Well, I think it would be useful if we can look at /proc/cpuinfo and
get a mapping from Linux CPU number to "topological address" (socket
id, core id, thread id). With that plus taskset, it would be very
easy to run a test with, for example, two processes pinned to the two
threads on the same core or pinned to separate cores, etc.

What is it being used for?
