Sorry; I was out for the holiday last week, but a clarification:
libnuma's man page says that numa_run_on_node*() binds a "thread", but
it really should say "process". I looked at the code, and they're
simply implementing a wrapper around sched_setaffinity(), which is a
per-process binding. Not a per-thread binding.

if you look at recent versions of libnuma, there are two functions
called numa_run_on_node() and numa_run_on_node_mask(), which allow
thread-based assignments to CPUs....
