At the developer meeting today, the question was raised as to whether
the SCTP BTL was maintained any more. I emailed Alan Wagner to see if
he had any interest/resources to continue to maintain the SCTP BTL.
He indicated that he unfortunately had any resources to maintain it;
it would be fine to remove the SCTP BTL from the trunk.
So long, SCTP BTL... fare thee well...
This commit was SVN r32075.
1: find/create procs, and create associated endpoint for each
2: resolve peer addresses
The 2nd part is done as a separate loop so that the address lookups
can be parallelized.
The overall result is to split usnic_add_procs() into two smaller,
simpler parts.

When ibv_create_ah() fails due to an address resolution failure, it
really only means that we can't reach that one peer -- so we should
just ignore that one peer. If ibv_create_ah() fails for some other
reason, then give up on the entire usnic_X device.
Change the show_help() message that is displayed when ibv_create_ah()
fails due to address resolution failure; indicate that it's likely a
routing problem. Also opal_output_verbose() the same info, since
show_help() is de-duplicated (and this particular show_help() message
can be squelched).
Fixes Cisco bugs CSCup35851 and CSCup35872.

Move away from verbs-specific terms "device" and "port" in the usnic

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.

This commit was SVN r32016.
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

* MPI_Alltoallw
* MPI_Neighbor_alltoallv
- fix mca_coll_tuned_alltoallv_intra_basic_inplace

in self optimization
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.

This commit was SVN r32010.
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.
Closes trac:4723

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
from the ompi-tests repo.

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.
(does not need to go to v1.8 because v1.8 still uses RML for
communication for the connectivity checker)
This commit was SVN r31932.
if eager rdma is used, endpoint reference_count is greater than one.
this commit is a temporary fix that OBJ_RELEASE the endpoint as much as needed.
thought this is likely correct, it can be suboptimal and hence needs to be reviewed

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).
This commit was SVN r31916.
We were still leaking 1) file descriptors for data files, and 2) some
control files. I fixed both of these leaks and everything is looking
good. This should fix the bug where we are running out of file
descriptors when running the loop_spawn test. I also too the
opportunity to refactor the code a bit to make the mapping/unmapping
simpler. This should help avoid these sorts of issues in the future.
Depends on #4678

if in_ptr is NULL, the MAP_FIXED flag cannot be passed to mmap

test suite on trunk.
cmr=v1.8.2:reviewer=hjelmn
This commit was SVN r31890.
Per Ralph :
"I noticed that we are incrementing and decrementing the opal_progress_event state.
However, this no longer has any impact whatsoever on the RML as that is running in
the independent ORTE event thread. So all this actually does is impact the MPI layer
by adding an unnecessary overhead."
Thanks Ralph for pointing this :-)

Now that the infrastructure is calling BTL del_procs() before the BTL
finalize(), the usnic BTL had to re-order some of its teardown
sequence to avoid assert() failing.
This is part of a larger conversation involving #4669. Since
MPI_FINALIZE and MPI_COMM_DISCONNECT currently use an
oob/grpcomm-based barrier, the usnic BTL can ''absolutely know'' that
these endpoints and procs will no longer be used. If the ORTE DPM
goes back to a PML-based barrier, the usnic BTL will need to grow more
complex teardown semantics (a la TCP socket FIN/ACK/FIN_WAIT states).

This commit was SVN r31871.
The following Trac tickets were found above:
Ticket 4669 --> https://svn.open-mpi.org/trac/ompi/ticket/4669
to be based on grpcomm (i.e., an out-of-band based barrier) rather
than the simplistic PML-based barrier that it currently uses.
This is pending a larger discussion with Nathan and George, but it
will allow the usnic BTL to stop assert()-failing in light of the
recent del_procs() change.
