Ah. Well, that would do it. :-)

Hm. We should be. Here's the hwloc plugin code for setting CPU affinity (it's
static because it's invoked by function pointer):
static int module_set(opal_paffinity_base_cpu_set_t mask)
{
int i, ret = OPAL_SUCCESS;
hwloc_cpuset_t set;
hwloc_topology_t *t = &mca_paffinity_hwloc_compo
I see this in the solaris binding core:
if (hwloc_cpuset_weight(hwloc_set) != 1) {
errno = EXDEV;
return -1;
}
OMPI doesn't get this error ?
