[TriLUG] The Linux kernel has been accidentally hard-coded to a maximum of 8 cores for the past 15 years and nobody noticed

I'm not sure how that conclusion can be reached in light of the fact
that I have been using 6, 8, 12, 14, and 16 cores (X2 for CPUs with HT)
for years. According to all the tools like top, htop, atop, glances, and
more, all of those cores and CPUs are in full use. Also the results my
systems show on the stats page of World Community Grid shows that all my
computers are performing calculations for the full number of cores and
CPUs present. So my 16-core, 32-CPU i9 host generates 32 days of
processing for each 24-hour day it runs.

However it was an interesting read. ;-)
