4bd25f587c Begin handling the case of lost connections by having the OOB report it to the errmgr instead of the routed framework. Add an "app" component to t
he errmgr framework so that it can decide how to respond - which for now at least is just to check for lifeline and abort if so.

Add a new error constant to indicate that the error is "unrecoverable" so the oob can know it needs to abort.

d4f56cff61 More cleanup on paffinity....groan
It is okay to not have a paffinity module IF you aren't using paffinity anyway. So don't error out of MPI_Init because a paffinity module wasn't selected.

Cleanup error reporting in the odls default module to (once and for all!) eliminate messages originating in the fork'd process. Create some new error codes to allow us to pass enough info back to the parent process to provide useful error messages.

2ff1ae13e1 Create a new "heartbeat" module in the sensor framework and move the plm_base heartbeat code there. Add new proc and job states for heartbeat_failed. Remove the "heartbeat" cmd line option for orted as this is now done automatically if the --enable-heartbeat configure option is set.

b9893aacc5 Add a sensor framework to ORTE that monitors applications and notifies the errmgr when they exceed specified boundaries. Two modules are included here:
1. file activity - can monitor file size, access and modification times. If these fail to change over a specified number of sampling iterations (rate is an mca param), then the errmgr is notified.

2. memory usage - checks amount of memory used by a process. Limit and sampling rate can be set.

This support must be enabled by configuring --enable-sensors.

ompi_info and orte-info have been updated to include the new framework.

Also includes some initial steps toward restoring the recovery capability. Most notably, the ODLS API has been extended to include a "restart_proc" entry for restarting a local process, and organizes the various ERRMGR framework globals into a single struct as we do in the other ORTE frameworks. Fix an oversight in the ERRMGR framework where a pointer array was constructed, but not initialized.

Implementation continues.

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

51f64aaf96 Add a new ras module to support bootstrap operations. Additional functionality may eventually be required in the component, but for now all it does is provide a mechanism for ensuring that other allocations don't confuse the system.

509cc0553c When directly launched by an RM, flag that a process is operating without daemons - i.e., standalone. Provide an error string for the new socket_not_available error. Use errmgr.abort to exit when we cannot get a socket, and ensure that the slurmd module returns the proper exit status for slurm 2.0

e7ff2368d6 This fixes trac:1930.
Emit a more informative error message when the file descriptor limit is
reached during an accept() call.  Also, abort when the accept fails to
avoid an infinite loop.

Emit a more informative error message when the help file can't be opened.

bd65f8ba88 Bring in an updated launch system for the orteds. This commit restores the ability to execute singletons and singleton comm_spawn, both in single node and multi-node environments.
Short description: major changes include -

1. singletons now fork/exec a local daemon to manage their operations.

2. the orte daemon code now resides in libopen-rte

3. daemons no longer use the orte triggering system during startup. Instead, they directly call back to their parent pls component to report ready to operate. A base function to count the callbacks has been provided.

I have modified all the pls components except xcpu and poe (don't understand either well enough to do it). Full functionality has been verified for rsh, SLURM, and TM systems. Compile has been verified for xgrid and gridengine.

75d51812a3 Fix the app-failed-to-start capability that was broken by r14554 (holding the caller in rmgr.spawn until the application - as opposed to just the orteds - have started). Allow the rmgr.spawn function to return if the app terminates, correctly handling its return status code to show abnormal termination. Modify orterun to correctly handle the returned status code so it doesn't enter a conditioned wait if the app fails to start since it will never wakeup if it does.

8314e8dbb9 Modify the pernode option so it can accept a request for the number of processes to be launched. We now check three use-cases for pernode:
1. no -np provided - put one proc/node across all allocated nodes

2. -np N provided, N > #nodes - we print a pretty error message and exit

3. -np N provided, N <= #nodes - put one proc/node across N nodes

I also added a new orte constant (ORTE_ERR_SILENT) that allows us to pass up the chain that an error was encountered, but NOT print ORTE_ERROR_LOG messages. This is intended to be used for cases where the error we encounter is NOT an orte error, but rather is one associated with incorrect user input (e.g., the preceding case 2). In such cases, there is no point in printing an ORTE_ERROR_LOG chain of messages as it isn't an orte error.

febc143d8c Per LANL's stated need, add functionality that runs a.out across ALL available process slots if no num_proc is specified on the command line. However, please note the following limitation: we ONLY allow ONE application to be specified on the command line when this feature is invoked. If multiple apps are specified, the user MUST also specify the number to be launched for each and every one of them.
Update the help text to report errors when not following that rule.

Also updated the RMAPS help text to reflect the reorganization of some of the round-robin code into the base.

The new functionality has been tested under Mac OS-X and on Odin using an MPI program. Both byslot and bynode mapping have been checked and verified. Operational support for other systems needs to be verified - I respectfully request people's help in doing so.

3d220cbd48 This patch fixes several issues relating to comm_spawn and N1GE. In particular, it does the following:
1. Modifies the RAS framework so it correctly stores and retrieves the actual slots in use, not just those that were allocated. Although the RAS node structure had storage for the number of slots in use, it turned out that the base function for storing and retrieving that information ignored what was in the field and simply set it equal to the number of slots allocated. This has now been fixed.

2. Modified the RMAPS framework so it updates the registry with the actual number of slots used by the mapping. Note that daemons are still NOT counted in this process as daemons are NOT mapped at this time. This will be fixed in 2.0, but will not be addressed in 1.x.

3. Added a new MCA parameter "rmaps_base_no_oversubscribe" that tells the system not to oversubscribe nodes even if the underlying environment permits it. The default is to oversubscribe if needed and the underlying environment permits it. I'm sure someone may argue "why would a user do that?", but it turns out that (looking ahead to dynamic resource reservations) sometimes users won't know how many nodes or slots they've been given in advance - this just allows them to say "hey, I'd rather not run if I didn't get enough".

4. Reorganizes the RMAPS framework to more easily support multiple components. A lot of the logic in the round_robin mapper was very valuable to any component - this has been moved to the base so others can take advantage of it.

5. Added a new test program "hello_nodename" - just does "hello_world" but also prints out the name of the node it is on.

6. Made the orte_ras_node_t object a full ORTE data type so it can more easily be copied, packed, etc. This proved helpful for the RMAPS code reorganization and might be of use elsewhere too.

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)
