- My original patch stands: MPI_FINALIZE directly invokes the
attribute callbacks on MPI_COMM_SELF
- We added some user-level checks to ensure that they don't call
MPI_FINALIZE twice (this isn't really required, but it will prevent
whacky segv's -- they'll at least get a nice error message)
- Removed the attribute callbacks on MPI_COMM_SELF from
ompi_mpi_comm_finalize (i.e., we just moved them from
ompi_mpi_comm_finalize to ompi_mpi_finalize -- we just moved this
process up earlier in the MPI_FINALIZE sequence of events)
- Because there were so many conversations about this, here's the
rationale:
- MPI-2:4.8 says that we have to MPI_COMM_FREE MPI_COMM_SELF so that
the attribute callbacks are invoked.
- After considerable discussion, we came to the conclusion that
FREE'ing COMM_SELF is not the issue -- calling the callbacks is
the issue.
- So it is sufficent for MPI_FINALIZE to directly invoke these
attribute callbacks
- The attribute callbacks are *not* invoked on other communicators
because said communicators are not MPI_COMM_FREE'ed

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

comm_fill_rest there is no need for calling ompi_set_group_rank, since
we know already the rank of the process in the new comm. In case the
process was not part of the new communicator (rank = MPI_UNDEFINED)
calling this function caused a segfault on some platforms.

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

Ensure that only processes who will be in the new communicator call
the coll selection function. It is pointless (and Bad in some cases)
for processes who are not in the new communicator to try to select a
coll module for the new communicator.

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.
