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

help-orterun.txt: minor tweaks
Trivial update: show "--timeout" (instead of "-timeout") in the help
message, just to encourage the use of double-dash options.

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.

These macros should really be named OPAL_SUMMARY_*; they're used in
all projects, and therefore should be in the lowest later project (OPAL).

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.
