Added a new System V (sysv) shared memory component for Open MPI. Configure Option: --enable-sysv MCA Parameter: mpi_common_sm mpi_common_sm accepts a comma delimited list of: [sysv],mmap (order dependent). The first component that is successfully selected is used. For example, -mca mpi_common_sm sysv,mmap will first try sysv. If sysv is not successfully selected, then mmap will be used. mmap will be used if mpi_common_sm is not provided. Notes: Please make certain that your system's shmmax limit, or equivalent, is larger than mpool_sm_min_size. Otherwise, shmget may fail. This commit was SVN r23260.

New POSIX shared memory component and other common sm enhancements. NOTE: mmap is still the default. Some highlights: o Silent component failover. o The sysv component will only be queried for selection if it is placed before the mmap component (for example, -mca mpi_common_sm sysv,posix,mmap). In the default case, sysv will never be queried/selected. o Per some on-list discussion, now unlinking mmaped file in both mmap and posix components (see: "System V Shared Memory for Open MPI: Request for Community Input and Testing" thread). o Assuming local process homogeneity with respect to all utilized shared memory facilities. That is, if one local process deems a particular shared memory facility acceptable, then ALL local processes should be able to utilize that facility. As it stands, this is an important point because one process dictates to all other local processes which common sm component will be selected based on its own, local run-time test. o Addressed some of George's code reuse concerns. This commit was SVN r23633.

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.
