#2205: hwloc in OpenMPI self-built code uses CUDA and OpenCL
---------------------------------+-----------------------------------
 Reporter:  Roland Haas          |       Type:  defect
   Status:  new                  |   Priority:  major
Milestone:                       |  Component:  EinsteinToolkit thorn
  Version:  development version  |   Keywords:  MPI
---------------------------------+-----------------------------------
 This causes problems since we do not then link against CUDA or OpenCL.
 This happens even if one passes the {{{--with-cuda=no}}} option to
 OpenMPI's configure script.

 Possibly one has to follow the fix in OpenMPI's 2.x and 3.x branches to
 fix this: https://github.com/open-mpi/ompi/issues/4248
