2acd0f83de Revert "Revert r27451 and r27456 - the cmd line parser is incorrectly marking the application as an MCA parameter".
It appears the problem was not with the command line parser but the rsh plm. I don't know why this problem was not occuring before the command line parser changes but it appears to be resolved now.

c82cfecc1c Cleanup comm_spawn for the multi-node case where at least one new process isn't spawned on every node. Avoid the complexities of trying to execute a daemon collective across the dynamic spawn as it becomes too hard to ensure that all daemons participate or are accounted for - instead, use a less scalable but workable solution of sending the data directly between the participating procs. Ensure that singletons get their collectives properly defined at startup so the spawned "HNP" is ready for them.
As a secondary cleanup, the HNP doesn't need to update its nidmap during an xcast as it already has an up-to-date picture of the situation. So just dump that data and move along.

fa6a18f05a If the orted HNP is spawned by a singleton, then it needs to harvest all the MCA params from its environment to ensure they are passed on to any subsequently spawned daemons. Otherwise, the singleton could be directed to select options that other apps miss.

98580c117b Introduce staged execution. If you don't have adequate resources to run everything without oversubscribing, don't want to oversubscribe, and aren't using MPI, then staged execution lets you (a) run as many procs as there are available resources, and (b) start additional procs as others complete and free up resources. Adds a new mapper as well as a new state machine.
Remove some stale configure.m4's we no longer need.

Optimize the nidmaps a bit by only sending info that has changed each time, instead of sending a complete copy of everything. Makes no difference for the typical MPI job - only impacts things like staged execution where we are sending multiple (possibly many) launch messages.

0dfe29b1a6 Roll in the rest of the modex change. Eliminate all non-modex API access of RTE info from the MPI layer - in some cases, the info was already present (either in the ompi_proc_t or in the orte_process_info struct) and no call was necessary. This removes all calls to orte_ess from the MPI layer. Calls to orte_grpcomm remain required.
Update all the orte ess components to remove their associated APIs for retrieving proc data. Update the grpcomm API to reflect transfer of set/get modex info to the db framework.

Note that this doesn't recreate the old GPR. This is strictly a local db storage that may (at some point) obtain any missing data from the local daemon as part of an async methodology. The framework allows us to experiment with such methods without perturbing the default one.

96c778656a Improve launch performance on clusters that use dedicated nodes by instructing the orteds to use the same port as the HNP, thus allowing them to "rollup" their initial callback via the routed network. This substantially reduces the HNP bottleneck and the number of ports opened by the HNP.
Restore enable-static-ports option by default - the Cray will have to disable it to get around their library issues, but that's just a warning problem as opposed to blocking the build.

7f9ae11faf Per http://www.open-mpi.org/community/lists/users/2011/11/17862.php,
to make MPI_IN_PLACE (and other sentinel Fortran constants) work on OS
X, we need to use the following compiler (linker) flag:

    -Wl,-commons,use_dylibs 

So if we're compiling on OS X, test to see if that flag works with the
compiler.  If so, add it to the wrapper FFLAGS and FCFLAGS (note that
per a future update, we'll only have one Fortran compiler anyway).

Fixes trac:1982.

9b59d8de6f This is actually a much smaller commit than it appears at first glance - it just touches a lot of files. The --without-rte-support configuration option has never really been implemented completely. The option caused various objects not to be defined and conditionally compiled some base functions, but did nothing to prevent build of the component libraries. Unfortunately, since many of those components use objects covered by the option, it caused builds to break if those components were allowed to build.
Brian dealt with this in the past by creating platform files and using "no-build" to block the components. This was clunky, but acceptable when only one organization was using that option. However, that number has now expanded to at least two more locations.

Accordingly, make --without-rte-support actually work by adding appropriate configury to prevent components from building when they shouldn't. While doing so, remove two frameworks (db and rmcast) that are no longer used as ORCM comes to a close (besides, they belonged in ORCM now anyway). Do some minor cleanups along the way.

6310361532 At long last, the fabled revision to the affinity system has arrived. A more detailed explanation of how this all works will be presented here:
https://svn.open-mpi.org/trac/ompi/wiki/ProcessPlacement

The wiki page is incomplete at the moment, but I hope to complete it over the next few days. I will provide updates on the devel list. As the wiki page states, the default and most commonly used options remain unchanged (except as noted below). New, esoteric and complex options have been added, but unless you are a true masochist, you are unlikely to use many of them beyond perhaps an initial curiosity-motivated experimentation.

In a nutshell, this commit revamps the map/rank/bind procedure to take into account topology info on the compute nodes. I have, for the most part, preserved the default behaviors, with three notable exceptions:

1. I have at long last bowed my head in submission to the system admin's of managed clusters. For years, they have complained about our default of allowing users to oversubscribe nodes - i.e., to run more processes on a node than allocated slots. Accordingly, I have modified the default behavior: if you are running off of hostfile/dash-host allocated nodes, then the default is to allow oversubscription. If you are running off of RM-allocated nodes, then the default is to NOT allow oversubscription. Flags to override these behaviors are provided, so this only affects the default behavior.

2. both cpus/rank and stride have been removed. The latter was demanded by those who didn't understand the purpose behind it - and I agreed as the users who requested it are no longer using it. The former was removed temporarily pending implementation.

3. vm launch is now the sole method for starting OMPI. It was just too darned hard to maintain multiple launch procedures - maybe someday, provided someone can demonstrate a reason to do so.

As Jeff stated, it is impossible to fully test a change of this size. I have tested it on Linux and Mac, covering all the default and simple options, singletons, and comm_spawn. That said, I'm sure others will find problems, so I'll be watching MTT results until this stabilizes.

d28dd55d33 Minimize the amount of topology info returned by the daemons. Most clusters, especially at scale, use the same node topology on every node, so there is no re
ason to return the topology from every daemon. Borrow a page from the --hetero-apps page and let users indicate that the node topology differs by adding a --
hetero-nodes option to mpirun. If the option is set, then every daemon returns topology info. If not set, then only daemon vpid=1 returns it.

We always want one daemon to return the topology as the head node is often different from the compute nodes. Having one daemon return the compute node topolo
gy allows us to detect any such difference. All compute nodes are then set to the same topology.

b771114086 Fix the fix :-)
If the errmgr is going to try and hold the orted until all routes and children are gone, then the exit cmd must do the same. Otherwise, the orted exits immediately without waiting for routes to be dismantled, which is why we don't see the connections close.

Also cleanup some diagnostics and add some debug to more clearly see what's going on.

b42ccc89b8 Although this didn't solve the earlier termination problem, the code will be required once we get connection terminations properly detected.

f1a3a35fcd Cannot rely on detection of connection terminations for deciding when to exit as they don't always go away immediately. There is no info coming back anyway, so it's okay to just exit once the relay has been sent. The relay is sent via a blocking API, so just go ahead and quit.

92c7372e20 Per the RFC from Jeff, move hwloc from opal/mca/common to its own static framework ala libevent. Have ORTE daemons collect the topology info at startup and, if --enable-hwloc-xml is set, send that info back to the HNP for later use. The HNP only retains unique topology "templates" to reduce memory footprint. Have the daemon include the local topology info in the nidmap buffer sent to each app so the apps don't all hammer the local system to discover it for themselves.
Remove the sysinfo framework as hwloc replaces that functionality.

1ad110d2e9 After a nice, calm, rational discussion between Brian, Jeff, and myself, we decided to revert r24864 and r24862 to restore the reference counters in opal_init/finalize. The rationale was that we should instead change orte_init/finalize to also use reference counters to support multi-embedded libraries. Jeff and Brian will discuss proposing a similar change to mpi_init/finalize to the MPI Forum so that all three libraries will behave in similar manners.
It was agreed that opal_init_util had wound up being used in unintended ways, which raised the problem of getting reference counts to work right. However, fixing it would involve more pain than it was worth - and so long as the other layers are made to behave similarly, I have no preference either way.

Complete implementation will follow - for now, this just reverts the prior changes.

1ee7c39982 Fix some major bit-rot on scalable launch. If static ports are provided, then daemons can connect back to the HNP via the routed connection tree instead of doing so directly. In order to do that at scale, the node list must be passed as a regular expression - otherwise, the orted command line gets too long.
Over the course of time, usage of static ports got corrupted in several places, the "parent" info got incorrectly reset, etc. So correct all that and get the regex-based wireup going again.

Also, don't pass node lists if static ports aren't enabled - they are of no value to the orted and just create the possibility of overly-long cmd lines.
