Re: [OMPI users] Problem building OpenMPI with CUDA 8.0
Brice,
unless you want to enable/disable nvml at runtime, and assuming we do
not need nvml in Open MPI,
and IMHO, the easiest workaround is to update
https://github.com/open-mpi/ompi/blob/master/opal/mca/hwloc/hwloc1113/configure.m4
and add the oneliner
enable_nvml=no
a better option could be to update
https://github.com/open-mpi/ompi/blob/master/opal/mca/hwloc/configure.m4
and pass the --enable-nvml option from Open MPI down to hwloc.
Cheers,
Gilles

iirc, NVML is only used by hwloc (e.g. not by CUDA) and there is no
real benefit for having that.
as a workaround, you can
export enable_nvml=no
and then configure && make install

I have the release version of CUDA 8.0 installed and am trying to

Here is my configure and build line:
./configure --prefix=$PREFIXPATH --with-cuda=$CUDA_HOME --with-tm=

Where CUDA_HOME points to the cuda install path.
When I run the above command it builds for quite a while but
eventually errors out wit this:

Re: [OMPI users] Problem building OpenMPI with CUDA 8.0
After looking into this a bit more it appears that the issue is I am building
on a head node which does not have the driver installed. Building on back node
resolves this issue. In CUDA 8.0 the NVML stubs can be found in the toolkit at
the following path: ${CUDA_HOME}/lib64/stubs
For 8.0 I'd suggest updating the configure/make scripts to look for nvml there
