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.
