For some historical reasons, we didn't use select() for the Windows events. Now it could be merged back to have a better performance on Windows.

1. finalize the logic for properly respecting externally assigned bindings. Thanks to Chris Samuel for his help with this. Still needs some acid testing, but appears to now work.
2. remove the double-logic of requiring opal_paffinity_alone AND bind-to-foo. If the user specifies bind-to-foo, trust her and just do it.

Add a capability to parse the rankfile to extract node information in place of requiring both hostfile and rankfile for non-RM managed environments. The rankfile is -only- parsed for this IF the hostfile and -host options are not given. Otherwise, those are used to establish allocation info as we did before this commit.
This commit was SVN r21815.
Adds several new mpirun options:
* -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding.
* -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned.
* -bind-to-core - currently the default behavior (maintained from prior default)
* -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile
Similar features/options are provided at the board level for multi-board nodes.

Remove all architecture references from ORTE and put them back in the modex using modex_send/recv calls.
Hetero operations are now fully supported again. Comm_spawn now works up to the point where it segfaults due to an error in the CID code - which now allows Edgar to dig further! :-)
This commit was SVN r21655.
Emit a more informative error message when the file descriptor limit is
reached during an accept() call. Also, abort when the accept fails to
avoid an infinite loop.
Emit a more informative error message when the help file can't be opened.

The following Trac tickets were found above:
Ticket 1930 --> https://svn.open-mpi.org/trac/ompi/ticket/1930
This causes the orteds in the routing tree to remain alive until all termination "acks" from orteds below them have passed through. Thus, if we use static ports, we no longer require a direct orted-to-mpirun connection.
Also modify the binomial routed module so it conforms to what all the other routed modules do and have all messages pass along the routing tree instead of short-circuiting between orteds. This further reduces the number of ports being opened on backend nodes.

* Pass the sequence number of the checkpoint along with reference from the global to the local coordinator.
* 'orte-restart --apponly' now just generates the app context file, and does not run with it. This provides the user the ability to edit the file before launching.
* Add a OPAL_CRS_NONE state
* Split the INC into three distinct parts.
* Implement a restart mechanism for the 'none' component. If given a context it simply execvp()'s it.
This commit was SVN r21195.
* Add 'orte-checkpoint -l' option that lists all checkpoints currently available on the system.
* Add 'orte-restart -i' which prints information regarding the checkpoint targeted for restart.
* Add ability to extract the timing metadata.
* Fix show_help() in the orte-checkpoint and orte-restart tools. They should be using the opal versions instead of the orte versions (otherwise nothing is printed).

OMPI_* to OPAL_*. This allows opal layer to be used more independent
from the whole of ompi.
NOTE: 9 "svn mv" operations immediately follow this commit.
This commit was SVN r21180.
* Improved timing in SnapC Full Global Coordinator
* Improved scalability of the SnapC Full protocol
* Minor improvements to the error reporting mechanisms in SnapC and FileM
* Improved the memory usage of the metadata routines - now the owner of the data is more explicit.
* Added a FileM hint to indicate when files stored locally can be moved to/from a globally mounted file system using just the 'cp' command instead of the 'rcp/scp' command. Slightly improves performance, but not too drastically. Can be set using the following SnapC MCA parameter: {{{snapc_base_global_shared=1}}}
* Implement the ability to throttle the number of outgoing connections in FileM. At larger scales this type of explicit throttling helps prevent overwhelming the HNP machine. Default: 10, set via MCA parameter: {{{filem_rsh_max_outgoing}}}
* Add a few diagnostic/debugging features to SnapC and FileM.
This commit was SVN r21131.
Cleanup the termination in orterun when abnormally commanded via ctrl-c. We can just directly terminate_orteds as the orteds always kill any lingering local procs before exiting - no need to do the two-step cha-cha.

- Delete unnecessary header files using
contrib/check_unnecessary_headers.sh after applying
patches, that include headers, being "lost" due to
inclusion in one of the now deleted headers...
In total 817 files are touched.
In ompi/mpi/c/ header files are moved up into the actual c-file,
where necessary (these are the only additional #include),
otherwise it is only deletions of #include (apart from the above
additions required due to notifier...)
- To get different MCAs (OpenIB, TM, ALPS), an earlier version was
successfully compiled (yesterday) on:
Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled
This commit was SVN r21096.
several header files (previously included by header-files)
now have to be moved "upward".
This is mainly system headers such as string.h, stdio.h and for
networking, but also some orte headers.
This commit was SVN r21095.
generate mangled windex files. Made ompi-top.1 and ompi-iof.1 build
by default. Also, added the orte-top synonym to the ompi-top manpage.
This commit was SVN r20915.
In case we use memcmp, strlen, strup and friends include <string.h>
Also several constants.h are not included directly
- Let's have mca_topo_base_cart_create return ompi-errors in
ompi/mca/topo/base/topo_base_cart_create.c
