9166a8cc95 Per telecon today, add a flag so we only warn once about reentrant libevent loops - this will allow developers to better diagnose the problem as we won't swamp filesystems with warning messages.

446e33a5d8 There are cases where we want to use the novm state machine, but the backend node topology differs from that where mpirun is executing. In those cases, we can wind up thinking we are oversubscribed because the head node has fewer cores than the compute nodes.
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.

0b5c1f2ea8 Add 'generic' support for PMI2 (previously, we checked for PMI2 only on Cray systems.) If your resource manager (e.g. SLURM) has support for PMI2, then the --with-pmi configure flag will enable its usage. If you don't have PMI2, then you will fallback to regular old PMI1.

6d173af329 This commit introduces a new "mindist" ORTE RMAPS mapper, as well as
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.

45af6cf59e The move of the orte_db framework to opal required that we create an opaque opal_identifier_t type as OPAL cannot know anything about the ORTE process name. However, passing a value down to opal and then having the db components reference it causes alignment issues on Solaris Sparc platforms. So pass the pointer instead and do the old "memcpy" trick to avoid the problem.

020b9991a4 Introduce the MCA framework system. This formalizes the interface frameworks must provide.
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.

cf377db823 MCA/base: Add new MCA variable system
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.
