221fb9dbca ... Delayed due to notifier commits earlier this day ...
- Delete unnecessary header files using
   contrib/check_unnecessary_headers.sh after applying
   patches, that include headers, being "lost" due to
   inclusion in one of the now deleted headers...

   In total 817 files are touched.
   In ompi/mpi/c/ header files are moved up into the actual c-file,
   where necessary (these are the only additional #include),
   otherwise it is only deletions of #include (apart from the above
   additions required due to notifier...)

 - To get different MCAs (OpenIB, TM, ALPS), an earlier version was
   successfully compiled (yesterday) on:
   Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
   Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
   Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled

6c1cce8761 - For the upcoming header cleanup commit,
several header files (previously included by header-files)
   now have to be moved "upward".
   This is mainly system headers such as string.h, stdio.h and for
   networking, but also some orte headers.

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.

d81443cc5a - On the way to get the BTLs split out and lessen dependency on orte:
Often, orte/util/show_help.h is included, although no functionality
   is required -- instead, most often opal_output.h, or               
   orte/mca/rml/rml_types.h                                           
   Please see orte_show_help_replacement.sh commited next.

   in orte/tools/orte-top/orte-top.c

5e6d3ba289 Initial implementation of static ports. Provide an mca param to specify static port ranges to the OOB - can provide an
y combination of comma-separated values and ranges. Daemons will use the first port in the range, MPI procs will use the other ports in the range assuming that they know their node rank in time and enough ports were specified.

NOTE: this capability only works under specific conditions. I will outline more about this in a note to devel as the remainder of the implementation progresses. For now, the only environment where this works is slurm. The linear routed module has also been adjusted to work with static ports so that all messaging flows strictly through the topology, including the initial daemon callback - thus limiting the number of sockets opened by mpirun.

728a24c8ec After considerable patience and help with debugging/testing from Tim M and Jeff S, return a completed and pretty well tested patch of the IOF to the trunk. This commit includes the previously reverted r20074, r20068, and r20064, as well as changes to fix those commits.
Basically, the remaining problem turned out to be:

1. closing stdout/stderr during orte_finalize of mpirun

2. inadvertently setting up a write event on fd = -1

3. devising a scheme to more accurately track when the stdin write event was active vs closed so it only got released once

This passed prelim MTT testing by Jeff and Tim, but should soak for awhile before migrating to 1.3.

This commit was SVN r20106.

a07660aea8 Bring over the IOF completion changes. This commit fixes the long-occurring problem whereby application procs could, under some circumstances, lose their final prints to stdout/err. The commit includes:
1. coordination of job completion notification to include a requirement for both waitpid detection AND notification that all iof pipes have been closed by the app

2. change of all IOF read and write events to be non-persistent so they can properly be shutdown and restarted only when required

3. addition of a delay (currently set to 10ms) before restarting the stdin read event. This was required to ensure that the stdout, stderr, and stddiag read events had an opportunity to be serviced in scenarios where large files are attached to stdin.

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...

6e5d844c36 Roll in the revamped IOF subsystem. Per the devel mailing list email, this is a complete rewrite of the iof framework designed to simplify the code for maintainability, and to support features we had planned to do, but were too difficult to implement in the old code. Specifically, the new code:
1. completely and cleanly separates responsibilities between the HNP, orted, and tool components.

2. removes all wireup messaging during launch and shutdown.

3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol.

4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0.

5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none".

6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout.

7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output"

This is not intended for the 1.3 release as it is a major change requiring considerable soak time.

48c3de1865 Fix a problem in the plm "failed to start" code observed by Jeff. When we are unable to launch to a specific node because it doesn't exist or is down, the system would hang and/or segv. The reason for the hang was that we were "firing" the orted exit trigger prior to its timer event being defined - thus "locking" that one-shot and preventing it from firing when we actually were ready to use it.
The segv was caused by the fact that we don't really know which daemon failed to start (at least, in most cases), so we didn't set a pointer to the aborted proc object. All we really wanted, though, was to ensure that mpirun returned a non-zero exit status, so the fix was to simply return the default error status.

Provide support for four MPIR extensions that allow specification of debugger daemon executable, argv for the debugger daemon, whether or not to forward debugger daemon IO, and whether or not debugger daemon will piggy-back on ORTE OOB network. Last is not yet implemented.

No change in behavior or operation occurs unless (a) the debugger specifically utilizes the extensions and, for co-locate while running, the user specifically enables the capability via an MCA param. Two of the MPIR extensions supported here are used in a widely-used debugger for a large-scale installation. The other two extensions are new and being utilized in prototype work by several debuggers for possible future release.

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.

Unfortunately, our PLM modules were using the local environ instead of the saved copy, thus missing a number of things that really should have been included. From what I see, we got away with the error because the PLM's were duplicating all that setup logic themselves - I'll clean this up over the next few days.

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.

7bee71aa59 Fix a potential, albeit perhaps esoteric, race condition that can occur for fast HNP's, slow orteds, and fast apps. Under those conditions, it is possible for the orted to be caught in its original send of contact info back to the HNP, and thus for the progress stack never to recover back to a high level. In those circumstances, the orted can "hang" when trying to exit.
Add a new function to opal_progress that tells us our recursion depth to support that solution.

Yes, I know this sounds picky, but good ol' Jeff managed to make it happen by driving his cluster near to death...

Also ensure that we declare "failed" for the daemon job when daemons fail instead of the application job. This is important so that orte knows that it cannot use xcast to tell daemons to "exit", nor should it expect all daemons to respond. Otherwise, it is possible to hang.

After lots of testing, decide to default (again) to slurm detecting failed orteds. This proved necessary to avoid rather annoying hangs that were difficult to recover from. There are conditions where slurm will fail to launch all daemons (slurm folks are working on it), and yet again, good ol' Jeff managed to find both of them.

Thanks you Jeff! :-/

b456fb2d42 Upgrade the node/orted failure detection code to cover all environments. Use the native environment's capabilities where possible - e.g., SLURM detects orted failure and can report it. Elsewhere, use a heartbeat system to detect orted failure - e.g., for TM and rsh. Heart rate is set via mca param. The HNP checks for callback every 2*heartrate, declares orted failure if not seen in last 2*heartrate time.
Also detect orted failed-to-start by setting timeout on launch. Currently only used in TM launcher.

Neither detection is enabled by default, but are only active if heartrate is set and/or launch timeout is set. Exception for SLURM as orted failure is always detected and reported.

More info to come on devel list.

72530f8fed Cleanly handle the failed start of an orted, or its unexpected failure after start. This commit will allow mpirun to exit cleanly when this occurs, and does a best-effort attempt to cleanup the mess. However, it still has two unresolved issues that need to be eventually addressed:
1. it depends upon the ability of the native environment to alert us that the orted has died/failed to start. I have included that support for SLURM, but other environments need to be done.

2. for some yet-to-be-determined reason, the message that tells the remaining daemons to "die" isn't getting out of the RML, even though no obvious blockage is standing in the way. Work will continue on resolving that problem. For now, the orteds appear to be exiting on their own quite nicely when they see their HNP "lifeline" disappear.

This represents the best-available fix for ticket #221 so I am closing that ticket at this time.

e7ecd56bd2 This commit represents a bunch of work on a Mercurial side branch. As
such, the commit message back to the master SVN repository is fairly
long.

= ORTE Job-Level Output Messages =

Add two new interfaces that should be used for all new code throughout
the ORTE and OMPI layers (we already make the search-and-replace on
the existing ORTE / OMPI layers):

 * orte_output(): (and corresponding friends ORTE_OUTPUT,
   orte_output_verbose, etc.)  This function sends the output directly
   to the HNP for processing as part of a job-specific output
   channel.  It supports all the same outputs as opal_output()
   (syslog, file, stdout, stderr), but for stdout/stderr, the output
   is sent to the HNP for processing and output.  More on this below.
 * orte_show_help(): This function is a drop-in-replacement for
   opal_show_help(), with two differences in functionality:
   1. the rendered text help message output is sent to the HNP for
      display (rather than outputting directly into the process' stderr
      stream)
   1. the HNP detects duplicate help messages and does not display them
      (so that you don't see the same error message N times, once from
      each of your N MPI processes); instead, it counts "new" instances
      of the help message and displays a message every ~5 seconds when
      there are new ones ("I got X new copies of the help message...")

opal_show_help and opal_output still exist, but they only output in
the current process.  The intent for the new orte_* functions is that
they can apply job-level intelligence to the output.  As such, we
recommend that all new ORTE and OMPI code use the new orte_*
functions, not thei opal_* functions.

=== New code ===

For ORTE and OMPI programmers, here's what you need to do differently
in new code:

 * Do not include opal/util/show_help.h or opal/util/output.h.
   Instead, include orte/util/output.h (this one header file has
   declarations for both the orte_output() series of functions and
   orte_show_help()).
 * Effectively s/opal_output/orte_output/gi throughout your code.
   Note that orte_output_open() takes a slightly different argument
   list (as a way to pass data to the filtering stream -- see below),
   so you if explicitly call opal_output_open(), you'll need to
   slightly adapt to the new signature of orte_output_open().
 * Literally s/opal_show_help/orte_show_help/.  The function signature
   is identical.

=== Notes ===

 * orte_output'ing to stream 0 will do similar to what
   opal_output'ing did, so leaving a hard-coded "0" as the first
   argument is safe.
 * For systems that do not use ORTE's RML or the HNP, the effect of
   orte_output_* and orte_show_help will be identical to their opal
   counterparts (the additional information passed to
   orte_output_open() will be lost!).  Indeed, the orte_* functions
   simply become trivial wrappers to their opal_* counterparts.  Note
   that we have not tested this; the code is simple but it is quite
   possible that we mucked something up.

= Filter Framework =

Messages sent view the new orte_* functions described above and
messages output via the IOF on the HNP will now optionally be passed
through a new "filter" framework before being output to
stdout/stderr.  The "filter" OPAL MCA framework is intended to allow
preprocessing to messages before they are sent to their final
destinations.  The first component that was written in the filter
framework was to create an XML stream, segregating all the messages
into different XML tags, etc.  This will allow 3rd party tools to read
the stdout/stderr from the HNP and be able to know exactly what each
text message is (e.g., a help message, another OMPI infrastructure
message, stdout from the user process, stderr from the user process,
etc.).

Filtering is not active by default.  Filter components must be
specifically requested, such as:

{{{
$ mpirun --mca filter xml ...
}}}

There can only be one filter component active.

= New MCA Parameters =

The new functionality described above introduces two new MCA
parameters:

 * '''orte_base_help_aggregate''': Defaults to 1 (true), meaning that
   help messages will be aggregated, as described above.  If set to 0,
   all help messages will be displayed, even if they are duplicates
   (i.e., the original behavior).
 * '''orte_base_show_output_recursions''': An MCA parameter to help
   debug one of the known issues, described below.  It is likely that
   this MCA parameter will disappear before v1.3 final.

= Known Issues =

 * The XML filter component is not complete.  The current output from
   this component is preliminary and not real XML.  A bit more work
   needs to be done to configure.m4 search for an appropriate XML
   library/link it in/use it at run time.
 * There are possible recursion loops in the orte_output() and
   orte_show_help() functions -- e.g., if RML send calls orte_output()
   or orte_show_help().  We have some ideas how to fix these, but
   figured that it was ok to commit before feature freeze with known
   issues.  The code currently contains sub-optimal workarounds so
   that this will not be a problem, but it would be good to actually
   solve the problem rather than have hackish workarounds before v1.3 final.

d97a4f880d Shift the daemon collective operation to the ODLS framework. Ensure we track the collectives per job to avoid race conditions. Take advantage of the new capabilities of the routed framework to define aggregating trees for the daemon collective, and to track which daemons are participating to handle the case of sparse participation.
Make it all work with comm_spawn in the case of all procs on previously occupied nodes, some new procs on new nodes, and mixtures of the two.

Note: comm_spawn now works with both binomial and linear routed modules. There remains a problem of spawned procs not properly getting updated contact info for the parent proc when run in the direct routed mode...but that's for another day.
