Can you comment on what is going on here? It would be really good to
understand exactly what these 2 MLX4 parameters are (e.g., why you suggested
increasing one and not the other), and why there would be differences in
registering small numbers of large chunks of contiguous m

Jeff, All,
testing our well-known example of the registered memory problem (see
http://www.open-mpi.org/community/lists/users/2012/02/18565.php) on
freshly-installed 1.6.1rc2, found out that "Fall back to send/receive semantics"
did not work always it. However the behaviour has changed:
1.5.
1.6.1rc1 is a bust because of a compile error. :(
It wasn't caught on the build machine because it's a bug in the openib BTL, and
the build machine doesn't have OpenFabrics support.
1.6.1rc2 will be posted later today.

Finally! It's in the usual place:

Please test, especially with low-registered-memory-available scenarios with
Mellanox OpenFabrics devices.
Here's a list of changes since 1.6:
