Can you describe how you're verifying that the process is actually
bound?
May I ask I question about the code, which I scanned.
I see in ompi/runtime/ompi_mpi_params.c you do a:
mca_base_param_reg_int_name("mpi", "paffinity_alone",
"If nonzero, assume that this job
is the only (set of) process(es) r
unning on each node and bind processes to processors, starting with
processor ID 0",
false, false,
(int) ompi_mpi_paffinity_alone,
&value);
ompi_mpi_paffinity_alone = OPAL_INT_TO_BOOL(value);
You're right that we're not checking the return value here, which is
bad. However, this is a pretty stable portion of the code -- I would
be surprised if it is failing.
Have you stepped through this with a debugger to verify if it is
actually failing or not?
