Ouch - will have to fix that.

I'll have to let Jeff answer that one, but I should think not as it is dynamically loaded. For now, you can turn that warning off by adding -mca hwloc_base_mem_bind_failure_action silent Jeff is responsible for the length of that param :-) > > Z Koza > > > > 2012/9/1 Ralph Castain <r...@open-mpi.org> > You are using cmd line options that no longer exist in the 1.9 release - look > at "mpirun -h" for the current list of options. > > FWIW: in your example, the correct cmd line would be: > > mpirun -np 2 --bind-to core -map-by core --report-bindings uptime > > Note the space in "--bind-to core" and the "-map-by" option syntax.
