Keeping the cache misses as low as possible is always a good approach.
The opal_list_t is widely used, it should be a highly optimized class.
The same functionality can be reached with one one sentinel instead
of 2 currently used.
I don't have anything against the STL version, but so far nothing can
compare with the Knuth algorithm. I replace the current implementation
with a modified version of the Knuth algorithm (the one described in
The Art of Computer Programming). As expected, the latency went down.

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.

I've introduced a race condition - seeing occasional LOCAL_LENGTH errors on the receive side. I think I'm mixing up eager/max somehow - will look at it more on monday.

convertor doesn't handle it properly
continue peeking until we don't get anything else..
close the endpoint before closing the library..
add a blocking send that uses mx_test ..

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).

bsend_request_init, but not both. Otherwise, you don't free
some buffer space and end up leaking buffers and ending in
badness
* since you only call alloc() or init(), but not both, need to
restore reference counting in init()
This commit was SVN r10674.
* 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 :-) )

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.

interconnects that provide matching logic in the library.
Currently includes support for MX and some support for
Portals
* Fix overuse of proc_pml pointer on the ompi_proc structuer,
splitting into proc_pml for pml data and proc_bml for
the BML endpoint data
* bug fixes in bsend init code, which wasn't being used by
the OB1 or DR PMLs...

This moves the logic to create the symbolic links for:
- mpirun
- mpiexec
- ompi-ps
- ompi-clean
and their respective man pages to the ompi level from
the orte layer.
This is a bit pedantic, but orte shouldn't be doing the
work of ompi since that is a bit of an abstraction break.
Note: need to autogen.sh to get this. Sorry :(

yes this means it WAS possible for two nodes to choice two different algorithms
(discovered by Doug Gregor and figured out by George)
Also changed some names like size to comsize so we know which sizes we are using where
This should be updated in al versions
