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MPI_Type_hvector is superseded by MPI_Type_create_hvector in MPI-2.0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...

linker option when there is no visibility attribute support thus no visible
external variables. This is to get around a Sun Studio compiler version that
doesn't recognize the visibility attribute but recognizes the -xldscope option.

Add two new configure options that specify:
1. when to add padding to the openib control header - this *only* happens when the configure option is specified
2. when to use the dr-like checksum as opposed to the memcpy checksum. Not selectable at runtime - to eliminate performance impacts, this is a configure-only option
Also removed an unused checksum version from opal/util/crc.h.
The new component still needs a little cleanup and some sync with recent ob1 bug fixes. It was created as a separate module to avoid performance hits in ob1 itself, though most of the code is duplicative. The component is only selectable by either specifying it directly, or configuring with the dr-like checksum -and- setting -mca pml_csum_enable_checksum 1.
Modify the LANL platform files to take advantage of the new module.

This macro is a wrapper around OMPI_SETUP_PACKAGE, and provides common
functionality that I found myself doing in multiple components.
Someone may want to convince me that we should just wrap this all in
OMPI_SETUP_PACKAGE, but I did it first as a separate macro because so
many other places are already using OMPI_SETUP_PACKAGE and I didn't
want to update all of them.
This macro does the following:
* Assumes that this component should be built by default if all
headers and libraries can be found
* Adds --with-<name> and --with-<name>-libdir options to configure
* Sanity checks directory names given to the above options (i.e., look
for a token file in each, but only if the directory argument is
given)
* Assumes that if --with-<name> is supplied and we can't build the
component, it's a fatal error.
* Assumes that if --with-<name> is NOT supplied and we can't build the
component, it's NOT a fatal error.
* Run OMPI_CHECK_PACKAGE (check for the specific presence of header
files and/or libraries) to determine if the package is available
* Set <framework>_<component>_WRAPPER_EXTRA_LDFLAGS
* Set <framework>_<component>_WRAPPER_EXTRA_LIBS
* Set and AC_SUBST <framework>_<component>_CPPFLAGS
* Set and AC_SUBST <framework>_<component>_CFLAGS
* Set and AC_SUBST <framework>_<component>_LDFLAGS
* Set and AC_SUBST <framework>_<component>_LIBS

However, there is a bug in the config/ompi_check_pcie.m4 that I found this morning which causes those components to always attempt to build. This fixes it so the trunk will build again.

* Significantly improve the check to see if REAL*16 === the back-end
C type (i.e., not just in size, but also in representation)
* Add a check to see if Intel compiler's _Quad type === REAL*16
* Ensure that on the Sun SPARC with the Sun compilers, we get long
double === REAL*16

explicitly specified. This bug has escaped for a long time because
OMPI_CHECK_WITHDIR wasn't working properly until recently (r20289);
the fact that the wrong header file was specified was irrelevant
because OMPI_CHECK_WITHDIR was broken and the wrong header filename
was effectively ignored.

If someone specifies a directory for a config option, then we should respect that designation and error out if the directory isn't found. Implemented first for the --with-openib options.

* 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:

* 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).

<infiniband/driver.h> cannot be included because it will fail to
compile. So per advice from Roland, in that case, just put manually
include the one ibv_*() prototype that we need. Use an undocumented
feature of AC_CHECK_HEADERS to check for <infiniband/driver.h> that I
was told on the autoconf mailing list (see the comment for more
details).

I copied the config directory in another location, and the original
.svn directory was replaced by the Open MPI one ... As a result my
first commit, applied the changes on the Open MPI trunk instead of
the other project.

compilers as well. Not doing this was causing problems with
MPI::ERRORS_THROW_EXCEPTIONS with gcc in 32 bit (but not 64 bit!).
* Ensure that the C and Fortran compilers actually like the C++
exceptions flags. If not, currently just abort. Let's see if
anyone complains about this -- I doubt they will because a) C++
exception support is not enabled by default, and b) I think C++
exceptions really only make sense within the same compiler family.

Commit from a long-standing Mercurial tree that ended up incorporating a lot of things:
* A few fixes for CPC interface changes in all the CPCs
* Attempts (but not yet finished) to fix shutdown problems in the IB CM CPC
* #1319: add CTS support (i.e., initiator guarantees to send first message; automatically activated for iWARP over the RDMA CM CPC)
* Some variable and function renamings to make this be generic (e.g., alloc_credit_frag became alloc_control_frag)
* CPCs no longer post receive buffers; they only post a single receive buffer for the CTS if they use CTS. Instead, the main BTL now posts the main sets of receive buffers.
* CPCs allocate a CTS buffer only if they're about to make a connection
* RDMA CM improvements:
* Use threaded mode openib fd monitoring to wait for for RDMA CM events
* Synchronize endpoint finalization and disconnection between main thread and service thread to avoid/fix some race conditions
* Converted several structs to be OBJs so that we can use reference counting to know when to invoke destructors
* Make some new OBJ's have opal_list_item_t's as their base, thereby eliminating the need for the local list_item_t type
* Renamed many variables to be internally consistent
* Centralize the decision in an inline function as to whether this process or the remote process is supposed to be the initiator
* Add oodles of OPAL_OUTPUT statements for debugging (hard-wired to output stream -1; to be activated by developers if they want/need them)
* Use rdma_create_qp() instead of ibv_create_qp()
* openib fd monitoring improvements:
* Renamed a bunch of functions and variables to be a little more obvious as to their true function
* Use pipes to communicate between main thread and service thread
* Add ability for main thread to invoke a function back on the service thread
* Ensure to set initiator_depth and responder_resources properly, but putting max_qp_rd_ataom and ma_qp_init_rd_atom in the modex (see rdma_connect(3))
* Ensure to set the source IP address in rdma_resolve() to ensure that we select the correct OpenFabrics source port
* Make new MCA param: openib_btl_connect_rdmacm_resolve_timeout
* Other improvements:
* btl_openib_device_type MCA param: can be "iw" or "ib" or "all" (or "infiniband" or "iwarp")
* Somewhat improved error handling
* Bunches of spelling fixes in comments, VERBOSE, and OUTPUT statements
* Oodles of little coding style fixes
* Changed shutdown ordering of btl; the device is now an OBJ with ref counting for destruction
* Added some more show_help error messages
* Change configury to only build IBCM / RDMACM if we have threads (because we need a progress thread)
