Hi Roland,

I can't find this message in the Open MPI source code. Could it be hwloc ? Some other library you are using ?

Hi,

OpenMPI 2.0.2 built with cuda support brings up lots of warnings like

NVIDIA: no NVIDIA devices found

when running on HW without Nvidia devices. Is there a way to suppress
these warnings? It would be quite a hassle to maintain different OpenMPI
builds on clusters with just some GPU machines.
