A mindless task for a lazy weekend: convert all the README and
README.txt files to Markdown. Paired with the slow conversion of all
of our man pages to Markdown, this gives a uniform language to the
Open MPI docs.
This commit moved a bunch of copyright headers out of the top-level
README.txt file, so I updated the relevant copyright header years in
the top-level LICENSE file to match what was removed from README.txt.
Additionally, this commit did (very) little to update the actual
content of the README files. A very small number of updates were made
for topics that I found blatently obvious while Markdown-izing the
content, but in general, I did not update content during this commit.
For example, there's still quite a bit of text about ORTE that was not
meaningfully updated.

`--enable-mem-debug` `#define`s `realloc`/`free` as macros, though macros
are also matched if they appear in references to members. Rename the
members to avoid this matching.

Add a framework to support different types of threading models including
user space thread packages such as Qthreads and argobot:
https://github.com/pmodels/argobotshttps://github.com/Qthreads/qthreads
The default threading model is pthreads. Alternate thread models are
specificed at configure time using the --with-threads=X option.
The framework is static. The theading model to use is selected at
Open MPI configure/build time.
mca/threads: implement Argobots threading layer
config: fix thread configury
- Add double quotations
- Change Argobot to Argobots
config: implement Argobots check
If the poll time is too long, MPI hangs.
This quick fix just sets it to 0, but it is not good for the
Pthreads version. Need to find a good way to abstract it.
Note that even 1 (= 1 millisecond) causes disastrous performance
degradation.
rework threads MCA framework configury
It now works more like the ompi/mca/rte configury,
modulo some edge items that are special for threading package
linking, etc.

This commit fixes an issue with the include usage in some
ompi source files. These source files are using the <> form
of include when the "" form is correct (as these are internal,
**not** system headers).

This commit contains the following changes:
The C++ bindings were removed from the standard in MPI-3.0. This
commit removes the entirety of the C++ bindings as well as the
support configury.
Removes all references to C++ from the man pages. This includes the
bindings themselves, all references to what C++ bindings return,
all not-available comments, and differences between C++ and other
language bindings.
If the user passes --enable-mpi-cxx, --enable-mpi-cxx-seek, or
--enable-cxx-exceptions, print a warning message an abort configure.

Will be replaced by PRRTE. Ensure that OMPI and OPAL layers build
without reference to ORTE. Setup opal/pmix framework to be static.
Remove support for all PMI-1 and PMI-2 libraries. Add support for
"external" pmix component as well as internal v4 one.
remove orte: misc fixes
- UCX fixes
- VPATH issue
- oshmem fixes
- remove useless definition
- Add PRRTE submodule
- Get autogen.pl to traverse PRRTE submodule
- Remove stale orcm reference
- Configure embedded PRRTE
- Correctly pass the prefix to PRRTE
- Correctly set the OMPI_WANT_PRRTE am_conditional
- Move prrte configuration to the end of OMPI's configure.ac
- Make mpirun a symlink to prun, when available
- Fix makedist with --no-orte/--no-prrte option
- Add a `--no-prrte` option which is the same as the legacy
`--no-orte` option.
- Remove embedded PMIx tarball. Replace it with new submodule
pointing to OpenPMIx master repo's master branch
- Some cleanup in PRRTE integration and add config summary entry
- Correctly set the hostname
- Fix locality
- Fix singleton operations
- Fix support for "tune" and "am" options

The opal_gethostname() function provides a more robust mechanism
to retrieve the hostname than gethostname(), which can return
results that are not null-terminated, and which can vary in its
behavior from system to system.
opal_gethostname() just returns the value in opal_process_info.nodename;
this is populated in opal_init_gethostname() inside opal_init.c.
-Changed all gethostname calls in opal subtree to opal_gethostname
-Changed all gethostname calls in orte subtree to opal_gethostname
-Changed all gethostname calls in ompi subdir to opal_gethostname
-Changed all gethostname calls in oshmem subdir to opal_gethostname
-Changed opal_if.c in test subdir to use opal_gethostname
-Changed opal_init.c to include opal_init_gethostname. This function
returns an int and directly sets opal_process_info.nodename per
jsquyres' modifications.

1) Race condition: Do not add private contexts to active list.
Private contexts are only visible to the user.
2) Recycled contexts: Destroyed contexts are put on an idle list until
finalize, continuous context creation will lead to oom condition.
Instead, check if context from idle list meets new context requirements
and reuse it.
