Hello,

I compile openmpi 1.2.3 with options ./configure --with-threads=posix
--enable-mpi-thread --enable-progress-threads --enable-smp-locks.

My program has 2 threads (main thread and an other). When i run it, i
can see 4 threads. I think that two threads are the progress threads, is
it right ?

Is it possible to disable these progress threads ?

I tried to compile openmpi with options ./configure
--with-threads=posix --enable-mpi-thread --disable-progress-threads
--enable-smp-locks, but when i run my program, i get the message :
Error! Cannot set MPI thread support to the desired value (asked for
MPI_THREAD_SERIALIZED and got MPI_THREAD_SINGLE).

Thanks,

Olivier.
