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.

bb2d0b45cd - Coverity CID37: if requests == NULL, do not deref requests[i] for
multi-completion calls. Therefore reorder tests where appropriate.
 - Always check for NULL-pointers (flag, index, completed) (yes, we
   use them in the underlying ompi_request_* functions.
 - Break early, if a NULL-request is found

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.

c7282855e7 Fixes trac:659
This commit fixes several aspects regarding MPI conformance of requests.

 * Eliminate the last argument of ompi_errhandler_request_invoke(); we
   ''always'' want to invoke the back-end exception handler with the
   real error code.
 * Make it clear in comments that we only invoke the ''first''
   exception in a given array of requests, even if there's more than
   one request with a non-MPI_SUCCESS value for MPI_ERROR.
 * Defer the freeing of requests upon exception in the back-end
   functions to MPI_WAIT* and MPI_TEST* until later; the requests are
   kept so that we know what handler to invoke when we actually invoke
   the exception.  After figuring that out, ''then'' we free requests
   with pending exceptions on them.
 * Clean up return codes from the back-end MPI_TEST* and MPI_WAIT*
   functions.
 * Slightly modify ompi_errcode_get_mpi_code() to return unity if it
   receives an MPI error code (vs. an OMPI error code).

0b2616173a Fixes trac:549
* For MPI_TEST, MPI_TESTANY, MPI_WAIT, and MPI_WAITANY (i.e., the
   TEST/WAIT functions that return up to exactly one completed
   request), return the actual error code.
 * For MPI_TESTALL, MPI_TESTSOME, MPI_WAITALL, MPI_WAITSOME, (i.e.,
   the TEST/WAIT functions that can return more than one completed
   request), return MPI_ERR_IN_STATUS.

e02114dcf3 Fixes trac:529.
* Create a new request type: NOOP (described below)
 * For all MPI_*_INIT functions, OBJ_NEW an ompi_request_t and set its
   type to NOOP
 * Ensure that the NOOP requests are OBJ_RELEASE'd when they are done
 * MPI_START looks at the request type; if NOOP, just return success. If
   not, call the PML start() function
 * MPI_STARTALL always pass the entire array of requests back to the PML
   (see next point)
 * Make the PMLs only process PML requests (i.e., ignore/skip anything
   that isn't of type PML -- such as the NOOP requests)
 * Add a little more param error checking in STARTALL

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)
