(i.e., ensure that more data items get zeroed out/set to NULL) so that
if something goes wrong during initialization, we don't try to clean
up something that isn't there (and segv).
The chance of this happening on the trunk is very low (and will also
be low once the verbs improvements are brought over to v1.7). But it
can actually happen in the v1.6 branch (e.g., if no CPC is available,
we'll try to get the length of the endpoints list, but the endpoints
list is NULL).
Hence, even though the real goal is to get this functionality over to
v1.6, I figured I'd commit to the trunk/CMR to v1.7 just to try to
keep commonality in the openib between all three where possible.

This macro is only used on the failure path so the additional if statement
should not have any affect on performance.
cmr:v1.7
This commit was SVN r28292.
- Introduced configure option '--enable-fmpi'. If configuring Open MPI w/o Fortran bindings (--disable-mpi-f77/--disable-mpi-fortran), then this option (i.e. --disable-fmpi) will be implicitly passed to the VT configure to disable MPI Fortran support.
This commit was SVN r28260.
Notes:
- This commit also eliminates the need for an available components list in use
in several frameworks. None of the code in question was making use of the
priority field of the priority component list item so these extra lists were
removed.
- Cleaned up selection code in several frameworks to sort lists using opal_list_sort.
- Cleans up the ompi/orte-info functions. Expose the functions that construct the
list of params so they can be used elsewhere.
patches for mtl/portals4 from brian
missed a few output variables in openib
This commit was SVN r28241.
Features:
- Support for an override parameter file (openmpi-mca-param-override.conf).
Variable values in this file can not be overridden by any file or environment
value.
- Support for boolean, unsigned, and unsigned long long variables.
- Support for true/false values.
- Support for enumerations on integer variables.
- Support for MPIT scope, verbosity, and binding.
- Support for command line source.
- Support for setting variable source via the environment using
OMPI_MCA_SOURCE_<var name>=source (either command or file:filename)
- Cleaner API.
- Support for variable groups (equivalent to MPIT categories).
Notes:
- Variables must be created with a backing store (char **, int *, or bool *)
that must live at least as long as the variable.
- Creating a variable with the MCA_BASE_VAR_FLAG_SETTABLE enables the use of
mca_base_var_set_value() to change the value.
- String values are duplicated when the variable is registered. It is up to
the caller to free the original value if necessary. The new value will be
freed by the mca_base_var system and must not be freed by the user.
- Variables with constant scope may not be settable.
- Variable groups (and all associated variables) are deregistered when the
component is closed or the component repository item is freed. This
prevents a segmentation fault from accessing a variable after its component
is unloaded.
- After some discussion we decided we should remove the automatic registration
of component priority variables. Few component actually made use of this
feature.
- The enumerator interface was updated to be general enough to handle
future uses of the interface.
- The code to generate ompi_info output has been moved into the MCA variable
system. See mca_base_var_dump().
opal: update core and components to mca_base_var system
orte: update core and components to mca_base_var system
ompi: update core and components to mca_base_var system
This commit also modifies the rmaps framework. The following variables were
moved from ppr and lama: rmaps_base_pernode, rmaps_base_n_pernode,
rmaps_base_n_persocket. Both lama and ppr create synonyms for these variables.
This commit was SVN r28236.
- configure:
- fixed passing FCFLAGS to the Fortran compiler when building libvt-fmpi
- temporary disabled memory allocation tracing for multi-threaded applications (introduced in v5.14.1) due to broken counter values when memory is freed in a different thread than where it was allocated
- do not build the unification library when building with HP/Platform MPI (needs linking libmpiCC, even if the C++ MPI interface isn't used)
- removed 'libfmpi' from list of MPI Fortran libraries to be searched (causes that 'libvt-fmpi' will be built when configuring for HP/Platform MPI)
- do not build the MPI Fortran library 'libvt-fmpi' when building VT inside Open MPI
- Java tracing:
- minor performance improvment: call vt_java_check_error (now vt_java_error) only if a JVMTI function returns an error
