Keep the old memchecker function as well in case of convertor is not available.

selected, but before we check whether we have been spawned. This is necessary
in order for the hierarch collective component to work. This component might
create new communicators already in MPI_Init(), which then have to execute the
dpm.mark_dyncomm function. If dpm is not initialized at that point, we
segfault.

1. applied prefix rule to functions and variables of RMAPS rank_file component
2. cleaned ompi_mpi_init.c from paffinity code
3. paffinity code moved to new opal/mca/paffinity/base/paffinity_base_service.c file
4. added opal_paffinity_slot_list mca parameter

The bug was a race condition in the barrier operation that caused the barrier in MPI_Finalize to fail on very short programs.
Scalaiblity was improved by using the daemons to aggregate modex and barrier messages before sending them to the rank=0 proc. Improvement is proportional to ppn, of course, but there really wasn't a scaling problem at low ppn anyway. This modification also paves the way for better allgather operations since now all the data for each node is sitting at the daemon level, and the daemons are now aware that a collective operation on the OOB is underway (so they -can- participate in a collective of their own to support it).
Also added better diagnostics to map out the timing associated with MPI_Init - turned on by -mca orte_timing 1.

Event var_deref_model: Variable "array_of_integers" tracked as NULL was
passed to a function that dereferences it. [model]
The arrays passed down type_get_contents may be NULL, only iff max_* is 0...
If the max_* parameter does not fit, an error is returned, anyhow.
One could improve the checks of MPI_PARAM_CHECK, but to be on the
safe side, fix in dt_args.c.

some cleanups and standardizations in the various */tools/*/

* Somewhat simplify the tool Makefile.am's
* Makes the tool Makefile.am's consistent with each other (do similar

* Update the tool Makefile.am's to remove old kruft that was required
by older versions of AM (trunk requires AM >=1.10)

still-broken trunk build on common platforms (e.g., 64 bit Linux

I'm backing out all the commits in the trunk/ompi/op tree from r17901
onwards. This code can be re-committed when compiles and runs on
common platforms.

functions that take 2 input buffers and one output buffer to avoid
some extra memory copies. These can't be used with user defined
operations. The intel c collective suite passes both original, and
new (new, not the user defined operations).

Thanks for Mohamad locating the problem, and Rainer for locating the solution.
This commit was SVN r17809.
Comm_spawn was sticking during spawn_multiple because of a problem in the dpm - the modex there is asking processes to talk to each other in an allgather_list operation, but the procs don't have the required contact info to do so. The solution here was to ensure that all parent procs have full contact info for procs in the child job.
Admittedly, this isn't the long-term answer. We would like to have the contact info given to only the parent procs that were involved in the comm_spawn. There is a way to do that, but this will suffice to keep things working until that can be implemented and tested.

The change also:
- cleans up and simplifies the command line processing code
- adds an error output if more than one hostfile passed for a single app context
- gets rid of the superfluous orte_app_context_map_t type, and instead use a simple argv of -host options

This commit was SVN r17655.
NOTE: the code provided by PANASAS includes a "switch" that they left incomplete - it doesn't cover all possibilities. Since the value being switched is an enum, this causes problems for the compiler. I added the missing values, but - since Panasas felt they could be ignored - had the switch generate an error if those cases ever occurred.
This commit was SVN r17543.
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.

* Remove from config/Makefile.am's EXTRA_DIST that which is

* Make ROMIO's configure script look for something that is actually
included in the tarball.
