Changes (by Roland Haas):

status:

resolved (was new)

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

Keyword: MPI

Comment (by Roland Haas):

Fixed along with #1679 when updating OpenMPI's tarball to 4.0.2.
