Oversubscribe stipulates that we allow more procs on the node than assigned slots - it has nothing to do with the number of available pe's. Let overload directives handle the pe situation.
Each process occupies a "slot". We automatically set #slots = #cpus if nothing else is told to us. If you want to run more procs and slots, you must tell us to allow oversubscription.
A process can utilize multiple pe's if that option is given. If you try to bind more than one proc to a given pe, then we will error out unless you tell us to allow overloading.
We need to list all major project libraries in the private libraries
line to enable static linking to work properly.

Don't strcmp against the default value -- the default value may change
over time. Instead, check to see if the MCA var source is not
DEFAULT.

Split process name variable "name" to
- "wildcard_rank" for the cases where wildcard is used.
- "pname" for the case where reference to particular process is needed.

Note that this cannot be used for MPI performance testing. It is really only useful for ORTE scaling tests. It also only works with the rsh/ssh launcher.
If requested, obtain stacktraces for each application process and report it to stderr upon timeout
stack traces: minor improvements
- Also include the hostname and PID of the each process for which
we're sending the stack traces (vs. just including the ORTE process
name)
- Send a specific error message if we couldn't find "gstack" in the
$PATH (e.g., on OS X)
- Send a sepcific error message if gstack fails to run
- Print a message that obtaining the stack traces may take a few
seconds so that users don't wonder what's happening

It is verbotten to use opal_output() after the fork() but before the
exec()! It results in all manner of undefined behavior. For example,
on some OS X systems, if you run a trivial "hello world" MPI program
with a high level of ODLS verbosity:
```sh
$ mpirun -np 3 --mca odls_base_verbose 100 ./hello_c
```
You will see a bunch of output from the mpirun ODLS base, but then it
*may* hang in odls_default_module.c:do_child() -- after the fork() but
before the exec() -- while trying to opal_output() some debugging
statements.
The solution is to remove these extraneous opal_output() statements.
Indeed, the ODLS base is already outputting the same information that
these opal_output() statements are trying to emit, anyway.

Take another shot at untangling the spaghetti
orterun: fix for command line parsing
orte-submit calls opal_init_util () before parsing out MCA command line
options (-mca, -am, etc). This prevents mpirun from setting opal MCA
variables for some frameworks as well as the MCA base. This is because
when a framework is opened all of its variables are set to read-only.
Eventually we want to lift this restriction on some MCA variables but
since -mca is affected we must parse out the MCA command line options
before opal_init_util(). This commit fixes the bug by adding a new
option to opal_cmd_line_parse (ignore unknown option) so orte-submit
can pre-parse the command line for MCA options.

Have OMPI's current version of pmix120 nicely fail in case of
too long sun_path (longer than 108 or in case of OSX 103 chars).
And have OMPI return proper error messages with hints how to
amend.
so usock_peer_create_socket know it must re-create the socket
/* assuming it is ever supposed to occur */
also fix a typo (peer->sd >= 0) in usock_peer_create_socket
Ensure the returned exit status is non-zero if we fail to map
If no -np is given, but either -host and/or -hostfile was given, then error out with a message telling the user that this combination is not supported.
If -np is given, and -host is given with only one instance of each host, then default the #slots to the detected #pe's and enforce oversubscription rules.
If -np is given, and -host is given with more than one instance of a given host, then set the #slots for that host to the number of times it was given and enforce oversubscription rules. Alternatively, the #slots can be specified via "-host foo:N". I therefore believe that row #7 on Jeff's spreadsheet is incorrect.
With that one correction, this now passes all the given use-cases on that spreadsheet.
Make things behave under unmanaged allocations more like their managed cousins - if the #slots is given, then no-np shall fill things up.
Fixes#1344
This reverts commit open-mpi/ompi@f7257a8310.
Ensure that we properly cleanup the session directory tree. Prior code had issues with symlinks, especially if the file that the link points to was already removed as we traverse the tree. Also found that the dirent checks for directory type weren't fully portable, and so fall back to the stat-based approach which is known to be portable.
Fix singularity singletons by detecting we are in a container and properly setting the pmix selection to pick the isolated component. Remove a stale restriction blocking use of the sm btl
Turns out there are some cases where the Cray
wlm_detect_get_active may return NULL, in which
case fallback to wlm_detect_get_default method
is suggested. Make use of the fallback to
avoid segfaults under some circumstances in the
ALPS plm selection method.

* qos framework is moving to the scon layer and is no longer required in ORTE
* remove the rml/ftrm component as we now have multiple active components, and so the wrapper needs to be rethought
* no need for separating the "base" from "API" module definition. The two are identical
* move the "stub" functions into their own file for cleanliness
* general cleanup to meet coding standards
* cleanup some logic in the stubs
* provide a more reliable way of determining that a process is a singleton by leveraging the schizo framework. Add new components for slurm, alps, and orte to detect when we are in a managed environment, and if we have been launched by mpirun or a native launcher. Set the correct envars to control ess and pmix selection in each case.
* change the relative priority of the pmix120 and pmix112 components to make pmix120 the default
* fix singleton comm-spawn by correctly setting the num_apps field of the orte_job_t created by the daemon - this fixes a segfault in register_nspace on newly created daemons
* ensure orterun doesn't propagate any ess or pmix directives in its environment
* Cleanup a few valgrind issues and memory leaks
* Fix a race condition that prevented the client from completing notification registrations (missing thread shift)
* Ensure the shizo/alps component detects launch by mpirun
There is a bug in MPMD detection that disables totalview if a : is
found anywhere on the command line. This includes inside an argument
option or MCA variable value. This commit changes the check to look
for the string " : " instead of the character : which should eliminate
the issue in most cases.
