14 definitions. Thus, the way to read up on Linux topology on x86 is to start
113 A thread is a single scheduling unit. It's the equivalent to a logical Linux
152   The alternative Linux CPU enumeration depends on how the BIOS enumerates the
154   That has the "advantage" that the logical Linux CPU numbers of threads 0 stay
