Hi Siegmar,

This has been fixed in the driver some time ago. Getting the latest
driver should solve your problem.

You can check the driver version with nvidia-smi, then go to
http://www.nvidia.com/Download/index.aspx to get the latest.

Hi,
I have installed openmpi-master-201708110239-03544d7 and openmpi-2.1.2rc1
on my "SUSE Linux Enterprise Server 12.2 (x86_64)" with Sun C 5.15 and
gcc-5.3.0. "mpiexec" from openmpi-master reports "NVIDIA: no NVIDIA
devices found" if a machine isn't equipped with a Nvidia device.
loki fd1026 105 mpiexec --host nfs1 hostname
NVIDIA: no NVIDIA devices found
nfs1
loki fd1026 106 which mpiexec

loki fd1026 111 which mpiexec
/usr/local/openmpi-2.1.2_64_gcc/bin/mpiexec
Both installations support CUDA.

I would be grateful, if somebody can fix the problem. Thank you very
much for any help in advance.
Kind regards
Siegmar
