Nathan,
i uploaded this part to github :

you really need to check the last commit :

George,
i am sorry i cannot see how flatten datatype can be helpful here :-(
in this example, the master must broadcast a long vector. this datatype
is contiguous
so the flatten'ed datatype *is* the type provided by the MPI application.
how would pipelining happen in this case (e.g. who has to c
The ompi_datatype_flatten.c file appears to be missing. Let me know once
it is committed and I will take a look. I will see if I can write the
RMA code using it over the next week or so.

Hi,
In OFED-3.12 the API for XRC has changed. I did not find
corresponding changes in Open MPI: for example the function
'ibv_create_xrc_rcv_qp()' queried in openmpi configure script no
longer exists in ofed-3.12-rc1.
Are there any plans to support the new XRC API ?

WHAT: Remove data-heterogeneous support from Open MPI
WHY: No one uses it (it's not the default), it's broken (probably has been for
a while)
WHERE: Datatype engine, some configury, and a few other places

Yes, we plan to fix support for XRC due to the changes in 3.12. It will
probably not happen before 1.8.2 though.

Hello devel list
I've been trying to use a non-blocking MPI_Iallreduce in a CFD application I'm
working on, but it kept segfaulting on me. I have reduced it to a simple test
case - see the gist here for the full code

As maintainer of a different communications library over Verbs I'd like to
ask:
Where can one find information on the new APIs and their use?

Rupert,
You are right, the code of any non-blocking reduce is not built with
user-level op in mind. However, I'm not sure about your patch. One
reason is that ompi_3buff is doing target = source1 op source2 while
ompi_2buf is doing target op= source (notice the op=)
Thus you can't replace omp
