that a) STATUS[ES]_IGNORE *is* NULL, and b) ROMIO blindly sends its
status through to STATUS_SET_ELEMENTS, even if the status is IGNORE.
So we have some legal cases where IGNORE can be passed through here.
Well, that's what we get for trying to do good error checking. :-(

- Fix some fpritnf's in ompi_mpi_abort() that incorrectly assumed that
we were always being invoked from MPI_ABORT (ompi_mpi_abort() may be
invoked from a bunch of different places)
- Also try to opal_backtrace_print() if opal_bactrace_buffer() is not
supported.
- Print a message in MPI_ABORT if we're aborting.

nothing as no one is making use of this ability. However, orte-clean

This is somewhat limited currently for expample, if you have 3 ports on Node A and 5 ports
on Node B then the peers will use 3 ports to communicate with each other.
This is on a subnet basis, so for any pair of nodes we take the
intersection of the available ports within a subnet.
We use subnets to determine reachability for lazy connection establishment. So
if Node A and Node B each have two HCA's (on seperate networks) then the
subnet's must be distinct, otherwise we will try to wire up HCA's on seperate
networks.

* Make sure that the pval always writes to the correct portion of the
lval. This only matters on 32 bit big endian machines.
* On 32 bit machines when assigning to pval, the other 4 bytes of lval
weren't being written, which could lead to bogus data
We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes. Refs trac:587

the value of __n holds. This is not a problem in the first case
because sizeof(int) == sizeof(MPI_Flogical), so no alloc is actually
performed (which is most compilers, and why we haven't been bitten by
this yet). But the second case -- where sizeof(int) !=
sizeof(MPI_Flogical) -- is definitely a problem and needs the "+1" in
the alloc, or Bad Things will happen.

This has now been corrected. The singleton startup will dutifully call the mapper framework so that the proper data storage locations get initialized. Unfortunately, we then had to instruct the RMAPS not to allocate a vpid range for this job - otherwise, it would make a mistake and think there were two processes in it. Hence, a change was required to RMAPS to tell it "map this job, but don't allocate a vpid range for it".
This change will need to migrate across to 1.2 after it "soaks" the appropriate time.

protocol over the MX BTL. Now, we have only one matching, the one in Open
MPI.
The problem is that when the unexpected handler is triggered, not all the
message is on the host memory. In the best case we get one MX fragment (internal
MX fragment), in the worst we get NULL. The only way to fit this with the
design of the PML is to force the eager protocol at the MX internal fragment
size, and to limit the send/receive protocol at the same size. Tests show
the outcome is not far from optimal (if the pipeline depth is increased
a little bit).
Set MX_PIPELINE_LOG in order to allow MX to use internal fragments of 4K.

performance on a 2G Myrinet card, as it look like pipelining the messages
by 1M is faster than a simple send/receive. However, when using a 10G card
the send/receive will limit the maximum bandwidth to 2.5Gbs. The reason is
the scarce bus resources that have to be shared between the Myrinet hardware
and the memcpy operation. The PUT protocol remove the memcpy, we now have a
true zero-copy mechanism. But, there is no pipelining yet as it look like the
RDMA pipeline somehow disappeared from the OB1 PML ...
