Fred, Unfortunatly it will not work. Embedded hwloc has its own configury logic and hence does not seem to interpret command line options. If hwloc is provided by your distro and fits your needs, you should use this one instead configure --with-hwloc=external Or configure --with-hwloc=DIR

Brice, An other option is to add a --with-hwloc-flags configure option to Open MPI, and pass the value to embedded hwloc configure. We already do that for ROMIO (--with-io-romio-flags) Cheers, Gilles On Tuesday, September 20, 2016, Brice Goglin wrote: > Hello >

Hello Assuming this NVML detection is actually done by hwloc, I guess there's nothing in OMPI to disable it. It's not the first time we get such an issue with OMPI not having all hwloc's --disable-foo options, but I don't think we actually want to propagate all of them. Maybe we should just force

Fred, Can you try to configure with --disable-nvml This is an option that should be passed to embedded hwloc. Cheers, Gilles On Tuesday, September 20, 2016, Fred Mioux wrote: > Hello , > > > > I compile OpenMPI on a machine which support CUDA and NVML, but I don’t >
