6235a355de Correctly handle co-spawning of daemons when attaching to a running job. We cannot use the general process mappers as we only want debugger daemons spawned on nodes where application procs already exist. So custom build the map for the debugger daemon job, and have the plm just launch that job without doing its usual vm-spawn step.

2dd2694f25 Fix comm_spawn in oversubscribed conditions. IF oversubscription is allowed, let nodes flow into the mapper even if they are oversubscribed, constrained by the slots_max absolute ceiling. Cleanup error messages when comm_spawn fails so it correctly and succintly reports the ereror.

c56acf60ca Although we never really thought about it, we made an unconscious assumption in the mapper system - we assumed that the daemons would be placed on nodes in the order that the nodes appear in the allocation. In other words, we assumed that the launch environment would map processes in node order.
Turns out, this isn't necessarily true. The Cray, for example, launches processes in a toroidal pattern, thus causing the daemons to wind up somewhere other than what we thought. Other environments (e.g., slurm) are also capable of such behavior, depending upon the default mapping algorithm they are told to use.

Resolve this problem by making the daemon-to-node assignment in the affected environments when the daemon calls back and tells us what node it is on. Order the nodes in the mapping list so they are in daemon-vpid order as opposed to the order in which they show in the allocation. For environments that don't exhibit this mapping behavior (e.g., rsh), this won't have any impact.

Also, clean up the vm launch procedure a little bit so it more closely aligns with the state machine implementation that is coming, and remove some lingering "slave" code.

b475421c16 As promised, rationalize the rsh support. Remove rshbase and the base rsh support, centralizing all rsh support into the rsh component. Remove the "slave" launch support as that experiment is complete. Fix tree spawn and make that the default method for rsh launch, turning it "off" for qrsh as that system does not support tree spawn.

9b59d8de6f This is actually a much smaller commit than it appears at first glance - it just touches a lot of files. The --without-rte-support configuration option has never really been implemented completely. The option caused various objects not to be defined and conditionally compiled some base functions, but did nothing to prevent build of the component libraries. Unfortunately, since many of those components use objects covered by the option, it caused builds to break if those components were allowed to build.
Brian dealt with this in the past by creating platform files and using "no-build" to block the components. This was clunky, but acceptable when only one organization was using that option. However, that number has now expanded to at least two more locations.

Accordingly, make --without-rte-support actually work by adding appropriate configury to prevent components from building when they shouldn't. While doing so, remove two frameworks (db and rmcast) that are no longer used as ORCM comes to a close (besides, they belonged in ORCM now anyway). Do some minor cleanups along the way.

1ee7c39982 Fix some major bit-rot on scalable launch. If static ports are provided, then daemons can connect back to the HNP via the routed connection tree instead of doing so directly. In order to do that at scale, the node list must be passed as a regular expression - otherwise, the orted command line gets too long.
Over the course of time, usage of static ports got corrupted in several places, the "parent" info got incorrectly reset, etc. So correct all that and get the regex-based wireup going again.

Also, don't pass node lists if static ports aren't enabled - they are of no value to the orted and just create the possibility of overly-long cmd lines.

30fb002524 Take the first small step towards rationalizing rsh support. Create a new "rshbase" component that contains a simple rsh module - no tree spawn, uses all the base functions for launch support. Extend the base rsh support functions to include those functions in common across all rsh modules.
Only a minor change made to the current rsh module to avoid a naming conflict. Otherwise, left it alone to avoid creating conflicts with other external work. The current rsh module remains the default for rsh/ssh support, and continues to contain the support for SGE and Loadleveler.

40a2bfa238 WARNING: Work on the temp branch being merged here encountered problems with bugs in subversion. Considerable effort has gone into validating the branch. However, not all conditions can be checked, so users are cautioned that it may be advisable to not update from the trunk for a few days to allow MTT to identify platform-specific issues.
This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change.

Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation.

12cd07c9a9 Start reducing our dependency on the event library by removing at least one instance where we use it to redirect the program counter. Rolf reported occasional hangs of mpirun in very specific circumstances after all daemons were done. A review of MTT results indicates this may have been happening more generally in a small fraction of cases.
The problem was tracked to use of the grpcomm.onesided_barrier to control daemon/mpirun termination. This relied on messaging -and- required that the program counter jump from the errmgr back to grpcomm. On rare occasions, this jump did not occur, causing mpirun to hang.

This patch looks more invasive than it is - most of the affected files simply had one or two lines removed. The essence of the change is:

* pulled the job_complete and quit routines out of orterun and orted_main and put them in a common place

* modified the errmgr to directly call the new routines when termination is detected

* removed the grpcomm.onesided_barrier and its associated RML tag

* add a new "num_routes" API to the routed framework that reports back the number of dependent routes. When route_lost is called, the daemon's list of "children" is checked and adjusted if that route went to a "leaf" in the routing tree

* use connection termination between daemons to track rollup of the daemon tree. Daemons and HNP now terminate once num_routes returns zero

Also picked up in this commit is the addition of a new bool flag to the app_context struct, and increasing the job_control field from 8 to 16 bits. Both trivial.

099c3aad97 Fix a major foopah that broke debugger attach. With the revisions in updating proc state, we dropped the recording of each proc's pid. Thus, attaching debuggers would find a proctable whose pids all equal 0.
This required modification of the errmgr.update_state API so the pid could be passed in to the function that could update the proper data record(s). All calls to that API have been updated as well, but I obviously couldn't test them all.

Thanks to Dong Ahn (LLNL) for catching this problem!

Also fixed debugger daemon cospawn, both for initial launch and attach-while-running modes. Tested and verified on rsh and slurm.

afbe3e99c6 * Wrap all the direct error-code checks of the form (OMPI_ERR_* == ret) with
(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
 SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
 back the native error code.

* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
  (OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
  decode 'ret' to get the native error code.

88f5217a12 Cleanup the debugger daemon co-launch code and add an ability to test it. Implement ability to co-launch debugger daemons upon attach to a running job for jobs launched under rsh, slurm, and tm environments (others can easily be added if desired).
Add new mca params to test:

orte_debugger_test_daemon: Name of the executable to be used to simulate a debugger colaunch
orte_debugger_test_attach: Test debugger colaunch after debugger attachment

To test co-launch at job start, just set the orte_debugger_test_daemon param.

To test co-launch upon attach:
set orte_debugger_test_daemon
set orte_debugger_test_attach=1
set orte_enable_debug_cospawn_while_running=1
set orte_debugger_check_rate=<N> - defines the number of seconds to wait before "checking" for a debugger attaching

Added a "debugger" program to orte/test/mpi that just spins to simulate a debugger daemon.

efbb5c9b7c Revamp the errmgr framework to provide a greater range of optional behaviors, including different behaviors for daemons, and remove several looping messages across the code base:
* add hnp and orted modules to the errmgr framework. The HNP module contains much of the code that was in the errmgr base since that code could only be executed by the HNP anyway.

* update the odls to report process states directly into the active errmgr module, thus removing the need to send messages looped back into the odls cmd processor. Let the active errmgr module decide what to do at various states.

* remove the code to track application state progress from the plm_base_launch_support.c code. Update the plm modules to call the errmgr directly when a launch fails.

* update the plm_base_receive.c code to call the errmgr with state updates from remote daemons

* update the routed modules to reflect that process state is updated in the errmgr

* ensure that the orted's open the errmgr and select their appropriate module

* add new pretty-print utilities to print process and job state. Move the pretty-print of time info to a globally-accessible place

* define a global orte_comm function to send messages from orted's to the HNP so that others can overlay the standard RML methods, if desired.

* update the orterun help output to reflect that the "term w/o sync" error message can result from three, not two, scenarios

13d86e100b Courtesy of Ralph and Jeff:
Continue the reorganization of the configure system. Move files from the main config directory to their appropriate level-specific config directories. Modify the configure system to correctly handle compiler detection, test, and setup so that all things pertaining to opal and orte are done at the lower level, with the ompi configure system only looking at mpi-specific options.

Ensure the wrapper compilers for orte and ompi only get built when appropriate. Add support for c++ to the orte wrapper compilers, both script and non-script versions.

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.

c45ff0d59f Take the next step towards fully utilizing static ports for the daemons to eliminate the initial "phone home" to mpirun by modifying the orted termination procedure to eliminate the need for a full barrier-like operation. Instead, we add a "onesided" barrier to the grpcomm framework API that releases the orted once it has completed its own contribution to the barrier - i.e., the orteds now exit as the "ack" message rolls up towards mpirun instead of sending the "ack" directly to mpirun.
This causes the orteds in the routing tree to remain alive until all termination "acks" from orteds below them have passed through. Thus, if we use static ports, we no longer require a direct orted-to-mpirun connection.

Also modify the binomial routed module so it conforms to what all the other routed modules do and have all messages pass along the routing tree instead of short-circuiting between orteds. This further reduces the number of ports being opened on backend nodes.

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.

89559396ea Resolve a race condition when running under a SLURM environment.
The slurm plm fork/exec's a call to srun to launch its daemons. When mpirun terminates, it then sends out a "terminate" command to those daemons. The daemons respond back to mpirun, and then exit.

If slurm itself is running on a slow network, and mpirun is running the OOB across a fast network, then it is possible for mpirun to receive notification of daemon termination and exit -before- the srun can complete its bookkeeping and declare the job as complete. When this happens, slurm becomes confused and loses state.

Mucho bad. :-/

This commit changes the termination logic so that mpirun will wait for srun to report complete before exiting. It also enables fully routed communications since it no longer requires daemons to report back that they are terminating, thus allowing the daemons to terminate asynchronously (thereby breaking routing paths).

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...

4e0f34a062 When we hit an error prior to actually launching daemons, it would be nice if orterun didn't bark about daemons failing to launch, mpirun detecting a job failed, etc.
Add a new job state to indicate that we never attempted to launch. Flag such a scenario and avoid hitting all the other error messages.

be02211b4f Modify the wakeup system to make it more Windows-friendly. This allows Shiqing to consolidate the Windows-specific modifications into one location, and generalizes the wakeup procedure in case we hit other system-specific requirements.
This needs some soak time to ensure we haven't opened any race conditions. I tried to loop everything in the shutdown procedure through that trigger event call to ensure it all goes through the one-time locks as it did before so that someone hitting ctrl-c when we are already shutting down shouldn't cause problems. Just want to let people use it for awhile to verify.

a62b2a0150 Per the July technical meeting:
Standardize the handling of the orte launch agent option across PLMs. This has been a consistent complaint I have received - each PLM would register its own MCA param to get input on the launch agent for remote nodes (in fact, one or two didn't, but most did). This would then get handled in various and contradictory ways.

Some PLMs would accept only a one-word input. Others accepted multi-word args such as "valgrind orted", but then some would error by putting any prefix specified on the cmd line in front of the incorrect argument.

For example, while using the rsh launcher, if you specified "valgrind orted" as your launch agent and had "--prefix foo" on you cmd line, you would attempt to execute "ssh foo/valgrind orted" - which obviously wouldn't work.

This was all -very- confusing to users, who had to know which PLM was being used so they could even set the right mca param in the first place! And since we don't warn about non-recognized or non-used mca params, half of the time they would wind up not doing what they thought they were telling us to do.

To solve this problem, we did the following:

1. removed all mca params from the individual plms for the launch agent

2. added a new mca param "orte_launch_agent" for this purpose. To further simplify for users, this comes with a new cmd line option "--launch-agent" that can take a multi-word string argument. The value of the param defaults to "orted".

3. added a PLM base function that processes the orte_launch_agent value and adds the contents to a provided argv array. This can subsequently be harvested at-will to handle multi-word values

4. modified the PLMs to use this new function. All the PLMs except for the rsh PLM required very minor change - just called the function and moved on. The rsh PLM required much larger changes as - because of the rsh/ssh cmd line limitations - we had to correctly prepend any provided prefix to the correct argv entry.

5. added a new opal_argv_join_range function that allows the caller to "join" argv entries between two specified indices

Please let me know of any problems. I tried to make this as clean as possible, but cannot compile all PLMs to ensure all is correct.

0af7ac53f2 Fixes trac:1392, #1400
* add "register" function to mca_base_component_t
   * converted coll:basic and paffinity:linux and paffinity:solaris to
     use this function
   * we'll convert the rest over time (I'll file a ticket once all
     this is committed)
 * add 32 bytes of "reserved" space to the end of mca_base_component_t
   and mca_base_component_data_2_0_0_t to make future upgrades
   [slightly] easier
   * new mca_base_component_t size: 196 bytes
   * new mca_base_component_data_2_0_0_t size: 36 bytes
 * MCA base version bumped to v2.0
   * '''We now refuse to load components that are not MCA v2.0.x'''
 * all MCA frameworks versions bumped to v2.0
 * be a little more explicit about version numbers in the MCA base
   * add big comment in mca.h about versioning philosophy
