Same error message, unfortunately. And no, I’m not setting a global binding 
policy, as far as I can tell:

env | grep OMPI_MCA
OMPI_MCA_hwloc_base_report_bindings=1
[compute-7-6:15083] SETTING BINDING TO CORE
--------------------------------------------------------------------------
A request for multiple cpus-per-proc was given, but a directive
was also give to map to an object level that cannot support that
directive.

Please specify a mapping level that has more than one cpu, or
else let us define a default mapping that will allow multiple
cpus-per-proc.
