Hi,
I have installed openmpi-2.1.0rc4 on my "SUSE Linux Enterprise Server
12.2 (x86_64)" with Sun C 5.14 and gcc-6.3.0. Sometimes I get once
more a warning about a missing item for one of my small programs (it
doesn't matter if I use my cc or gcc version). My gcc version also
displays the message

Apparently there is, or at least with ompi 1.10. I've now realized IMB
pingpong latency on a QDR IB system with ompi 1.10.6+libfabric is
~2.5μs, which it isn't with ompi 1.6 openib.

Hi Siegmar,
I think this "NVIDIA : ..." error message comes from the fact that you
add CUDA includes in the C*FLAGS. If you just use --with-cuda, Open MPI
will compile with CUDA support, but hwloc will not find CUDA and that
will be fine. However, setting CUDA in CFLAGS will make hwloc find CU
Hi Siegmar,
Would it possible for you to provide the source to reproduce the issue?
Thanks

Hi Silvain,
I get the "NVIDIA : ..." run-time error messages just by compiling
with "--with-cuda=/usr":
./configure --prefix=${prefix} \
--mandir=${prefix}/share/man \
--infodir=${prefix}/share/info \
--sysconfdir=/etc/openmpi/${VERSION} --with-
If you installed CUDA libraries and includes in /usr, then it's not
surprising hwloc finds them even without defining CFLAGS.
I'm just saying I think you won't get the error message if Open MPI
finds CUDA but hwloc does not.

Hi Akshay,

Yes, I've appended the file.
Kind regards
