I think I can find some spare time this weekend to try to fix code,
rerun my tests
and post results, unless Lei wants to do this - which I don't mind :)

Have in mind that AVX512 there is a different set of instructions from
those on KNC,
so it's better to use some recent compiler. Also Linux kernel must
support avx512,
which you can check via $ cat /proc/cpuinfo | grep -i avx512
There should be avx512f, avx512pf, avx512cd, avx512er extensions.

Thanks,
Lukas
