This is a first cut at updating various infrastructure for git. There
will definitely be more commits; some of the scripts require
committed/pushed code (e.g., the various make-tarball scripts). So
it's not possible to know if we got it right without committing/pushing.
1. Fixes according to (http://www.open-mpi.org/community/lists/devel/2014/09/15869.php)
2. Force mpisync:rank0 to gather results. Now sync info is written by rank0 to the output file.
3. Improve mpirun_prof: 1) adopt to the environment (SLURM/TORQUE); 2) recognize some noteset-related mpirun options.

Replace our old, clunky timing setup with a much nicer one that is only available if configured with --enable-timing. Add a tool for profiling clock differences between the nodes so you can get more precise timing measurements. I'll ask Artem to update the Github wiki with full instructions on how to use this setup.

config/ directory. We split them apart a while ago in the hopes that
it would simplify things, but it didn't really (e.g., because there
were still some ompi/opal .m4 files in the top-level config/
directory, resulting in developer confusion where any given m4 macro
was defined).
So this commit consolidates them back into the top-level directory for
simplicity.
There's still (at least) two changes that would be nice to make:
1. Split any generated .m4 file (e.g., autogen-generated .m4 files)
into a separate directory somewhere so that a top-level -Iconfig/
will only get our explicitly defined macros, not the autogen stuff
(e.g., with libevent2019 needing to get the visibility macro, but
NOT all the autogen-generated inclusion of component configure.m4
files).
1. Change configure to be of the form:
{{{
# ...a small amount of preamble/setup...
OPAL_SETUP
m4_ifdef([project_orte], [ORTE_SETUP])
m4_ifdef([project_ompi], [OMPI_SETUP])
# ...a small amount of finishing stuff...
}}}
I doubt we'll ever get anything as clean as that, but that would be
the goal to shoot for.

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.

NOTE: the IPv6 support is currently marginally working and has problems when IPv6 headers are present but the interfaces are not configured to use that protocol, per several reports from users. It is unclear that anyone is willing/able to support this capability. Should that situation change, this change can be reconsidered.

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.

well..)
- As Jeff suggested, for m4 macros, dont use _ OPAL, but
rather OPAL_ prefix
- Set the variable before AC_SUBST, so that replacement happens
in f77 header-file, too.

MPI_MAX_PROCESSOR_NAME
MPI_MAX_ERROR_STRING
MPI_MAX_OBJECT_NAME
MPI_MAX_INFO_KEY
MPI_MAX_INFO_VAL
MPI_MAX_PORT_NAME
MPI_MAX_DATAREP_STRING
Defaults stay as theyr currently are -- and now give an explanation on the
min/max values being used in a central place...
m4-macro _OPAL_WITH_OPTION_MIN_MAX_VALUE may be benefical in other parts
of the configure system.
- We need some of these in the lower level OPAL for an upcoming commit!
All other levels base their values on them.

functionality (per MPI-2.1). This warning can be toggled using
--enable-mpi-interface-warning (default OFF), but can be
selectively turned on passing
mpicc -DOMPI_WANT_MPI_INTERFACE_WARNING
Using icc, gcc < 4.5, warnings (such as in mpi2basic_tests) show:
type_vector.c:83: warning: ‘MPI_Type_hvector’ is deprecated
(declared at /home/../usr/include/mpi.h:1379)
Using gcc-4.5 (gcc-svn) these show up as:
type_vector.c:83: warning: ‘MPI_Type_hvector’ is deprecated
(declared at /home/../usr/include/mpi.h:1379):
MPI_Type_hvector is superseded by MPI_Type_create_hvector in MPI-2.0
Jeff and I propose to turn such warnings on with Open MPI-1.7 by default.
- Detection of user-level compiler is handled using the preprocessor
checks of GASnet's other/portable_platform.h (thanks to Paul Hargrove
and Dan Bonachea) adapted into ompi/include/mpi_portable_platform.h
(see comments).
The OMPI-build time detection is output (Familyname and Version)
with ompi_info.
This functionality (actually any upcoming __attribute__) are turned
off, if a different compiler (and version) is being detected.
- Note, that any warnings regarding (user-compiler!=build-compiler)
as discussed in the RFC are _not_ included for now.
- Tested on Linux with --enable-mpi-interface-warning on
Linux, gcc-4.5 (deprecated w/ specific msg)
Linux, gcc-4.3 (deprecated w/o specific msg)
Linux, pathscale 3.1 (deprecated w/o specific msg)
Linux, icc-11.0 (deprecated w/o specific msg)
Linux, PGI-8.0.6 accepts __deprecated__ but does not issue a warning,
further investigation needed...
