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.
This commit was SVN r32317.
Let's not make the move to OPAL any harder than it has to be; this
commit can wait until after the BTL move.

Previously, we were only checking connectivity upon first ''send'' to
a peer. But this ignores the case where the first communication to a
peer is actually an ACK -- i.e., we successfully received something
from the peer and we need to send an ACK back. So we need to verify
that the ACK will actually get there.
Specifically, certain asymmetric routing cases can lead to a hang if
we don't check the connectivity in both directions. E.g., if the
sender is able to get traffic to the receiver, but the receiver is
unable to get traffic back to the sender because it made a different
routing decision than the sender.
In this case, the connectivity checker from the sender could succeed
(because the connectivity checker will ACK along the same path in
which the ping was received), but sending a BTL ACK could fail
(because the BTL ACK will be sent back along the path chosen by the
graph algorithm, which, in an erroneous asymmetric routing scenario,
may be different/wrong).
Hence, we want to trigger the connectivity checker at the first
communication from A->B, which may either be a BTL send or an ACK.

- After fixing the hang, the test continued to fail because
ompi_datatype_is_contiguous_memory_layout() reports that MPI_EMPTY (the
origin datatype) is noncontiguous and Portals4/OSC does not support
noncontiguous datatypes at this time. However, in this case the origin
count is zero so contiguous/noncontiguous is irrelevant. Now we skip

Older gfortran compilers (e.g., the gfortran that ships in RHEL5) do
not support ISO_C_BINDING, and therefore do not support the
TYPE(C_PTR) type. As such, they cannot support the overloaded
interfaces for MPI_WIN_ALLOCATE_SHARED and MPI_SHARED_QUERY that are
mandated in MPI-3.
So we separate those interfaces out into a separate .F90 file that is
#include'd in the tkr mpi.F90 file. In this separate .F90 file, we
use an #if to determine whether the compiler supports ISO_C_BINDING or
not.
Also re-jiggered the order of testing in ompi_setup_mpi_fortran.m4: we
now need to test whether the compiler supports ISO_C_BINDING even when
we're only building the mpi module (not strictly when we're building
the mpi_f08 module).
Finally, tweaked the use-mpi-tkr/Makefile.am to:
* Add some proper dependencies for mpi.F90
* Allow the general AM compilation to be used instead of supplying a
specific rule for compiling mpi.F90

We have been getting several requests for new collectives that need to be inserted in various places of the MPI layer, all in support of either checkpoint/restart or various research efforts. Until now, this would require that the collective id's be generated at launch. which required modification
s to ORTE and other places. We chose not to make collectives reusable as the race conditions associated with resetting collective counters are daunti
ng.
This commit extends the collective system to allow self-generation of collective id's that the daemons need to support, thereby allowing developers to request any number of collectives for their work. There is one restriction: RTE collectives must occur at the process level - i.e., we don't curren
tly have a way of tagging the collective to a specific thread. From the comment in the code:
* In order to allow scalable
* generation of collective id's, they are formed as:
*
* top 32-bits are the jobid of the procs involved in
* the collective. For collectives across multiple jobs
* (e.g., in a connect_accept), the daemon jobid will
* be used as the id will be issued by mpirun. This
* won't cause problems because daemons don't use the
* collective_id
*
* bottom 32-bits are a rolling counter that recycles
* when the max is hit. The daemon will cleanup each
* collective upon completion, so this means a job can
* never have more than 2**32 collectives going on at
* a time. If someone needs more than that - they've got
* a problem.
*
* Note that this means (for now) that RTE-level collectives
* cannot be done by individual threads - they must be
* done at the overall process level. This is required as
* there is no guaranteed ordering for the collective id's,
* and all the participants must agree on the id of the
* collective they are executing. So if thread A on one
* process asks for a collective id before thread B does,
* but B asks before A on another process, the collectives will
* be mixed and not result in the expected behavior. We may
* find a way to relax this requirement in the future by
* adding a thread context id to the jobid field (maybe taking the
* lower 16-bits of that field).
This commit includes a test program (orte/test/mpi/coll_test.c) that cycles 100 times across barrier and modex collectives.

mca_btl_base_segment_t and replace them with des_local and des_remote
This change also updates the BTL version to 3.0.0. This commit does
not represent the final version of BTL 3.0.0. More changes are coming.
In making this change I updated all of the BTLs as well as BTL user's
to use the new structure members. Please evaluate your component to
ensure the changes are correct.
RFC text:
This is the first of several BTL interface changes I am proposing for
the 1.9/2.0 release series.
What: Change naming of btl descriptor members. I propose we change
des_src and des_dst (and their associated counts) to be des_local and
des_remote. For receive callbacks the des_local member will be used to
communicate the segment information to the callback. The proposed change
will include updating all of the doxygen in btl.h as well as updating
all BTLs and BTL users to use the new naming scheme.
Why: My btl usage makes use of both put and get operations on the same
descriptor. With the current naming scheme I need to ensure that there
is consistency beteen the segments described in des_src and des_dst
depending on whether a put or get operation is executed. Additionally,
the current naming prevents BTLs that do not require prepare/RMA matched
operations (do not set MCA_BTL_FLAGS_RDMA_MATCHED) from executing
multiple simultaneous put AND get operations. At the moment the
descriptor can only be used with one or the other. The naming change
makes it easier for BTL users to setup/modify descriptors for RMA
operations as the local segment and remote segment are always in the
same member field. The only issue I forsee with this change is that it
will require a little more work to move BTL fixes to the 1.8 release
series.

I recently found a case where ompi_mpi_abort() segv's:
{{{
$ mpirun --mca btl non_existent_btl_name ...
}}}
In this case, the BML init fails because we have no paths to any
peers. It calls ompi_mpi_abort(), but this is before ompi_comm_self
has been setup. ompi_mpi_abort() assumes that if the comm parameter
is != NULL, it can be used. But since we aborted so early in
MPI_INIT, that's a false assumption.
(note that this isn't happening on v1.8 because the check for
INIT/FINALIZE in ompi_mpi_abort() is a little different. Hence: this
is a trunk issue -- at least for now)
When fixing this problem, I noticed a few other problems in ompi_mpi_abort():
* the group access was incorrect (it didn't use accessor functions)
* it wasn't clear that ORTE's ompi_rte_abort_peers() returns
NOT_IMPLEMENTED and falls through down to ompi_rte_abort()
* the check for my proc in the communicator was a little more
complicated than necessary
* the logic for checking for aborts early in MPI_INIT wasn't right
* some comments were stale
* the hostname output in error messages would be NULL if MPI_FINALIZE
had been invoked
* it was possible to abort, but still exit with a 0 status
This commit fixes all of the above problems, and makes the logic a
little more straightforward. Thanks to Ralph Castain and George

RHEL 7 has shipped with kernel support for the RDMA_TRANSPORT_USNIC
enum, but ''not'' the RDMA_TRANSPORT_USNIC_UDP enum. This means that
when you install usNIC drivers from cisco.com, the kernel will report
IBV_TRANSPORT_USNIC, even though the transport is actually using UDP.
Therefore, we have to modify the logic in common/verbs to do the
additional magic probe if the device reports either an
IBV_TRANSPORT_IWARP or IBV_TRANSPORT_USNIC (because both of those might
be lies -- do the probe to figure out the real transport).
The code changed by this patch is fairly trivial; it simply moves the
logic of the magic probe to its own short function, and then calls that
short function in both the IBV_TRANSPORT_(IWARP|USNIC) cases. It looks
longer because several lengthy comments were also updated.

There is more comprehensive work regarding MPI_SIZEOF coming, but the
Fortran working group in the MPI Forum is debating this internally,
and I'm still doing more testing to get a final solution. So for the
moment, just remove real*16 and complex*32 support so that it compiles
porperly with older compilers (that do not support real*16 and
complex*32).

Move them all to fortran/use-mpi-f08, since that's the only directory
that uses them (the use-mpi-f08-desc directory has been disabled).

This is part one of several Fortran improvements and fixes. This
first part removes the now-defunct scripts that are used to generate
the .f90 files in the use-mpi-tkr implementation, and just commits the
output from those scripts. This makes long-term maintenance of the
use-mpi-tkr implementation simpler.

Move away from verbs-specific terms "device" and "port" in the usnic
BTL help messages. Replace them with "usNIC interface" (since usNIC
has no concept of a port).

The post and start window calls are supposed to be matching. The code
did not check to see that an incoming post matched with the start call.
This commit fixes the bug by placing the post on a pending list that
will be checked by the next call to start.

The replace callback did not increment the incoming frag counter. This
leads to a hang during synchronization. This commit adds the increment
and also puts the request on the garbage collection list to fix a leak.
This fixes a hang found when running the mpich test suite.

The wrong type was used when calculating the amount of space needed
for an accumulate fragment. Fixed the calculation and took the
opportunity to eliminate the get_acc header as it is identical to the
acc header.
This fixes trac:4719 and #4718

This changeset :
- always call the low/level implementation for :
* MPI_Alltoallv
* MPI_Neighbor_alltoallv
* MPI_Alltoallw
* MPI_Neighbor_alltoallv
- fix mca_coll_tuned_alltoallv_intra_basic_inplace
so zero size types are correctly handled

This addresses an issue found with the MPICH pscw_ordering test. Eager sends
were not yet active (which is ok for the standard path) but not ok for the
self optimization. Fixed by waiting for all post messages before checking
the sync state.

It is valid to lock/unlock MPI_PROC_NULL. It probably isn't work tracking
whether MPI_PROC_NULL is locked for MPI_PROC_NULL RMA operations so this
is probably the permanent solution.

Only one field is valid for RMA requests: MPI_ERROR. This field is set
to the correct value in ompi_request_empty so there is no reason to
allocate and keep track of osc/sm requests because they are always
complete on return. Since we are no longer using the osc/sm request
structure or free list they are now removed.

Correctly handle the corner case in MPI_Alltoallv when
some tasks have no data to transfer and some other tasks
do have data to transfer.
This test case is covered in ibm/collective/alltoallv_somezeros

is really special as the weights can be one of the following three
values (NULL, EMPTY or some legal value). As such, we need a complex
if to correctly convert the Fortran value to the corresponding C
value. Thus, always defining the c_ array is the simplest and most
straighforward approach.

This would be a really, really weird case if it ever happens (i.e.,
you have usnics but the agent process failed somewhere in MPI_INIT
such that the agent never appears), but having an infinite loop
doesn't seem like a good idea.

This conservative fixes tries to fetch info from both
opal_dstore_nonpeer and opal_dstore_peer.
This is required is task A spawns tasks B and C.
B was previously unable to find info from C, this caused locality
info not being set and a hang in coll/ml init.

Revamp the ORTE global data structures to reduce memory footprint and add new features. Add ability to control/set cpu frequency, though this can only be done if the sys admin has setup the system to support it (or you run as root).
