- Added some basic flow control to limit number of posted sends.
- Merged endpoint send/recv lock into single endpoint lock.
- Set the LMR triplet length in the send path, not at allocation time.
This has to be done because upper layers might send less than the
amount allocated.
- Alter the tie-breaker if statement protecting the second call
to dat_ep_connect(). The logic was reversed compared to the tie-
breaker for the first dat_ep_connect(), making it possible for
3 or more processes to form a deadlock loop.
- Some asserts were added for debugging purposes.. leaving them
in place for now.

Not much got tested that wasn't already - I've uncovered a connection
establishment deadlock and wanted to get these changes committed before I
attack it.
The big changes:
- Moved much of the connection code from btl_udapl_component.c to
btl_udapl_endpoint.c.
- Cleaned up initialization of various fragment members.
- MCA_BTL_UDAPL_ERROR macro, which is compiled in/out appropriately.
This commit was SVN r9496.
In short, I'm very close to having connection establishment and eager send/recv working.
Part of the connection process involves sending address information from the
client to server. For some reason, I am never receiving an event indicating
completetion of the send on the client side. Otherwise, connection
establishment is working and eager send/recv should be trivial from here.
Some more detailed changes:
- Send partially implemented, just handles starting up new connections.
- Several support functions implemented for establishing connection. Client
side code went in btl_udapl_endpoint.c, server side in btl_udapl_component.c
- Frags list and send/recv locks added to the endpoint structure.
- BTL sets up a public service point, which listens for new connections.
Steps over ports that are already bound, iterating through a range of ports.
- Remove any traces of recv frags, don't think I need them after all.
- Pieces of component_progress() implemented for connection establishment.
- Frags have two new types for connection establishment - CONN_SEND and
CONN_RECV.
- Many other minor cleanups not affecting functionality
This commit was SVN r9345.
- 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)
This commit was SVN r8985.
- Start filling in the progress function, focusing on connection establishment.
- Initialize udapl mpool and free lists
- Create/destroy a protection zone with each IA
- Misc organization as I learn how things work
This commit was SVN r8969.
- 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
This commit was SVN r8705.
- 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
This commit was SVN r8701.
- Copied the template BTL and renamed everything
- Compiles and shows up correctly in ompi_info, not tested past that
- Should be ignored for everyone but me
This commit was SVN r8544.
