      Simplified RMA_Op structure. · 274a5a70
      Pavan Balaji authored
      We were creating duplicating information in the operation structure
      and in the packet structure when the message is actually issued.
      Since most of the information is the same anyway, this patch just
      embeds a packet structure into the operation structure.

      Make handling of request cleanup more uniform · 1e171ff6
      Wesley Bland authored
      There are quite a few places where the request cleanup is done via:
      MPIU_Object_set_ref(req, 0);
      when it should be:
      This makes the handling more uniform so requests are cleaned up by releasing
      references rather than hitting them with the destroy hammer.
      Fixes #1664

      Removed unused single_op_opt field from MPID_Request · 255fb4a6
      James Dinan authored
      The single_op_opt flag in the request object was previously used to
      track whether an operation is a lock-op-unlock type, for the purposes of
      completion.  Tracking this state has been merged into the packet header
      flags, so the single_op_opt flag is no longer needed.

      RMA sync. piggybacking from origin->target · 4e67607f
      James Dinan authored
      This patch uses packet header flags to piggyback the unlock operation on other
      RMA operations.  For most operations, there is no net change.  However, FOP and
      GACC, unlock piggybacking was previously not implemented.

      Consolidated RMA op finalization code · bba35589
      James Dinan authored
      This patch consolidates the synchronization and tracking of RMA operations into
      a single routine that is called whenever we complete an operation.  The only
      exception are lock-op-unlock operations that are completed from within the lock
      operation processing code.
      This code is pretty ugly, but it will get cleaner once packet flags are been

      Partially reverted [0b364068] in preparation for incorporating new
      piggybacking infrastructure.  This temporarily re-introduces that bug
      and it will be fixed again with the new piggybacking patch.

      BUGFIX: Unlock piggybacking for Get_accumulate · 0b364068
      James Dinan authored
      GACC operations were both piggybacking the unlock message to the origin, and
      sending back a PT done packet.  This was causing the origin to be unlocked
      twice.  When another lock operation was performed between the GACC and PT done
      unlock operations, there was a synchronization race.

      [svn-r10249] Updated fetch_and_op implementation · 9574b9ab
      James Dinan authored
      Updated the fetch_and_op implementation to have two data transfer paths; one
      where data can be embedded in the packet header and one where it is sent
      separately.  With this change, the header size is back to 40 bytes.

      [svn-r7416] Major improvement to RMA performance for long lists of operations, an immediate mode accumulate for single ints, store the MPID_Comm within the window, and added a basic performance instrumentation interface that was extensively used to improve the RMA performance (enabled with --enable-g=instr).  With these fixes, MPICH2 can run the one-sided version of the Graph500 benchmark at a respectable if not great rate

      [svn-r4062] 1) Modifying the datatype code to find the number of contig blocks in an instance of an MPI derived datatype - Since finding the real number of contig blocks is not easy we find a reasonable upper bound instead. This also fixes the case where the number of contig blocks was uninitialized for contiguous datatypes.

      William Gropp authored
      [svn-r3070] Added ATTRIBUTE((unused)) (which is defined to work with gcc and disappear for other compilers only to the functions whose arguments are defined by a general pattern (such as a request handler) and thus must be used even if not needed.  For functions that have parameters that are not used and are not needed to conform to a pattern, do not use ATTRIBUTE((unused)), instead, fix the routine to either make use of the argument in a real way or change the routine to not pass the argument.
