"make distclean". It's not clear whether it's an Automake bug or
whether what I did simply is not supported (I've got pending mail into
Ralf W. asking about it). The short version is that during "make
distclean", ompi/mpi/f77/Makefile would rm -rf ompi/mpi/f77/.deps.
But ompi/Makefile still include's some .Plo files from that directory,
so Bad Things happened when "make distclean" unrolled from the
ompi/mpi/f77 dir back up to the ompi/ dir.
So I went with George's original suggestion and moved the f77 "base"
files in question into a new directory: ompi/mpi/f77/base and put a
Makefile.include in there. That way, this directory is not traversed
twice by distclean, and .deps is only removed when it is supposed to
be. Maybe we'll be able to do it a little better someday, but that's
the way it is now.
I'll check this with a fresh checkout once this is committed to SVN as
well; some of these kinds of problems don't show up until you do a
build from a completely fresh SVN checkout.

Update the version of ROMIO to that which was contained in

(because OMPI uses a few code paths in ROMIO that MPICH2 does not;
there were a few compile bugs in the ROMIO from MPICH2-1.0.7).
Added an info MCA param to be able to tell which version of ROMIO is

are properly linked against libmpi.la.
This required a little creative AM usage, inspired by discussion on
OMPI devel list:
* Make a new ompi/mpi/f77/Makefile_f77base.include; effectively move
the building of the f77 "base" glue stuff (libmpi_f77base.la) into
this Makefile and away from ompi/mpi/f77/Makefile.am. The sources
in question require some specific CPPFLAGS, so we couldn't just add
the raw sources into libmpi_la_SOURCES, unfortunately.
* Include this new Makefile in the top-level ompi/Makefile.am
* The libmpi_f77base.la LT convenience library was already sucked
into libmpi.la; breaking it out into its own Makefile allows us
to build it earlier and therefore complete buidling libmpi.la
earlier.
* Side effect: the ompi/mpi/Makefile.am is now mostly unnecessary; it
no longer specifies a SUBDIRS for each of the bindings directories
to traverse into (since they are now in the top-level SUBDIRS). As
such, the man pages are now also now included in the top-level
ompi/Makefile.am.
The end of the result is that libmpi.la -- including a few sources
from mpi/f77 -- is fully built before the C++, F77, and F90 bindings
are built. Therefore, the C++, F77, and F90 bindings libraries can
all link against libmpi.la.

Short version: remove opal_paffinity_alone and restore
mpi_paffinity_alone. ORTE makes various information available for the
MPI layer to decide what it wants to do in terms of processor
affinity.
Details:
* remove opal_paffinity_alone MCA param; restore mpi_paffinity_alone
MCA param
* move opal_paffinity_slot_list param registration to paffinity base
* ompi_mpi_init() calls opal_paffinity_base_slot_list_set(); if that
succeeds use that. If no slot list was set, see if
mpi_paffinity_alone was set. If so, bind this process to its Node
Local Rank (NLR). The NLR is the ORTE-maintained slot ID; if you
COMM_SPAWN to a host in this ORTE universe that already has procs
on it, the NLR for the new job will start at N (not 0). So this is
slightly better than mpi_paffinity_alone in the v1.2 series.
* If a slot list is specified *and* mpi_paffinity_alone is set, we
display an error and abort.
* Remove calls from rmaps/rank_file component to register and lookup
opal_paffinity mca params.
* Remove code in orte/odls that set affinities - instead, have them
just pass a slot_list if it exists.
* Cleanup the orte/odls code that determined
oversubscribed/want_processor as these were just opposites of each
other.

If IBCM was explicitly specified with exclude/include parameter,
OpenIB BTL will enable verbose report for "/dev/infiniband/ucm" error,
other way the error will not be reported.
This commit was SVN r18868.
Lenny and I went back and forth on whether we should simply register
another "mpi_paffinity_alone" MCA param and then try to figure out
which one was set in ompi_mpi_init, but there was difficulty in
figuring out what to do. So it seemed like the Right Thing to do was
to implement what was committed in r18770; then we could tell where
MCA parameters were set from and you could do Better Things (this is
also useful in the openib BTL, where parameters can be set either via
MCA parameter or via an INI file).
But after that was done, it seemed only a few steps further to
actually implement two new features in the MCA params area:
* Synonyms (where one MCA param name is a synonym for another)
* Allow MCA params and/or their synonyms to be marked as "deprecated"
(printing out warnings if they are used)
These features have actually long been discussed/desired, and I had
some time in airports and airplanes recently where I could work in
this stuff on a standalone laptop. So I did it. :-)
This commit introduces these two new features, and then uses them to
register mpi_paffinity_alone as a non-deprecated synonym for
opal_paffinity_alone. A few other random points in this commit:
* Add a few error checks for conditions that were not checked before
* Correct some comments in mca_base_params.h
* Add a few comments in strategic places
* ompi_info now prints additional information:
* for any MCA parameter that has synonyms, it lists all the
synonyms
* synonyms are also output as 1st-class MCA params, but with an
additional attribute indicating that they have a "parent"
* all MCA param name (both "real" or "synonym") will output an
attribute indicating whether it is deprecated or not. A synonym
is deprecated if it iself is marked as deprecated (via the
mca_base_param_regist_syn() or mca_base_param_register_syn_name()
functions) or if its "parent" MCA parameter is deprecated

With help from Brian, modify the ompi/proc/proc.c code to be more thread-safe. Remove the list operations from the ompi_proc_t constructor and destructor. Insert list appends to ompi_proc_init and ompi_proc_find_and_add as required, and protect those with thread locks. Let only the ompi_proc_finalize function actually remove objects from the ompi_proc_list.
Cleanup a few places where functions might return without unlocking a thread. Ensure the ompi_proc_world also does an OBJ_RETAIN so that the reference count on any subsequently released object is correct.

1. repair of the linear and direct routed modules
2. repair of the ompi/pubsub/orte module to correctly init routes to the ompi-server, and correctly handle failure to correctly parse the provided ompi-server URI
3. modification of orterun to accept both "file" and "FILE" for designating where the ompi-server URI is to be found - purely a convenience feature
4. resolution of a message ordering problem during the connect/accept handshake that allowed the "send-first" proc to attempt to send to the "recv-first" proc before the HNP had actually updated its routes.
Let this be a further reminder to all - message ordering is NOT guaranteed in the OOB
5. Repair the ompi/dpm/orte module to correctly init routes during connect/accept.
Reminder to all: messages sent to procs in another job family (i.e., started by a different mpirun) are ALWAYS routed through the respective HNPs. As per the comments in orte/routed, this is REQUIRED to maintain connect/accept (where only the root proc on each side is capable of init'ing the routes), allow communication between mpirun's using different routing modules, and to minimize connections on tools such as ompi-server. It is all taken care of "under the covers" by the OOB to ensure that a route back to the sender is maintained, even when the different mpirun's are using different routed modules.
6. corrections in the orte/odls to ensure proper identification of daemons participating in a dynamic launch
7. corrections in build/nidmap to support update of an existing nidmap during dynamic launch
8. corrected implementation of the update_arch function in the ESS, along with consolidation of a number of ESS operations into base functions for easier maintenance. The ability to support info from multiple jobs was added, although we don't currently do so - this will come later to support further fault recovery strategies
9. minor updates to several functions to remove unnecessary and/or no longer used variables and envar's, add some debugging output, etc.
10. addition of a new macro ORTE_PROC_IS_DAEMON that resolves to true if the provided proc is a daemon
There is still more cleanup to be done for efficiency, but this at least works.
Tested on single-node Mac, multi-node SLURM via odin. Tests included connect/accept, publish/lookup/unpublish, comm_spawn, comm_spawn_multiple, and singleton comm_spawn.

But we need to figure out how to determine a good value for the
resident adapter(s) at runtime. It's problematic because, for
example, Mellanox ConnectX and Chelsio T3 report max_inline values
differently at run-time. If you ibv_create_qp with a max_inline value

other values (e.g., max_send_sge and max_recv_sge). But T3 always
reports back "64".
We're looking into this to figure out the best way -- reducing the
default right now should allow other adapters to run while we figure
it out.

After much work by Jeff and myself, and quite a lot of discussion, it has become clear that we simply cannot resolve the infinite loops caused by RML-involved subsystems calling orte_output. The original rationale for the change to orte_output has also been reduced by shifting the output of XML-formatted vs human readable messages to an alternative approach.
I have globally replaced the orte_output/ORTE_OUTPUT calls in the code base, as well as the corresponding .h file name. I have test compiled and run this on the various environments within my reach, so hopefully this will prove minimally disruptive.

1. The send path get shorter. The BTL is allowed to return > 0 to specify that the
descriptor was pushed to the networks, and that the memory attached to it is
available again for the upper layer. The MCA_BTL_DES_SEND_ALWAYS_CALLBACK flag
can be used by the PML to force the BTL to always trigger the callback.
Unmodified BTL will continue to work as expected, as they will return OMPI_SUCCESS
which force the PML to have exactly the same behavior as before. Some BTLs have
been modified: self, sm, tcp, mx.
2. Add send immediate interface to BTL.
The idea is to have a mechanism of allowing the BTL to take advantage of
send optimizations such as the ability to deliver data "inline". Some
network APIs such as Portals allow data to be sent using a "thin" event
without packing data into a memory descriptor. This interface change
allows the BTL to use such capabilities and allows for other optimizations

non-empty. If not, then exit the openib btl silently. This addresses
the case where libibverbs is installed (which is getting more common)
and therefore the openib BTL was built/installed, but the kernel
drivers are not loaded (assumedly because there is no RDMA hardware
present). In this case, "mpirun a.out" will not issue a warning.
There appears to be no good way to definitely tell if there are no
RDMA hardware devices present. For example, if libibverbs/the openib
BTL is installed, there are no RDMA devices present, but the RDMA
hardware kernel drivers ''are'' loaded, OMPI will warn that it was
unable to find suitable devices. This warning is easily eliminated by
unloading the kernel drivers.

By consolidating them all into one function, ompi_info can call that function and register the desired variables. This also requires, however, that ompi_info call orte_output_init to avoid generating tons of error messages, so make that adjustment too.
Fixes ticket #1314
In addition, orte_output has a race condition issue whereby calls to orte_output/verbose can occur prior to either the RML being defined/setup, or the HNP being defined. This latter occurs during the initialization of the orte_process_info structure. In both cases, there is no way orte_output can send the output to the HNP. Hence, the message must be simply output locally.

with something with a different size ... well we segfault. The reason was
that the logic in the PML OB1 call the convertor based on the length
of he data on the wire and not the length of the data that the receiver
expects.
In other words, this is only half a patch :) It fix the problem, but we
still have to make sure the unpack is not called at all when the receiver
expect ZERO bytes.

* allow receive_queues to be specified in the INI file
* detect when multiple different receive_queues are specified and
gracefully abort
However, accomplishing these goals ran into multiple difficulties. By
putting receive_queues in the INI file:
1. we may not find the value until we've already traversed multiple HCAs
1. we may find multiple different receive_queues values
But since the openib btl initializes as it discovers each HCA/port/LID
(including the BSRQ data), if we find a new receive_queues value late
in the discovery process, then all the BSRQ data that was previously
initialized will likely be invalid. So I had to pull all the BSRQ
initialization out until after the rest of the discovery /
initialization process.
Additionally, note that if the user specifies the MCA parameter
btl_openib_receive_queues, it trumps whatever was in the INI file. So
in this case, there can never be a receive_queues conflict. This
commit does the following (Jon wrote part of this, too):
* adapt _ini.c to accept the "receive_queues" field in the file
* move 90% of _setup_qps() from _ini.c to _component.c
* move what was left of _setup_qps() into the main
_register_mca_params() function
* adapt init_one_hca() to detect conflicting receive_queues values
from the INI file
* after the _component.c loop calling init_one_hca():
* call setup_qps() to parse the final receive_queues string value
* traverse all resulting btls and initialize their HCAs (if they
weren't already): setup some lists and call prepare_hca_for_use()
I tested this code on a dual-HCA system where I artificially put in
differing receive_queues values in the INI file for the two different
types of HCAs that I have and it all seemed to work.

= ORTE Job-Level Output Messages =
Add two new interfaces that should be used for all new code throughout
the ORTE and OMPI layers (we already make the search-and-replace on
the existing ORTE / OMPI layers):
* orte_output(): (and corresponding friends ORTE_OUTPUT,
orte_output_verbose, etc.) This function sends the output directly
to the HNP for processing as part of a job-specific output
channel. It supports all the same outputs as opal_output()
(syslog, file, stdout, stderr), but for stdout/stderr, the output
is sent to the HNP for processing and output. More on this below.
* orte_show_help(): This function is a drop-in-replacement for
opal_show_help(), with two differences in functionality:
1. the rendered text help message output is sent to the HNP for
display (rather than outputting directly into the process' stderr
stream)
1. the HNP detects duplicate help messages and does not display them
(so that you don't see the same error message N times, once from
each of your N MPI processes); instead, it counts "new" instances
of the help message and displays a message every ~5 seconds when
there are new ones ("I got X new copies of the help message...")
opal_show_help and opal_output still exist, but they only output in
the current process. The intent for the new orte_* functions is that
they can apply job-level intelligence to the output. As such, we
recommend that all new ORTE and OMPI code use the new orte_*
functions, not thei opal_* functions.
=== New code ===
For ORTE and OMPI programmers, here's what you need to do differently
in new code:
* Do not include opal/util/show_help.h or opal/util/output.h.
Instead, include orte/util/output.h (this one header file has
declarations for both the orte_output() series of functions and
orte_show_help()).
* Effectively s/opal_output/orte_output/gi throughout your code.
Note that orte_output_open() takes a slightly different argument
list (as a way to pass data to the filtering stream -- see below),
so you if explicitly call opal_output_open(), you'll need to
slightly adapt to the new signature of orte_output_open().
* Literally s/opal_show_help/orte_show_help/. The function signature
is identical.
=== Notes ===
* orte_output'ing to stream 0 will do similar to what
opal_output'ing did, so leaving a hard-coded "0" as the first
argument is safe.
* For systems that do not use ORTE's RML or the HNP, the effect of
orte_output_* and orte_show_help will be identical to their opal
counterparts (the additional information passed to
orte_output_open() will be lost!). Indeed, the orte_* functions
simply become trivial wrappers to their opal_* counterparts. Note
that we have not tested this; the code is simple but it is quite
possible that we mucked something up.
= Filter Framework =
Messages sent view the new orte_* functions described above and
messages output via the IOF on the HNP will now optionally be passed
through a new "filter" framework before being output to
stdout/stderr. The "filter" OPAL MCA framework is intended to allow
preprocessing to messages before they are sent to their final
destinations. The first component that was written in the filter
framework was to create an XML stream, segregating all the messages
into different XML tags, etc. This will allow 3rd party tools to read
the stdout/stderr from the HNP and be able to know exactly what each
text message is (e.g., a help message, another OMPI infrastructure
message, stdout from the user process, stderr from the user process,
etc.).
Filtering is not active by default. Filter components must be
specifically requested, such as:
{{{
$ mpirun --mca filter xml ...
}}}
There can only be one filter component active.
= New MCA Parameters =
The new functionality described above introduces two new MCA
parameters:
* '''orte_base_help_aggregate''': Defaults to 1 (true), meaning that
help messages will be aggregated, as described above. If set to 0,
all help messages will be displayed, even if they are duplicates
(i.e., the original behavior).
* '''orte_base_show_output_recursions''': An MCA parameter to help
debug one of the known issues, described below. It is likely that
this MCA parameter will disappear before v1.3 final.
= Known Issues =
* The XML filter component is not complete. The current output from
this component is preliminary and not real XML. A bit more work
needs to be done to configure.m4 search for an appropriate XML
library/link it in/use it at run time.
* There are possible recursion loops in the orte_output() and
orte_show_help() functions -- e.g., if RML send calls orte_output()
or orte_show_help(). We have some ideas how to fix these, but
figured that it was ok to commit before feature freeze with known
issues. The code currently contains sub-optimal workarounds so
that this will not be a problem, but it would be good to actually
solve the problem rather than have hackish workarounds before v1.3 final.
