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

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.

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.

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.

1. minor modification to include two new opal MCA params:
(a) opal_profile: outputs what components were selected by each framework
currently enabled for most, but not all, frameworks
(b) opal_profile_file: name of file that contains profile info required
for modex
2. introduction of two new tools:
(a) ompi-probe: MPI process that simply calls MPI_Init/Finalize with
opal_profile set. Also reports back the rml IP address for all
interfaces on the node
(b) ompi-profiler: uses ompi-probe to create the profile_file, also
reports out a summary of what framework components are actually
being used to help with configuration options
3. modification of the grpcomm basic component to utilize the
profile file in place of the modex where possible
4. modification of orterun so it properly sees opal mca params and
handles opal_profile correctly to ensure we don't get its profile
5. similar mod to orted as for orterun
6. addition of new test that calls orte_init followed by calls to
grpcomm.barrier
This is all completely benign unless actively selected. At the moment, it only supports modex-less launch for openib-based systems. Minor mod to the TCP btl would be required to enable it as well, if people are interested. Similarly, anyone interested in enabling other BTL's for modex-less operation should let me know and I'll give you the magic details.
This seems to significantly improve scalability provided the file can be locally located on the nodes. I'm looking at an alternative means of disseminating the info (perhaps in launch message) as an option for removing that constraint.

2. removes all wireup messaging during launch and shutdown.
3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol.
4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0.
5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none".
6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout.
7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output"

Cleanup ALL instances of output involving the printing of orte_process_name_t structures using the ORTE_NAME_ARGS macro so that the number of fields and type of data match. Replace those values with a new macro/function pair ORTE_NAME_PRINT that outputs a string (using the new thread safe data capability) so that any future changes to the printing of those structures can be accomplished with a change to a single point.
Note that I could not possibly find outputs that directly print the orte_process_name_t fields, but only dealt with those that used ORTE_NAME_ARGS. Hence, you may still have a few outputs that bark during compilation. Also, I could only verify those that fall within environments I can compile on, so other environments may yield some minor warnings.

It solve the problem with the MPI_Aint alignment that showed up on Solaris
Sparc and on heterogeneous environments when dealing with the data-type description.
The solution is to move the displacement array from the packed array if we
detect that the local architecture required MPI_Aint to be aligned to an
MPI_Aint boundary (which is not the case for x86 architectures if MPI_Aint
is a 64 bits type).

Sorry :(
This commit was SVN r13867.
- Set ompi-specific autoconf cache-variables
- Implement one function to check for availability of an
attribute with the possibility for a cross-check.
- Do cross-checks for
__attribute__(format)
__attribute__(nonnull)
__attribute__(sentinel)
__attribute__(warn_unused_result)
- Grep the compilers warnings for keywords regarding ignored
attributes.
- Include also the no_instrument_function
This commit was SVN r13556.
Add new function opal_get_num_processors() that will return the number
of processors on the local host. Does the Right thing in POSIX
environments (to include a special case for OS X), and will shortly do
the Right Thing for Windows (this commit includes a change to
configure, so I wanted to get that in before the US workday -- the
Windows code can some shortly because it won't involve configury
changes).

remote nodes. It will also kill off rogue orteds and orterun
processes. The killing of processes is ifdef'ed out for Windows
since I do not know how to do it there. Note that this change
will requite an autogen.

Sorry for the configure change -- hopefully it's early enough in the
morning that it won't affect people... (new approach won't have a
configure change).
