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.
This commit was SVN r23764.
All interface APIs for accessing the info remain unchanged in opal/util/if.c.
This has been tested on Mac, Linux, and NetBSD. Nobody else seemed interested in testing it, so there may be some future problems revealed as people try it on other OSs.

Major Changes:
--------------
* Added C/R-enabled Debugging support.
Enabled with the --enable-crdebug flag. See the following website for more information:
http://osl.iu.edu/research/ft/crdebug/
* Added Stable Storage (SStore) framework for checkpoint storage
* 'central' component does a direct to central storage save
* 'stage' component stages checkpoints to central storage while the application continues execution.
* 'stage' supports offline compression of checkpoints before moving (sstore_stage_compress)
* 'stage' supports local caching of checkpoints to improve automatic recovery (sstore_stage_caching)
* Added Compression (compress) framework to support
* Add two new ErrMgr recovery policies
* {{{crmig}}} C/R Process Migration
* {{{autor}}} C/R Automatic Recovery
* Added the {{{ompi-migrate}}} command line tool to support the {{{crmig}}} ErrMgr component
* Added CR MPI Ext functions (enable them with {{{--enable-mpi-ext=cr}}} configure option)
* {{{OMPI_CR_Checkpoint}}} (Fixes trac:2342)
* {{{OMPI_CR_Restart}}}
* {{{OMPI_CR_Migrate}}} (may need some more work for mapping rules)
* {{{OMPI_CR_INC_register_callback}}} (Fixes trac:2192)
* {{{OMPI_CR_Quiesce_start}}}
* {{{OMPI_CR_Quiesce_checkpoint}}}
* {{{OMPI_CR_Quiesce_end}}}
* {{{OMPI_CR_self_register_checkpoint_callback}}}
* {{{OMPI_CR_self_register_restart_callback}}}
* {{{OMPI_CR_self_register_continue_callback}}}
* The ErrMgr predicted_fault() interface has been changed to take an opal_list_t of ErrMgr defined types. This will allow us to better support a wider range of fault prediction services in the future.
* Add a progress meter to:
* FileM rsh (filem_rsh_process_meter)
* SnapC full (snapc_full_progress_meter)
* SStore stage (sstore_stage_progress_meter)
* Added 2 new command line options to ompi-restart
* --showme : Display the full command line that would have been exec'ed.
* --mpirun_opts : Command line options to pass directly to mpirun. (Fixes trac:2413)
* Deprecated some MCA params:
* crs_base_snapshot_dir deprecated, use sstore_stage_local_snapshot_dir
* snapc_base_global_snapshot_dir deprecated, use sstore_base_global_snapshot_dir
* snapc_base_global_shared deprecated, use sstore_stage_global_is_shared
* snapc_base_store_in_place deprecated, replaced with different components of SStore
* snapc_base_global_snapshot_ref deprecated, use sstore_base_global_snapshot_ref
* snapc_base_establish_global_snapshot_dir deprecated, never well supported
* snapc_full_skip_filem deprecated, use sstore_stage_skip_filem
Minor Changes:
--------------
* Fixes trac:1924 : {{{ompi-restart}}} now recognizes path prefixed checkpoint handles and does the right thing.
* Fixes trac:2097 : {{{ompi-info}}} should now report all available CRS components
* Fixes trac:2161 : Manual checkpoint movement. A user can 'mv' a checkpoint directory from the original location to another and still restart from it.
* Fixes trac:2208 : Honor various TMPDIR varaibles instead of forcing {{{/tmp}}}
* Move {{{ompi_cr_continue_like_restart}}} to {{{orte_cr_continue_like_restart}}} to be more flexible in where this should be set.
* opal_crs_base_metadata_write* functions have been moved to SStore to support a wider range of metadata handling functionality.
* Cleanup the CRS framework and components to work with the SStore framework.
* Cleanup the SnapC framework and components to work with the SStore framework (cleans up these code paths considerably).
* Add 'quiesce' hook to CRCP for a future enhancement.
* We now require a BLCR version that supports {{{cr_request_file()}}} or {{{cr_request_checkpoint()}}} in order to make the code more maintainable. Note that {{{cr_request_file}}} has been deprecated since 0.7.0, so we prefer to use {{{cr_request_checkpoint()}}}.
* Add optional application level INC callbacks (registered through the CR MPI Ext interface).
* Increase the {{{opal_cr_thread_sleep_wait}}} parameter to 1000 microseconds to make the C/R thread less aggressive.
* {{{opal-restart}}} now looks for cache directories before falling back on stable storage when asked.
* {{{opal-restart}}} also support local decompression before restarting
* {{{orte-checkpoint}}} now uses the SStore framework to work with the metadata
* {{{orte-restart}}} now uses the SStore framework to work with the metadata
* Remove the {{{orte-restart}}} preload option. This was removed since the user only needs to select the 'stage' component in order to support this functionality.
* Since the '-am' parameter is saved in the metadata, {{{ompi-restart}}} no longer hard codes {{{-am ft-enable-cr}}}.
* Fix {{{hnp}}} ErrMgr so that if a previous component in the stack has 'fixed' the problem, then it should be skipped.
* Make sure to decrement the number of 'num_local_procs' in the orted when one goes away.
* odls now checks the SStore framework to see if it needs to load any checkpoint files before launching (to support 'stage'). This separates the SStore logic from the --preload-[binary|files] options.
* Add unique IDs to the named pipes established between the orted and the app in SnapC. This is to better support migration and automatic recovery activities.
* Improve the checks for 'already checkpointing' error path.
* A a recovery output timer, to show how long it takes to restart a job
* Do a better job of cleaning up the old session directory on restart.
* Add a local module to the autor and crmig ErrMgr components. These small modules prevent the 'orted' component from attempting a local recovery (Which does not work for MPI apps at the moment)
* Add a fix for bounding the checkpointable region between MPI_Init and MPI_Finalize.

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.

Since the MPIR symbols are now included in the ORTE library, remove duplicate declarations in OMPI and replace them with extern references to their ORTE instantiations.

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.
This commit was SVN r23300.
Modify the debugger control flag to include "do not monitor" so orterun will not take debugger daemon termination into account when deciding that all jobs are done.
This commit was SVN r23282.
* Remove OPAL_ERR_PAFFINITY_NOT_SUPPORTED; fit it into the generic
OPAL_ERR_NOT_SUPPORTED case.
* When odls_default detects that processor affinity is not supported,
it prints a specific message about it, and then it suppressed a
generic HNP help message that would normally follow it (i.e., it's
easier to have the "processor affinity is not supported" show_help
message last).
* Use some symbolic names in odls_default instead of fixed int's,
just for slight readability improvements in the code.
* Introduce orte_show_help_suppress(), which gives the ability to
suppress any future showings of any arbitrary show_help() message.
This is useful if you display message X and want to suppress
message Y. This suppression *only* works in environments where
orte_show_help() does coalescing.
This commit was SVN r23249.
(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.
This commit was SVN r23162.
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.

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.

1. orte_enable_recovery - default recovery policy, can be overridden on a per-job basis
2. orte_max_local_restarts - default max number of local restarts, can be overridden
3. orte_max_global_restarts - default max number of relocates, can be overridden
Implement the restart_proc API for the ODLS framework, reorganize the default fns a little to avoid copying code.
This commit was SVN r23057.
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.
This commit was SVN r23043.
* 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

friends also receive &argc and &argv (George asked Jeff to Ralph to
review before committing). The thought is that passing argv and argc
to opal/orte_init be useful to other projects outside of OMPI that are
using OPAL and/or ORTE (especially in conjunction with some other
bootstrapping code where it is helpful to modify argv). It's such a
small thing that it's easy to apply here to make others' lives a
little easier.
Ask George for more details; I'm just the messenger. :-)

Other items in this commit are mostly cleanup that has been sitting off-trunk for too long:
* Add a new {{{opal_crs_base_ckpt_options_t}}} type that encapsulates the various options that could be passed to the CRS. Currently only TERM and STOP, but this makes adding others ''much'' easier.
* Eliminate ORTE_SNAPC_CKPT_STATE_PENDING_TERM, since it served a redundant purpose with the new options type.
* Lay some basic ground work for some future features.

The new options work by adding an ":if-avail" qualifier to the "bind-to-socket" and "bind-to-core" MCA params. If the system does not support this capability, the job will launch anyway.

Add a capability to parse the rankfile to extract node information in place of requiring both hostfile and rankfile for non-RM managed environments. The rankfile is -only- parsed for this IF the hostfile and -host options are not given. Otherwise, those are used to establish allocation info as we did before this commit.
This commit was SVN r21815.
Adds several new mpirun options:
* -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding.
* -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned.
* -bind-to-core - currently the default behavior (maintained from prior default)
* -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile
Similar features/options are provided at the board level for multi-board nodes.

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.
This commit was SVN r21203.
* Pass the sequence number of the checkpoint along with reference from the global to the local coordinator.
* 'orte-restart --apponly' now just generates the app context file, and does not run with it. This provides the user the ability to edit the file before launching.
* Add a OPAL_CRS_NONE state
* Split the INC into three distinct parts.
* Implement a restart mechanism for the 'none' component. If given a context it simply execvp()'s it.
This commit was SVN r21195.
* Add 'orte-checkpoint -l' option that lists all checkpoints currently available on the system.
* Add 'orte-restart -i' which prints information regarding the checkpoint targeted for restart.

* Improved timing in SnapC Full Global Coordinator
* Improved scalability of the SnapC Full protocol
* Minor improvements to the error reporting mechanisms in SnapC and FileM
* Improved the memory usage of the metadata routines - now the owner of the data is more explicit.
* Added a FileM hint to indicate when files stored locally can be moved to/from a globally mounted file system using just the 'cp' command instead of the 'rcp/scp' command. Slightly improves performance, but not too drastically. Can be set using the following SnapC MCA parameter: {{{snapc_base_global_shared=1}}}
* Implement the ability to throttle the number of outgoing connections in FileM. At larger scales this type of explicit throttling helps prevent overwhelming the HNP machine. Default: 10, set via MCA parameter: {{{filem_rsh_max_outgoing}}}
* Add a few diagnostic/debugging features to SnapC and FileM.

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.
