Hi everybody!
We are working on a new, experimental interconnection network (the EXTOLL
network) and I am currently working on a MTL
component for that hardware. Actually, it works quite good :-)
Recently I included the RDMA mpool component for memory registration caching
into my code. Again, t

I see you remove support for #if
defined(HAVE_STRUCT_IBV_DEVICE_TRANSPORT_TYPE) -- that doesn't seem
like a good idea. We still have users on older OFED's without that
field.
Can you create a 1.5 ticket for this item?

Perhaps since we now have 2 levels of m4 checking that is necessary
(1) check to see if we have transport_type, and 2) check to see if
have RDMA_TRANSPORT_RDMAOE), perhaps it would be better to put all
these checks into a single place somewhere to avoid proliferating the
#if's for these 2 t

Ewww yikes. This could definitely be an issue if we weren't
(multi-thread) careful when writing these portions of the code. :-(

Note that the problems Chris is talking about *should* only occur if
you have compiled Open MPI with multi-threaded support. Did you do
that, perchance?
