- Add signal handler BLCR register (helps with debugging)
- ifdef out the cr_request_file section for checkpointing self.
There is a bug with the 0.4.2 version of BLCR such that this
does not handle moving checkpoint files around.
I'm following up with the BLCR folks on this one (and checking
the newest release).
This commit was SVN r14069.
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.

builds, so disable it there
* On 10.4.8 (and possibly others), siginfo is NULL in the signal
callback on 64 bit Intel builds, so account for that in the signal
callback.

- mca_base_param_file_prefix
(Default: NULL)
This is the fullname of the "-am" mpirun option. Used to specify a ':'
separated list of AMCA parameter set files.
- mca_base_param_file_path
(Default: $SYSCONFDIR/amca-param-sets/:$CWD)
The path to search for AMCA files with relative paths. A warning will be
printed if the AMCA file cannot be found.
* Added a new function "mca_base_param_recache_files" the re-reads the file
configurations. This is used internally to help bootstrap the MCA system.
* Added a new orterun/mpirun command line option '-am' that aliases for the
mca_base_param_file_prefix MCA parameter
* Exposed the opal_path_access function as it is generally useful in other
places in the code.
* New function "opal_cmd_line_make_opt_mca" which will allow you to append a
new command line option with MCA parameter identifiers to set at the same
time. Previously this could only be done at command line declaration time.
* Added a new directory under the $pkgdatadir named "amca-param-sets" where all
the 'shipped with' Open MPI AMCA parameter sets are placed. This is the first
place to search for AMCA sets with relative paths.
* An example.conf AMCA parameter set file is located in
contrib/amca-param-sets/.
* Jeff Squyres contributed an OpenIB AMCA set for benchmarking.
Note: You will need to autogen with this commit as it adds a configure param.
Sorry :(

The following Trac tickets were found above:
Ticket 590 --> https://svn.open-mpi.org/trac/ompi/ticket/590
* Have darwin backtrace code return an error when buffer() is
called, since it is not imnplemented
* Print out hostname & pid when giving signal information
* If backtrace_buffer() is implemented, use that instead of
backtrace_print() and prefix stacktrace with the hostname
* Make the signal information printed be more user friendly
* If we're using the backtrace_buffer() code, don't print
the last two functions (which will be show_stackframe()
then backtrace_buffer()) so that users won't keep thinking
the error occurred inside Open MPI (sneaky, yes...)

are passed to the component (especially -m64)
* Properly open / close the component. This isn't strictly necessary
to fix the bug, but was an oversight that should be fixed.

* Use $31 instead of mnemonic zero for the gcc inline
assembly test, as the GNU assembler doesn't like
zero, but both Tru64 and GNU assembler should be fine
with $31
* Disable Linux timer component on Alpha. The CPU timer
rolls over every 10 seconds or less, so it's kinda
worthless for our needs.
* Fix some escaping issues when local functions are
denoted with a $
* Remove C++ comments from the Alpha assembly.
* Add base assembly code for the non-inlined functions
on Alpha

have to get the {PROJECT}_DECLSPEC in front of the prototype.

range of OS friendly path management functions, such as opal_basename
opal_dirname. They should always be used instead of basename and

that are compatible with the OS.
The OPAL_ENV_SEP define should be used (instead of ':') when a env
variable is splitted.

the code is just plain wrong).
