Ralph Castain 40a2bfa238 WARNING: Work on the temp branch being merged here encountered problems with bugs in subversion. Considerable effort has gone into validating the branch. However, not all conditions can be checked, so users are cautioned that it may be advisable to not update from the trunk for a few days to allow MTT to identify platform-specific issues. This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change. Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation. This commit was SVN r23764.		2010-09-17 23:04:06 +00:00

This extension provides a single new function, OMPI_Affinity_str(),
that provides 3 prettyprint strings as output:

ompi_bound: describes what sockets/cores Open MPI bound this process
to (or indicates that Open MPI did not bind this process).

currently_bound: describes what sockets/cores this process is
currently bound to (or indicates that it is unbound).

exists: describes what processors are available in the current host.

See OMPI_Affinity_str(3) for more details.
