afbe3e99c6 * Wrap all the direct error-code checks of the form (OMPI_ERR_* == ret) with
(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
 SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
 back the native error code.

* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
  (OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
  decode 'ret' to get the native error code.

0feb158aaf - Since r22727 orte_app_idx_t was introduced, being a uint32_t (was
previously an orte_std_cntr_t, which is int32_t).
   Comparison with < 0 don't make any sense, here.

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.

95596d1814 - Move alignment and size output generated by configure-tests
into the OPAL namespace, eliminating cases like opal/util/arch.c
   testing for ompi_fortran_logical_t.
   As this is processor- and compiler-related information
   (e.g. does the compiler/architecture support REAL*16)
   this should have been on the OPAL layer.
 - Unifies f77 code using MPI_Flogical instead of opal_fortran_logical_t

 - Tested locally (Linux/x86-64) with mpich and intel testsuite
   but would like to get this week-ends MTT output


 - PLEASE NOTE: configure-internal macro-names and
   ompi_cv_ variables have not been changed, so that
   external platform (not in contrib/) files still work.

25249c9843 Roll back r20926, r20941, r20950: Iain's changes from last week.
This has turned into an MPI spec interpretation issue.  :-(

Open MPI has intrepreted the spec one way for the past several years;
these commits reflect a different interpretation that changes how we
treat the EXTRA_STATE parameter to the Fortran attribute copy and
delete callbacks.  This new way breaks our internal copy of the Intel
Fortran attribute tests.  So after talking with Terry/Sun, we're going
to back out these changes (both here and on the v1.3 branch) until we
get further clarification from the Forum.

0a24eadaad Fix Fortran bindings for MPI_KEYVAL_CREATE and MPI_COMM_CREATE_KEYVAL.
The EXTRA_STATE parameter is passed by reference, and thus should be
dereferenced before it is stored.  Similarly, the stored value should
be passed by reference to the copy and delete routines.

This fixes trac:1864.

ba5498cdc6 Repair the MPI-2 dynamic operations. This includes:
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.

98f70d6318 Convert the C++ Comm, Datatype and Winn keyval creation and intercept callbacks
to *not* use the STL as well as removing the STL use from the error handler
routines.  This was removing the STL from the C++ bindings (Solaris has 2
versions of the STL; if OMPI uses one and an MPI application wants to use
another, Bad Things happen).

The main idea is to wrap up the C++ callback function pointers and the user's
extra_state into our own struct that is passed as the extra_state to the C
keyval registration along with the intercept routines in intercepts.cc. When the
C++ intercepts are activated, they unwrap the user's callback and extra state
and call them.

84d1512fba Add the potential for doing some basic error checking on mutexes during
single threaded builds.  In its default configuration, all this does
is ensure that there's at least a good chance of threads building
based on non-threaded development (since the variable names will be
checked).  There is also code to make sure that a "mutex" is never
"double locked" when using the conditional macro mutex operations.
This is off by default because there are a number of places in both
ORTE and OMPI where this alarm spews mega bytes of errors on a
simple test.  So we have some work to do on our path towards
thread support.

Also removed the macro versions of the non-conditional thread locks,
as the only places they were used, the author of the code intended
to use the conditional thread locks.  So now you have upper-case
macros for conditional thread locks and lowercase functions for
non-conditional locks.  Simple, right? :).

260f1fd468 Fixes trac:817
The C++ bindings were not tracking keyvals properly -- they were
freeing some internal meta data when Free_keyval() was called, not
when the keyval was actually destroyed (keyvals are refcounted in the
C layer, just like all other MPI objects, because they can live for
long after their corresponding Free call is invoked).  This commit
fixes this problem and several other things:

 * Add infrastructure on the ompi_attribute_keyval_t for an "extra"
   destructor pointer that will be invoked during the "real"
   constructor (i.e., when OBJ_RELEASE puts the refcount to 0).  This
   allows calling back into the C++ layer to release meta data
   associated with the keyval.
 * Adjust all cases where keyvals are created to pass in relevant
   destructors (NULL or the C++ destructor).
 * Do essentially the same for MPI::Comm, MPI::Win, and MPI:Datatype:
   * Move several functions out of the .cc file into the _inln.h file
     since they no longer require locks
   * Make the 4 Create_keyval() functions call a common back-end
     keyval creation function that does the Right Thing depending on
     whether C or C++ function pointers were used for the keyval
     functions.  The back-end function does not call the corresponding
     C MPI_*_create_keyval function, but rather does the work itself
     so that it can associate a "destructor" callback for the C++
     bindings for when the keyval is actually destroyed.
   * Change a few type names to be more indicative of what they are
     (mostly dealing with keyvals [not "keys"]).
 * Add the 3 missing bindings for MPI::Comm::Create_keyval().
 * Remove MPI::Comm::comm_map (and associated types) because it's no
   longer necessary in the intercepts -- it was a by-product of being
   a portable C++ bindings layer.  Now we can just query the C layer
   directly to figure out what type a communicator is.  This solves
   some logistics / callback issues, too.
 * Rename several types, variables, and fix many comments in the
   back-end C attribute implementation to make the names really
   reflect what they are (keyvals vs. attributes).  The previous names
   heavily overloaded the name "key" and were ''extremely''
   confusing.

0a5d41857a Complete next round of message size reduction: "strip" the descriptive info from the returned values. I have now added a flag to the gpr address mode (ORTE_GPR_STRIPPED) that instructs the gpr to not include segment names or tokens in the returned gpr_value_t objects.
I found only two places that were looking at the tokens:

1. the odls - we used the tokens to separately process the globals container data from everything else. In this case, I left the subscription that returned the globals data alone, but "stripped" the subscription that returned the launch data for the procs. These subscriptions have nothing to do with the xcast message.

2. the pml_base_modex - the callback function was getting process names from the returned tokens. Actually, this function was doing a very bad thing - it was assuming that the first token returned was *always* the process name. This is currently true, but is one of those assumptions that someone could have easily changed - and suddenly found the system inexplicably failing. I modified the function to (a) get the name sent back to us, (b) "stripped" the value structures of tokens and segment strings, and (c) correctly obtained process names from the returned values. I also reindented the heck out of the code so it was legible (at least, to my old eyes).

a1153fdc8f Eliminate virtually all of the attribute_predefined data from the STG1 message. We now compute the total number of slots allocated to us and save that in the registry - the attributed_predefined then retrieves it via the STG1 message. The app_num is passed via the process_info structure, which gets the value from the ODLS in the environment.
Obviously, people like bproc will have to get the app_num via another avenue...but that's a problem for another day. Several options are easily available.

1359ba9b13 Rewriting much of the errorcode and errorclass code, since
- we have to be able to attach a string to an error class, not just to an
 error code
 - according to MPI-2 the attribute MPI_LASTUSEDCODE has to be updated
  everytime you add a new code or a new class. Thus, you have to have single
  list for both. 

Thus, we got rid of the error_class structure. In the error-code structure, we
can distinguish whether we are dealing with an error code or an error class by
looking at the err->code element of the structure. In case its value is
MPI_UNDEFINED, the according entry is a class, else it is an error code. All
predefined error codes have the code and the class field set to the same
value.

The test MPI_Add_error_class1 passes now.

6d6cebb4a7 Bring over the update to terminate orteds that are generated by a dynamic spawn such as comm_spawn. This introduces the concept of a job "family" - i.e., jobs that have a parent/child relationship. Comm_spawn'ed jobs have a parent (the one that spawned them). We track that relationship throughout the lineage - i.e., if a comm_spawned job in turn calls comm_spawn, then it has a parent (the one that spawned it) and a "root" job (the original job that started things).
Accordingly, there are new APIs to the name service to support the ability to get a job's parent, root, immediate children, and all its descendants. In addition, the terminate_job, terminate_orted, and signal_job APIs for the PLS have been modified to accept attributes that define the extent of their actions. For example, doing a "terminate_job" with an attribute of ORTE_NS_INCLUDE_DESCENDANTS will terminate the given jobid AND all jobs that descended from it.

I have tested this capability on a MacBook under rsh, Odin under SLURM, and LANL's Flash (bproc). It worked successfully on non-MPI jobs (both simple and including a spawn), and MPI jobs (again, both simple and with a spawn).

17c71f8d2a Fix ticket #545
Setup subscriptions to correctly return the MPI_APPNUM attribute.

Fix an unreported bug that was found. The universe size was incorrectly defined in the attributes code. As coded, it looked for size_t values and based its size computation on those numbers. Unfortunately, the node_slots value had been changed to an orte_std_cntr_t awhile back! So the universe size was never updated.

Update the hello_nodename test to check for MPI_APPNUM.

Add a definition to ns_types for ORTE_PROC_MY_NAME - just a shortcut for orte_process_info.my_name. Brought over from ORTE 2.0 as it will be used extensively there.

06563b5dec Last set of explicit conversions. We are now close to the zero warnings on
all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
  a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
  when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

5dfd54c778 With the branch to 1.2 made....
Clean up the remainder of the size_t references in the runtime itself. Convert to orte_std_cntr_t wherever it makes sense (only avoid those places where the actual memory size is referenced).

Remove the obsolete oob barrier function (we actually obsoleted it a long time ago - just never bothered to clean it up).

I have done my best to go through all the components and catch everything, even if I couldn't test compile them since I wasn't on that type of system. Still, I cannot guarantee that problems won't show up when you test this on specific systems. Usually, these will just show as "warning: comparison between signed and unsigned" notes which are easily fixed (just change a size_t to orte_std_cntr_t).

In some places, people didn't use size_t, but instead used some other variant (e.g., I found several places with uint32_t). I tried to catch all of them, but...

Once we get all the instances caught and fixed, this should once and for all resolve many of the heterogeneity problems.

429c25095e Fix for bug #176.
* Fix for two problems introduced by r10661:
   1. ensure to use the key ''after'' it is initialized (sigh).
   1. handle the case where we free the attrkey before it is fully
      initialized (i.e., some other error causes us to free it).  In
      this case, don't try to remove the key from the hash map,
      because it won't exist.
 * More accurate zeroing in the keyval constructor
   (ompi_attrkey_item_constructor)
 * Widen the scope of the alock such that the attrkey destructor does
   not need to acquire it.  Instead, assume that the caller already
   has it.
 * Add a comment about why the keyval may get destroyed as the result
   of deleting an attribute (so that I don't have to figure it out
   again the next time I read this code :-) )

fdba2c9df0 Per the analysis in bug #184, move some assignments around to effect
thread safety.  This is likely to be only the first of multiple steps
for complete thread safety in the MPI attribute code.  All tests
[continue to] pass the intel and ibm attribute tests.

Also renamed a variable from "attr" to "attrkey" to reflect that it's
a keyval, not an attribute.

f6bbe033f0 The output of the copy function is a logical, not an int. So we need
to use the appropriate macro for all the Fortran .TRUE. handling, or
things get misinterpeted and, with some compilers, it will look like
the attribute wasn't copied properly.

85bb1a9c90 Add one more argument to the copy functions for the MPI objects. As this argument
is the last one on the list and as on C the caller "make it right" this addition
will not affect the way we handle the user defined copy functions. Only the C
version of the function has this additional parameter. As it represent the pointer
to the newly created MPI object It hold the key to allow us to modify the new
object (communicator, window or type) depending on some key stored on the initial
communicator.

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)

b1d2424013 Merge in present work on the MPI-2 onesided chapter. The current code is not
complete, but stable enough that it will have no impact on general development,
so into the trunk it goes.  Changes in this commit include:

 - Remove the --with option for disabling MPI-2 onesided support.  It
   complicated code, and has no real reason for existing
 - add a framework osc (OneSided Communication) for encapsulating
   all the MPI-2 onesided functionality
 - Modify the MPI interface functions for the MPI-2 onesided chapter
   to properly call the underlying framework and do the required
   error checking
 - Created an osc component pt2pt, which is layered over the BML/BTL
   for communication (although it also uses the PML for long message
   transfers).  Currently, all support functions, all communication
   functions (Put, Get, Accumulate), and the Fence synchronization
   function are implemented.  The PWSC active synchronization
   functions and Lock/Unlock passive synchronization functions are
   still not implemented
