lower the default priority to 0 so that it's not active unless you
specifically ask for it (this component needs more testing by people
other than me before we unleash it on the public).

- Sample in each of the three projects of how to link againt the
relevant libraries so that when components are loaded into a parent
process' space, we don't rely on the libopal/liborte/libmpi symbols
being in the parent's public symbol namespace -- instead,
dynamically link to the relevant libraries, allowing the dynamic
linker to pull those libraries in at run-time, if needed

- remove redundant OBJ_CONSTRUCT in bcast
- fix up some macros in coll_sm.h
- check to ensure that if there are too many processes in the
communicator (i.e., if we couldn't fit a flag for each of them in
the control segment), then fail selection
- setup the in_use flags properly
- adapt to new mpool API
- first working copy of reduce -- not tree-baed (but still
NUMA-aware), and only processes in order from process 0 to process
N-1 -- do not have a tree-based and/or commutative version yet
(i.e., process the results in whatever order they arrive)
Reduce now passes the new ibm reduce_big.c test. Woo hoo! Time to
declare success for the evening (and run the intel test tomorrow).

all processes call MPI_Gatherv(MPI_IN_PLACE...) because IN_PLACE is
only allowed to be used at the root. Non-root processes must use
their receive buf as the send buf.

- added relevant logic for everything except
mca_coll_basic_reduce_log_intra() -- need some help from George /
Edgar on this one...
- replaced ompi_ddt_sndrcv() with ompi_ddt_copy_content_same_ddt()
where relevant
- removed some "if (size > 1)" conditionals, because the self coll
module will always be chosen for collectives where size==1
Waiting for BA's tests to check the validity of this IN_PLACE stuff.
We'll see how it goes!

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.

- finally added "in use" flags -- one flag protects a set of segments
- these flags now used in bcast to protect (for example) when a
message is so long that the root loops around the segments and has
to re-use old segments -- now it knows that it has to wait until the
non-root processes have finished with that set of segments before it
can start using them
- implement allreduce as a reduce followed by a bcast (per discussion
with rich)
- removed some redundant data on various data structures
- implemented query MCA param ("coll_sm_shared_mem_used_data") that
tells you how much shared memory will be used for a given set of MCA
params (e.g., number of segments, etc.). For example:
ompi_info --mca coll_sm_info_num_procs 4 --param coll sm | \
grep shared_mem_used_data
tells you that for the default MCA param values (as of r7172), for 4
processes, sm will use 548864 bytes of shared memory for its data
transfer section
- remove a bunch of .c files from the Makefile.am that aren't
implemented yet (i.e., all they do is return ERR_NOT_IMPLEMENTED)
Now on to the big Altix to test that this stuff really works...
This commit was SVN r7205.
The following SVN revision numbers were found above:
r7172 --> open-mpi/ompi@bc72a7722b
- bcast now works properly for root!=0 and multi-fragment messages
- destroy mpool when communicator is destroyed
Still need to implement:
- "in use" flags for groups of fragments so that "wrapping around" in
the data segment doesn't overwrite not-yet-read data
- ensure that shared memory isn't removed before all processes have
finished with it (e.g., during COMM_FREE)
This commit was SVN r7172.
add a -I to find the included ltdl.h (vs. a system-installed ltdl.h)
- Clean up kruft in a bunch of Makefile.am's to remove now-unnecessary
AM_CPPFLAGS settings to get static-components.h for each framework
- Move the component_repository API functions out of opal/mca/base/base.h
and into opal/mca/base/mca_base_component_repository.h in order to
decrease unnecessary dependencies (e.g., before this, almost
everything in the tree depended on ltdl.h, which is unnecessary --
only a small number of files really need ltdl.h)

multiple components to share a single mpool module (e.g., the
ptl/btl and coll sm components).
- Re-tool the ptl, btl, and coll sm components to first look for the
target mpool module, and if they don't find it, to create it.
- coll sm component now correctly identifies when it is supposed to
run or not (i.e., if all the processes in the communicator are on
the same host). Now we just need to fill in some algorithms. :-)
This commit was SVN r6530.
- 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. :-)
