1. Modify the registry to eliminate redundant data copying for startup messages.
2. Revise the subscription/trigger system to avoid redundant storage of triggers and subscriptions. This dramatically reduces the search time when a registry action occurs - to illustrate the point, there are now only a handful of triggers on the system for each job. Before, there were a handful of triggers for each PROCESS in the job, all of which had to be checked every time something happened on the registry. This is much, much faster now.
3. Update all subscriptions to the new format. There are now "named" subscriptions - this allows you to "name" a subscription that all the processes will be using. The first one to hit the registry actually defines the subscription. From then on, any subsequent "subscribes" to the same name just cause that process to "attach" to the existing subscription. This keeps the number of subscriptions being tracked by the registry to a minimum, while ensuring that each process still gets notified.
4. Do the same for triggers.
Also fixed a duplicate subscription problem that was causing people to receive data equal to the number of processes times the data they should have received from a trigger/subscription. Sorry about that... :-( ...but it's all better now!
Uncovered a situation where the modex data seems to be getting entered on the registry a second time - the latter time coming after the compound command has been "fired", thereby causing all the subscriptions to fire. Asked Tim and Jeff to look into this.
Second phase of the changes will involve modifying the xcast system so that the same message gets sent to all processes. This will further reduce the message traffic, and - once we have a true "broadcast" version of xcast - really speed things up and improve scalability.

1. Fix the reigstry's overwrite logic. It was only overwriting the first keyval specified in a value - the rest were just added on regardless of whether or not the keyval already existed. This was the source of the multiple keyvals some people were seeing - should be fixed now.
2. Change the orted command parsing options so it reports options that aren't recognized - should help reduce confusion

* Add ability to completely disable libltdl (the dlopen code to load
dynamic shared objects) to configure: --disable-dlopen
* Added MCA param (component_disable_dlopen) to disable DSO loading
at runtime
* Made the event library behave in some not-completely-erroneous way
on platforms where it has absolutely no eventops support (ie, no
select, poll, or epoll)
* Disabled orte_wait, opal_few, and opal_daemon_init code on
platforms without fork, waitpid support. All non-init functions
will return OPMI_ERR_NOT_SUPPORTED
* Disable orteprobe tool when fork or pipe aren't supported

- it will now wait for the child procs to exit then kill off the daemons
- if orted is in your path it will automatically be found, or you can
specify its location.
- your LD_LIBRARY_PATH is now forwarded to the backend to make it easier to use
shared libraries in nonstandard places
Still need to work on cleanup on the backend nodes.

sockaddr_in - seems to be a good indicator)
* disable util/if code if no inet devices (again, no sockaddr_in)
* add enable/disable flag to disable stacktrace pretty-print code
(defaults to enabled). Seems there's something funky going on with
the preprocessor on Red Storm that was causing problems - this was
the easiest fix
* clean up a bunch of the configure.m4 files to remove bogus comments,
properly comment them, fix the dumb logic for happy/unhappy
* Create a macro for testing both header and library for a package,
since we seem to do this kind of test quite often. Handles the
-I and -L search paths properly (including stripping out /usr and
/usr/local if not needed)
* Converted mvapi components to configure.m4, using the nice new
ompi_check_package macro (above)

threads (basically, same as before, but we now link the right thread
libraries).
* Add disable-io-romio flag to disable compiling ROMIO
* Migrathe mvapi btl from configure.stub to configure.m4

components to succeed with --enable-dist. Instead, just add them to
all_components and make dist will still work - we're going to stamp out

frameworks, and components without configure scripts instead of
hard-coded shell variables (for projects and frameworks) and
shell variable building (for components).
* Add 3rd category of component configuration (in addition to configure
scripts and no-configured components): configure.m4 components. These
components can only be built as part of OMPI (like no-configure), but
can provide an m4 file that is run as part of the main configure
script. These macros can set whether the component should be built,
along with just about any other configuration wanted. More care must
be taken compared to configure components, as doing things like setting
variables or calling AC_MSG_ERROR now affects the top-level configure
script (so calling AC_MSG_ERROR if your component can't configure
probably isn't what you want)
* Added support to autogen.sh for the configure.m4-style components,
as well as building up the m4_define lists ompi_mca.m4 now expects
* Updated a number of macros to be more config.cache friendly (both
so that config.cache can be used and so the test can be quickly
run multiple times in the same configrue script):
- ompi_config_asm
- c_weak_symbols
- c_get_alignment
* Added new macros to be shared when configuring components:
- ompi_objc.m4 (this actually provides AC_PROG_OBJC - don't ask...)
- ompi_check_xgrid
- ompi_check_tm
- ompi_check_bproc
* Updated a number of components to use configure.m4 instead of
configure.stub
- btl portals
- io romio
- tm ras and pls
- bjs, lsf_bproc ras and bproc_seed pls
- xgrid ras and pls
- null iof (used by tm)

* mpi_show_mca_params
If set to true, this turns on the dumping of all MCA parameters when MPI_INIT is called.
Only the 'rank 0' processes will print the parameters.
* mpi_show_mca_params_file
(This value is only used if the first argument is set to true) If this value is non-NULL
it specifies the file to put the dump into. This file can then be used as input to mpirun
for debugging purposes. If this value is not set (and mpi_show_mca_params is set) then
the parameters are dumped to stdout.

- 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. :-)
