That is definitely the correct action.
Hi list,
I'm currently playing with thread levels in Open MPI and I'm quite
surprised by the current code.
First, the C interface :
at ompi/mpi/c/init_thread.c:56 we have :
#if OPAL_ENABLE_MPI_THREADS
*provided = MPI_THREAD_MULTIPLE;
#else
*provided = MPI_THREAD_SINGLE;
#endif
