btl_tcp_disable_family=4 and btl_tcp_disable_family=6 are mutually
...
exclusive, so this should result in "unreachable" when set differently
between peers.

Added new oob-tcp parameter oob_tcp_disable_family.
...
Like btl_tcp_disable_family, this parameter more or less disables
a whole address family. Though the sockets are still created, the
corresponding information isn't added to the connection strings.
Likewise, we don't try to connect to addresses matching the disabled
address family.
This is particularly important for multidomain clusters, where IPv4 is
oftenly filtered (firewalled), sometimes by simply dropping the packets
instead of rejecting them (thus causing a connection timeout instead of
a quick "no route to host").

Add a binomial tree-based launch to ssh, turned "on" only when the plm_rsh_tree_spawned mca param is set to a non-zero value. This probably isn't a very optimized capability, but it does execute a tree-based launch that may scale better than linear at high node counts.
...
Add the daemon map capability to the ODLS to create and save a map of daemon vpid vs nodename from the launch message.
Cleanup a few places in the base plm launch support where we didn't adequately protect rml recv's from potentially executing sends.

Potential double free of locks
...
mca_btl_openib_endpoint_post_rr_nolock is freeing the endpoint lock on

regardless of its error case. Thus resulting is a double free of the
lock.

Consolidate the daemon wireup message into the launch message. The daemons don't need their contact info prior to the launch message anyway. This not only eliminates a job-wide communication from the startup procedure, but it also resolves a race condition reported when operating across highly distributed (i.e., cross-country) networks. In such scenarios, it proved possible for a daemon to receive its launch message -before- it had received the contact info message, even though the latter had been sent first!
...
This eliminates that problem...

Sorry, previous commit was in the wrong directory. This is the real fix (have
...
to undo 1822).
The verification of recvcount==0 and rank = root was braking
inter-communicator scatter, since the root (root==MPI_ROOT) might very well
have recvcount=0. The same fix has been applied to gather.c just the other way
round.
Fixes the bug reported on the mainling list by Martin Audet. If there is a
1.2.7 this fix might be worthwhile porting it over.
Please note, that while the test works now for basic and for inter, we get a
0byte malloc warning from the inter module, which we still have to fix in a
separate patch.

Given total lack of interest/support from the folks behind these environments, and the fact that we can now scale so well with our own daemons, it seems unlikely that we will be able to pursue direct and/or standalone launch in these environments. If that situation ever changes, it is easy enough to revive the effort since little had really been done to-date.
...
Meantime, no reason to continue dragging these around.

Now that we have the daemon collectives, the unity routed module no longer needs the "hack" we inserted a week ago to tell the daemons how to talk directly to all the application procs. The modex and barrier messages flow cleanly across the daemons and are "dropped" into the procs where required.
...
Add some insurance to make certain that the daemons' number of procs only gets updated when it absolutely is intended.
