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.
