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. :-)
Judging by the copyrights on this patch, it's been around for a
while. :-)

Add orte configuration option to control the use of the framework in the system. Although the code will build, it will not be active unless configured with --enable-bootstrap.
If bootstrap is enabled and the new opal_sysinfo framework can successfully determine the cpu model, pass that info to the application as an MCA param to support some work at Sun.
Also, have daemons report back the resources they find to guide process mapping in bootstrap operations (i.e., where the daemon starts at node boot as opposed to being launched at application start).
Adjust some platform files to enable these capabilities.

1. ensure that orte_rmaps_base_schedule_policy does not override cmd line settings
2. when you try to bind to more cores than we have, generate a not-enough-processors error message
3. allow npersocket -bind-to-core combination - because, yes, somebody actually wants to do it.
This commit was SVN r21996.
1. default -npersocket to force -bind-to-socket
2. if we cannot get a value for cores/socket, try using #logical cpus. otherwise, default to 1 core
3. add missing error message for not-enough-processors
4. since we no longer loop through orte_register_params twice, put the auto-detect of
topology info in the rte_init for hnp and std_orted
5. fix bind-to-core, bysocket combination
This commit was SVN r21992.
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. Without the qualifier, the job will abort with an error message indicating that the required functionality is not supported on this system.

1. finalize the logic for properly respecting externally assigned bindings. Thanks to Chris Samuel for his help with this. Still needs some acid testing, but appears to now work.
2. remove the double-logic of requiring opal_paffinity_alone AND bind-to-foo. If the user specifies bind-to-foo, trust her and just do it.

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.

Add ability to store the RM's jobid string to tag the notifier message so that the sys admin knows what job had the problem.
This commit was SVN r21687.
outside the boundaries of the allocated array.
However, the problem is still there. If we have rmaps file containing only
partial information the num_procs get set to the wrong value (the number of
hosts in the rmaps file instead of the number of processes requested on the
command line).

Remove all architecture references from ORTE and put them back in the modex using modex_send/recv calls.
Hetero operations are now fully supported again. Comm_spawn now works up to the point where it segfaults due to an error in the CID code - which now allows Edgar to dig further! :-)
This commit was SVN r21655.
Add a new tm ess module that exploits this capability.
Update the various plm modules to enable it - just a minor change reflecting an added param to a plm base function.
Additional fixes included:
1. remove an erroneous cleanup of session directories in the tool finalize procedure - tools don't create session directories to begin with!
2. fix a duplicate free when attempting to execute a non-existent app
3. cleanup an typo in the comm utilities
4. fix comm_spawn - was perturbed by the changes in pack/unpack of orte_job_t to properly support orte-ps
Been tested on slurm and tm machines, using all tests in orte/test/mpi. May run into issue with command line length on large jobs due to inclusion of node info to support static ports - will fix this next with addition of regexp generator to compress that info.
This commit was SVN r21248.
Unfortunately, we assign the jobid during the plm.spawn procedure - which means it happens -after- control of the job has passed out of the range of mpirun (or whatever program is spawning the job), so it is too late for that main program to register a callback function. If the main program registers tha callback -after- we return from plm.spawn, then it (a) cannot get a callback for failed-to-start, and (b) will miss the callback if a proc aborts in the time between job launch and the call to errmgr.register_callback.
This commit fixes the problem by adding callback-related fields to the orte_job_t object. Thus, the main program can specify what job states should initiate a callback, what function is to be called, and what data is to be passed back by simply filling in the orte_job_t fields prior to calling plm.spawn.
Also, fully implement the "copy" function for the orte_job_t object.
NOTE: as a result of this change, the errmgr.register_callback API may no longer be of any value.
