It is essential to call mca_base_framework_close for every framework
that is opened. coll/ml was not doing this so neither bcol nor sbgp
were getting cleaned up. This commit fixes this omission.
Also fixed a leak caused by calling OBJ_DESTRUCT for something created
with OBJ_NEW. With these changes coll/ml appears to be valgrind clean.
cmr=v1.8.2:reviewer=manjugv
This commit was SVN r31743.
The error doesn't prevent the user from running so there is no reason
to display it unless the user requested it (through coll_ml_verbose).
cmr=v1.8:reviewer=jsquyres
This commit was SVN r31242.
Also fixed spelling: IS_NOT_RECHABLE -> IS_NOT_REACHABLE.
Also mark a few places where opal_show_help() should have been used;
Manju will take care of these.
This commit was SVN r31104.
This is hot-fix patch for the issue reported by Ralph.
In future we plan to restructure ml data structure layout.
Tested by Nathan.
cmr=v1.7.5:ticket=trac:4158
This commit was SVN r30619.
The following Trac tickets were found above:
Ticket 4158 --> https://svn.open-mpi.org/trac/ompi/ticket/4158
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().

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.
The project includes following components and frameworks:
- ML Collective component
- NETPATTERNS and COMMPATTERNS common components
- BCOL framework
- SBGP framework
Note: By default the ML collective component is disabled. In order to enable
new collectives user should bump up the priority of ml component (coll_ml_priority)
