Hi all,
I am experiencing a rather unpleasant issue with a simple OpenMPI app. I have 4
nodes communicating with a central node. Performance is good and the
application behaves as it should. (i.e. performance steadily decreases as I
increase the work size). My problem is that immediately

The application sends an integer from the rank 0 process to the rank 1 process.
The sequence of code that I use to accomplish this is the following:
if (rank == 0)
{
