The logs from this branch are much more descriptive than I will put
here (including a *really* long description from last night). Here's
the short version:
- fixed some broken implementations in ras and rmaps
- "orterun --host ..." now works and has clearly defined semantics
(this was the impetus for the branch and all these fixes -- LANL had
a requirement for --host to work for 1.0)
- there is still a little bit of cleanup left to do post-1.0 (we got
correct functionality for 1.0 -- we did not fix bad implementations
that still "work")
- rds/hostfile and ras/hostfile handshaking
- singleton node segment assignments in stage1
- remove the default hostfile (no need for it anymore with the
localhost ras component)
- clean up pls components to avoid duplicate ras mapping queries
- [possible] -bynode/-byslot being specific to a single app context

Some of the functions in opal_init are void or return a bool (opal_output_init, but always returns true.. eh?), so I don't check them.

it's always ORTE_SUCCESS and sometimes masks real !=ORTE_SUCCESS rc
values.
- Add MCA param pls_tm_want_path_check. If nonzero (the default),
check for the orted in the PATH before each tm_spawn()'ing (doing a
little caching so that we don't hammer on the filesystem -- remember
all the PATH's where we successfully found the orted so that we
don't have to query the filesystem multiple times for a PATH where
we previously found the orted)
- Be sure to opal_argv_split() the pls_tm_orted MCA param

will fire some subscriptions that will eventually result in invoking
terminate_job (i.e., terminate anything that may have been
successfully started by launch).

at the moment.
Also remove all references to --map, and (C, N) command line options in the
help file. These references will be put back in when these options are
implemented.

If you use --prefix and then "-x LD_LIBRARY_PATH", the rsh pls would
take great pains to ensure that PATH and LD_LIBRARY_PATH were setup
correctly on the local and remote nodes, but then the fork pls would
blitely overwrite LD_LIBRARY_PATH with what the user exported (i.e.,
most likely without our prefix). This patch takes care of that -- the
fork pls examines the incoming environment, and if it sees PATH or
LD_LIBRARY_PATH, it re-prefixes those variables.

it is possible that if the receive has been arrived the callback will
be called before recv_buffer_nb() returns. This causes deadlock
as we try to acquire the lock, but already hold it.
This was causing orterun and orteds to stall in certian situations.
Became evident when stress testing dynamics with remote nodes.

- Fix bug identified by users: --prefix may also apply on the local
node; we need to prefix the PATH and LD_LIBRARY_PATH environment
variables before invoking execve()

some orted's to stall on locks in the MPI Dynamics cases. Since it
is not essentual that we call these functions, they can so away.
Unlock the peer lock when aborting. This causes a potential deadlock
in do_waitall [see comment in code]. This was causing orteds to
deadlock at times when the seed had terminated. With proper interleaving
and timing the orted was deadlocking. This seems to have fixed this in
my stress testing with MPI 2 Dynamics.
This commit was SVN r7539.
The NS replica should give out tags that are over ORTE_RML_TAG_DYNAMIC
or it will overlap with other outstanding tags. This overlap was killing
MPI_Comm_spawn when a program tried to use it multiple times (> 3).
With this fix MPI_Comm_spawn is behaving properly.
A program can call it many times in a row with out problem.
NOTE: Not tested for multi-threaded build yet

Have the ras_base_schedule_policy MCA parameter working once again. before it
would only do slot based allocation, even if the MCA parameter was set properly.
Currently you can specify to orterun a node allocation by either:
-mca ras_base_schedule_policy node
-bynode
and slot allocation (which is the default) by:
-mca ras_base_schedule_policy slot
-byslot
