f0af389910 Enable comm_spawn of slave processes, currently only active for the rsh, slurm, and tm environments. Establish support for local rsh environments in the plm/base so that rsh of local slaves can be done by any environment that supports it. Create new orte_rsh_agent param so users can specify rsh agent from outside of rsh plm, and sym link that to the old plm_rsh_agent and pls_rsh_agent options.
Modify the orte-bootproxy to pass prefix for the remote slave to support hetero/hybrid scenarios

2966206f58 Fix a race condition in the IOF and add some new user-requested features:
1. fix a race condition whereby a proc's output could trigger an event prior to the other outputs being setup, thus c ausing the IOF to declare the proc "terminated" too early. This was really rare, but could happen.

2. add a new "timestamp-output" option that timestamp's each line of output

3. add a new "output-filename" option that redirects each proc's output to a separate rank-named file.

4. add a new "xterm" option that redirects the output of the specified ranks to a separate xterm window.

0704b98668 Add the ability to forward SIGTSTP (converted to SIGSTOP) and
SIGCONT to the a.outs.  By default, they are not forwarded and
the behavior remains as it has always been.  However, if one
runs with --mca orte_forward_job_control 1, then mpirun will
catch those two signals and forward them to the orteds which
will deliver them to the a.outs.  We have had requests for
this feature.

0435108834 Improve the efficiency of the launch system by changing the outer loop to being over app_context, and adding a flag to the app_context so the daemon can record that "this app is on my node" when decoding the launch msg.
If the --wdir option is given, check to see if the user provided a relative path. If so, convert it to an absolute path. This is needed to maintain consistent behavior across environements. Some environments automatically chdir to your current working directory when launching the remote orted, while others (e.g., ssh) don't. This levels the playing field and reduces user surprise.

007d68becc Make the data on local children and their jobs available globally on both daemons and the HNP. This simply shifts the data structures from the ODLS base to the orte globals area to support subsequent movement of the daemon collective operations from the odls to the grpcomm framework. As that will be a larger change, it will be implemented on a branch and rolled over separately.

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.

38eb301919 Follow-on to r19457. Rather than have #ifs in the middle of functions
(which neither Ralph nor I liked), don't allow the functions we don't
need to be visible.  Still not happy about the number of #ifs in the
code, but splitting the code further would have been a nightmare
and this was a good cutting point.

Also protected some variables that were declared but not instanced
so that users would be notified at compile time instead of link or
run time (in the case of dss constants) that things wouldn't work.

30f37f762d Enable co-location of debugger daemons during initial launch and when debugging a running job.
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.

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.

35a86b3347 Establish an MCA param "orte_allocation_required" so that a system can require the user have an RM-provided allocation in order to run. This helps prevent the problem where a user forgets to get an allocation on an RM-managed cluster, and then executes mpirun on the head node - thus causing all of their mpi procs to launch on the head node, usually bringing it to its knees.
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.

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.

a1d296ae03 This commit fixes ticket #1410
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

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.

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.

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.

828ae26d90 ORTE-level MCA params are defined in several places. Ompi_info cannot call orte_init due to an issue with the memory allocator, thus making it impossible for ompi_info to display all of the ORTE-level MCA params.
By consolidating them all into one function, ompi_info can call that function and register the desired variables. This also requires, however, that ompi_info call orte_output_init to avoid generating tons of error messages, so make that adjustment too. 

Fixes ticket #1314

In addition, orte_output has a race condition issue whereby calls to orte_output/verbose can occur prior to either the RML being defined/setup, or the HNP being defined. This latter occurs during the initialization of the orte_process_info structure. In both cases, there is no way orte_output can send the output to the HNP. Hence, the message must be simply output locally.

3e55fe6f6d Fold in the revised modex scheme. Move the ompi_proc_t modex portions to the RTE level since the daemons already have that info. Provide each process with the equivalent of a "nidmap" - both a map of what nodes are in the job, and a map of which node each process is on. This enables the use of static ports, though that hasn't been turned "on" in this commit.
Update the rsh tree spawn capability so we spawn the next wave of daemons before launching our own local procs.

629b95a2fe Afraid this has a couple of things mixed into the commit. Couldn't be helped - had missed one commit prior to running out the door on vacation.
Fix race conditions in abnormal terminations. We had done a first-cut at this in a prior commit. However, the window remained partially open due to the fact that the HNP has multiple paths leading to orte_finalize. Most of our frameworks don't care if they are finalized more than once, but one of them does, which meant we segfaulted if orte_finalize got called more than once. Besides, we really shouldn't be doing that anyway.

So we now introduce a set of atomic locks that prevent us from multiply calling abort, attempting to call orte_finalize, etc. My initial tests indicate this is working cleanly, but since it is a race condition issue, more testing will have to be done before we know for sure that this problem has been licked.

Also, some updates relevant to the tool comm library snuck in here. Since those also touched the orted code (as did the prior changes), I didn't want to attempt to separate them out - besides, they are coming in soon anyway. More on them later as that functionality approaches completion.

b110a247be Fix comm_spawn (maybe).
Comm_spawn was sticking during spawn_multiple because of a problem in the dpm - the modex there is asking processes to talk to each other in an allgather_list operation, but the procs don't have the required contact info to do so. The solution here was to ensure that all parent procs have full contact info for procs in the child job.

Admittedly, this isn't the long-term answer. We would like to have the contact info given to only the parent procs that were involved in the comm_spawn. There is a way to do that, but this will suffice to keep things working until that can be implemented and tested.

ff99aa054f In order to prevent orphaned processes when using non-unity routing methods, the procs need to realize that their local daemon is a critical connection - if that connection unexpectedly closes, they need to terminate.
This commit adds definition for a "lifeline" connection. For an HNP, there is no lifeline, so the lifeline proc is NULL. For a daemon, the lifeline is the HNP - the daemon should abort if it loses that connection.

For a proc using unity routed, the lifeline is the HNP since it connects directly to the HNP.

For a proc using tree routed, the lifeline is the local daemon.

Adjusted OOB to call abort if the lifeline (as opposed to HNP) connection is lost.

f9916811ae Make it so we do not mangle the options the user passes to their executeable. Fixes trac:1124
The change also:
 - cleans up and simplifies the command line processing code
 - adds an error output if more than one hostfile passed for a single app context
 - gets rid of the superfluous orte_app_context_map_t type, and instead use a simple argv of -host options
