Hi,

I've been using --map-by socket:PE=N, where N is used to control the number
of cores a proc gets mapped to. Does this also guarantee that a proc is
bound to N cores in the socket? I am asking this because I see some threads
spawned by the process run outside the given N cores in the socket.

Is this expected or I guess I am missing some binding parameter here? Also,
is there some documentation on these different choices? Are the options in
[1] available in current release?
