onto the backend daemons. By default, let mpirun only pack the app_context
info and send that to the backend daemons where the mapping will
be done. This significantly reduces the computational time on mpirun as it isn't
running up/down the topology tree computing thousands of binding
locations, and it reduces the launch message to a very small number of
bytes.
When running -novm, fall back to the old way of doing things
where mpirun computes the entire map and binding, and then sends
the full info to the backend daemon.
Add a new cmd line option/mca param --fwd-mpirun-port that allows
mpirun to dynamically select a port, but then passes that back to
all the other daemons so they will use that port as a static port
for their own wireup. In this mode, we no longer "phone home" directly
to mpirun, but instead use the static port to wireup at daemon
start. We then use the routing tree to rollup the initial
launch report, and limit the number of open sockets on mpirun's node.
Update ras simulator to track the new nidmap code
Cleanup some bugs in the nidmap regex code, and enhance the error message for not enough slots to include the host on which the problem is found.
Update gadget platform file
Initialize the range count when starting a new range
Fix the no-np case in managed allocation
Ensure DVM node usage gets cleaned up after each job
Update scaling.pl script to use --fwd-mpirun-port. Pre-connect the daemon to its parent during launch while we are otherwise waiting for the daemon's children to send their "phone home" rollup messages

Per a prior commit, the presence of "hwloc.h" can cause ambiguity when
using --with-hwloc=external (i.e., whether to include
opal/mca/hwloc/hwloc.h or whether to include the system-installed
hwloc.h).
This commit:
1. Renames opal/mca/hwloc/hwloc.h to hwloc-internal.h.
2. Adds opal/mca/hwloc/autogen.options to tell autogen.pl to expect to
find hwloc-internal.h (instead of hwloc.h) in opal/mca/hwloc.
3. s@opal/mca/hwloc/hwloc.h@opal/mca/hwloc/hwloc-internal.h@g in the
rest of the code base.

This fixes a mismatch between PS listing that returned
USERNAME but code was pruning based on UID.
This changes the OPAL_PS_FLAVOR_CHECK format to return
'uid' instead of 'user'. (Note: Avoiding call to
getlogin_r() but assuming UID is uniform on system,
same assumption exists for session dir anyway.)
Note, still maintains behavior from man page for root
running orte-clean on node (kills all orteds).
Adds 'orte-dvm' to list of procnames that will be checked/killed.

Add ability to pass DVM URI purely via environment
to simplify invocation from command-line (e.g., start dvm,
export URI, mpirun w/o needing to add `--hnp` arg).
If user passes both envvar *and* cmdline, the cmdline wins.

Need to check the entire value instead of just the last N digits. Otherwise, "-host 15" will match nid0015, nid0115, and any other launch id ending in 15
It appears strtol can return either a NULL or a zero-length string, so check for both cases

This update should fix the mpirun man page so all
mpirun command line options are included, and
mpirun commands that have been removed are no
longer in the man page. I also fixed some of
the file formatting, and bolding of command
parameters.

Allow someone to specify the "pe=N" modifier to a mapping policy when N=1. This equates to just "bind-to core", but helps people who use a script to set the PE policy. Fix a bug where setting the binding policy left a lingering "if-supported" flag that shouldn't be there.

Set the orte_bound_at_launch MCA variable. This resolves a launch

* Similar to the other launchers (i.e., slurm, alps) we need to put the
children in a separate process group to prevent SIGINT (from a CTRL-C)
from being delivered to the whole process group and prematurely
killing the rsh/ssh connections to the remote daemons.

This commit fixes an error in teardown where the event bases are town
down before the peer structures are released. This causes us to call
event_del on an invalid event base. At best this makes valgrind
complain and at worst this causes aborts or segvs.

Setting to <= 0 will cause it to wait forever

Since the oob and connections systems do not work the same way they
did in older versions of Open MPI these operations are no longer
necessary. At best they do nothing and at worst they hurt performance
by making us enter the event library more often in opal_progress().
