Subject: [OMPI users] Sending MPI-message from master to master
From: óÅÒÇÅÊ òÅÊÍÅÒÏ× (sergeyreym_at_[hidden])

I've not found any helpful information about possibility of sending
messages from a node of cluster to the same node (for example
MPI_Send(&f, 1, MPI_UNSIGNED_LONG_LONG, 0, 0, MPI_COMM_WORLD) from
node #0).
I wrote program with two threads and one thread MPI_Send message to
another thread that must it MPI_Recv. And such program freezes because
interlock occurs sometime (not always).
If it's possible I've attached cpp-file with example of problem.
Thanks a lot for your attantion.
