more: - Remove OPAL_ENABLE_MULTI_THREADS, since it didn't really do anything correctly. Opal always has threads enabled at this point. - Remove OMPI_ENABLE_PROGRESS_THREADS, since this hasn't worked in 8 years and it has performance issues we'll never be able to overcome. Note that we have plans for re-adding async progress, using a hybrid protocol of async and sync sends. - OMPI_ENABLE_THREAD_MULTIPLE now determines whether the thread lock macros do the check or not. - Condition variables are ALWAYS polling right now, which fixes the thread live-lock currently found when THREAD_MULTIPLE is turned on. This commit was SVN r29891.

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.
