Realistically, the usnic BTL doesn't need to know anything about the

get, namely: "hey, I wasn't able to make a connection to peer X", and
"hey, your connection to peer X has died."
This connectivity-checker runs in a separate progress thread in the
usnic BTL in local rank 0 on each server. Upon first send in any
process, the connectivty-checker agent will send some UDP pings to the
peer to ensure that we can reach it. If we can't, we'll abort the job
with a nice show_help message.

ibv_create_ah() may need to effect an ARP resolution, which may take
some time. Rather than blocking in ibv_create_ah(), the usNIC driver
may return NULL and set errno to EAGAIN indicating that we should try

So add a simple loop here to loop over ibv_create_ah() until it
returns non-(NULL+EAGAIN). A future commit will make this a bit more
efficient.

Prior to this commit we matched local interfaces to remote interfaces in
order to create endpoints in a simplistic way. If any remote interfaces
were on the same subnet as any of our local interfaces then only local
interfaces would be paired (IP-routed remote interfaces would be
ignored).
This commit introduces a more general scheme which attempts to make the
"best" pairing of local interfaces to remote interfaces. We now cast
the problem as a graph theory problem known as the "Assignment Problem",
or finding a maximum-cardinality, minimum-weight bipartite matching. We
solve this problem by reducing the bipartite graph of interface
connectivity to a flow network and then solving for a minimum cost flow.
This is then easily converted into back into a matching on the original
bipartite graph.
In the new scheme, interfaces on the same subnet are preferred over
interfaces requiring intermediate routing hops and higher bandwidth
links are preferred over lower bandwidth links.

This code is intended to support usNIC interface matching functionality.
We currently view that problem as essentially the "Assignment Problem"
(http://en.wikipedia.org/wiki/Assignment_problem), for which there are
many possible solution approaches, including flow-network analysis. In
the future, we might transition to a more nuanced view of the problem
which would likely also be flow-network based.
To this end, the current code focuses on providing one major algorithm
to the core usnic BTL: `ompi_btl_usnic_solve_bipartite_assignment`. It
also exposes several typical and necessary functions for constructing,
manipulating, and querying weighted, directed graphs.

still holds if two processes share any common subnets. However, if the

interfaces are reachable from all other interfaces and wire them up in a
1-1, randomly-matched order somewhat similarly to the "tcp" BTL's
behavior.

This commit decouples OMPI deployment from the version(s) of the lower
layers of the stack by probing for UDP support.
Verbs applications assume a 40-byte header (there is no current
mechanism for querying payload offset). So to support a 42-byte UDP
header without causing existing applications like ibv_ud_pingpong or
older versions of OMPI to crash, we must inform libusnic_verbs that we
are aware of the nonstandard payload offset. We do this by overriding
the `transport_type` field of the device to be 42 before calling
`ibv_open_device`. If the library resets it to something else, then we
know the lower layers are UDP capable. Otherwise we use the older
custom-L2 format.
This necessitated some minor ugliness in common_verbs, but it's as tidy
as Jeff and I know how to make it right now.
This commit only adds support for UDP headers and connectivity over the
same L2 network, it does not touch routing or interface pairing.

1. Changed rng_buff_t --> opal_rng_buff_t
2. All global variables obey the prefix rule
3. Old code has been removed
4. Found a couple of unnecessary includes

We're going to be bringing a bunch of usnic code to the SVN trunk
soon, and I basically brought this commit over out of order. So I'm
reverting it for now; the same functionality will come back shortly.
This commit was SVN r30805.
The following SVN revision numbers were found above:
r30804 --> open-mpi/ompi@5bedcc15bf
These constants are now upstream (see
https://git.kernel.org/cgit/libs/infiniband/libibverbs.git/commit/?id=f57a9c67eabb9e7f19c624ac3c8c27b7be55796c),
so let's support them properly in Open MPI.
Added bonus: consolidating these checks up in
ompi_check_openfabrics.m4 allowed removing some custom checks and
AC_DEFINE's from the usnic configure.m4 script.
Also change the usnic/configure.m4 check for IBV_EVENT_GID_CHANGE to
use AC_CHECK_DECLS (vs. AC_CHECK_DECL).

* Use the prefix rule for global variables
* Elimiante seed_prng() since it isn't necessary any more
These files will need to get edited again then the RNG type obeys the
prefix rule.

- Move the ptrdiff_t tests up higher in configure.ac to be with the
rest of the type tests.
- Create new OMPI_FIND_MPI_AINT_COUNT_OFFSET for finding the
corresponding types of MPI_Aint, MPI_Count, and MPI_Offset.
Consolidate all the old C and Fortran tests into this new macro (and
.m4 file).
- Fix Fortran MPI_*_KIND tests that incorrectly keyed off assumed
types (e.g., int64_t) rather than whatever the corresponding C
MPI_Aint, MPI_Count, MPI_Offset types turned out to be.
- Add new logic to ensure that sizeof(MPI_Count) <= sizeof(size_t),
because our entire PML, BTL, and convertor infrastructure requires
this. As a side effect, just like MPI_Offset the same type of
MPI_Count (because MPI_Count has to be able to hold an MPI_Offset,
so we can't let MPI_Offset be larger than a MPI_Count).

Optimization of the MPI_Dims_create function which omits the usage of pre
calculated prime numbers and factorize directly as discussed at the developer
list.

Freeprocs variable was obtained from nnodes, so check the value of nnodes at
the begin in the MPI_PARAM_CHECK code section instead as discussed at the
developer list.
