1. We can't use orte_output in the CPC service thread because orte is
not thread safe
1. Use the macro version sso that they're compiled out of production

* 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.

There are more details in the code regarding how to use this feature.
Also shift a few of the orte_output back to opal_output. I'm experiencing an odd problem with locks in the oob/tcp when using orte_output. I haven't had time to track it down yet.

= 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.

start sending fragment by copy in/out before ACK is received as we don't
know pointer to receive request yet.
Pipeline protocol sometimes doesn't send ACK though, so this case is still
broken.

* Remove the opal_only option. This was suffering from bit rot, and no one uses it. It can be added back fairly easily if wanted.
* Cleanup metadata interactions at the local level.
* Touch up some of the INC funcitonality (fix typos and a minor ordering issue)

If there is no IP Address, have rdmacm log the correct error and let
another cpc have a go at it. This is being done by splitting off the
IP address checking logic for the modex message creation, and having
it log the correct error in the error case.
This commit was SVN r18392.
For iWARP, the TCP connection is tied to the QP once the QP is in RTS.
And destroying the QP is thus tied to connection teardown for iWARP.
This is a key distinction from IB, I think. Anyway, to destroy the
connection in iWARP you must move the QP out of RTS, either into CLOSING
for a nice graceful close, or to ERROR if you want to be rude. In both
cases, all pending non-completed SQ and RQ WRs must be flushed.
This patch ignores all flush errors reaped by the cq and removes an
earlier attempt to work around this in the rdmacm cpc.

Any components not in the trunk, but in one of the effected frameworks *must* be

Sorry for the early commit of this, but I wanted to get it in today (per RFC) and
didn't know if I would have a chance later today.

If there are multiple QP's, RDMACM will not send a message if the
qpnum != 0. In doing so, it will log an error unecessarily. This
removes that.
