Open MPI was unable to find threading support on your system. The
|
|
OMPI development team is considering requiring threading support for
|
|
proper OMPI execution. This is in part because we are not aware of
|
|
any OpenFabrics users that do not have thread support -- so we need
|
|
you to e-mail the Open MPI Users mailing list to tell us if this is a
|
|
problem for you.
