There is some level of support for thread safety. However, we're actively working on this for our next release (1.3).

I have a question regarding the thread-safety features of Open MPI. I have a multithreaded program in which two threads make MPI calls, so these threads might call MPI functions concurrently. Can Open MPI support such a program, i.e., is it thread-safe in such a scenario? I know that according to Open MPI FAQ, Open MPI should be able to support such a program; however, I am slightly confused because some questions (and their answers) in the archive of this mailing list seem to suggest otherwise.
