aa82acd34c continuing the incremental changes. fl_elem_class renamed fl_frag_class,
and ompi_free_list_init_new() and ompi_free_list_init_ex_new() were added.
Next step will be to start converting from ompi_free_list_init to()
ompi_free_list_init_new(), and then remove ompi_free_list_init(), and
rename ompi_free_list_init_new() back to ompi_free_list_init().  The merge
of the branch with the trunk was so substantial, it is far easeir to
re-implement the changes in the trunk, rather than trying to fix the bugs
the merge brought in ...

e724ca0a1f Remodel the ompi_free_list a little. The free_list_memory is in
fact a free_list_item so instead of having a struct, use typedef
to make them equivalent. Modify the parallel debuggers support
in order to allow them access to the internal types even when
we have an optimized build.

8ace07efed This commit brings in two major things:
1. Galen's fine-grain control of queue pair resources in the openib
   BTL.
1. Pasha's new implementation of asychronous HCA event handling.

Pasha's new implementation doesn't take much explanation, but the new
"multifrag" stuff does.  

Note that "svn merge" was not used to bring this new code from the
/tmp/ib_multifrag branch -- something Bad happened in the periodic
trunk pulls on that branch making an actual merge back to the trunk
effectively impossible (i.e., lots and lots of arbitrary conflicts and
artifical changes).  :-(

== Fine-grain control of queue pair resources ==

Galen's fine-grain control of queue pair resources to the OpenIB BTL
(thanks to Gleb for fixing broken code and providing additional
functionality, Pasha for finding broken code, and Jeff for doing all
the svn work and regression testing).

Prior to this commit, the OpenIB BTL created two queue pairs: one for
eager size fragments and one for max send size fragments.  When the
use of the shared receive queue (SRQ) was specified (via "-mca
btl_openib_use_srq 1"), these QPs would use a shared receive queue for
receive buffers instead of the default per-peer (PP) receive queues
and buffers.  One consequence of this design is that receive buffer
utilization (the size of the data received as a percentage of the
receive buffer used for the data) was quite poor for a number of
applications.

The new design allows multiple QPs to be specified at runtime.  Each
QP can be setup to use PP or SRQ receive buffers as well as giving
fine-grained control over receive buffer size, number of receive
buffers to post, when to replenish the receive queue (low water mark)
and for SRQ QPs, the number of outstanding sends can also be
specified.  The following is an example of the syntax to describe QPs
to the OpenIB BTL using the new MCA parameter btl_openib_receive_queues:

{{{
-mca btl_openib_receive_queues \
     "P,128,16,4;S,1024,256,128,32;S,4096,256,128,32;S,65536,256,128,32"
}}}

Each QP description is delimited by ";" (semicolon) with individual
fields of the QP description delimited by "," (comma).  The above
example therefore describes 4 QPs.

The first QP is:

    P,128,16,4

Meaning: per-peer receive buffer QPs are indicated by a starting field
of "P"; the first QP (shown above) is therefore a per-peer based QP.
The second field indicates the size of the receive buffer in bytes
(128 bytes).  The third field indicates the number of receive buffers
to allocate to the QP (16).  The fourth field indicates the low
watermark for receive buffers at which time the BTL will repost
receive buffers to the QP (4).

The second QP is:

    S,1024,256,128,32

Shared receive queue based QPs are indicated by a starting field of
"S"; the second QP (shown above) is therefore a shared receive queue
based QP.  The second, third and fourth fields are the same as in the
per-peer based QP.  The fifth field is the number of outstanding sends
that are allowed at a given time on the QP (32).  This provides a
"good enough" mechanism of flow control for some regular communication
patterns.

QPs MUST be specified in ascending receive buffer size order.  This
requirement may be removed prior to 1.3 release.

90fb58de4f When frags are allocated from mpool by free_list the frag structure is also
allocated from mpool memory (which is registered memory for RDMA transports)
This is not a problem for a small jobs, but for a big number of ranks an
amount of waisted memory is big.

33f300f636 I don't know what it was supposed to do but I'm quite sure it didn't do it correctly.
Just follow inc_num and you will understand. Now _resize will grow the list to match
the required number of elements as described in the comment in the .h file.

51b2a0fd3f A couple of changes to improve shared memory behavior when resources get
constrained:

  * Make sure we always have a number of eager fragments available
    that scales with the number of processes communicating with
    a given proc over shared memory
  * Use FREE_LIST_GET instead of FREE_LIST_WAIT to return an
    error to the PML when resource exhaustion occurs
  * Don't dereference the frag during alloc unless we're sure
    it's not NULL

9eb023a5c2 OK my last commit was ... kind of wrong. It only worked if the element_size
was smaller than the CACHE_LINE_SIZE. Here is the version that works.

In fact this works on 2 steps. First we set the element size to something
multiple of the desired alignment. Then when we allocate memory, we compute
the total size, and we will align each of the elements (we allocate
multiple of them every time) to the CACHE_LINE_SIZE.

c71f6c9765 All elements will be aligned to the CACHE_LINE_SIZE define (currently 128
bytes). The simplest way to make sure they are aligned is to update
the size of the basic element to a multiple of the desired alignment.
It will use a little bit more memory, but the improvements on the SM BTL
seems quite interesting.

b92e78761a I did it under pressure !!!
The free lst using atomic operations. I didn't want to completely
change the behavior, so we still use a mutex for the extreme cases (like
no more available items and we cannot allocate more). I test it for a
while on non multi-threading environment, but not enough on a multi-threaded
build.
