This change does a couple of things:
1. Since the USE_PARENT_ALLOC attribute is a directive about regarding allocation of resources to a job, it more properly should be an attribute of the RAS. Change the name to reflect that and move the attribute define to the ras_types.h file.
2. Add the attributes list to the RMAPS map_job interface. This provides us with the desired flexibility to dynamically specify directives for mapping. The system will - in the absence of any attribute-based directive - default to the values provided in the MCA parameters (either from environment or command-line interface).

I have tested on rsh, slurm, bproc, and tm. Bproc continues to have a problem (will be asking for help there).
Gridengine compiles but I cannot test (believe it likely will run).
Poe and xgrid compile to the extent they can without the proper include files.

Update the help text to report errors when not following that rule.
Also updated the RMAPS help text to reflect the reorganization of some of the round-robin code into the base.
The new functionality has been tested under Mac OS-X and on Odin using an MPI program. Both byslot and bynode mapping have been checked and verified. Operational support for other systems needs to be verified - I respectfully request people's help in doing so.

1. Modifies the RAS framework so it correctly stores and retrieves the actual slots in use, not just those that were allocated. Although the RAS node structure had storage for the number of slots in use, it turned out that the base function for storing and retrieving that information ignored what was in the field and simply set it equal to the number of slots allocated. This has now been fixed.
2. Modified the RMAPS framework so it updates the registry with the actual number of slots used by the mapping. Note that daemons are still NOT counted in this process as daemons are NOT mapped at this time. This will be fixed in 2.0, but will not be addressed in 1.x.
3. Added a new MCA parameter "rmaps_base_no_oversubscribe" that tells the system not to oversubscribe nodes even if the underlying environment permits it. The default is to oversubscribe if needed and the underlying environment permits it. I'm sure someone may argue "why would a user do that?", but it turns out that (looking ahead to dynamic resource reservations) sometimes users won't know how many nodes or slots they've been given in advance - this just allows them to say "hey, I'd rather not run if I didn't get enough".
4. Reorganizes the RMAPS framework to more easily support multiple components. A lot of the logic in the round_robin mapper was very valuable to any component - this has been moved to the base so others can take advantage of it.
5. Added a new test program "hello_nodename" - just does "hello_world" but also prints out the name of the node it is on.
6. Made the orte_ras_node_t object a full ORTE data type so it can more easily be copied, packed, etc. This proved helpful for the RMAPS code reorganization and might be of use elsewhere too.

/tmp/tm-merge). Validated by RHC. Summary:
- Add --nolocal (and -nolocal) options to orterun
- Make some scalability improvements to the tm pls
This commit was SVN r10651.
- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

The logs from this branch are much more descriptive than I will put
here (including a *really* long description from last night). Here's
the short version:
- fixed some broken implementations in ras and rmaps
- "orterun --host ..." now works and has clearly defined semantics
(this was the impetus for the branch and all these fixes -- LANL had
a requirement for --host to work for 1.0)
- there is still a little bit of cleanup left to do post-1.0 (we got
correct functionality for 1.0 -- we did not fix bad implementations
that still "work")
- rds/hostfile and ras/hostfile handshaking
- singleton node segment assignments in stage1
- remove the default hostfile (no need for it anymore with the
localhost ras component)
- clean up pls components to avoid duplicate ras mapping queries
- [possible] -bynode/-byslot being specific to a single app context
This commit was SVN r7664.
- change the framework opens to [mostly] use the new MCA param API
- properly pass in framework debug output streams to the
mca_base_component_open() function
