Refs trac:2698 After a long period of development with many starts and stops, we finally got this where we wanted it. This commit introduces 2 new MCA params (note that the "maffinity_libnuma_policy" MCA param introduced by r24290 was removed when libnuma support was removed). Remember that maffinity policies are only in effect when paffinity is enaabled -- i.e., when processes are bound to processors! * '''maffinity_base_alloc_policy:''' Policy that determines how general memory allocations are bound after MPI_INIT. A value of "none" means that no memory policy is applied. A value of "local_only" means that all memory allocations will be restricted to the local NUMA node where each process is placed. Note that operating system paging policies are unaffected by this setting. For example, if "local_only" is used and local NUMA node memory is exhausted, a new memory allocation may cause paging. * '''maffinity_base_bind_failure_action:''' What Open MPI will do if it explicitly tries to bind memory to a specific NUMA location, and fails. Note that this is a different case than the general allocation policy described by maffinity_base_alloc_policy. A value of "warn" means that Open MPI will warn the first time this happens, but allow the job to continue (possibly with degraded performance). A value of "error" means that Open MPI will abort the job if this happens. This needs at least a little soak time on the trunk before going to v1.5. This commit was SVN r24639.

Move maffinity_base_alloc_policy and maffinity_base_bind_failure_action MCA params to the hwloc base (hwloc_base_alloc_polocy and hwloc_base_bind_failure_action). Since these MCA parameters were never on a release branch, I'm just moving/renaming them outright and not leaving aliases to the old names. Note that some upper layer needs to call opal_hwloc_base_set_process_membind_policy() to set the set-by-MCA-param process-wide memory affinity policy. We can't do this automatically during hwloc_base_open() because, for reasons described elsewhere, opal_hwloc_topology is not automatically filled during hwloc_base_open() (in short: potential scalability issues when launching many MPI processes simultaneously on a single machine, for example). This commit was SVN r25156.
