If we use carto to limit hcas/ports are used on a given host on a

either uint8_ts, or maybe even a variable length bitmap.
So you propose that each proc will send info (using node_send())
about every
hca/proc on a host even about those that are excluded from use by
the proc
just in case? And then each proc will have to send additional info
(using
proc_send() this time) to indicate what hcas/ports it is actually
using?
No, I think it would be fine to only send the output after
btl_openib_if_in|exclude is applied. Perhaps we need an MCA param to
say "always send everything" in the case that someone applies a non-
homogeneous if_in|exclude set of values...?
When is carto stuff applied? Is that what you're really asking about?
