I had a look at it and not sure if it really makes sense.
In btl_vader_{put,get}.c it would be easy to check for the user
namespace ID of the other process, but the function would then just
return OPAL_ERROR a bit earlier instead of as a result of
process_vm_{read,write}v(). Nothing would really c
Adrian,
An option is to involve the modex.
each task would OPAL_MODEX_SEND() its own namespace ID, and then
OPAL_MODEX_RECV()
the one from its peers and decide whether CMA support can be enabled.
Cheers,
Gilles

If that works, then it might be possible to include the namespace ID in the
job-info provided by PMIx at startup - would have to investigate, so please
confirm that the modex option works first.

I have most of the code ready, but I still have troubles doing
OPAL_MODEX_RECV. I am using the following lines, based on the code from
orte/test/mpi/pmix.c:
OPAL_MODEX_SEND_VALUE(rc, OPAL_PMIX_LOCAL, "user_ns_id", &value, OPAL_INT);
This sets rc to 0. For receiving:
OPAL_MODEX_RECV_VALUE(rc, "us
Just add it to the existing modex.
