a04c8eb39a - Bring over the visibility feature, for a finer symbol export control
via the visibility feature that is provided by some compilers.

  Per default this feature is disabled, to enable it you need to
  configure with --enable-visibility and obviously you need a compiler
  with visibility support. Please refer to the wiki for more information.

8029893489 In multithreaded application sending of initial portion of a request may overlap
with RDMAing the rest of it. Also more than one RDMA writes can be performed
simultaneously by different threads. To make this code thread safe this patch
clones original request convertor for each RDMA fragment.

8c2385416f Per a developer request -
Make sure that the wrapper selection is compiled out if not enabling FT. Before the 
logic would skip over it since the conditional if statements would not be satisfied, 
now there are no additional if statements when compiled out.

With this modification the selection logic looks nearly identical to pre-r14051
with the exception of the non-FT related improvements.

18b2dca51c Bring in the code for routing xcast stage gate messages via the local orteds. This code is inactive unless you specifically request it via an mca param oob_xcast_mode (can be set to "linear" or "direct"). Direct mode is the old standard method where we send messages directly to each MPI process. Linear mode sends the xcast message via the orteds, with the HNP sending the message to each orted directly.
There is a binomial algorithm in the code (i.e., the HNP would send to a subset of the orteds, which then relay it on according to the typical log-2 algo), but that has a bug in it so the code won't let you select it even if you tried (and the mca param doesn't show, so you'd *really* have to try).

This also involved a slight change to the oob.xcast API, so propagated that as required.

Note: this has *only* been tested on rsh, SLURM, and Bproc environments (now that it has been transferred to the OMPI trunk, I'll need to re-test it [only done rsh so far]). It should work fine on any environment that uses the ORTE daemons - anywhere else, you are on your own... :-)

Also, correct a mistake where the orte_debug_flag was declared an int, but the mca param was set as a bool. Move the storage for that flag to the orte/runtime/params.c and orte/runtime/params.h files appropriately.

51fc2474f1 Don't keep the data attached to a fragment segmented when we have
to move it into the unexpected queue. Instead pack the data in
only one buffer. Now the code look more optimized and clear, but
I have a doubt about who's using this functionality. I think that
all BTLs always return only one memory segment attached to the
matching fragment (i.e. there is no unexpected iov type receive).

8f119d9063 Closes trac:977
Fix for memory corruption in the restarted process stack. This stemed from 
the brute force method we were previously using. This commit fixes this by
using a lighter weight solution focused in the r2 BML instead of above the PML.
This is a more efficient and flexible solution, and it solves the original
problem.

In the process I pulled out the ft_event function in the tcp BTL and r2 BML
into a set of *_ft.[c|h] files just to keep any updates to these code paths
as isolated as possible to make merging easier on everyone.

51f286d737 Just like r14289 on the ORTE trunk:
Per discussions with Brian and Ralph, make a slight correction in
where components are installed. Use $pkglibdir, not $libdir/openmpi,
so that when compiled in the orte trunk, components are installed to
the right directory (because the component search patch is checking
$pkglibdir).

d7e428909e two fixes, one mine, the other gleb's, I'm committing for gleb due to
time difference...  

1) The PML makes an assumption on local/remote completion semantics of the BTL
which Self BTL does not obey, nor should it, so we fix the PML
2) The Get protocol must handle the case when sender and reciever do not agree
on wheter the data is contiguous

- Let ob1 have its very own ft_event function (which I'll fill in shortly)

- PML base - destruct the array upon finalize. Shrink the include search so it stops after finding a match

1cb26e3b9c Finally the convertor export a convenience function to allow a consistent
computation of the current location on the pack/unpack process. This can
be used both for retrieving the pointer to the first byte (in the special
case of the cached RDMA protocol) and for getting the current
position (for the pipelined protocol).

I modified all BTLs, but most of them are still untested.

52ca6cf86c The mpi_leave_pinned and mpi_leave_pinned_pipeline MCA parameters were
needlessly registered in multiple different places, and none of them
had a good help string.  There was also an inconsistent check for
setting both mpi_leave_pinned and mpi_leave_pinned_pipeline (i.e., it
was only in ob1).  This commit moves the registration of these params
to one central place (ompi/runtime/ompi_mpi_params.c, with all other
mpi_* MCA params) and uses globals to propagate the values as
relevant.  The error check was also moved to the central location to
ensure that we can consistency everywhere.

Move the req_mtl structure back to the end of each of the structures in

for each MTL, which is larger than the req_mtl itself. The cast will cause
the *_request to overwrite parts of the heavy requests if the req_mtl
isn't the *LAST* thing on each structure (hence the comment). This was

cf196ce420 Instead of an unknown proc list that requires ownership transfer of data (which, in turn, requires a complex series of locks to be held during the transfer), use a modex backing store with backpointers from the proc to the backing store. The proc structures no longer own the modex data, which greatly simplifies locking when an unknown proc suddenly becomes known.

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).

98884e45e4 Clean up the way procs are added to the global process list after MPI_INIT:
* Do not add new procs to the global list during modex callback or
    when sharing orte names during accept/connect.  For modex, we
    cache the modex info for later, in case that proc ever does get
    added to the global proc list.  For accept/connect orte name
    exchange between the roots, we only need the orte name, so no
    need to add a proc structure anyway.  The procs will be added
    to the global process list during the proc exchange later in 
    the wireup process
  * Rename proc_get_namebuf and proc_get_proclist to proc_pack
    and proc_unpack and extend them to include all information
    needed to build that proc struct on a remote node (which
    includes ORTE name, architecture, and hostname).  Change
    unpack to call pml_add_procs for the entire list of new
    procs at once, rather than one at a time.
  * Remove ompi_proc_find_and_add from the public proc
    interface and make it a private function.  This function
    would add a half-created proc to the global proc list, so
    making it harder to call is a good thing.

This means that there's only two ways to add new procs into the global proc list at this time: During MPI_INIT via the call to ompi_proc_init, where my job is added to the list and via ompi_proc_unpack using a buffer from a packed proc list sent to us by someone else.  Currently, this is enough to implement MPI semantics.  We can extend the interface more if we like, but that may require HNP communication to get the remote proc information and I wanted to avoid that if at all possible.

30ca7457b4 Some BTLs (e.g TCP) can report put/get completion before data actually
hits the buffer on the other side. For this kind of BTLs we need to send
FIN through the same BTL, PUT was performed with so network will handle
ordering for us. If we will use another BTL, receiver can get FIN before
data will hit the buffer and complete request prematurely. We mark such
problematic BTLs with MCA_BTL_FLAGS_FAKE_RDMA flag (this kind of RDMA
is really fake, because the real one guaranties that sender will see the
completion only after receiver's NIC confirmed that all the data was
received).

protocol when multiple NICS are available between 2 peers. The fix force
the FIN message to take exactly the same path as the fragment it describe
(i.e. same path means same BTL). Otherwise, the FIN can be received by
the peer before the RDMA complete and the request will get freed
too early.

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).

a4bdcb4faa Fix a segfault that turned up in more MPI_THREAD_MULTIPLE testing.
Same sort of problem and fix as described in r12323 - mca_pml_ob1_recv_frag_progress() was segfaulting due to a NULL req_proc pointer.  The path leading to this was through the mca_pml_ob1_check_cantmatch_for_match() function, where we can match a frag using the same macros as mca_pml_ob1_frag_match() and never initialize the req_proc pointer.

This commit essentially caches the invoking comm/win/file on the
ompi_request_t. This, paired with the req_type field, allows us to
retrieve the invoking MPI object and invoke the proper errhandler.

The patch is missing most updates for the MPI-2 one-sided stuff (i.e.,
the patch mainly fixes comms and files); I didn't really understand
that code and didn't want to hazard trying to figure it out when Brian
can probably do it much more quickly.

So #250 will still stay open, pending MPI-2 one-sided updates for this
stuff.

126a68dc9a Big datatype commit. Remove all unused features of the datatype engine. As the memory
allocation logic is completely done outside the data-type engine (in the PML) there is
no need for any special case inside the data-type engine. There is less arguments for
the ompi_convertor_pack and ompi_convertor_unpack as well (the last field free_after is
not required anymore as there is no memory allocated in the engine itself). This change
affect all components using datatypes. I test most of them, but it might happens that I
miss some ... If it's the case please let me know (don't shoot the pianist!!).

A segfault would occur in mca_pml_ob1_recv_request_progress() when trying to prepare the convertor for unpacking, because the request's req_proc field was NULL.

Turns out that we weren't setting the req_proc field in the MCA_PML_OB1_CHECK_SPECIFIC_AND_WILD_RECEIVES_FOR_MATCH macro.  Instead of just setting it there I removed the other place req_proc was being set correctly, and instead took care of all the cases at once in mca_pml_ob1_recv_frag_match().

90be664b9f Some process_pending() functions get bml_btl on which resource was freed as a
parameter. For optimisation purpose only this BTL is used to send packet
through instead of trying to send packets through all BTLs. But actually the 
code was wrong. It simply used provided bml_btl and it may represent different
endpoint from packet's destination. The fixed code checks if packet's
destination is reachable through the BTL, finds appropriate bml_btl and only
then tries to send it through correct bml_btl.

f3f39e003e - Increment the pipeline depth before we trigger the send function. As
mentioned in the comment the completion/callback of the triggered 
  send operation can happen before the call returns. If this happens and
  if the pipeline depth is 0 before we triggered the send operation and 
  this is the last send operation of the request then the completion detection
  code will decrement the pipeline depth and check it for equality to 0.
  Because (0-1) != 0 the pml completion function for this request will 
  *not* be called.

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.

dfa1221c3b * AC_CONFIG_LINKS has a minor problem in that it always uses ln -s, rather
than $(LN_S).  This causes problems with with Windows and probably
  elsewhere (re: #200).  So use a slightly different trick to get the
  right header selected for the MEMCPY and TIMER components.

* Using the same trick used to solve the AC_CONFIG_LINKS problem, 
  stop using a separate header file for direct calling in the
  PML and MTL.  This lets me remove some icky code in ompi_mca.m4
  that was more fragile than I really liked.

9f927dc7c1 Minor cleanups. On the OB1 PML the endpoint is not used => remove it from the build.
There was some old code regarding the convertor which does not have to be there
(the problem was corrected a while ago). In the PML we already know how the progress
function is defined, so call the BML progress instead, which will save one function
call. 

The macro MCA_PML_OB1_COMPUTE_SEGMENT_LENGTH is already defined in the pml_ob1.h
so it should not be in the endpoint.h.
Remove a double definition of the mca_pml_ob1_progress function in the pml_ob1.h.

476c9e64df Don't keep multiples copies of the datatype and count. The only one we really need
is the one provided by the user. For the buffered send the real datatype used
for the communication is always MPI_BYTE and the count can be retrieved from
the req_bytes_packed field. This will decrease the size of the request by
one pointer and one size_t (8 bytes or 16 bytes depending on the architecture).

e658557d52 Move the convertor creation out of th critical path. If we expect a
message from a known peer (not MPI_ANY_SOURCE) then we can attach the
remote proc and initialize the convertor as soon as we know the data-type,
and the count (so basically in the _INIT macro). If it's not the case, then
create them in the _MATCHED macro (as in the original version). Of course,
beforeinitializing the convertor we check that there will be some data
in the message.

This commit, plus the convertor improvements from few days ago, lower the
latency for my test case environment (mvapi) by 0.1 microseconds. The convertor
now is as slim as it can be, I don't think there is anything else to

58cd591d3b PERUSE support for OB1. There we go, now the trunk has a partial peruse implementation.
We support all the events in the PERUSE specifications, but right now only one event
of each type can be attached to a communicator. This will be worked out in the future.
The events were places in such a way, that we will be able to measure the overhead
for our threading implementation (the cost of the synchronization objects).

5271948ec0 --- opal object changes
add object size to opal class
no longer need the size when allocating a new object as this is stored in
the class structure

--- dr changes 
Previous rev. maintained state on the communicator used for acking duplicate
fragments, but the communicator may be destroyed prior to successfull
delivery of an ack to the peer. We must therefore maintain this state
globally on a per peer, not a per peer, per communicator basis. 
This requires that we use a global rank on the wire and translate this as
appropriate to a local rank within the communicator.

dabe47ca3d A function declared as static inline and who's not used directly, but
only as a pointer reference completely confuse some compilers (gcc 4.1
included). Removing the inline (it was there before when the function
was used in the same file) seems to solve the problem. However, the most
strange thing is that the bug only appear when we compile directly in
the trunk directory. It just don't happens when we're using the VPATH
build.
