Thanks for the tip, tuning the sched_mc_power_savings setting helped! The
original value of it was 0, but after setting it to 1, the two
cpu-intensive processes got scheduled to different CPU cores, as expected.

Setting it back to 0 casused the two cpu-intensive processes to run on
the same CPU again. So I guess I will just set it to 1 after booting the
system.

But just out of curiousity, this strange behaviour of the scheduler
without poking sched_mc_power_savings is a bug or a feature?

Regards,
Marton
