the memory descriptor is closing itself, so that it actually works properly ;). I think I
was just getting lucky and not sending enough short messages with the reference impl.

* It appears that Cray's SeaStar has some horrible performance for iovecs - IN_pLACE
was actually slower than copying into eager frags. Ugh. And we don't even pre-pin
eager frags yet!

but causes resource exhaustion on the Red Storm implementation. Sigh...
This commit was SVN r9686.
The following SVN revision numbers were found above:
r9005 --> open-mpi/ompi@20d06e889e
- Some initial work on prepare_src
- Move some fragment initialization around
- Fix a union casting issue on picky compilers, identified by Don Kerr
- Other small cleanups/bugfixes
This commit was SVN r9662.
we send our local addr_t OOB. Remote side then matches endpoints and calls
dat_ep_connect(). Everything should be the same as before from here, except
that client/server roles are reversed.
- Properly set our buffer size when posting receives. When the frag used to
transfer address information is recycled by the free list, the wrong buffer
size was being used, which caused buffer overflow errors.
- Finally put the uDAPL error handling stuff in the mpool component.
- Remove a few more OPAL_OUTPUTs.
This commit was SVN r9569.
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.
- Grab the mpool_registration in _frag_common_constructor()
- Save the LMR context in the segment key
- No need for cookie variables - can just cast the frag
- No need to memcpy() data when recv'ing
- Add an LMR triplet to the fragment structure and initialize it
in btl_udapl_alloc().
- Whitespace/typo fixes, remove some opal_output() calls
Looks like I can use triplets describing sub-regions of registered LMR's. So I
do this - prior to this patch I was sending the entire free list memory over,
which isn't correct :)
Back to an earlier problem - when sending address information right after
connection establishment, the receiving end receives a DTO completion event and
appears to have good data. But the sending end never receives a DTO completion
event indicating the send completed, and never completes the client side of the
connection.
This commit was SVN r9386.
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

flag, new flags to be included when convertor is initialized
- modified pml/btl module defs and added stub functions for diagnostic
output routines to dump state of queues / endpoints
- updates to data reliability pml
This commit was SVN r9329.
- initial support for gm progress thread
- corrected threading issue in pml
- added polling progress for a configurable number of cycles to wait for threaded case

- moved hton64 and ntoh64 from the bunch of places it had been copied
into one header file
- properly set and use the btl_tcp's nbo option to put things in
network byte order on the wire if both sides don't have the same
endianness
- Put the OB1 PML's headers (with a couple exceptions I need to discuss
with Tim) in network byte order on the wire if both sides don't have
the same endianness
- since it was needed for the TCP BTL, move the orte_process_name_t
HTON and NTOH macros from the TCP OOB to ns_types.h

when running an MPI job spanning a node that has two TCP NICs and a
node that has one TCP NIC. Previously, for the 2 NIC/module process,
we would return the first peer IP address if we couldn't find a subnet
match with any of the peer's published IP addresses -- this was to
support running OMPI across subnet boundaries. Changed the behavior
to only do that behavior if the IP address we're trying to match is
public (i.e., not 10.x.y.z, 192.168.x.y, or 172.16.x.y) *and* any of
the remote peer's addresses are public (working on the assumption that
if we both have public addresses, they're routable to each other).
This definitely will not work in all scenarios, such as when we go to
WAN kinds of executions, and will need to be revisited at that time.

run-time support, as it appears to be doing bad things to memory. Update
the hack to get the local nid to match the recent TCP nal changes, and
update the P3RT api useage

- 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)

- 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

complete, but stable enough that it will have no impact on general development,
so into the trunk it goes. Changes in this commit include:
- Remove the --with option for disabling MPI-2 onesided support. It
complicated code, and has no real reason for existing
- add a framework osc (OneSided Communication) for encapsulating
all the MPI-2 onesided functionality
- Modify the MPI interface functions for the MPI-2 onesided chapter
to properly call the underlying framework and do the required
error checking
- Created an osc component pt2pt, which is layered over the BML/BTL
for communication (although it also uses the PML for long message
transfers). Currently, all support functions, all communication
functions (Put, Get, Accumulate), and the Fence synchronization
function are implemented. The PWSC active synchronization
functions and Lock/Unlock passive synchronization functions are
still not implemented

It's still not very clean as we still lock the mvapi_btl mutex inside a critical section
protected by the endpoint mutex ...
This commit was SVN r8810.
- Remove printing of CFLAGS in configure.m4
- Set MCA_BTL_FLAGS_SEND flag
- Improved error handling during module initialization
- Extract the address of each interface with dat_ia_query
- Start playing around with fragment stuff - probably wrong
- Misc code cleanup (removal of GM-specific code)
This commit was SVN r8801.
- 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

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.

- Compiles and shows up correctly in ompi_info, not tested past that
- Should be ignored for everyone but me

little bit around and removing 2 call to lock/unlock the latency for TCP

number of recv system call by caching the data. Each endpoint has a buffer
(the size is an MCA parameter) that can be use as a cache. Before each receive
operation this buffer is added at the end of the iovec list. All data that are
not expected by the fragment will go in this cache. If the cache contain data
all subsequent receive will just memcpy the data into the BTL buffers.
The only drawback is that we will spin around the receive_handle until all the
cached data is readed by the PML layer. This limitation come from the fact that
the event library is unable to call us if there is no events on the socket.
Therefore we are unable to keep the data in the cache until the next loop
into the progress engine.
