see, you asked if openSUSE supports SMT, his answer was that ALL Linux
distributions support SMT, not just openSUSE…

i respectfully suggest that the potential savings of two seconds in
boot time is not worth taking the chance you will hose your system
trying to find and change that line in /etc/init.d/rc…for one thing
those instructions were written for a Ubuntu user and openSUSE’s rc
layout is some different…
and, i don’t easily find where that line exists…

i guess you misunderstood that author (or that author is misstaken),
the ability to use multiple processors is built into and available in
all modern Linux kernels…and, has been for some years…you don’t
have to do anything to “turn it on”

ok, the instructions on how to change that CONCURRENCY line is not to
“turn on” the ability to use multiple cores in the OS, but rather to
allow the boot process itself use more than one core/thread…
perhaps that is the default in openSUSE since i do not find the
restricting CONCURRENCY=none statement, but we would need a ‘real’
guru to tell us…
