to make MPI_IN_PLACE (and other sentinel Fortran constants) work on OS
X, we need to use the following compiler (linker) flag:
-Wl,-commons,use_dylibs
So if we're compiling on OS X, test to see if that flag works with the
compiler. If so, add it to the wrapper FFLAGS and FCFLAGS (note that
per a future update, we'll only have one Fortran compiler anyway).
Fixes trac:1982.

Brian dealt with this in the past by creating platform files and using "no-build" to block the components. This was clunky, but acceptable when only one organization was using that option. However, that number has now expanded to at least two more locations.
Accordingly, make --without-rte-support actually work by adding appropriate configury to prevent components from building when they shouldn't. While doing so, remove two frameworks (db and rmcast) that are no longer used as ORCM comes to a close (besides, they belonged in ORCM now anyway). Do some minor cleanups along the way.

not yet sure how and why, but packing a uint8_t with opal_dss lead to
weird values during unpack (except if the original value is already
set to zero).

The wiki page is incomplete at the moment, but I hope to complete it over the next few days. I will provide updates on the devel list. As the wiki page states, the default and most commonly used options remain unchanged (except as noted below). New, esoteric and complex options have been added, but unless you are a true masochist, you are unlikely to use many of them beyond perhaps an initial curiosity-motivated experimentation.
In a nutshell, this commit revamps the map/rank/bind procedure to take into account topology info on the compute nodes. I have, for the most part, preserved the default behaviors, with three notable exceptions:
1. I have at long last bowed my head in submission to the system admin's of managed clusters. For years, they have complained about our default of allowing users to oversubscribe nodes - i.e., to run more processes on a node than allocated slots. Accordingly, I have modified the default behavior: if you are running off of hostfile/dash-host allocated nodes, then the default is to allow oversubscription. If you are running off of RM-allocated nodes, then the default is to NOT allow oversubscription. Flags to override these behaviors are provided, so this only affects the default behavior.
2. both cpus/rank and stride have been removed. The latter was demanded by those who didn't understand the purpose behind it - and I agreed as the users who requested it are no longer using it. The former was removed temporarily pending implementation.
3. vm launch is now the sole method for starting OMPI. It was just too darned hard to maintain multiple launch procedures - maybe someday, provided someone can demonstrate a reason to do so.
As Jeff stated, it is impossible to fully test a change of this size. I have tested it on Linux and Mac, covering all the default and simple options, singletons, and comm_spawn. That said, I'm sure others will find problems, so I'll be watching MTT results until this stabilizes.
This commit was SVN r25476.
Use hwloc to obtain the cpuset for each process during mpi_init, and share that info in the modex. As it arrives, use a new opal_hwloc_base utility function to parse the value against the local proc's cpuset and determine where they overlap. Cache the value in the pmap object as it may be referenced multiple times.
Thus, the return value from orte_ess.proc_get_locality is a 16-bit bitmask that describes the resources being shared with you. This bitmask can be tested using the macros in opal/mca/paffinity/paffinity.h
Locality is available for all procs, whether launched via mpirun or directly with an external launcher such as slurm or aprun.

Don't juse include pre-processor macros between two strins ("s1" #if 0 ... "s2")...
Rather print out the epoch as 0 always...
This commit was SVN r25110.
To enable the epochs and the resilient orte code, use the configure flag:
--enable-resilient-orte
This will define both:
ORTE_ENABLE_EPOCH
ORTE_RESIL_ORTE

Add some debug to nidmap
Ensure that the HNP's node name is not included in the regex when launching via rshbase as that node is automatically included in the daemon map.
This commit was SVN r25063.
Over the course of time, usage of static ports got corrupted in several places, the "parent" info got incorrectly reset, etc. So correct all that and get the regex-based wireup going again.
Also, don't pass node lists if static ports aren't enabled - they are of no value to the orted and just create the possibility of overly-long cmd lines.
This commit was SVN r24860.
Everyone will be starting at MIN anyway (until we implement restart of course)
so there's no reason to set the epoch to INVALID and then immediately reset them
to MIN. This way there's less room to make mistakes later.
This commit was SVN r24829.
So separate out the printing of that key, and let the individual procs generate it in a way that ensures they all get the same result.
This commit was SVN r24646.
Provide a new MCA param that allows the user to direct that we abort the job once a process exits with non-zero status. No recovery is allowed in such cases to avoid trying to restart a process that has already exited MPI.

* If something goes wrong during ompi_mpi_init, don't erroneously
report that it is illegal to invoke MPI_INIT* before MPI_INIT
* Aggregate help messages when possible when something goes wring
during ompi_mpi_init

When called, each mapper checks to see if it can map the job. If npernode is provided, for example, then the loadbalance mapper accepts the assignment and performs the operation - all mappers before it will "pass" as they can't map npernode requests.
Also remove the stale and never completed topo mapper.
This commit was SVN r24393.
Add some new proc/job states
Rename a constant to reflect coming change - remove the arbitrary difference between restarting a proc locally and relocating it to another node in terms of the number of restarts allowed.
Add pretty-print of signals for "proc aborted due to signal" reports.

This means that the converters (opal_err2str, orte_err2str) can now
return NULL as a "silent error". The return value of opal_err2str_fn_t
is the status of the operation (OPAL_SUCCESS or OPAL_ERROR).
This fixes the "Unknown error" message issues on the trunk.
This commit was SVN r24371.
It is statically initialized to the real back-end OPAL show_help
function. During orte_show_help_init(), the variable is re-assigned
with the value of the back-end ORTE show_help function (the one that
does error message aggregation).
Therefore, anything that calls opal_show_help() after a certain point
in orte_init() will have their show_help messages be aggregated.
w00t! Even code down in OPAL -- that has no knowledge of ORTE -- will
have their messages aggregated. '''Double w00t!'''
During orte_show_help_finalize(), we restore the original pointer
value so that it something calls opal_show_help() after
orte_finalize(), it'll still work properly (but it won't be
aggregated).

Note: the ompi_check_libfca.m4 file had to be modified to avoid it stomping on global CPPFLAGS and the like. The file was also relocated to the ompi/config directory as it pertains solely to an ompi-layer component.
Forgive the mid-day configure change, but I know Shiqing is working the windows issues and don't want to cause him unnecessary redo work.

Setup the event API to support multiple bases in preparation for splitting the OMPI and ORTE events. Holding here pending shared memory resolution.
