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.

Accordingly, there are new APIs to the name service to support the ability to get a job's parent, root, immediate children, and all its descendants. In addition, the terminate_job, terminate_orted, and signal_job APIs for the PLS have been modified to accept attributes that define the extent of their actions. For example, doing a "terminate_job" with an attribute of ORTE_NS_INCLUDE_DESCENDANTS will terminate the given jobid AND all jobs that descended from it.
I have tested this capability on a MacBook under rsh, Odin under SLURM, and LANL's Flash (bproc). It worked successfully on non-MPI jobs (both simple and including a spawn), and MPI jobs (again, both simple and with a spawn).
This commit was SVN r12597.
If you want to look at our launch and MPI process startup times, you can do so with two MCA params:
OMPI_MCA_orte_timing: set it to anything non-zero and you will get the launch time for different steps in the job launch procedure. The degree of detail depends on the launch environment. rsh will provide you with the average, min, and max launch time for the daemons. SLURM block launches the daemon, so you only get the time to launch the daemons and the total time to launch the job. Ditto for bproc. TM looks more like rsh. Only those four environments are currently supported - anyone interested in extending this capability to other environs is welcome to do so. In all cases, you also get the time to setup the job for launch.
OMPI_MCA_ompi_timing: set it to anything non-zero and you will get the time for mpi_init to reach the compound registry command, the time to execute that command, the time to go from our stage1 barrier to the stage2 barrier, and the time to go from the stage2 barrier to the end of mpi_init. This will be output for each process, so you'll have to compile any statistics on your own. Note: if someone develops a nice parser to do so, it would be really appreciated if you could/would share!

set to 1 or 0 instead of the user defined number or default (128).
This caused the PLS to deadlock when using '--debug-daemons' with
more than 2 processes. :(
svn blame says that it was broken in r11347
It is *not* a problem on v1.1 or v1.2 branches.
Bug spotted by Tim Mattox and myself.
This commit was SVN r11575.
The following SVN revision numbers were found above:
r11347 --> open-mpi/ompi@f52c10d18e
- use the OPAL functions for PATH and environment variables
- make all headers C++ friendly
- no unamed structures
- no implicit cast.
Plus a full implementation for the orte_wait functions.
This commit was SVN r11347.
- 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)

and path->agent_path so that it's totally clear what these are for
- make a new rsh component param for agent_param (the value from the
MCA param)
- delay the path check for the agent until the component init -- don't
make it fail during open, because the MCA base will print a warning
if a component fails open() (e.g., on clusters without rsh/ssh (!),
this component was failing noisly even though it was
normal/expected)
This commit was SVN r8596.
now take a colon-delimited list of agents (and associated argv). Also
change the default value to "ssh : rsh". Hence, if we run on a
cluster that does not have ssh, we'll fall back to rsh. If we can't
find rsh, then the rsh component will disqualify itself from
selection.

app_context:
mpirun -np 2 -prefix /path/to/ompi/on/machineA ./exec1 : \
-np 2 -prefix /path/to/ompi/on/machineB ./exec2
- Allow with -mca pls_rsh_assume_same_shell 0, the checking for the
SHELL-variable on the actual node (currently 1st node).
Sets the prefix, PATH and LD_LIBRARY_PATH for bash/ksh and
csh/tcsh.
This commit was SVN r7195.
- convert MCA params to the new API
- some style and indenting fixes
- look at local shell, and if [new] MCA param
pls_rsh_assume_same_shell is 1, then assume that the remote shell is
the same as the local shell. If pls_rsh_assume_same_shell is 0, do
a probe to figure out what the remote shell is (NOT CURRENTLY
IMPLEMENTED! you'll get a run-time warning if you set this MCA param
to 0).
- if the remote shell is not csh and not bash, then prefix the remote
command with "( ! [ -e ./.profile ] || . ./.profile;" (and suffix it
with ")") so that we run the .profile on the remote side in order to
set PATHs and the like. See the LAM FAQ for details (will someday
be on the Open MPI FAQ:
http://www.lam-mpi.org/faq/category4.php3#question8)
- add a bunch of debugging output if the MCA param pls_rsh_debug is
enabled (or the top-level debug MCA param is enabled)
- add more help messages (and corresponding calls to opal_show_help())
in help-pls-rsh.txt

- After long discussions and ruminations on how we run components in
LAM/MPI, made the decision that, by default, all components included
in Open MPI will use the version number of their parent project
(i.e., OMPI or ORTE). They are certaint free to use a different
number, but this simplification makes the common cases easy:
- components are only released when the parent project is released
- it is easy (trivial?) to distinguish which version component goes
with with version of the parent project
- removed all autogen/configure code for templating the version .h
file in components
- made all ORTE components use ORTE_*_VERSION for version numbers
- made all OMPI components use OMPI_*_VERSION for version numbers
- removed all VERSION files from components
- configure now displays OPAL, ORTE, and OMPI version numbers
- ditto for ompi_info
- right now, faking it -- OPAL and ORTE and OMPI will always have the
same version number (i.e., they all come from the same top-level
VERSION file). But this paves the way for the Great Configure
Reorganization, where, among other things, each project will have
its own version number.
So all in all, we went from a boatload of version numbers to
[effectively] three. That's pretty good. :-)
