change is a difference between the released 1.3/1.4 series.
The Voltaire FCA library uses these strings for its own internal
purposes; since the names changed between the 1.3/1.4 series and the
upcoming 1.5 series, it caused a problem for the FCA library. They
volunteered to put in a hot fix in FCA, but it seems to me that we

Documentation:

Major Changes:
--------------
* Added C/R-enabled Debugging support.
Enabled with the --enable-crdebug flag. See the following website for more information:
http://osl.iu.edu/research/ft/crdebug/
* Added Stable Storage (SStore) framework for checkpoint storage
* 'central' component does a direct to central storage save
* 'stage' component stages checkpoints to central storage while the application continues execution.
* 'stage' supports offline compression of checkpoints before moving (sstore_stage_compress)
* 'stage' supports local caching of checkpoints to improve automatic recovery (sstore_stage_caching)
* Added Compression (compress) framework to support
* Add two new ErrMgr recovery policies
* {{{crmig}}} C/R Process Migration
* {{{autor}}} C/R Automatic Recovery
* Added the {{{ompi-migrate}}} command line tool to support the {{{crmig}}} ErrMgr component
* Added CR MPI Ext functions (enable them with {{{--enable-mpi-ext=cr}}} configure option)
* {{{OMPI_CR_Checkpoint}}} (Fixes trac:2342)
* {{{OMPI_CR_Restart}}}
* {{{OMPI_CR_Migrate}}} (may need some more work for mapping rules)
* {{{OMPI_CR_INC_register_callback}}} (Fixes trac:2192)
* {{{OMPI_CR_Quiesce_start}}}
* {{{OMPI_CR_Quiesce_checkpoint}}}
* {{{OMPI_CR_Quiesce_end}}}
* {{{OMPI_CR_self_register_checkpoint_callback}}}
* {{{OMPI_CR_self_register_restart_callback}}}
* {{{OMPI_CR_self_register_continue_callback}}}
* The ErrMgr predicted_fault() interface has been changed to take an opal_list_t of ErrMgr defined types. This will allow us to better support a wider range of fault prediction services in the future.
* Add a progress meter to:
* FileM rsh (filem_rsh_process_meter)
* SnapC full (snapc_full_progress_meter)
* SStore stage (sstore_stage_progress_meter)
* Added 2 new command line options to ompi-restart
* --showme : Display the full command line that would have been exec'ed.
* --mpirun_opts : Command line options to pass directly to mpirun. (Fixes trac:2413)
* Deprecated some MCA params:
* crs_base_snapshot_dir deprecated, use sstore_stage_local_snapshot_dir
* snapc_base_global_snapshot_dir deprecated, use sstore_base_global_snapshot_dir
* snapc_base_global_shared deprecated, use sstore_stage_global_is_shared
* snapc_base_store_in_place deprecated, replaced with different components of SStore
* snapc_base_global_snapshot_ref deprecated, use sstore_base_global_snapshot_ref
* snapc_base_establish_global_snapshot_dir deprecated, never well supported
* snapc_full_skip_filem deprecated, use sstore_stage_skip_filem
Minor Changes:
--------------
* Fixes trac:1924 : {{{ompi-restart}}} now recognizes path prefixed checkpoint handles and does the right thing.
* Fixes trac:2097 : {{{ompi-info}}} should now report all available CRS components
* Fixes trac:2161 : Manual checkpoint movement. A user can 'mv' a checkpoint directory from the original location to another and still restart from it.
* Fixes trac:2208 : Honor various TMPDIR varaibles instead of forcing {{{/tmp}}}
* Move {{{ompi_cr_continue_like_restart}}} to {{{orte_cr_continue_like_restart}}} to be more flexible in where this should be set.
* opal_crs_base_metadata_write* functions have been moved to SStore to support a wider range of metadata handling functionality.
* Cleanup the CRS framework and components to work with the SStore framework.
* Cleanup the SnapC framework and components to work with the SStore framework (cleans up these code paths considerably).
* Add 'quiesce' hook to CRCP for a future enhancement.
* We now require a BLCR version that supports {{{cr_request_file()}}} or {{{cr_request_checkpoint()}}} in order to make the code more maintainable. Note that {{{cr_request_file}}} has been deprecated since 0.7.0, so we prefer to use {{{cr_request_checkpoint()}}}.
* Add optional application level INC callbacks (registered through the CR MPI Ext interface).
* Increase the {{{opal_cr_thread_sleep_wait}}} parameter to 1000 microseconds to make the C/R thread less aggressive.
* {{{opal-restart}}} now looks for cache directories before falling back on stable storage when asked.
* {{{opal-restart}}} also support local decompression before restarting
* {{{orte-checkpoint}}} now uses the SStore framework to work with the metadata
* {{{orte-restart}}} now uses the SStore framework to work with the metadata
* Remove the {{{orte-restart}}} preload option. This was removed since the user only needs to select the 'stage' component in order to support this functionality.
* Since the '-am' parameter is saved in the metadata, {{{ompi-restart}}} no longer hard codes {{{-am ft-enable-cr}}}.
* Fix {{{hnp}}} ErrMgr so that if a previous component in the stack has 'fixed' the problem, then it should be skipped.
* Make sure to decrement the number of 'num_local_procs' in the orted when one goes away.
* odls now checks the SStore framework to see if it needs to load any checkpoint files before launching (to support 'stage'). This separates the SStore logic from the --preload-[binary|files] options.
* Add unique IDs to the named pipes established between the orted and the app in SnapC. This is to better support migration and automatic recovery activities.
* Improve the checks for 'already checkpointing' error path.
* A a recovery output timer, to show how long it takes to restart a job
* Do a better job of cleaning up the old session directory on restart.
* Add a local module to the autor and crmig ErrMgr components. These small modules prevent the 'orted' component from attempting a local recovery (Which does not work for MPI apps at the moment)
* Add a fix for bounding the checkpointable region between MPI_Init and MPI_Finalize.

#define CACHE_LINE_SIZE to 128. This name has a conflict on NetBSD,
and it seems kinda odd to have a header file that ''only'' defines a
single value. Also, we'll soon be raising hwloc to be a first-class
item, so having this file around seemed kinda weird.
Therefore, I replaced CACHE_LINE_SIZE with opal_cache_line_size, an
int (in opal/runtime/opal_init.c and opal/runtime/opal.h) on the
rationale that we can fill this in at runtime with hwloc info (trunk
and v1.5/beyond, only). The only place we ''needed'' a compile-time
CACHE_LINE_SIZE was in the BTL SM (for struct padding), so I made a
new BTL_SM_ preprocessor macro with the old CACHE_LINE_SIZE value
(128). That use isn't suitable for run-time hwloc information,
anyway.

This is problematic for the OPAL_SOS stuff. This commit changes those
functions to always return OPAL_* statuses and send the output value
back through output parameters (like 95% of the rest of the code
base). This avoids the confusion with OPAL_SOS stuff and makes
paffinity work again (e.g., mpirun --bind-to-core ...).
I updated all paffinitiy modules for the new function signatures, and
bumped the paffinity API version up to 2.0.1. I don't think the

The fix is to just check if the return value is positive or not, since all the SOS encoded errors are *always* negative.

Short version: there is a bug in OS X/Snow Leopard, but there is also
a bug in Open MPI. Fixing the bug in Open MPI is both trivial (a
1-line change) and avoids the bug in OS X. We'll file an OS X bug
report upstream with Apple, but it should no longer affect us here in
OMPI.
Fixes trac:2039.
More details:
Some background first:
1. IPv4 sockets can only accept incoming IPv4 connections. However,
IPv6 sockets can be configured to accept ''only'' incoming IPv6
connection, or ''both'' incoming IPv4 and IPv6 connections. An
IPv6 socket attribute sets which listening behavior is used.
1. IPv4 and IPv6 have different port namespaces. Hence, it is
permissable to bind a v4 socket to port X ''and'' also bind a v6
socket to that same port X on the same interface (assuming that
the v6 socket is only accepting incoming v6 connections).
Incoming v4 connections to port X on the interface should get
matched to the listening v4 socket; incoming v6 connections should
get matched to the listening v6 socket.
1. When v6 sockets accept ''both'' incoming v4 and v6 connections, it
should claim port X in both namespaces.
1. Linux's default behavior is to only allow one listening socket to
be bound to a given port (i.e., ''either'' a v6 or v4 socket to be
bound to a single port X -- not both). A v6 socket can listen for
both v4 and v6 incoming connections on that port, but still --
only one socket will be bound to that port.
1. Snow Leopard's default behavior is to share ports -- i.e., let
both a v4 and a v6 listening socket to be bound to port X
(assuming that the v6 socket is only accepting incoming v6
connections).
The TCP BTL creates a listening socket for each address family.
Hence, it creates a v4 listening socket on INADDR_ANY and a v6
listening socket on the v6 equivalent of INADDR_ANY. OMPI then
iteratively tries to find ports to listen on within the range of
[mca_btl_tcp_port_min, mca_btl_tcp_port_min + mca_btl_tcp_port_range).
On Linux, the v4 socket will be bound to port X and the v6 socket will
likely be bound to port Y (where X != Y). On Snow Leopard, the v4
socket will be bound to port X and the v6 socket may ''also'' be bound
to port X. Since the namespaces are separate, this shouldn't be a
problem.
However, Open MPI was accidentally setting the v6 listening behavior
to accept ''both'' v4 and v6 incoming connections. This is a trivial
thing to fix -- change a 0 to a 1 in the code. On Linux, this issue
didn't matter because the v4 and v6 sockets were on different ports.
So even though the v6 socket ''would'' have accepted incoming v4
connections, that never happened because OMPI would direct v4
connections to the v4 port.
But on Snow Leopard, the v4 and v6 listening ports could end up
sharing the same port number. As mentioned above, this ''shouldn't''
have been a problem, but it looks like Snow Leopard has the following
bugs:
* If a v4 socket is already bound to port X, we're pretty sure that a
v6 socket with the "accept both v4 and v6 incoming connections"
listening behavior should not be able to claim port X (because
there's already a v4 socket listening on X). However, Snow Leopard
would allow binding a v4 socket to port X, and then allow a v6
socket configured to allow incoming v4 and v6 connections to
''also'' be bound to port X.
* After binding the v6 socket to port X, Snow Leopard then lets
''another'' v4 socket ''also'' get bound to port X. Hence, there's
now '''three''' sockets all listening on port X.
This obviously led to mis-matched TCP connections, and things went
downhill from there.
That being said, Snow Leopard doesn't exhibit this behavior if v6
sockets only allow incoming v6 connections. And technically, that is
exactly the behavior we want (we want v6 sockets to only accept
incoming v6 connections). So if we just change the flag to make our
v6 listening socket us this behavior, the problem on OS X goes away.
That's what this commit does -- it changes a 0 to a 1, indicating
"only let this v6 socket allow incoming v6 connections."
That was simple, wasn't it?

Ticket 2039 --> https://svn.open-mpi.org/trac/ompi/ticket/2039
1. The code that looks at btl_tcp_if_exclude before doing a
modex_send uses strcmp rather than strncmp. That means that
"lo0" gets sent even though "lo" is excluded.
2. The code that determines whether a particular local TCP
interface can connect to a particular remote interface doesn't
check for loopback interfaces. With this fix, users can now
enable "lo" and be assured that it will only be used for intra-
node communication.
