the memory descriptor is closing itself, so that it actually works properly ;). I think I
was just getting lucky and not sending enough short messages with the reference impl.

* It appears that Cray's SeaStar has some horrible performance for iovecs - IN_pLACE
was actually slower than copying into eager frags. Ugh. And we don't even pre-pin
eager frags yet!

pointer. Otherwise, we can end up segfaulting when the memory area is
used by the caller. Fixes a bug reported by Alex Spiegel.

but causes resource exhaustion on the Red Storm implementation. Sigh...

The following SVN revision numbers were found above:
r9005 --> open-mpi/ompi@20d06e889e
(1) As pointed out by Torsten after Jeff comment that there are 15 collectives yesterday.. nope.. I have 16 but
miss counted them in my ifdefs (I had two #11s). Replaces with enum...
(2) Added a readonly MCA param for how many backend algorithms are available per collective (used by benchmarker/STS)
This allowed me to remove the tuned query internal functions and replace them with ompi_coll_tuned_forced_max_algorithms[COLL].
(3) I was reading the user forced MCA params for the collectives on each comm create (module init) but I then put the
values into a global set of variables (like ompi_coll_tuned_reduce_forced_algorithm).
To fix this and make the code neater:
(a) The component looks up the MCA param indices on Open if dynamic_rules is set via the
ompi_coll_tuned_COLLECTIVE_intra_check_forced_init () call.
(b) Got rid of the ompi_coll_ompi_coll_tuned_COLLECTIVE_forced_algorithm/segmentsize/etc globals with a struct that
is now cached on the module data hung off the communicator. i.e. done right.
(c) On module init if dynamic rules enabled we call a general getvalues routine (in coll_tuned_forced.c) to get the
CURRENT values using the MCA param indices and then put them on the modules data segment.
A shorter version of getvalues exists for barrier which only needs the algorithm choice

- Some initial work on prepare_src
- Move some fragment initialization around
- Fix a union casting issue on picky compilers, identified by Don Kerr
- Other small cleanups/bugfixes
This commit was SVN r9662.
we send our local addr_t OOB. Remote side then matches endpoints and calls
dat_ep_connect(). Everything should be the same as before from here, except
that client/server roles are reversed.
- Properly set our buffer size when posting receives. When the frag used to
transfer address information is recycled by the free list, the wrong buffer
size was being used, which caused buffer overflow errors.
- Finally put the uDAPL error handling stuff in the mpool component.
- Remove a few more OPAL_OUTPUTs.
This commit was SVN r9569.
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).
This commit was SVN r9500.
Not much got tested that wasn't already - I've uncovered a connection
establishment deadlock and wanted to get these changes committed before I
attack it.
The big changes:
- Moved much of the connection code from btl_udapl_component.c to
btl_udapl_endpoint.c.
- Cleaned up initialization of various fragment members.
- MCA_BTL_UDAPL_ERROR macro, which is compiled in/out appropriately.

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.

* Add ability to start Put and Get requests immediately instead of queuing
until synchronizaion when using Fence. Not entirely sure this is
completely safe, so it must be explicitly enabled by the user, either with
an MCA parameter or info argument to Win_create.

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.

* Install peruse.h in $includedir, since applications need to be able
to include it as <peruse.h>
* Fix issue with onesided code always installing it's headers
