Subject: [OMPI users] Open MPI and thread-safety
From: Priya Natarajan (priya.natarajan_at_[hidden])

Hi,

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?

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.

Regards,
Priya Natarajan
