This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.
This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.
This commit closes trac:158
More details to follow.

The macro has not been needed since moving to configure types other than

* Make sure that the pval always writes to the correct portion of the
lval. This only matters on 32 bit big endian machines.
* On 32 bit machines when assigning to pval, the other 4 bytes of lval
weren't being written, which could lead to bogus data
We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes. Refs trac:587

allocation logic is completely done outside the data-type engine (in the PML) there is
no need for any special case inside the data-type engine. There is less arguments for
the ompi_convertor_pack and ompi_convertor_unpack as well (the last field free_after is
not required anymore as there is no memory allocated in the engine itself). This change
affect all components using datatypes. I test most of them, but it might happens that I
miss some ... If it's the case please let me know (don't shoot the pianist!!).
This commit was SVN r12331.
In order to provide backwards compatability the framework versions are bumped
and the handler registeration function is at the end of the btl struct.
Testing done on sm, openib, and gm..

interconnects that provide matching logic in the library.
Currently includes support for MX and some support for
Portals
* Fix overuse of proc_pml pointer on the ompi_proc structuer,
splitting into proc_pml for pml data and proc_bml for
the BML endpoint data
* bug fixes in bsend init code, which wasn't being used by
the OB1 or DR PMLs...

Do this rather than the my_list pointer because we need to do some
things that are somewhat special because we pre-pin eager fragments but
not send fragments. Also makes a couple ideas I have slightly easier to
play around with.
This commit was SVN r10127.
easier to do event accounting that way
* greatly increase receive event and buffer sizes. We're still about half
of what Cray defaults to, so I don't feel bad about the increases
* Implement a pre-pinning optimization for eager fragments - will be
pinned on first use and left pinned for the life of the fragment
* Since we can't have two receive frag callbacks fired at the same time,
don't have receive free list - just keep one receive fragment in the
module. Saves a big free list and all that interaction.

the memory descriptor is closing itself, so that it actually works properly ;). I think I
was just getting lucky and not sending enough short messages with the reference impl.
This commit was SVN r9748.
* It appears that Cray's SeaStar has some horrible performance for iovecs - IN_pLACE
was actually slower than copying into eager frags. Ugh. And we don't even pre-pin
eager frags yet!

run-time support, as it appears to be doing bad things to memory. Update
the hack to get the local nid to match the recent TCP nal changes, and
update the P3RT api useage

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

Red Storm is complaining about invalid memory pointer (need to go back
to Linux and look at this with valgrind)
* Turn off send in place for now, so I can run the tests on RS and see if
everything else is ok
This commit was SVN r7497.
* fix dumb bug in btl_portals_get where I using the dest descriptor key instead
of the source descriptor key for the match bits, resulting in a PtlGet() with
the wrong match bits

a constructor, like the rest of the code base
- Convert usage in the tree to use the constructor to zero out an
instance of opal_output_stream_t
- Still need to re-enable output files
This commit was SVN r7253.
AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.
