0b9552cd4e Expand the ESS framework's API to include a new function "query_sys_info" that allows the caller to retrieve key-value pairs of info on the local system capabilities (e.g., cpu type/model). Have each daemon and the HNP "sense" that information and provide it to their local procs to avoid having every proc querying the system directly.

dc9370598f This looks more like the correct solution. We only pack the known information, so
we can now deal with partial mapping without segfaulting.

d66632fdc9 Reorder the nidmap encoding function. Add a check to make sure we don't write
outside the boundaries of the allocated array.

However, the problem is still there. If we have rmaps file containing only
partial information the num_procs get set to the wrong value (the number of
hosts in the rmaps file instead of the number of processes requested on the
command line).

60edbc7220 Fix hetero operations and comm_spawn (to a point).
Remove all architecture references from ORTE and put them back in the modex using modex_send/recv calls.

Hetero operations are now fully supported again. Comm_spawn now works up to the point where it segfaults due to an error in the CID code - which now allows Edgar to dig further! :-)

f139cfd28a Fully enable the use of static ports to minimize connections on mpirun. When static ports are provided, daemons will automatically use routes defined by the selected routed module to callback to mpirun during startup, thus elimating the dedicated daemon-to-mpirun connection. Therefore, the total number of connections on mpirun will equal the fanout of the routed module (instead of #nodes in job).
Add a new tm ess module that exploits this capability.

Update the various plm modules to enable it - just a minor change reflecting an added param to a plm base function.

Additional fixes included:

1. remove an erroneous cleanup of session directories in the tool finalize procedure - tools don't create session directories to begin with!

2. fix a duplicate free when attempting to execute a non-existent app

3. cleanup an typo in the comm utilities 

4. fix comm_spawn - was perturbed by the changes in pack/unpack of orte_job_t to properly support orte-ps

Been tested on slurm and tm machines, using all tests in orte/test/mpi. May run into issue with command line length on large jobs due to inclusion of node info to support static ports - will fix this next with addition of regexp generator to compress that info.

4be24521aa Modify the orte_process_info structure to handle a broader range of process types by replacing the individual booleans with a 32-bit bitmap. Use a set of #define's to define the individual bits, and a set of matching macros to test for them. Update the orte code base to use the macros instead of the booleans.
Minor mod to the ompi layer to use the new #define's - just one-line name replacements.

f11931306a Modify the accounting system to recycle jobids. Properly recover resources from nodes and jobs upon completion. Adjustments in several places were required to deal with sparsely populated job, node, and proc arrays as a result of this change.
Correct an error wrt how jobids were being computed. Needed to ensure that the job family field was not overrun as we increment jobids for comm_spawn.

Update the slurm plm module so it uses the new slurm termination procedure (brings trunk back into alignment with 1.3 branch).

Update the slurmd ess component so it doesn't get selected if we are running a singleton inside of a slurm allocation.

Cleanup HNP init by moving some code that had been in orte_globals.c for historical reasons into the ess hnp module, and removing the call to that code from the ess_base_std_prolog


NOTE: this change allows orte to support an infinite aggregate number of comm_spawn's, with up to 64k being alive at any one instant. HOWEVER, the MPI layer currently does -not- support re-use of jobids. I did some prototype coding to revise the ompi_proc_t structures, but the BTLs are caching their own data, and there was no readily apparent way to update it. Thus, attempts to spawn more than the 64k limit will abort to avoid causing the MPI layer to hang.

   actually showed two *missing* #include "orte/util/show_help.h"     
   in orte/mca/odls/base/odls_base_default_fns.c and                  
   in orte/tools/orte-top/orte-top.c

d4dfb1b7a7 Plug a few bugs in the decoding of pidmaps:
1. after we get enough jobs in the pidmap, the address of the jobmap pointer array data can move due to realloc. Need to reset the jobs pointer each time through to ensure it is pointing to valid data

2. when we exit the loop, rc will be set to an error due to reading past end of buffer - need to reset so it is ignored

3. need to ensure we only try to read one jobid each time through loop

9a57db4a81 To support comm_spawn in fully routed environments, daemons need to know the route to all procs in their job family. They already had this information, but were not retaining it. The infrastructure to do so has existed for some time - just never had the time to complete it.
This commit does that by ensuring that daemons retain knowledge of proc location for all procs in their job family. It required a minor change to the ESS API to allow the daemons to update their pidmaps as data was received. In addition, the routed modules have been updated to take advantage of the newly available info, and the encode/decode pidmap utilities have been updated to communicate the required info in the launch message.

f54fda489e This is a first step towards supporting fully-routed OOB communications:
1. remove direct routed module (hooray!)

2. add radix tree routed module (binomial remains default)

3. remove duplicate data storage - orteds were storing nidmap and pidmap data in odls, everyone else in ess

4. add ess APIs to update nidmap, add new pidmap - used only by orteds for MPI-2 support

5. modify code to eliminate multiple calls to orte_routed.update_route that recreated info already in ess pidmap. Add ess API to lookup that info instead. Modify routed modules to utilize that capability

6. setup new ability to shutdown orteds without sending back an "ack" message to mpirun - not utilized yet, will require some changes to plm terminate_orteds functions in managed environments (coming soon)

Initial tests indicating that fully routing comm via defined routing trees may not actually have a significant cost for operations like IB QP setup. More tests required to confirm.

This will require an autogen...

ba5498cdc6 Repair the MPI-2 dynamic operations. This includes:
1. repair of the linear and direct routed modules

2. repair of the ompi/pubsub/orte module to correctly init routes to the ompi-server, and correctly handle failure to correctly parse the provided ompi-server URI

3. modification of orterun to accept both "file" and "FILE" for designating where the ompi-server URI is to be found - purely a convenience feature

4. resolution of a message ordering problem during the connect/accept handshake that allowed the "send-first" proc to attempt to send to the "recv-first" proc before the HNP had actually updated its routes.

Let this be a further reminder to all - message ordering is NOT guaranteed in the OOB

5. Repair the ompi/dpm/orte module to correctly init routes during connect/accept.

Reminder to all: messages sent to procs in another job family (i.e., started by a different mpirun) are ALWAYS routed through the respective HNPs. As per the comments in orte/routed, this is REQUIRED to maintain connect/accept (where only the root proc on each side is capable of init'ing the routes), allow communication between mpirun's using different routing modules, and to minimize connections on tools such as ompi-server. It is all taken care of "under the covers" by the OOB to ensure that a route back to the sender is maintained, even when the different mpirun's are using different routed modules.

6. corrections in the orte/odls to ensure proper identification of daemons participating in a dynamic launch

7. corrections in build/nidmap to support update of an existing nidmap during dynamic launch

8. corrected implementation of the update_arch function in the ESS, along with consolidation of a number of ESS operations into base functions for easier maintenance. The ability to support info from multiple jobs was added, although we don't currently do so - this will come later to support further fault recovery strategies

9. minor updates to several functions to remove unnecessary and/or no longer used variables and envar's, add some debugging output, etc.

10. addition of a new macro ORTE_PROC_IS_DAEMON that resolves to true if the provided proc is a daemon

There is still more cleanup to be done for efficiency, but this at least works.

Tested on single-node Mac, multi-node SLURM via odin. Tests included connect/accept, publish/lookup/unpublish, comm_spawn, comm_spawn_multiple, and singleton comm_spawn.

9613b3176c Effectively revert the orte_output system and return to direct use of opal_output at all levels. Retain the orte_show_help subsystem to allow aggregation of show_help messages at the HNP.
After much work by Jeff and myself, and quite a lot of discussion, it has become clear that we simply cannot resolve the infinite loops caused by RML-involved subsystems calling orte_output. The original rationale for the change to orte_output has also been reduced by shifting the output of XML-formatted vs human readable messages to an alternative approach.

I have globally replaced the orte_output/ORTE_OUTPUT calls in the code base, as well as the corresponding .h file name. I have test compiled and run this on the various environments within my reach, so hopefully this will prove minimally disruptive.
