This prevents bazillions of warnings from clang tha -Wno-long-double
isn't supported.
The warning that clang issues when it see -Wno-long-double is does not
use any of the words we were looking for, so I added "unknown" to the
list of words to look for. I also re-indented the two m4 tests so
that they're a bit more readable.

Reworked ompi_info tool to be close with orte_info implementation.
ompi_info_register_types(), ompi_info_close_components() and
ompi_info_show_ompi_version() are moved to runtime/ompi_info_support.c.
Added runtime/oshmem_info_support layer that exports following api to be
used into oshmem_info tool as
oshmem_info_register_types()
oshmem_info_register_framework_params()
oshmem_info_close_components()
oshmem_info_show_oshmem_version()
These functions call ompi_info_support related interfaces as long as
Oshmem supports Open MPI/SHMEM combination.
Now orte_info/ompi_info/oshmem_info have identical implementation approach.
Possible improvement:
OSHMEM processing of --config option is the same as OMPI`s (code is duplicated).
Probably list of info_support interfaces can be extended by xxx_info_do_config().

*** THIS RFC INCLUDES A MINOR CHANGE TO THE MPI-RTE INTERFACE ***
Note: during the course of this work, it was necessary to completely separate the MPI and RTE progress engines. There were multiple places in the MPI layer where ORTE_WAIT_FOR_COMPLETION was being used. A new OMPI_WAIT_FOR_COMPLETION macro was created (defined in ompi/mca/rte/rte.h) that simply cycles across opal_progress until the provided flag becomes false. Places where the MPI layer blocked waiting for RTE to complete an event have been modified to use this macro.
***************************************************************************************
I am reissuing this RFC because of the time that has passed since its original release. Since its initial release and review, I have debugged it further to ensure it fully supports tests like loop_spawn. It therefore seems ready for merge back to the trunk. Given its prior review, I have set the timeout for one week.
The code is in https://bitbucket.org/rhc/ompi-oob2
WHAT: Rewrite of ORTE OOB
WHY: Support asynchronous progress and a host of other features
WHEN: Wed, August 21
SYNOPSIS:
The current OOB has served us well, but a number of limitations have been identified over the years. Specifically:
* it is only progressed when called via opal_progress, which can lead to hangs or recursive calls into libevent (which is not supported by that code)
* we've had issues when multiple NICs are available as the code doesn't "shift" messages between transports - thus, all nodes had to be available via the same TCP interface.
* the OOB "unloads" incoming opal_buffer_t objects during the transmission, thus preventing use of OBJ_RETAIN in the code when repeatedly sending the same message to multiple recipients
* there is no failover mechanism across NICs - if the selected NIC (or its attached switch) fails, we are forced to abort
* only one transport (i.e., component) can be "active"
The revised OOB resolves these problems:
* async progress is used for all application processes, with the progress thread blocking in the event library
* each available TCP NIC is supported by its own TCP module. The ability to asynchronously progress each module independently is provided, but not enabled by default (a runtime MCA parameter turns it "on")
* multi-address TCP NICs (e.g., a NIC with both an IPv4 and IPv6 address, or with virtual interfaces) are supported - reachability is determined by comparing the contact info for a peer against all addresses within the range covered by the address/mask pairs for the NIC.
* a message that arrives on one TCP NIC is automatically shifted to whatever NIC that is connected to the next "hop" if that peer cannot be reached by the incoming NIC. If no TCP module will reach the peer, then the OOB attempts to send the message via all other available components - if none can reach the peer, then an "error" is reported back to the RML, which then calls the errmgr for instructions.
* opal_buffer_t now conforms to standard object rules re OBJ_RETAIN as we no longer "unload" the incoming object
* NIC failure is reported to the TCP component, which then tries to resend the message across any other available TCP NIC. If that doesn't work, then the message is given back to the OOB base to try using other components. If all that fails, then the error is reported to the RML, which reports to the errmgr for instructions
* obviously from the above, multiple OOB components (e.g., TCP and UD) can be active in parallel
* the matching code has been moved to the RML (and out of the OOB/TCP component) so it is independent of transport
* routing is done by the individual OOB modules (as opposed to the RML). Thus, both routed and non-routed transports can simultaneously be active
* all blocking send/recv APIs have been removed. Everything operates asynchronously.
KNOWN LIMITATIONS:
* although provision is made for component failover as described above, the code for doing so has not been fully implemented yet. At the moment, if all connections for a given peer fail, the errmgr is notified of a "lost connection", which by default results in termination of the job if it was a lifeline
* the IPv6 code is present and compiles, but is not complete. Since the current IPv6 support in the OOB doesn't work anyway, I don't consider this a blocker
* routing is performed at the individual module level, yet the active routed component is selected on a global basis. We probably should update that to reflect that different transports may need/choose to route in different ways
* obviously, not every error path has been tested nor necessarily covered
* determining abnormal termination is more challenging than in the old code as we now potentially have multiple ways of connecting to a process. Ideally, we would declare "connection failed" when *all* transports can no longer reach the process, but that requires some additional (possibly complex) code. For now, the code replicates the old behavior only somewhat modified - i.e., if a module sees its connection fail, it checks to see if it is a lifeline. If so, it notifies the errmgr that the lifeline is lost - otherwise, it notifies the errmgr that a non-lifeline connection was lost.
* reachability is determined solely on the basis of a shared subnet address/mask - more sophisticated algorithms (e.g., the one used in the tcp btl) are required to handle routing via gateways
* the RML needs to assign sequence numbers to each message on a per-peer basis. The receiving RML will then deliver messages in order, thus preventing out-of-order messaging in the case where messages travel across different transports or a message needs to be redirected/resent due to failure of a NIC

A few changes were required to support this move:
1. the PMI component used to identify rte-related data (e.g., host name, bind level) and package them as a unit to reduce the number of PMI keys. This code was moved up to the ORTE layer as the OPAL layer has no understanding of these concepts. In addition, the component locally stored data based on process jobid/vpid - this could no longer be supported (see below for the solution).
2. the hash component was updated to use the new opal_identifier_t instead of orte_process_name_t as its index for storing data in the hash tables. Previously, we did a hash on the vpid and stored the data in a 32-bit hash table. In the revised system, we don't see a separate "vpid" field - we only have a 64-bit opaque value. The orte_process_name_t hash turned out to do nothing useful, so we now store the data in a 64-bit hash table. Preliminary tests didn't show any identifiable change in behavior or performance, but we'll have to see if a move back to the 32-bit table is required at some later time.
3. the db framework was a "select one" system. However, since the PMI component could no longer use its internal storage system, the framework has now been changed to a "select many" mode of operation. This allows the hash component to handle all internal storage, while the PMI component only handles pushing/pulling things from the PMI system. This was something we had planned for some time - when fetching data, we first check internal storage to see if we already have it, and then automatically go to the global system to look for it if we don't. Accordingly, the framework was provided with a custom query function used during "select" that lets you seperately specify the "store" and "fetch" ordering.
4. the ORTE grpcomm and ess/pmi components, and the nidmap code, were updated to work with the new db framework and to specify internal/global storage options.
No changes were made to the MPI layer, except for modifying the ORTE component of the OMPI/rte framework to support the new db framework.

that Open MPI won't even try to build the F08 bindings with older
versions of the Pathscale compilers (or any compiler that doesn't
support BIND(C) and LOGICAL parameters).

which is the same size as a Fortran or C integer. This resulted in configure
coming up with Fortran's MAX_INT as -2^31, which obviously isn't a positive
number. Since we found the MAX_INT using the same broken loop in a couple
places and doing it right is complicated, added a new macro that is much
more careful about sign roll-over.
During the Fortran rework between v1.6 and v1.7, the variable which
indicates whether or not Fortran is being compiled changed, so on platforms
without Fortran compilers, we were trying to determine the max value for
Fortran INTEGERS where we previously didn't. I believe this is why
bug #3374 appeared as a regression.
Finally, since the OMPI code doesn't cope with OMPI_FORTRAN_HANDLE_MAX
being negative (which was the root cause of the segfault in $3374),
add a check at the end of the OMPI_FORTRAN_GET_HANDLE_MAX macro to
ensure that OMPI_FORTRAN_HANDLE_MAX is always non-negative.

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.

did so!). Previously, I forgot to include the case of not specifying
--with-verbs -- oops! So now the OPAL_CHECK_VERBS_DIR macro will:
1. $opal_want_verbs will be set to: "yes" if --with-verbs or
--with-verbs=DIR was specified "no" if --without-verbs was
specified) "optional" if neither --with-verbs* nor --without-verbs
was specified
'''NOTE:''' --with-openib* are deprecated synonyms for --with-verbs*.
1. $opal_verbs_dir and $opal_verbs_libdir with either both be set or
both be empty.
This commit was SVN r26654.
* Add new configure command line options and deprecate some old ones:
* --with-verbs replaces --with-openib
* --with-verbs-libdir replaces --with-openib-libdir
* If you specify --with-openib[-libdir] without
--with-verbs[-libdir], you'll get a "these options have been
deprecated!" warning, but then they'll act just like
--with-verbs[--libdir].
'''Sidenote:''' Note that we are not renaming any components at this
time, nor are we renaming the top-level OMPI_CHECK_OPENIB m4 macro
(which is pretty strongly tied to the openib BTL and is bastaridzed
by the ofud BTL). Note that there will likely be more changes in
this area coming soon (next week?) when some long-standing changes
move to the SVN trunk: some openib BTL infrastructure will move to
ompi/mca/common, and its configury gets split up / refactored.
We extend our philosophy of other --with-<foo> configure options of
--with-verbs to ''all'' verbs-lovin components:
* If you specify --with-verbs, then all verbs-lovin' components must
configure successfully (or abort). This currently means: OOB ud,
BTL ofud, BTL openib.
* If you specify --with-verbs=DIR, then all verbs-lovin' component
must configure successfully (or abort), and will use DIR to find
verbs headers and libraries.
* If you specify --without-verbs, then all verbs-lovin' components
will be ignored.
This commit also fixes a problem where the --with-openib=DIR form
would not use DIR for ''all'' verbs-lovin' components (I think only
BTL openib and BTL ofud used that DIR). Now all of them do, as does
hwloc (because hwloc has some !OpenFabrics helper functions that
require ibv types from verbs.h).
There's a little new m4 infrastructure worth mentioning:
* If you create a new verbs-lovin' component (i.e., a component that
need verbs), your configure.m4 should
AC_REQUIRE([OPAL_CHECK_VERBS_DIR]).
* You can then use three global shell variables: $opal_want_verbs,
$opal_verbs_dir, $opal_verbs_libdir, which will be set as follows:
* opal_want_verbs will be "yes" and opal_verbs_dir and
opal_verbs_libdir will both be set to directory values, '''OR'''
* opal_want_verbs will be "no" and opal_verbs_dir and
opal_verbs_libdir will both be set empty

== More details ==
Craig Rasmussen and I have been working with the MPI-3 Fortran WG and Fortran J3 committees for a long, long time to make a prototype MPI-3 Fortran bindings implementation. We think we're at a stable enough state to bring this stuff back to the trunk, with the goal of including it in OMPI v1.7.
Special thanks go out to everyone who has been incredibly patient and helpful to us in this journey:
* Rolf Rabenseifner/HLRS (mastermind/genius behind the entire MPI-3 Fortran effort)
* The Fortran J3 committee
* Tobias Burnus/gfortran
* Tony !Goetz/Absoft
* Terry !Donte/Oracle
* ...and probably others whom I'm forgetting :-(
There's still opportunities for optimization in the mpi_f08 implementation, but by and large, it is as far along as it can be until Fortran compilers start implementing the new F08 dimension(..) syntax.
Note that gfortran is currently unsupported for the mpi_f08 module and the new mpi module. gfortran users will a) fall back to the same mpi module implementation that is in OMPI v1.5.x, and b) not get the new mpi_f08 module. The gfortran maintainers are actively working hard to add the necessary features to support both the new mpi_f08 module and the new mpi module implementations. This will take some time.
As mentioned above, ompi/mpi/f77 and ompi/mpi/f90 no longer exist. All the fortran bindings implementations have been collated under ompi/mpi/fortran; each implementation has its own subdirectory:
{{{
ompi/mpi/fortran/
base/ - glue code
mpif-h/ - what used to be ompi/mpi/f77
use-mpi-tkr/ - what used to be ompi/mpi/f90
use-mpi-ignore-tkr/ - new mpi module implementation
use-mpi-f08/ - new mpi_f08 module implementation
}}}
There's also a prototype 6-function-MPI implementation under use-mpi-f08-desc that emulates the new F08 dimension(..) syntax that isn't fully available in Fortran compilers yet. We did that to prove it to ourselves that it could be done once the compilers fully support it. This directory/implementation will likely eventually replace the use-mpi-f08 version.
Other things that were done:
* ompi_info grew a few new output fields to describe what level of Fortran support is included
* Existing Fortran examples in examples/ were renamed; new mpi_f08 examples were added
* The old Fortran MPI libraries were renamed:
* libmpi_f77 -> libmpi_mpifh
* libmpi_f90 -> libmpi_usempi
* The configury for Fortran was consolidated and significantly slimmed down. Note that the F77 env variable is now IGNORED for configure; you should only use FC. Example:
{{{
shell$ ./configure CC=icc CXX=icpc FC=ifort ...
}}}
All of this work was done in a Mercurial branch off the SVN trunk, and hosted at Bitbucket. This branch has got to be one of OMPI's longest-running branches. Its first commit was Tue Apr 07 23:01:46 2009 -0400 -- it's over 3 years old! :-) We think we've pulled in all relevant changes from the OMPI trunk (e.g., Fortran implementations of the new MPI-3 MPROBE stuff for mpif.h, use mpi, and use mpi_f08, and the recent Fujitsu Fortran patches).
I anticipate some instability when we bring this stuff into the trunk, simply because it touches a LOT of code in the MPI layer in the OMPI code base. We'll try our best to make it as pain-free as possible, but please bear with us when it is committed.

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.

* No need for OPAL_SIZEOF_BOOL and OPAL_SIZEOF_INT in comm_inln.h --
just use sizeof()
* Fix logic in ompi_setup_cxx.m4 to account for the case where we
''do'' have a C++ compiler (duh!!)
* Fix spelling error in a shell variable that ended up making a
bad/empty #define
This should bring the trunk back to being functional. Sorry for the
interruption, folks...

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.

Tests based on preprocessor CPP output, won't help either, as they
don't spit out nice computed numerical values, but rather the
#define itselve.

configure tests to find out external symbols.

Yes, friends, our favorite PCIE BTL has resurfaced as mgmt vacillates over its existence. This is an updated version that actually mostly works, in its final stages of debugging.
Some generalization still remains to be done...

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.

- 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_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...
