is really special as the weights can be one of the following three
values (NULL, EMPTY or some legal value). As such, we need a complex
if to correctly convert the Fortran value to the corresponding C
value. Thus, always defining the c_ array is the simplest and most
straighforward approach.

This would be a really, really weird case if it ever happens (i.e.,
you have usnics but the agent process failed somewhere in MPI_INIT
such that the agent never appears), but having an infinite loop
doesn't seem like a good idea.
(does not need to go to v1.8 because v1.8 still uses RML for
communication for the connectivity checker)

This conservative fixes tries to fetch info from both
opal_dstore_nonpeer and opal_dstore_peer.
This is required is task A spawns tasks B and C.
B was previously unable to find info from C, this caused locality
info not being set and a hang in coll/ml init.
no CMR is required since v1.8 uses a unique dstore

Revamp the ORTE global data structures to reduce memory footprint and add new features. Add ability to control/set cpu frequency, though this can only be done if the sys admin has setup the system to support it (or you run as root).
This commit was SVN r31916.
We were still leaking 1) file descriptors for data files, and 2) some
control files. I fixed both of these leaks and everything is looking
good. This should fix the bug where we are running out of file
descriptors when running the loop_spawn test. I also too the
opportunity to refactor the code a bit to make the mapping/unmapping
simpler. This should help avoid these sorts of issues in the future.
Depends on #4678

Per Ralph :
"I noticed that we are incrementing and decrementing the opal_progress_event state.
However, this no longer has any impact whatsoever on the RML as that is running in
the independent ORTE event thread. So all this actually does is impact the MPI layer
by adding an unnecessary overhead."
Thanks Ralph for pointing this :-)

Now that the infrastructure is calling BTL del_procs() before the BTL
finalize(), the usnic BTL had to re-order some of its teardown
sequence to avoid assert() failing.
This is part of a larger conversation involving #4669. Since
MPI_FINALIZE and MPI_COMM_DISCONNECT currently use an
oob/grpcomm-based barrier, the usnic BTL can ''absolutely know'' that
these endpoints and procs will no longer be used. If the ORTE DPM
goes back to a PML-based barrier, the usnic BTL will need to grow more
complex teardown semantics (a la TCP socket FIN/ACK/FIN_WAIT states).

The following Trac tickets were found above:

to be based on grpcomm (i.e., an out-of-band based barrier) rather
than the simplistic PML-based barrier that it currently uses.
This is pending a larger discussion with Nathan and George, but it
will allow the usnic BTL to stop assert()-failing in light of the
recent del_procs() change.
This commit was SVN r31870.
Based on a suggestion from George on #31806, use the pre-computed
sizes rather than duplicating the computation math (which may change
someday in the future).

This commit fixes two issues:
- This intent of the code @ bml_r2.c:486 is to prevent calling the
btl_del_procs more than once for a given proc. Gilles correctly
identified there was a problem in this code but r31786 we not the
correct fix.
- Fix a segmentation fault in r2 finalize revealed by the fact we
actually call del_procs now.

MPI_Isend.
I filed an RFC for this optimization some time back. It is a
relatively simple optimization. If the data associated with an
MPI_Isend can be put on the wire without allocating an MPI_Request
then do so. In this case we can legally return omp_request_empty
which will correctly indicate that the request is complete and that is
was not cancelled (these are the only requirements on send requests).

This commit was SVN r31828.
Basesmuma was vallocing space for control data then mmapping over that
data. Nothing in the code suggests any need for mmapping a specific
address so I did the following to remove the leak:
- Removed the valloc of the buffer space
- ftruncate the mmaped file to ensure there is sufficient memory to
allocate space for the control data.
Ideally this code should be using opal/shmem but that is a larger
change. Keeping it simple for now.
