know that the request is inactive we don't have to call fini). Remove if's from
the critical path. Change a do in while to make sure we do the minimum in all cases.
All in all it decrease the latency for mvapi by something between 0.15 and 0.20
micro-seconds. But it's just a first step ...

increased the datatype ref count, and there is no way to have a convertor without a valid
request, so there is no need for the convertor to increase the reference count of the datatype
again. Therefore, if one want to use the datatype for something else than MPI request, one
has to manage the reference counts outside the datatype layer.

thread finish a request between the moment when we check the request status and the moment
when we acquire the lock, and if there are no more pending request on the pipe we will be
stuck foreverr as nobody have any reason to broadcast the request condition. I check the
req_any and it doesn't contain the same bug.

the descriptors to vanish. The PML was thinking that they are in the btl_cache when they
weren't ... It lead to memory consumption on most environments when compiled with
thread enabled. After modification the latency went down by nearly 0.5 microseconds.
Simple way to trigger the bug: limit the number of maximum items in the free list and run
any communication intensive application (like Netpipe).

- Move mca_btl_udapl_error/mca_btl_module_init to mca_btl_udapl.c and rename it
- White space cleanups
- Free the uDAPL evd and ia handles in mca_btl_udapl_finalize

- fall back to compile test for windows paffinity component
when cross compiling
- fall back to platform guess when checking for threads having
different pids with pthreads (yes on linux, no elsewhere)
- pass the proper host, target, and build flags to the
ROMIO configure script
With these changes, cross-compiling should be possible with the exception
of the Fortran 77 and Fortran 90 bindings. Fortran 77 can be cross-
compiled if cache values are provided for type sizes and alignment.

- Borrow configure.m4 from the mvapi btl. One of the uDAPL headers emits a
warning when -pedantic is enabled, so strip it out.
- Change function check in ompi_check_dapl.m4 from dat_ia_open to
dat_registry_list_providers.. dat_ia_open wasn't working right
- Make the references to prepare_dst, put, and get NULL for now
- Add opal_output() calls in all the udapl interface functions for debugging
- Add evd_qlen component parameter to control event dispatcher queue length
- First stab at component_init and module_init
- Misc cleanups - whitespace, dead code removal
- Update copyrights to 2006

r8698), with changes below:
- Split wrapper flags into those required for each of the three projects,
and cleaned up some cruft (including the LIBMPI_EXTRA_*FLAGS) through-
out the build system
- Added opal_init_util and opal_finalize_util to allow init / cleanup
of all the opal code that doesn't require the MCA system
- Create standalone key=value file parser, based on the one that used
to be in the mca param parser, so that it can be shared in multiple
places
- Add wrapper datafiles for opal, orte, and ompi wrappers, and add
wrapper compiler with support for all the old features

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)

As the common part is the one that create the shred memory file it seems
logical to make it destroy the file as well. Therefore, the code for
unmapping the file is in a common place.

On some systems (like windows) qsort can modify the order of modules when the
comparaison function return 0. As we expect to have the
mca_btl_sm_add_procs_same_base_addr called before mca_btl_sm_add_procs we have
force the qsort to return the SM modules in the correct order. Giving to the
same_addr module a slightly higher priority solve this problem.

"ln -s" on all Unixes and to "cp -p" on windows).
When we remove an executable use the correct extension for its name
(add $(EXEEXT) to the name).
