Clean up the remainder of the size_t references in the runtime itself. Convert to orte_std_cntr_t wherever it makes sense (only avoid those places where the actual memory size is referenced).
Remove the obsolete oob barrier function (we actually obsoleted it a long time ago - just never bothered to clean it up).
I have done my best to go through all the components and catch everything, even if I couldn't test compile them since I wasn't on that type of system. Still, I cannot guarantee that problems won't show up when you test this on specific systems. Usually, these will just show as "warning: comparison between signed and unsigned" notes which are easily fixed (just change a size_t to orte_std_cntr_t).
In some places, people didn't use size_t, but instead used some other variant (e.g., I found several places with uint32_t). I tried to catch all of them, but...
Once we get all the instances caught and fixed, this should once and for all resolve many of the heterogeneity problems.

allocation. This is necessary to detect if the user requests a specific
mpool for the allocationi. Searching the key values for a specific mpool
name does not work for the case that the user provides an info object
without mpool specific information (see Ticket #254).
- In the case that the user provides a info object without requesting a
specific mpool we use malloc to allocate buffer instead of returning
NULL (fix for Ticket #254 )

addition to my design and testing, it was conceptually approved by
Gil, Gleb, Pasha, Brad, and Galen. Functionally [probably somewhat
lightly] tested by Galen. We may still have to shake out some bugs
during the next few months, but it seems to be working for all the
cases that I can throw at it.
Here's a summary of the changes from that branch:
* Move MCA parameter registration to a new file (btl_openib_mca.c):
* Properly check the retun status of registering MCA params
* Check for valid values of MCA parameters
* Make help strings better
* Otherwise, the only default value of an MCA param that was
changed was max_btls; it went from 4 to -1 (meaning: use all
available)
* Properly prototyped internal functions in _component.c
* Made a bunch of functions static that didn't need to be public
* Renamed to remove "mca_" prefix from static functions
* Call new MCA param registration function
* Call new INI file read/lookup/finalize functions
* Updated a bunch of macros to be "BTL_" instead of "ORTE_"
* Be a little more consistent with return values
* Handle -1 for the max_btls MCA param
* Fixed a free() that should have been an OBJ_RELEASE()
* Some re-indenting
* Added INI-file parsing
* New flex file: btl_openib_ini.l
* New default HCA params .ini file (probably to be expanded over
time by other HCA vendors)
* Added more show_help messages for parsing problems
* Read in INI files and cache the values for later lookup
* When component opens an HCA, lookup to see if any corresponding
values were found in the INI files (ID'ed by the HCA vendor_id
and vendor_part_id)
* Added btl_openib_verbose MCA param that shows what the INI-file
stuff does (e.g., shows which MTU your HCA ends up using)
* Added btl_openib_hca_param_files as a colon-delimited list of INI
files to check for values during startup (in order,
left-to-right, just like the MCA base directory param).
* MTU is currently the only value supported in this framework.
* It is not a fatal error if we don't find params for the HCA in
the INI file(s). Instead, just print a warning. New MCA param
btl_openib_warn_no_hca_params_found can be used to disable
printing the warning.
* Add MTU to peer negotiation when making a connection
* Exchange maximum MTU; select the lesser of the two

implemented entirely on top of the PML. This allows us to have a
one-sided interface even when we are using the CM PML and MTLs for
point-to-point transport (and therefore not using the BML/BTLs)
* Old pt2pt component was renamed "rdma", as it will soon be having
real RDMA support added to it.

than $(LN_S). This causes problems with with Windows and probably
elsewhere (re: #200). So use a slightly different trick to get the
right header selected for the MEMCPY and TIMER components.
* Using the same trick used to solve the AC_CONFIG_LINKS problem,
stop using a separate header file for direct calling in the
PML and MTL. This lets me remove some icky code in ompi_mca.m4
that was more fragile than I really liked.

We now set truncation error if we received more than we delivered for both
the OB1 and DR PMLs (the CM PML doesn't need such a fix, as the condition
is set at the MTL level)

reuse the pml_base_request_t as it was just too heavy for our needs. Lots of
code for 2/10 usec ;-)

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.

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).

mpi_leave_pinned when multiple OpenIB HCA ports are found.
Specifically, if mpi_leave_pinned == 1 and ultiple HCA ports are
found, the MCA parameter btl_openib_max_btls is set to 1. If the MCA
parameter btl_openib_warn_leave_pinned_multi_port is true, emit a
warning that this happened (having an MCA parameter to control the
warning allows users/sysadmins to turn it off instead of being nagged
for every run).
