new flag to ompi_info that allows a user to print all MCA variables of a specific type.
--type version_string
This command will print all MCA variables of type version_string.

mpirun ... -x env_foo1=val1 -x env_foo2 -x env_foo3=val3 should now be expressed as
mpirun ... -mca mca_base_env_list env_foo1=val1+env_foo2+env_foo3=val3.
The motivation for doing this is so that a list of environment variables may be set via standard MCA mechanisms such as mca parameter files, amca lists, etc.

After discussion with Nathan, change the ERR_VALUE_OUT_OF_BOUNDS to be
ERR_NOT_FOUND, for two reasons:
1. It's consistent with other uses of ERR_NOT_FOUND in the code.
1. In this case, we could have just looked up a variable that is
basically a "hole" -- e.g., var indexes 0, 1, 2 are valid, and 4,
5, and 5 are valid, but 3 is invalid (e.g., 3 was de-registered --
remember that MPI_T explicitly does not allow re-using indexes).
So returning ERR_OUT_OF_BOUNDS seems weird -- returning
ERR_NOT_FOUND seems a bit more natural.

This commit was SVN r32158.
The following Trac tickets were found above:
Ticket 4587 --> https://svn.open-mpi.org/trac/ompi/ticket/4587
Several fixes:
- I was allowing an MPI_T_cvar_handle to be created for an invalid
variable. Fixed this by checking if the variable is valid in
mca_base_var_get.
- Use a better error code when the caller tries to create an unbound
pvar handle for a bound variable.
- Return the verbosity level in MPI_T_cvar_get_info.

The original code was passing a union by value, and doing odd things
on Solaris/SPARC (where "odd" rhymes with "SIGBUS"). Replace it with
an exploded switch/case block for all the enum values. Also use the
string literals so that we get compiler checking of the format string
vs. the type of the actual arguments.

- Change all instances of index -> vari to avoid issues with redefining index.

This commit was SVN r29997.
This commit adds an API for registering and querying performance
variables (mca_base_pvar) in the MCA base. The existing MCA variable
system API has been updated to reflect the new API: MCA variable
groups have performance variables, and new types have been added (double,
unsigned long long) to reflect what is required by the MPI_T
interface. Additionally, the MCA variable group code has been split
into its own set of files: mca_base_var_group.[ch].
Details of the new API can be found in doxygen comments in the header:
mca_base_pvar.h.
Other changes to the variable system:
- Use an opal_hash_table to speed up variable/group lookup.
- Clean up code associated with MCA variable types.
- Registered performance variables are printed by ompi_info -a. In the
future an option should be added to control this behavior.
Changes to OMPI:
- Added full support for the MPI_T performance variable interface.
This commit was SVN r28800.
Add an option to ompi_info (-l, --level) that takes a number in the
interval (1,9). Only MCA variables up to this level will be printed.
The default level is 1.
Print the level as part of both the parsable and readable output.
This commit was SVN r28750.
Other changes:
- Added a flag to the MCA variable system to indicate a variable should go away
when its group does. Both mca_base_framework_var_register() and
mca_base_component_var_register() set this flag.
Notes:
- mca_base_components_open is deprecated. It will be removed in a future commit.
- All frameworks should use MCA_BASE_FRAMEWORK_DECLARE to declare their
framework structure.
- All calls to framework open/close functions should be changed to use the
mca_base_framework_* functions.
- Instead of special-casing installdirs a flag was added to prevent calling
into the variable system when opening a framework.
- Ralph: Clarify the functional definition of the "register" function in the
MCA framework object - it had the same name as another function that does a
totally different thing.
- As per discussion with Ralph the behavior of mca_base_framework_register()
is to always call mca_base_framework_components_register() if the framework's
register function was successful. This removed the need for frameworks to
have to call this function directly.
This commit was SVN r28237.
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.
