99144db970 Improve checkpoint/restart support by allowing a checkpoint to progress when the process is *not* in the MPI library. This involves creating a separate thread for polling for a checkpoint request. This thread is active when the MPI process is not in the MPI library, and paused when the MPI process is in the library.
Some MPI C interface files saw some spacing changes to conform to the coding standards of Open MPI.

Changed MPI C interface files to use {{{OPAL_CR_ENTER_LIBRARY()}}} and {{{OPAL_CR_EXIT_LIBRARY()}}} instead of just {{{OPAL_CR_TEST_CHECKPOINT_READY()}}}. This will allow the checkpoint/restart system more flexibility in how it is to behave.

Fixed the configure check for {{{--enable-ft-thread}}} so it has a know dependance on {{{--enable-mpi-thread}}} (and/or {{{--enable-progress-thread}}}).

Added a line for Checkpoint/Restart support to {{{ompi_info}}}.

Added some options to choose at runtime whether or not to use the checkpoint polling thread. By default, if the user asked for it to be compiled in, then it is used. But some users will want the ability to toggle its use at runtime.

There are still some places for improvement, but the feature works correctly. As always with Checkpoint/Restart, it is compiled out unless explicitly asked for at configure time. Further, if it was configured in, then it is not used unless explicitly asked for by the user at runtime.

dadca7da88 Merging in the jjhursey-ft-cr-stable branch (r13912 : HEAD).
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.

This commit was SVN r14051.

260f1fd468 Fixes trac:817
The C++ bindings were not tracking keyvals properly -- they were
freeing some internal meta data when Free_keyval() was called, not
when the keyval was actually destroyed (keyvals are refcounted in the
C layer, just like all other MPI objects, because they can live for
long after their corresponding Free call is invoked).  This commit
fixes this problem and several other things:

 * Add infrastructure on the ompi_attribute_keyval_t for an "extra"
   destructor pointer that will be invoked during the "real"
   constructor (i.e., when OBJ_RELEASE puts the refcount to 0).  This
   allows calling back into the C++ layer to release meta data
   associated with the keyval.
 * Adjust all cases where keyvals are created to pass in relevant
   destructors (NULL or the C++ destructor).
 * Do essentially the same for MPI::Comm, MPI::Win, and MPI:Datatype:
   * Move several functions out of the .cc file into the _inln.h file
     since they no longer require locks
   * Make the 4 Create_keyval() functions call a common back-end
     keyval creation function that does the Right Thing depending on
     whether C or C++ function pointers were used for the keyval
     functions.  The back-end function does not call the corresponding
     C MPI_*_create_keyval function, but rather does the work itself
     so that it can associate a "destructor" callback for the C++
     bindings for when the keyval is actually destroyed.
   * Change a few type names to be more indicative of what they are
     (mostly dealing with keyvals [not "keys"]).
 * Add the 3 missing bindings for MPI::Comm::Create_keyval().
 * Remove MPI::Comm::comm_map (and associated types) because it's no
   longer necessary in the intercepts -- it was a by-product of being
   a portable C++ bindings layer.  Now we can just query the C layer
   directly to figure out what type a communicator is.  This solves
   some logistics / callback issues, too.
 * Rename several types, variables, and fix many comments in the
   back-end C attribute implementation to make the names really
   reflect what they are (keyvals vs. attributes).  The previous names
   heavily overloaded the name "key" and were ''extremely''
   confusing.

85bb1a9c90 Add one more argument to the copy functions for the MPI objects. As this argument
is the last one on the list and as on C the caller "make it right" this addition
will not affect the way we handle the user defined copy functions. Only the C
version of the function has this additional parameter. As it represent the pointer
to the newly created MPI object It hold the key to allow us to modify the new
object (communicator, window or type) depending on some key stored on the initial
communicator.

566a050c23 Next step in the project split, mainly source code re-arranging
- 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)
