sandbox team has informed me that they are getting rid of SANDBOX_PID
in the future and that using SANDBOX_ON would be preferred.

To resolve this situation, add the ability to specify a backend topology file that mpirun shall use for its mapping operations. Create a new "set_topology" function in opal hwloc to support it.

performance should be sufficient for most cases. If not we can always change
the function again.

some relevant updates/new functionality in the opal/mca/hwloc and
orte/mca/rmaps bases. This work was mainly developed by Mellanox,
with a bunch of advice from Ralph Castain, and some minor advice from
Brice Goglin and Jeff Squyres.
Even though this is mainly Mellanox's work, Jeff is committing only
for logistical reasons (he holds the hg+svn combo tree, and can
therefore commit it directly back to SVN).
-----
Implemented distance-based mapping algorithm as a new "mindist"
component in the rmaps framework. It allows mapping processes by NUMA
due to PCI locality information as reported by the BIOS - from the
closest to device to furthest.
To use this algorithm, specify:
{{{mpirun --map-by dist:<device_name>}}}
where <device_name> can be mlx5_0, ib0, etc.
There are two modes provided:
1. bynode: load-balancing across nodes
1. byslot: go through slots sequentially (i.e., the first nodes are
more loaded)
These options are regulated by the optional ''span'' modifier; the
command line parameter looks like:
{{{mpirun --map-by dist:<device_name>,span}}}
So, for example, if there are 2 nodes, each with 8 cores, and we'd
like to run 10 processes, the mindist algorithm will place 8 processes
to the first node and 2 to the second by default. But if you want to
place 5 processes to each node, you can add a span modifier in your
command line to do that.
If there are two NUMA nodes on the node, each with 4 cores, and we run
6 processes, the mindist algorithm will try to find the NUMA closest
to the specified device, and if successful, it will place 4 processes
on that NUMA but leaving the remaining two to the next NUMA node.
You can also specify the number of cpus per MPI process. This option
is handled so that we map as many processes to the closest NUMA as we
can (number of available processors at the NUMA divided by number of
cpus per rank) and then go on with the next closest NUMA.
The default binding option for this mapping is bind-to-numa. It works
if you don't specify any binding policy. But if you specified binding
level that was "lower" than NUMA (i.e hwthread, core, socket) it would
bind to whatever level you specify.

The following SVN revisions from the original message are invalid or
inconsistent and therefore were not cross-referenced:

http://www.open-mpi.org/community/lists/users/2013/04/21689.php, the
assert in opal_datatype_is_contiguous_memory_layout() is not always
correct -- he supplied a test case where it was not valid,
essentially:
1. Call MPI_Type_create_indexed_block(0, ..., &newtype) and commit newtype
1. Call MPI_Type_create_resized(newtype, 0, nonzero_value, &resized) and commit resized
1. Call MPI_File_set_view with resized
This will eventually call opal_datatype_is_contiguous_memory_layout(),
and the assert will fail. After some consultation with George, it was
determined that the assert() is basically good, but it needs to also
check for (count != 0).

This is not in response to any known bug, but rather just a
pre-emptive, defensive move to help prevent bugs in code that forgets
to initialize a field.

representation is not correctly optimized (it is off by the extend).
During the data representation process, if the opportunity to merge several
items appear, we replace them with the new merged element. However, if one
of the components of this merged element was comming from a "loop representation"
then the new first element of this loop must have a displacement moved by the
extent of the loop.

Provide some nice error messages if we fail to set the limits. Since the user had to specifically request we set the limit, treat failure as an error-out situation.

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.
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.
