and implementation. This has shown drastic performance benefit when
transferring Many files at roughly the same time.
I tested this for many different filem operations and everything was working
fine. Let me know if you have any problems with this functionality.
Some Notes:
- opal-checkpoint now has a 'quiet' flag to keep it from being too verbose.
- FileM RSH component is fully non-blocking.
- FileM RSH component has incomming connection throttling since by default
ssh only allows 10 concurrent scp connections to any single host. This
default can be adjusted via an MCA parameter.
{{{-mca filem_rsh_max_incomming 10}}}
- There is an MCA parameter for max outgoing connections, but it is currently
not implemented. If someone needs it then it should not be hard to implement.
{{{-mca filem_rsh_max_outgoing 10}}}
- Changed the FileM request structure so that it is a bit more explicit and
flexible.
- Moved the 'preload-binary' and 'preload-files' functionality into odls/base
allowing for code reuse in the 'process' and 'default' ODLS components.
- Fixed a bug in the process name resolution which broke the 'preload-*'
functionality due to GPR table structure changes.
- The FileM RSH component might be able to see even more speedup from using a
thread pool to operate on the work_pool structures, but that is for future
work.
- Added a 'opal-show-help' file to ODLS Base

from each of the communicators, that MPI_COMM_NULL doesn't have a group.
Also fix the code from skipping over every other communicator when
freeing the groups.

Minor change to ompi_mca.m4 to move AC_CONFIG_FILES(framework/makefile) in autogen process (instead of configure process), where we still now the actual framework path (instead of guessing using $project/mca/$framework).
This have shown no side effects in our testing. Let us know if this breaks one of your components in some exotic context.

numbers for tuning.
Switch the bookmark_recv to be non-blocking. If this is blocking then for
process counts >= 32 slight process delays were causing cascading performance
delays in the protocol. This lead to checkpoints either taking about 3 sec or
45 sec (or more) for 64 procs due to the cascading delays. With the nonblocking
receive version this is no longer the case we get the speedup we expect for this
part of the protocol.
More tuning to come.

There is a reason that we use the internal type (ompi_file_errhandler_fn) instead of the MPI typedef. When building without MPI-IO support (--disable-mpi-io), the MPI type is not defined, but the internal type IS defined in order to try to keep binary compatibility for apps that don't use MPI-IO.
