- 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.
Other changes:
1. Remove the old xcpu components as they are not functional.
2. Fix a "bug" in orterun whereby we called dump_aborted_procs even when we normally terminated. There is still some kind of bug in this procedure, however, as we appear to be calling the orterun job_state_callback function every time a process terminates (instead of only once when they have all terminated). I'll continue digging into that one.
This will require an autogen/configure, I'm afraid.
This commit was SVN r11228.
Clean up the remainder of the size_t references in the runtime itself. Convert to orte_std_cntr_t wherever it makes sense (only avoid those places where the actual memory size is referenced).
Remove the obsolete oob barrier function (we actually obsoleted it a long time ago - just never bothered to clean it up).
I have done my best to go through all the components and catch everything, even if I couldn't test compile them since I wasn't on that type of system. Still, I cannot guarantee that problems won't show up when you test this on specific systems. Usually, these will just show as "warning: comparison between signed and unsigned" notes which are easily fixed (just change a size_t to orte_std_cntr_t).
In some places, people didn't use size_t, but instead used some other variant (e.g., I found several places with uint32_t). I tried to catch all of them, but...
Once we get all the instances caught and fixed, this should once and for all resolve many of the heterogeneity problems.
This commit was SVN r11204.
Added another system-level test function for ORTE that just spins until terminated by a ctrl-c signal.
Modified orterun - added a couple of newlines to the output when abnormally terminating so the prompt always is on a new line.

* num_children should really be an int instead of size_t
since 'size_t' is not signed and num_children can (in rare cases)
drop below 0, and don't want it to roll around to MAX_INT or some
such.
* I figured out that this problem only happened to me because I use
the pls_fork_reap_timeout MCA parameter and thus the only time that
the code in pls_fork_module.c to waitpid is executed is if this is
not set to 0 (I had it set to 1 to give my procs time to exit). I
adjusted the loop from while{...} to do{...}while; so that it is
executed at least once for consistency.
* de-register the SIGCHILD callback for the pid before we attempt
to kill it, so that we don't leave the door open for both the
waitpids (the one in the callback, and the one in this function)
to race to see who can wait on the child.
* Move the 'thread release' to outside the for loop for a bit of an
optimization, and always set the value to 0 since we want to
finish after this function.
* Added a help message for the case when we can't send a kill()
signal to the process. Should never happen, but all is possible
in the wild wild west of HPC.
This commit was SVN r10666.
When we force an application to terminate (via CTRL-C to mpirun)
we send an out-of-band message to the orted to reap its children.
the fork PLS was doing an internal waitpid but never releasing or
updating the information and signaling the condition variable. So
the fork PLS callback for SIGCHLD registered with the event library
and this waitpid are in a bit of a race to 'waitpid' for the children.
Since the PLS callback was the only one that handled the signal properly
when it 'won' then things were great -- as in the normal termination case.
But when it 'lost' -- as in the abnormal termination case -- the orted
never received the proper signal that its children had gone away.
We want to preserve the internal fork PLS callback since it allows
for a timeout while waiting for the child, which the event library
won't do.
This allows both to exist, and behave properly.
This was introduced in r9068.
The ticket is still open since the orted's hang in other situations
still. This is a fix for one of the causes.
This commit was SVN r10662.
The following SVN revision numbers were found above:
r9068 --> open-mpi/ompi@c2c2daa966
1. Changed the RMGR and PLS APIs to add "signal_job" and "signal_proc" entry points. Only the "signal_job" entries are implemented - none of the components have implementations for "signal_proc" at this time. Thus, you can signal all of the procs in a job, but cannot currently signal only one specific proc.
2. Implemented those new API functions in all components except xgrid (Brian will do so very soon). Only the rsh/ssh and fork modules have been tested, however, and only under OS-X.
3. Added signal traps and callback functions for SIGUSR1/2 to orterun/mpirun that catch those signals and call the appropriate commands to propagate them out to all processes in the job.
4. Added a new test directory under the orte branch to (eventually) hold unit and system level tests for just the run-time. Since our test branch of the repository is under restricted access, people working on the RTE were continually developing their own system-level tests - thus making it hard to help diagnose problems. I have moved the more commonly-used functions here, and added one specifically for testing the SIGUSR1/2 functionality.
I will be contacting people directly to seek help with testing the changes on more environments. Other than compile issues, you should see absolutely no change in behavior on any of your systems - this additional functionality is transparent to anyone who does not issue a SIGUSR1/2 to mpirun.

argv[0] and the cwd on the target node (i.e., the node where the
executable will be running in all systems except BProc, where the
searches are run on the node where orterun is invoked).
- fork pls now does cwd and argv[0] search in orted
- bproc pls does cwd and argv[0] search in orterun
- cwd behavior slightly different:
- if user specifies a -wdir to orterun, we chdir() to there; if we
can't for some reason, abort
- if user does not specify a -wdir, try to chdir() to the dir where
orterun was invoked. If we can't for some reason (e.g., it
doesn't exist on the target node), then try to chdir($HOME). If
we can't do that, then just live with whatever default directory
we were put in.

- 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)
This commit was SVN r8985.
If you use --prefix and then "-x LD_LIBRARY_PATH", the rsh pls would
take great pains to ensure that PATH and LD_LIBRARY_PATH were setup
correctly on the local and remote nodes, but then the fork pls would
blitely overwrite LD_LIBRARY_PATH with what the user exported (i.e.,
most likely without our prefix). This patch takes care of that -- the
fork pls examines the incoming environment, and if it sees PATH or
LD_LIBRARY_PATH, it re-prefixes those variables.

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

tree.
- fix up #include's throughout the tree (yay contrib/search_replace.pl!)
- remove a few extraneous #include's
- remove orte_sys_info*() from opal_init()/opal_finalize() (it's
already in orte_init_stage1() and orte_system_finalize())
- remove dependencies in opal on orte_system_info -- util/os_path.c
and util/os_create_dirpath.c (they only used path_sep, anyway --
easily changed to #defines)

against the total number of processors. If not oversubscribing, emit
the MCA environment variable mpi_paffinity_processor with the
processor number to bind the process to. This parameter is picked up
during MPI_Init (i.e., ompi_mpi_init()) and used to bind the process,
but currently iif the MCA param mpi_paffinity_alone is set to a
nonzero value (i.e., the user asks for it).

test from orte_init_stage1 into a new framework, Startup Discovery Service
(sds). This allows us to have more flexibility with platforms like
Red Storm, which do not have a universe in the usual meaning and don't have
a seed daemon they can contact
This commit was SVN r6630.
- 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. :-)
