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.

The following SVN revision numbers were found above:
r21330 --> open-mpi/ompi@95596d1814
into the OPAL namespace, eliminating cases like opal/util/arch.c
testing for ompi_fortran_logical_t.
As this is processor- and compiler-related information
(e.g. does the compiler/architecture support REAL*16)
this should have been on the OPAL layer.
- Unifies f77 code using MPI_Flogical instead of opal_fortran_logical_t
- Tested locally (Linux/x86-64) with mpich and intel testsuite
but would like to get this week-ends MTT output
- PLEASE NOTE: configure-internal macro-names and
ompi_cv_ variables have not been changed, so that
external platform (not in contrib/) files still work.

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...

- Any $ac_cv-variable does not need to be converted into strings
before checking
- That's funny: The check for ac_cv_sizeof_int =... always was wrong.
We have to DEREF $ac_cv_sizeof_int, dollar missing.
We always ran on arches, where MPI_OFFSET_TYPE=long was selected...
- Overly long lines should be split into several AC_MSG_WARN.

Also, per chat with Jeff, modified the Makefile.am's of a few orte tools so that they were consistent in the way we generate the ompi-equivalent cmds.
This commit was SVN r20165.
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.

* Use the (undocumented) `solaris_use_stlport4` libtool variable to
turn off any Cstd/stlport4 linkage. This allows Open MPI to be C++
STL agnostic.
* Patch `config/libtool.m4` in autogen.sh for a bug in Libtool's
detection of the Sun Studio Fortran compiler. See the below e-mail
thread for more details:
http://www.open-mpi.org/community/lists/devel/2008/11/4920.php
This commit was SVN r20036.
* Add OMPI_F77_CHECK_REAL16_C_EQUV test whether REAL*16 is bit
equivalent to long double. AC_DEFINE OMPI_REAL16_MATCHES_C with
result (0 or 1).
* Update ompi_info to only show real16 support if
OMPI_REAL16_MATCHES_C is 1.
* Update DDT to only support REAL16 and COMPLEX32 if
1==OMPI_REAL16_MATCHES_C.
* MPI Op function pointer tabls will have NULL for the REAL16 and
COMPLEX32 entries if 0==OMPI_REAL16_MATCHES_C.
* Slightly cleaned up OMPI_F77_GET_ALIGNMENT and OMPI_F77_CHECK m4
tests (use OMPI_VAR_SCOPE_PUSH/POP).

1. completely and cleanly separates responsibilities between the HNP, orted, and tool components.
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"
This is not intended for the 1.3 release as it is a major change requiring considerable soak time.

Don't include it in LIBS if it doesn't actually contain the symboles we're

* Make the results of the top-level configure.ac test for
_SC_NPROCESSORS_ONLN be cached so that we can check for it
elsewhere (e.g., opal/mca/paffinity/posix/configure.m4)
* Update top-level configure.ac test for _SC_NPROCESSORS_ONLN: stamp
out another AC_TRY_COMPILE
* Ensure paffinity:posix doesn't even try to compile if we don't
have _SC_NPROCESSORS_ONLN
* Minor style updates

methods (in order of precedence):
1. #pragma ident <ident string> (e.g., Intel and Sun)
1. #ident <ident string> (e.g., GCC)
1. static const char ident[] = <ident string> (all others)
By default, the ident string used is the standard Open MPI version string. Only
the following libraries will get the embedded version strings (e.g., DSOs will
not):
* libmpi.so
* libmpi_cxx.so
* libmpi_f77.so
* libopen-pal.so
* libopen-rte.so
* Added two new configure options:
* `--with-package-name="STRING"` (defaults to "Open MPI username@hostname
Distribution"). `STRING` is displayed by `ompi_info` next to the "Package"
heading.
* `--with-ident-string="STRING"` (defaults to the standard Open MPI version
string - e.g., X.Y.Zr######). `%VERSION%` will expand to the Open MPI
version string if it is supplied to this configure option.

with Libtool 2.1a versions prior to the lt_dladvise code. Autogen
tries to figure out which version you're on, so either will now work with
the trunk.
