algorithm to pairwise exchange instead of the default one. This might
improve the scheduling and relax the pressure on the network.

Roll in the ORTE state machine. Remove last traces of opal_sos. Remove UTK epoch code.
Please see the various emails about the state machine change for details. I'll send something out later with more info on the new arch.

event on the ME. The events we're likely to see are LINK (the ME was
added to the match list), PUT (weird to see first, but means that the ME
was linked to the match list and then matched), or PUT_OVERFLOW, meaning
the message was unexpected.

together, so implement all functions in the MTL interface for all
MTLs. The only places NULL was still being set was for add_comm/del_comm,
and matched probe, both of which are straight forward to implement (or
return ERROR_NOT_IMPLEMENTED, since the PML can't emulate matched probe).

the ompi_message_t structure to properly initialize convertor (the peer
is available in the request in OB1, and wasn't needed when I did the
original implementation).
* Implement matched probe for the Portals4 MTL and add NULL function pointers
for the other MTLs.
* Add add_comm and del_comm functions to portals4 MTL so that direct call
almost works again.
* Add NEWS item that we've implemented matched probe

Note that the previous patch allowed the following test to -pass-:
ompi-tests/mpich_tester/mpich_pt2pt/truncmult.c
This patch makes that test -fail- due to the assumption that MPI_Wait will update the status.MPI_ERROR field. In Open MPI we do not do this, so the MPI_ERROR field being inspected will remain set to MPI_ERR_PENDING. See comments in req_wait.c for why we do this.
If we change the test to not inspect the MPI_ERROR field after calling MPI_Wait successfully, then the test would pass correctly with this patch.
This change was made per discussion on the below email thread:

* split eq into send and receive eqs so that we can control the number
of outstanding events in send eq and ensure we never lose an ack
* Shouldn't ever truncate on short unexpected receive bocks, so don't set
the truncate bit
* Track active vs. waiting for free short unexpected receive blocks so
to ensure an active short unexpected receive block is posted coming out
of flow control. Also allow creation of "temporary" blocks which should
be released once FREE event is received.
* Slight reorganization of some code in preparation for more flow control
work.

- configure:
- changed default CUPTI library path to $CUPTI-DIR/lib64
- VT Libs:
- corrected prototype of MPI_Get_address in Fortran MPI wrappers (the second parameter should be an MPI_Aint* instead of MPI_Fint*)
- temporary removed MPI_<Comm|Type|Win>_<get|set>_attr and MPI_Attr_<get|put> from the Fortran MPI wrappers due to missing conversion of the attribute value parameter
- Docu:
- latex doc \usepackage[T1]{fontenc} so that _ can be searched and copied
- smaller font in Environment Variables section
- some improvements in CUDA section
- removed GPU idle time as official feature for CUPTI tracing method
This commit was SVN r26161.
- general:
- added missing entry in ChangeLog
- vtunify[-mpi]:
- fixed possibly uninitialized global token for the predefined Node and "All" process groups
This commit was SVN r26147.
- general:
- corrected OTF version number
- otfprofile:
- removed leading '=' from CSV lines to make it loadable into spreadsheets (e.g. Open Office)
- fixed process naming in CSV output of collective operation statistics
Changes to VT:
- configure:
- added *_FOR_BUILD variables to CrayXE's default configure options; required for cross-building
- VT libs:
- fixed GPU communication, due to new process ID splitting
- fixed parsing of PAPI native events in VT_METRICS; use strtok_r instead of strtok which is successively called inPAPI_event_name_to_code
- added VT_METRICS_SEP to definition comments (-> Vampir's trace info)
- Docu:
- fixed link to TAU Reference Guide

This feature can be enabled at compile time with --with-cma passed
to configure.
At runtime it is also necessary to add "--mca btl btl_sm_use_cma 1"
to the mpirun command.
If both CMA and KNEM are compiled in and enabled at runtime then
KNEM will take precedence and CMA will disable itself
