Something I should have mentioned. The paffinity_base_service.c file
is solely used by the rank_file syntax. It has nothing to do with
setting mpi_paffinity_alone and letting OMPI self-determine the
process-to-core binding.
You want to dig into the linux module code that calls down into the
plpa. The same mca param should give you messages from the module, and
-might- give you messages from inside plpa (not sure of the latter).

I've been trying to track back from the linux
paffinity module to find some useful debugging
info I can get my teeth into and I can see that
the file:
opal/mca/paffinity/base/paffinity_base_service.c
seems to have lots of useful debugging message that
should output what processes are getting bound where,
but they are often conditional on the diag_requested
variable. It seems that diag_requested is set based
on this logic:
if (4 < opal_output_get_verbosity(opal_paffinity_base_output)) {
diag_requested = true;
} else {
diag_requested = false;
}
But I can't see what I have to set to make those messages
appear! I've been through the output of ompi_info -a in case
there was something listed there but nothing leapt out at me.
Any clues please ?
cheers,
Chris
