configure: add a summary section at the end of configure output This commit adds two m4 macros: OPAL_SUMMARY_ADD, OPAL_SUMMARY_PRINT. OPAL_SUMMARY_ADD adds an item to a section in the summary. For example OPAL_SUMMARY_ADD([[Transports]],[[Foo]],...,[yes]) will add the following to the summary: Transports ----------------------- Foo: yes With this commit two sections are added: Transports, Resource Managers. The OPAL_SUMMARY_PRINT macro is called after AC_OUTPUT and prints out some information about the build (version, projects, etc) and then the summarys sections. It will additionally print a warning if internal debugging is enabled. Example output: Open MPI configuration: ----------------------- Version: 3.0.0 a1 Build Open Platform Abstration project: yes Build Open Runtime project: yes Build Open MPI project: yes Build Open SHMEM project: no MPI C++ bindings (deprecated): no MPI Fortran bindings: mpif.h, use mpi, use mpi_f08 Debug build: yes Transports ----------------------- Cray uGNI (Gemini/Aries): no Intel Omnipath (PSM2): no KNEM Shared Memory: no Linux CMA IPC: no Mellanox MXM: no Open UCX: no OpenFabrics libfabric: no OpenFabrics Verbs: no portals4: no QLogic Infinipath (PSM): no tcp: yes XPMEM Shared Memory: no Resource Managers ----------------------- Cray Alps: no Grid Engine: no LSF: no Slurm: yes Torque: yes INTERNAL DEBUGGING IS ENABLED.

btl/vader: improved single-copy support This commit makes the folowing changes: - Add support for the knem single-copy mechanism. Initially vader will only support the synchronous copy mode. Asynchronous copy support may be added int the future. - Improve Linux cross memory attach (CMA) when using restrictive ptrace settings. This will allow Open MPI to use CMA without modifying the system settings to support ptrace attach (see /etc/sysctl.d/10-ptrace.conf). - Allow runtime selection of the single copy mechanism. The default behavior is to use the best available. The priority list of single-copy mehanisms is as follows: xpmem, cma, and knem. - Allow disabling support for kernel-assisted single copy. - Some tuning and bug fixes.
