Show which CPU is executing a thread?

[nocturnal]

I've been searching the web, all i want is to show which CPU is currently
executing a certain thread. Is this info available to me in user space?
Which manuals should i read to do this?

I know Solaris has something about lwp that can show the last CPU used, i
think. I would be happy if FreeBSD had something similar so it doesn't have
to be very live or accurate.

Thank you in advance for any info or hints.
