@ggouaillardet New commit added to this v2.x PR. |
(originally cherry picked from master, but since the hwloc component was updated between master and v2.0.x but are the same between v2.0.x and v2.x, I cherry picked from the v2.0.x branch for the v2.x branch) Signed-off-by: Jeff Squyres <[email protected]> (cherry picked from commit f5d51dc) (cherry picked from commit 3b01bbe)
Open MPI doesn't use GL or OpenCL OS devices, so just disable them in hwloc. (originally cherry picked from master, but since the hwloc component was updated between master and v2.0.x but are the same between v2.0.x and v2.x, I cherry picked from the v2.0.x branch for the v2.x branch) Signed-off-by: Jeff Squyres <[email protected]> (cherry picked from commit 84a721d) (cherry picked from commit ca0973a)
Be a little more deliberate about convering OMPI's --with-cuda CLI value to hwloc's --enable-cuda configure option. Also, unconditionally disable hwloc NVML support (because Open MPI is not currently using it). Signed-off-by: Jeff Squyres <[email protected]> (cherry picked from commit 2ec2a32)

There is no usage of CUDA hwloc objects in the v2.x branch, and linking in CUDA can cause problems (per open-mpi#4257 (comment)). Partially cherry-picked from c341b53. Signed-off-by: Jeff Squyres <[email protected]>
