either direct link to these basic predefined types, or a combination of them.
Anyway, the first items in the datatype list belong to OPAL, the second round
are MPI datatypes created by composing basic OPAL datatypes, and the last
batch are mapped datatype (direct correspondance between an OMPI datatype and
an OPAL one such as int -> int32_t).
Modify the op to fit this new scheme.

This is a fairly intrusive change, but outside of the moving of opal/event to opal/mca/event, the only changes involved (a) changing all calls to opal_event functions to reflect the new framework instead, and (b) ensuring that all opal_event_t objects are properly constructed since they are now true opal_objects.
Note: Shiqing has just returned from vacation and has not yet had a chance to complete the Windows integration. Thus, this commit almost certainly breaks Windows support on the trunk. However, I want this to have a chance to soak for as long as possible before I become less available a week from today (going to be at a class for 5 days, and thus will only be sparingly available) so we can find and fix any problems.
Biggest change is moving the libevent code from opal/event to a new opal/mca/event framework. This was done to make it much easier to update libevent in the future. New versions can be inserted as a new component and tested in parallel with the current version until validated, then we can remove the earlier version if we so choose. This is a statically built framework ala installdirs, so only one component will build at a time. There is no selection logic - the sole compiled component simply loads its function pointers into the opal_event struct.
I have gone thru the code base and converted all the libevent calls I could find. However, I cannot compile nor test every environment. It is therefore quite likely that errors remain in the system. Please keep an eye open for two things:
1. compile-time errors: these will be obvious as calls to the old functions (e.g., opal_evtimer_new) must be replaced by the new framework APIs (e.g., opal_event.evtimer_new)
2. run-time errors: these will likely show up as segfaults due to missing constructors on opal_event_t objects. It appears that it became a typical practice for people to "init" an opal_event_t by simply using memset to zero it out. This will no longer work - you must either OBJ_NEW or OBJ_CONSTRUCT an opal_event_t. I tried to catch these cases, but may have missed some. Believe me, you'll know when you hit it.
There is also the issue of the new libevent "no recursion" behavior. As I described on a recent email, we will have to discuss this and figure out what, if anything, we need to do.

* Update to be safe for AC 2.68 by using AC_LINK_IFELSE instead of
AC_TRY_LINK
* If enable visibility was used, ensure we fail if the compiler
doesn't support it
* Rename OMPI_CHECK_VISIBILITY -> OPAL_CHECK_VISIBILITY (and all
internal variables)

This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change.
Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation.

supports a wide variety of operating systems and platforms; see the
opal/mca/paffinity/hwloc/hwloc/README file for details.
This component includes an embedded copy of hwloc, currently based on
hwloc-1.0rc6. But note that hwloc is properly SVN imported into the
/vendor branch, so it will be easy to update when 1.0 GA is released.
Note that the hwloc tree embedded in opal/mca/paffinity/hwloc/hwloc is
identical to a hwloc distribution tarball, except that much of the
documentation was rm -rf'ed (because we don't need it for the embedded
case).
Since the paffinity framework currently does not understand hardware
threads, the hwloc component compensates for this by identifying cores
by the "first" hardware thread on that core. Hopefully we'll update
paffinity someday to understand hardware threads. :-)
configure grew a --with-hwloc option, analogous to what we do for many
other external libraries that OMPI supports. However, there's a new
feature: due to the request of several distros, OMPI can be configured
to build with its internal copy of hwloc or with an external copy of
hwloc (e.g., a system-installed hwloc).
1. If --with-hwloc is not specified, Open MPI will try to use its
internal copy (but silently fail/ignore hwloc if that fails).
1. If --with-hwloc=<dir> is supplied, Open MPI looks for hwloc
support in <dir> (and --with-hwloc-libdir=<dir>, if specified).
1. If --with-hwloc=external is supplied, Open MPI will look for hwloc
in a compiler/linker default external location.
1. If --with-hwloc=internal is supplied, Open MPI will use its
internal copy of hwloc.
Some of OMPI's main configury had to be slightly re-arranged in the
bootstrapping phase to accomodate hwloc's configry needs.

Remove the --enable-progress-threads option as this is no longer functional, and hardcode OPAL_ENABLE_PROGRESS_THREADS to 0.
Replace the --enable-mpi-threads option with --enable-mpi-thread-multiple as this is clearer as to meaning. This option automatically turns "on" opal thread support if it wasn't already so specified. If the user specifies --disable-opal-multi-threads --enable-mpi-thread-multiple, we will error out with a message
Add a new --enable-opal-multi-threads option that turns "on" opal thread support without doing anything wrt mpi-thread-multiple

use the new Automake "silent rules" if available.
If you are using an Automake prior to v1.11, you won't see the new
silent rules -- it will automatically default back to the "verbose"
rules.
Note, too, that even with these changes, you can enable the verbose
"make all" output in one of two ways:
1. Add "V=1" to your "make" command line
{{{
shell$ make all V=1
}}}
2. Add "--disable-silent-rules" to your "configure" command line:
{{{
shell$ ./configure --disable-silent-rules ...
}}}
The one down side of using the silent rules by default is that we'll
get less diagnostic information when users send their build logs. I
think we should update the web page to request that users send build
logs of "make V=1", but I'm guessing that not everyone will do it.
Note that I did ''not'' silent-ize the libltdl build (which is a dozen
or so files in the beginning of the build) because we wholly import
libltdl at autogen time. I therefore didn't want to patch libltdl
(further) after importing it a) to remain as forward- compatible as
possible, and b) patching the imported libltdl build system might be
tricky in terms of timestamps / dependencies. So those dozen-or-so
files will still be "verbose", but the rest of the files in OMPI will
be "silent".

Continue the reorganization of the configure system. Move files from the main config directory to their appropriate level-specific config directories. Modify the configure system to correctly handle compiler detection, test, and setup so that all things pertaining to opal and orte are done at the lower level, with the ompi configure system only looking at mpi-specific options.
Ensure the wrapper compilers for orte and ompi only get built when appropriate. Add support for c++ to the orte wrapper compilers, both script and non-script versions.

"TOTALVIEW" is not in the name anymore (because it applies to all
variables, not just Totalview).

Re-enable "./autogen.sh -no-ompi" again. If you -no-ompi, the entire OMPI
configury is skipped and the entire ompi/ subtree is not built. There's
some simple m4-isms that prune out the relevant parts.
I added ompi/config/, orte/config/, and opal/config/ directories. I moved a
bunch of m4 files from the top-level config/ dir into ompi/config/, and a few
into orte/config/.
Note that all 3 <project>/config directories have a config_files.m4 file. This
file contains the AC_CONFIG_FILES list for that project. The AC_CONFIG_FILES
call cannot be in an AC_DEFUN macro and conditionally called -- if it is
included at all, Autoconf will process it. Hence, these config_files.m4 files
don't AC_DEFUN -- they just have AC_CONFIG_FILES. m4_ifdef() is used to
conditionally include the files or not.
I moved a bunch of obvious OMPI-only m4 files from config/ to ompi/config/,
but I'm sure that there's more that could go. A ticket will be filed with
thoughts on future work in this area.

* No need for OPAL_SIZEOF_BOOL and OPAL_SIZEOF_INT in comm_inln.h --
just use sizeof()
* Fix logic in ompi_setup_cxx.m4 to account for the case where we
''do'' have a C++ compiler (duh!!)
* Fix spelling error in a shell variable that ended up making a
bad/empty #define

C++ compiler in configure. If we have a C++ compiler, then the MPI
C++ bindings are built by default. If we don't have a C++ compiler,
then the MPI C++ bindings are not built by default.
--enable-mpi-cxx will now force an error if there is no C++ compiler
available. --disable-mpi-cxx (or the lack of a C++ compiler) will now
disable many of the C++ compiler checks in configure.
Note that there are a few items to clean up regarding the difference
between C's _Bool type and C++'s bool type. Right now, we assume that
they are the same. But they aren't, and they shouldn't be treated as
such. This cleanup will be forced in MPI-2.2 with the introduction of
the MPI_C_BOOL MPI datatype.

OMPI
and a language agnostic part in OPAL. The convertor is completely
moved into OPAL. This offers several benefits as described in RFC
http://www.open-mpi.org/community/lists/devel/2009/07/6387.php
namely:
- Fewer basic types (int* and float* types, boolean and wchar
- Fixing naming scheme to ompi-nomenclature.
- Usability outside of the ompi-layer.
- Due to the fixed nature of simple opal types, their information is
completely
known at compile time and therefore constified
- With fewer datatypes (22), the actual sizes of bit-field types may be
reduced
from 64 to 32 bits, allowing reorganizing the opal_datatype
structure, eliminating holes and keeping data required in convertor
(upon send/recv) in one cacheline...
This has implications to the convertor-datastructure and other parts
of the code.
- Several performance tests have been run, the netpipe latency does not
change with
this patch on Linux/x86-64 on the smoky cluster.
- Extensive tests have been done to verify correctness (no new
regressions) using:
1. mpi_test_suite on linux/x86-64 using clean ompi-trunk and
ompi-ddt:
a. running both trunk and ompi-ddt resulted in no differences
(except for MPI_SHORT_INT and MPI_TYPE_MIX_LB_UB do now run
correctly).
b. with --enable-memchecker and running under valgrind (one buglet
when run with static found in test-suite, commited)
2. ibm testsuite on linux/x86-64 using clean ompi-trunk and ompi-ddt:
all passed (except for the dynamic/ tests failed!! as trunk/MTT)
3. compilation and usage of HDF5 tests on Jaguar using PGI and
PathScale compilers.
4. compilation and usage on Scicortex.
- Please note, that for the heterogeneous case, (-m32 compiled
binaries/ompi), neither
ompi-trunk, nor ompi-ddt branch would successfully launch.
