d4afb16f5a opal: rework mpool and rcache frameworks
This commit rewrites both the mpool and rcache frameworks. Summary of
changes:

 - Before this change a significant portion of the rcache
   functionality lived in mpool components. This meant that it was
   impossible to add a new memory pool to use with rdma networks
   (ugni, openib, etc) without duplicating the functionality of an
   existing mpool component. All the registration functionality has
   been removed from the mpool and placed in the rcache framework.

 - All registration cache mpools components (udreg, grdma, gpusm,
   rgpusm) have been changed to rcache components. rcaches are
   allocated and released in the same way mpool components were.

 - It is now valid to pass NULL as the resources argument when
   creating an rcache. At this time the gpusm and rgpusm components
   support this. All other rcache components require non-NULL
   resources.

 - A new mpool component has been added: hugepage. This component
   supports huge page allocations on linux.

 - Memory pools are now allocated using "hints". Each mpool component
   is queried with the hints and returns a priority. The current hints
   supported are NULL (uses posix_memalign/malloc), page_size=x (huge
   page mpool), and mpool=x.

 - The sm mpool has been moved to common/sm. This reflects that the sm
   mpool is specialized and not meant for any general
   allocations. This mpool may be moved back into the mpool framework
   if there is any objection.

 - The opal_free_list_init arguments have been updated. The unused0
   argument is not used to pass in the registration cache module. The
   mpool registration flags are now rcache registration flags.

 - All components have been updated to make use of the new framework
   interfaces.

As this commit makes significant changes to both the mpool and rcache
frameworks both versions have been bumped to 3.0.0.

b68d66bb9b MCA: Add the project/project version to the MCA base component
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.

All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.

5f1254d710 Update code base to use the new opal_free_list_t
Use of the old ompi_free_list_t and ompi_free_list_item_t is
deprecated. These classes will be removed in a future commit.

This commit updates the entire code base to use opal_free_list_t and
opal_free_list_item_t.

Notes:

OMPI_FREE_LIST_*_MT -> opal_free_list_* (uses opal_using_threads ())

WHAT:    Open our low-level communication infrastructure by moving all necessary components (btl/rcache/allocator/mpool) down in OPAL

All the components required for inter-process communications are currently deeply integrated in the OMPI layer. Several groups/institutions have express interest in having a more generic communication infrastructure, without all the OMPI layer dependencies.  This communication layer should be made available at a different software level, available to all layers in the Open MPI software stack. As an example, our ORTE layer could replace the current OOB and instead use the BTL directly, gaining access to more reactive network interfaces than TCP.  Similarly, external software libraries could take advantage of our highly optimized AM (active message) communication layer for their own purpose.  UTK with support from Sandia, developped a version of Open MPI where the entire communication infrastucture has been moved down to OPAL (btl/rcache/allocator/mpool). Most of the moved components have been updated to match the new schema, with few exceptions (mainly BTLs where I have no way of compiling/testing them). Thus, the completion of this RFC is tied to being able to completing this move for all BTLs. For this we need help from the rest of the Open MPI community, especially those supporting some of the BTLs.  A non-exhaustive list of BTLs that qualify here is: mx, portals4, scif, udapl, ugni, usnic.

e12ca48cd9 A number of C/R enhancements per RFC below:
http://www.open-mpi.org/community/lists/devel/2010/07/8240.php

Documentation:
  http://osl.iu.edu/research/ft/

Major Changes: 
-------------- 
 * Added C/R-enabled Debugging support. 
   Enabled with the --enable-crdebug flag. See the following website for more information: 
   http://osl.iu.edu/research/ft/crdebug/ 
 * Added Stable Storage (SStore) framework for checkpoint storage 
   * 'central' component does a direct to central storage save 
   * 'stage' component stages checkpoints to central storage while the application continues execution. 
     * 'stage' supports offline compression of checkpoints before moving (sstore_stage_compress) 
     * 'stage' supports local caching of checkpoints to improve automatic recovery (sstore_stage_caching) 
 * Added Compression (compress) framework to support 
 * Add two new ErrMgr recovery policies 
   * {{{crmig}}} C/R Process Migration 
   * {{{autor}}} C/R Automatic Recovery 
 * Added the {{{ompi-migrate}}} command line tool to support the {{{crmig}}} ErrMgr component 
 * Added CR MPI Ext functions (enable them with {{{--enable-mpi-ext=cr}}} configure option) 
   * {{{OMPI_CR_Checkpoint}}} (Fixes trac:2342) 
   * {{{OMPI_CR_Restart}}} 
   * {{{OMPI_CR_Migrate}}} (may need some more work for mapping rules) 
   * {{{OMPI_CR_INC_register_callback}}} (Fixes trac:2192) 
   * {{{OMPI_CR_Quiesce_start}}} 
   * {{{OMPI_CR_Quiesce_checkpoint}}} 
   * {{{OMPI_CR_Quiesce_end}}} 
   * {{{OMPI_CR_self_register_checkpoint_callback}}} 
   * {{{OMPI_CR_self_register_restart_callback}}} 
   * {{{OMPI_CR_self_register_continue_callback}}} 
 * The ErrMgr predicted_fault() interface has been changed to take an opal_list_t of ErrMgr defined types. This will allow us to better support a wider range of fault prediction services in the future. 
 * Add a progress meter to: 
   * FileM rsh (filem_rsh_process_meter) 
   * SnapC full (snapc_full_progress_meter) 
   * SStore stage (sstore_stage_progress_meter) 
 * Added 2 new command line options to ompi-restart 
   * --showme : Display the full command line that would have been exec'ed. 
   * --mpirun_opts : Command line options to pass directly to mpirun. (Fixes trac:2413) 
 * Deprecated some MCA params: 
   * crs_base_snapshot_dir deprecated, use sstore_stage_local_snapshot_dir 
   * snapc_base_global_snapshot_dir deprecated, use sstore_base_global_snapshot_dir 
   * snapc_base_global_shared deprecated, use sstore_stage_global_is_shared 
   * snapc_base_store_in_place deprecated, replaced with different components of SStore 
   * snapc_base_global_snapshot_ref deprecated, use sstore_base_global_snapshot_ref 
   * snapc_base_establish_global_snapshot_dir deprecated, never well supported 
   * snapc_full_skip_filem deprecated, use sstore_stage_skip_filem 

Minor Changes: 
-------------- 
 * Fixes trac:1924 : {{{ompi-restart}}} now recognizes path prefixed checkpoint handles and does the right thing. 
 * Fixes trac:2097 : {{{ompi-info}}} should now report all available CRS components 
 * Fixes trac:2161 : Manual checkpoint movement. A user can 'mv' a checkpoint directory from the original location to another and still restart from it. 
 * Fixes trac:2208 : Honor various TMPDIR varaibles instead of forcing {{{/tmp}}} 
 * Move {{{ompi_cr_continue_like_restart}}} to {{{orte_cr_continue_like_restart}}} to be more flexible in where this should be set. 
 * opal_crs_base_metadata_write* functions have been moved to SStore to support a wider range of metadata handling functionality. 
 * Cleanup the CRS framework and components to work with the SStore framework. 
 * Cleanup the SnapC framework and components to work with the SStore framework (cleans up these code paths considerably). 
 * Add 'quiesce' hook to CRCP for a future enhancement. 
 * We now require a BLCR version that supports {{{cr_request_file()}}} or {{{cr_request_checkpoint()}}} in order to make the code more maintainable. Note that {{{cr_request_file}}} has been deprecated since 0.7.0, so we prefer to use {{{cr_request_checkpoint()}}}. 
 * Add optional application level INC callbacks (registered through the CR MPI Ext interface). 
 * Increase the {{{opal_cr_thread_sleep_wait}}} parameter to 1000 microseconds to make the C/R thread less aggressive. 
 * {{{opal-restart}}} now looks for cache directories before falling back on stable storage when asked. 
 * {{{opal-restart}}} also support local decompression before restarting 
 * {{{orte-checkpoint}}} now uses the SStore framework to work with the metadata 
 * {{{orte-restart}}} now uses the SStore framework to work with the metadata 
 * Remove the {{{orte-restart}}} preload option. This was removed since the user only needs to select the 'stage' component in order to support this functionality. 
 * Since the '-am' parameter is saved in the metadata, {{{ompi-restart}}} no longer hard codes {{{-am ft-enable-cr}}}. 
 * Fix {{{hnp}}} ErrMgr so that if a previous component in the stack has 'fixed' the problem, then it should be skipped. 
 * Make sure to decrement the number of 'num_local_procs' in the orted when one goes away. 
 * odls now checks the SStore framework to see if it needs to load any checkpoint files before launching (to support 'stage'). This separates the SStore logic from the --preload-[binary|files] options. 
 * Add unique IDs to the named pipes established between the orted and the app in SnapC. This is to better support migration and automatic recovery activities. 
 * Improve the checks for 'already checkpointing' error path. 
 * A a recovery output timer, to show how long it takes to restart a job 
 * Do a better job of cleaning up the old session directory on restart. 
 * Add a local module to the autor and crmig ErrMgr components. These small modules prevent the 'orted' component from attempting a local recovery (Which does not work for MPI apps at the moment) 
 * Add a fix for bounding the checkpointable region between MPI_Init and MPI_Finalize.

e9b5162d79 Fix the configure logic for --with-ft so that it properly takes a comma separated list.
Many of the OPAL_ENABLE_FT should be OPAL_ENABLE_FT_CR, so fix those.

The OPAL Layer INC should call opal_output on restart so that it can refresh the string it prints to reflect the current pid/hostname which may have changed.

6c5532072a - Split the datatype engine into two parts: an MPI specific part in
OMPI
   and a language agnostic part in OPAL. The convertor is completely
   moved into OPAL.  This offers several benefits as described in RFC
   http://www.open-mpi.org/community/lists/devel/2009/07/6387.php
   namely:
    - Fewer basic types (int* and float* types, boolean and wchar
    - Fixing naming scheme to ompi-nomenclature.
    - Usability outside of the ompi-layer.
 - Due to the fixed nature of simple opal types, their information is
   completely
   known at compile time and therefore constified
 - With fewer datatypes (22), the actual sizes of bit-field types may be
   reduced
   from 64 to 32 bits, allowing reorganizing the opal_datatype
   structure, eliminating holes and keeping data required in convertor
   (upon send/recv) in one cacheline...
   This has implications to the convertor-datastructure and other parts
   of the code.
 - Several performance tests have been run, the netpipe latency does not
   change with
   this patch on Linux/x86-64 on the smoky cluster.
 - Extensive tests have been done to verify correctness (no new
   regressions) using:
   1. mpi_test_suite on linux/x86-64 using clean ompi-trunk and
    ompi-ddt:
    a. running both trunk and ompi-ddt resulted in no differences
       (except for MPI_SHORT_INT and MPI_TYPE_MIX_LB_UB do now run
       correctly).
    b. with --enable-memchecker and running under valgrind (one buglet
       when run with static found in test-suite, commited)
   2. ibm testsuite on linux/x86-64 using clean ompi-trunk and ompi-ddt:
      all passed (except for the dynamic/ tests failed!! as trunk/MTT)
   3. compilation and usage of HDF5 tests on Jaguar using PGI and
      PathScale compilers.
   4. compilation and usage on Scicortex.
 - Please note, that for the heterogeneous case, (-m32 compiled
   binaries/ompi), neither
   ompi-trunk, nor ompi-ddt branch would successfully launch.

9613b3176c Effectively revert the orte_output system and return to direct use of opal_output at all levels. Retain the orte_show_help subsystem to allow aggregation of show_help messages at the HNP.
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.

e7ecd56bd2 This commit represents a bunch of work on a Mercurial side branch. As
such, the commit message back to the master SVN repository is fairly
long.

= 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.

9971bc9d95 Merge in the mca_base_select changes per RFC:
http://www.open-mpi.org/community/lists/devel/2008/04/3779.php

{{{
svn merge -r 18276:18380 https://svn.open-mpi.org/svn/ompi/tmp-public/jjh-mca-play .
}}}

Any components not in the trunk, but in one of the effected frameworks *must* be
updated. Contact the list, look at the RFC, or look at the diff for how to do this.

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.

This commit was SVN r18381.
