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.
