8852c00c36 Look like a big commit but in fact it address only one issue. The way we're working with
size and diplacement of data-type. After this patch all data can contain size_t bytes
and the displacements are defined as ptrdiff_t. All of the files I was able to compile
have been modified to match this requirement.

This commit was SVN r12146.

a8e9fa09da Fix some compiler warnings introduced in r11619. I checked with
George: ompi_ddt_type_size() returns a signed int only because of the
MPI spec; it will never return a negative value.  So casting the
return value out of it to a (uint32_t) is safe, and makes the
comparisons be between two unsigned values. 

This commit was SVN r11639.

The following SVN revision numbers were found above:

8667648a1b Simple fix (for ticket 363). We push segment size to type size. In other algorithms we switch of segementing altogether. But really the DDT can probably handle partial types so we could really keep the segsize constant (for all but reduce ops) and treat it just as byte arrays..
todos: macroize it as we do it 10 different ways, add mca params to control handling (push up size, no change, switch off segmenting)

6b22641669 added LibNBC (http://www.unixer.de/NBC) as collv1 (blocking) component.
I know it does not make much sense but one can play around with the
performance. Numbers are available at http://www.unixer.de/research/nbcoll/perf/.
This is the first step towards collv2. Next step includes the addition
of non-blocking functions to the MPI-Layer and the collv1 interface.

It implements all MPI-1 collective algorithms in a non-blocking manner.
However, the collv1 interface does not allow non-blocking collectives so
that all collectives are used blocking by the ompi-glue layer.

I wanted to add LibNBC as a separate subdirectory, but I could not
convince the buildsystem (and had not the time). So the component looks
pretty messy. It would be great if somebody could explain me how to move
all nbc*{c,h}, and {hb,dict}*{c,h} to a seperate subdirectory.

It's .ompi_ignored because I did not test it exhaustively yet.

6afa4c6c64 Windows friendly version. We have to split the OMPI_DECLSPEC in at least 3
different macros, one for each project. Therefore, now we have OPAL_DECLSPEC,
ORTE_DECLSPEC and OMPI_DECLSPEC. Please use them based on the sub-project.

f64cbbe8f2 ops. some decisions used extent rather than size for decision making
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

c31a5ad4b3 A few small changes that just expanded in the name of neatness...
(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

566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)

25375759c3 arrgh. reduce could for very small message sizes and proc counts call a linear function
this was implemented using a chain (tree followed with pipeline) by setting the chain fanout to a factor of size etc but the chain datastructure was fixed in length and if exceeded the topo create returned a null which isn't helpfull in cid next function of comdup...
Anyway two fixes, first we do have a real linear function so changed the decision function and second altered the
topo chain create to force chain fanouts of less than 1 to 1 and fanouts bigger than max to max.
next check in will change chain to dynamically allocd array (reallocable) but we shouldn't ever use a chain fanout for a linear tree anyway. 
(lession must rerun all tests for all data sizes when changing decision functions)

54c4bd3ce2 Update to have public symbols be consistent; use new prefix rule
(apparently we've been doing this in opal and orte, but not in ompi
yet).  All public symbols begin with "ompi_coll_tuned_" (not
mca_coll_tuned_) except the component struct.  Now this component
passes the illegal symbol report with no hits.

83cef7f8ac in scatterv we tested unfortunatly the wrong datatype for the
displacement (for both the inter and intra-communicator version). The
displacements in scatterv are given in multiples of the sendtype.
This fix should probably make to v1.0.1 as well?
