[Pympi-users] pyMPI + threading

[Vinicius P. <vpe...@ic...>]

Hi all!

pyMPI with threading support works alright? is it stable? with open
mpi for example...

is it possible to use MPI_THREAD_MULTIPLE... or what ? is there any limitation?

if not, could you send me some tips on how to use python + mpi +
threading in a safe manner? or some examples? any experience in this
issue is worth.

I was thinking about some design decision:
* use a Lock to provide exclusive access to mpi functions
* 1 thread in loop, executing "req = irecv()" and when some msg with a
type of TAG is available, it calls an appropriate function. it can use
some send functions inside too.
* other thread making some send calls...

what common mistakes should I avoid?

thanks in advance!
