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.
This commit was SVN r20022.
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).
This commit was SVN r20018.
1. modify the iof to track when a proc actually closes all of its open iof output pipes. When this occurs, notify the odls that the proc's iof is complete. This is done via a zero-time event so that we can step out of the read event before processing the notification.
2. in the odls, modify the waitpid callback so it only flags that it was called. Add a function to receive the iof-complete notification, and a function that checks for both iof complete and waitpid callback before declaring a proc fully terminated. This ensures that we read and deliver -all- of the IO prior to declaring the job complete.
Also modified the odls call to orte_iof.close (and the component's implementation) so it only closes stdin, leaving the other io channels alone. This fixes the other half of the known problem.
This should fix the ticket on this subject, but I'll wait to close it pending further testing in the trunk.

The following SVN revision numbers were found above:
r19866 --> open-mpi/ompi@f54fda489e
1. register "mpi_preconnect_all" as a deprecated synonym for "mpi_preconnect_mpi"
2. remove "mpi_preconnect_oob" and "mpi_preconnect_oob_simultaneous" as these are no longer valid.
3. remove the routed framework's "warmup_routes" API. With the removal of the direct routed component, this function at best only wasted communications. The daemon routes are completely "warmed up" during launch, so having MPI procs order the sending of additional messages is simply wasteful.
4. remove the call to orte_routed.warmup_routes from MPI_Init. This was the only place it was used anyway.
The FAQs will be updated to reflect this changed situation, and a CMR filed to move this to the 1.3 branch.

This commit was SVN r19869.
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...

2. add a test program and data to stress iof for stdin
3. cleanup a debug statement that caused memory corruption when reading large files
4. some minor cleanups to correctly handle xon/xoff scenarios
This commit was SVN r19792.
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.

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.

If a message cannot be routed because the addressee isn't yet known, then the message is held on a queue in the RML for a period of time (currently set to 500 millisec). At the end of that time, we pop the message from the list and attempt to send it again. This action requires that we convert the header back to
network-byte-order before calling the OOB.
If the message still cannot be routed, we put the message back on the list and reset the timer. However, since we are going to convert the header when it com
es off of the list, we have to ntoh it before putting it back on the list so it all comes out right. This step was missing.
Thus, the problem only showed up relatively rarely because a message would have to be pushed onto the queue at least twice for the problem to surface.
This should fix a specific ticket (1389), but we will wait to see the results of MTT runs to verify. Note that we really don't know why a message is rattling around in the RML for so long, especially since this all seems to be happening during finalize, so this could cause mpirun to hang. Or it could simply trash the message and exit cleanly. Shall be interesting to see!

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.

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.
This commit was SVN r19159.
During the discussion of MPI-2 functionality, it was pointed out by Aurelien that there was an inherent race condition between startup of ompi-server and mpirun. Specifically, if someone started ompi-server to run in the background as part of a script, and then immediately executed mpirun, it was possible that an MPI proc could attempt to contact the server (or that mpirun could try to read the server's contact file before the server is running and ready.
At that time, we discussed createing a new tool "ompi-wait-server" that would wait for the server to be running, and/or probe to see if it is running and return true/false. However, rather than create yet another tool, it seemed just as effective to add the functionality to mpirun.
Thus, this commit creates two new mpirun cmd line flags (hey, you can never have too many!):
--wait-for-server : instructs mpirun to ping the server to see if it responds. This causes mpirun to execute an rml.ping to the server's URI with an appropriate timeout interval - if the ping isn't successful, mpirun attempts it again.
--server-wait-time xx : sets the ping timeout interval to xx seconds. Note that mpirun will attempt to ping the server twice with this timeout, so we actually wait for twice this time. Default is 10 seconds, which should be plenty of time.
This has only lightly been tested. It works if the server is present, and outputs a nice error message if it cannot be contacted. I have not tested the race condition case.
This commit was SVN r19152.
Since OMPI allows mpirun to default to the local node, and since users want to retain the option to co-locate procs with mpirun, we needed another param to block this error case.

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.

Mpirun - and the orteds - were doing their best to whack all session dirs on their nodes just in case there was something lingering due to an abnormal termination. Unfortunately, they were -too- good at it. They were whacking all session directories under the user's name, even those from other mpiruns!
This adds another layer to the session dir tree so that we can denote which jobs come from our own job family, and restricts the cleanup operation to only session dirs from within our own job family. So we'll still cleanup anything due to our own mpirun, but won't whack any other mpirun from this user.
Call it being polite...

Cleanup the logic in the odls for when processes terminate. It turns out that we were only going through the kill_proc logic once instead of looping over all local children when we ordered a daemon to kill its local procs. This went unnoticed for some time as for most systems the local procs were terminated anyway when the daemon terminated due to the parent/child relationship.
Solaris is apparently different - the children are not automatically terminated when the parent dies. As a result, it acts as a detector for this bug.

Fix a few bugs in the mappers:
1. Ensure that bynode with no -np fills all available slots - it just does so with the ranks set bynode instead of byslot
2. fix --nolocal behavior so it works correctly in all cases. We still have to test the host's name using opal_ifislocal in the mapper because the name returned by gethostname to orte_process_info.hostname can be an FQDN, but a hostfile may contain a non-FQDN version.
3. Add missing --nolocal logic to the seq mapper
Oversubscribed mapping seemed to be working okay without repair, so I couldn't verify my own bug report in that regard.
Also included are some preliminary changes to support the modified hostfile behavior, which will be committed shortly:
1. removed the totally useless "allocate" field in the orte_node_t object since every node is automatically allocated for use - and everything ignored the field anyway
2. correctly initialize the slots_alloc field when the allocation is read

Details:
* remove opal_paffinity_alone MCA param; restore mpi_paffinity_alone

* move opal_paffinity_slot_list param registration to paffinity base
* ompi_mpi_init() calls opal_paffinity_base_slot_list_set(); if that
succeeds use that. If no slot list was set, see if
mpi_paffinity_alone was set. If so, bind this process to its Node
Local Rank (NLR). The NLR is the ORTE-maintained slot ID; if you
COMM_SPAWN to a host in this ORTE universe that already has procs
on it, the NLR for the new job will start at N (not 0). So this is
slightly better than mpi_paffinity_alone in the v1.2 series.
* If a slot list is specified *and* mpi_paffinity_alone is set, we
display an error and abort.
* Remove calls from rmaps/rank_file component to register and lookup
opal_paffinity mca params.
* Remove code in orte/odls that set affinities - instead, have them
just pass a slot_list if it exists.

Actually, the problem was that we were simply -adding- any enviro MCA params to whatever had been found on the cmd line.

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.

Ensure that routes to remote procs are set on the HNP before completing launch so that the debugger message can be sent. Solves a race condition that can exist in those environments where the HNP does not have local procs.

Update the ESS API so we can update the stored arch's should the modex include that info. Update ompi/proc to check/set the arch for remote procs, and add that function call to mpi_init right after the modex is done.
Setup to allow other grpcomm modules to decide whether or not to add the arch to the modex, and to detect if other entries have been made. If not, then the modex can just fall through. Begin setting up some logic in the "basic" module to handle different arch situations.
For now, default to the "bad" module so we will work in all situations, even though we may be sending around more info than we really require.
This fixes ticket #1340

Some minor changes to help facilitate debugger support so that both mpirun and yod can operate with it. Still to be completed.

is still to use the C based wrapper compilers (which have many more features
and are more well tested). The Perl compilers are enabled with the option
--enable-script-wrapper-compilers, which also ignores the option
--disable-binaries (ie --enable-script-wrapper-compilers --disable-binaries
will result in perl-based wrapper compilers being installed, but no other
binaries being installed).

This allows r18645 to fix the memory corruption issue, but also allows us to resolve the memory leaks cited by CID 1039

This commit repairs the debugger initialization procedure. I am not closing the ticket, however, pending Jeff's review of how it interfaces to the ompi_debugger code he implemented. There were duplicate symbols being created in that code, but not used anywhere. I replaced them with the ORTE-created symbols instead. However, since they aren't used anywhere, I have no way of checking to ensure I didn't break something.
So the ticket can be checked by Jeff when he returns from vacation... :-)

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.

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! :-/
