When specifying multiple applications, you must specify how many processes of each to launch via the -np argument. # [orte-rmaps-lama:oversubscribe] RMaps LAMA detected oversubscription after mapping %d of %d processes. Since you have asked not to oversubscribe the resources the job will not be launched. If you would instead like to oversubscribe the resources try using the --oversubscribe option to mpirun. # [orte-rmaps-lama:no-resources-available] RMaps LAMA detected that there are not enough resources to map the remainder of the job. Check the command line options, and the number of nodes allocated to this job. Application Context : %d # of Processes Successfully Mapped: %d # of Processes Requested : %d Mapping : %s Binding : %s MPPR : %s Ordering : %s # [orte-rmaps-lama:merge-conflict-bad-prune-src] RMaps LAMA detected that it needed to prune a level of the hierarchy that was necessary for one of the command line parameters. Check your allocation and the options below to make sure they are correct. Conflicting Level Description: %s Mapping : %s Binding : %s MPPR : %s Ordering : %s # [invalid mapping option] The specified mapping option is not supported with the LAMA rmaps mapper: Specified mapping option: %s Reason it is invalid: %s LAMA supports the following options to the mpirun --map-by option: node, numa, socket, l1cache, l2cache, l3cache, core, hwthread, slot Alternatively, LAMA supports specifying a sequence of letters in the rmaps_lama_map MCA parameter; each letter indicates a "direction" for mapping. The rmaps_lama_map MCA parameter is richer/more flexible than the --may-by CLI option. If rmaps_lama_map is specified, the following letters must be specified: h: hardware thread c: processor core s: processor socket n: node (server) The following may also optionally be included in the mapping string: N: NUMA node L1: L1 cache L2: L2 cache L3: L3 cache For example, the two commands below are equivalent: mpirun --mca rmaps lama --mca rmaps_lama_map csNh ... mpirun --mca rmaps lama --map-by core ... # [invalid binding option] The specified binding option is not supported with the LAMA rmaps mapper: Specified binding option: %s Reason it is invalid: %s LAMA binding options can be specified via the mpirun --bind-to command line option or rmaps_lama_bind MCA param: --bind-to rmaps_lama_binding Locality option option ---------------- --------- ------------------ Hardware thread hwthread h Processor core core c Processor socket socket s NUMA node numa N L1 cache l1cache L1 L2 cache l2cache L2 L3 cache l3cache L3 Node (server) node n The --bind-to option assumes a single locality (e.g., bind each MPI process to a single core, socket, etc.). The rmaps_lama_bind MCA param requires an integer specifying how many localities to which to bind. For example, the following two command lines are equivalent, and bind each MPI process to a single core: mpirun --btl rmaps lama --mca rmaps_lama_bind 1c ... mpirun --btl rmaps lama --bind-to core ... The rmaps_lama_bind MCA parameter is more flexible than the --bind-to CLI option, because it allows binding to multiple resources. For example, specifing an rmaps_lama_bind value of "2c" binds each MPI process to two cores. # [invalid ordering option] The specified ordering option is not supported. Specified ordering option: %s The LAMA ordering can be specified via the rmaps_lama_ordering MCA parameter. Two options are supported for ordering ranks in MPI_COMM_WORLD (MCW): s: Sequential. MCW rank ordering is sequential by hardware thread across all nodes. E.g., MCW rank 0 is the first process on node 0; MCW rank 1 is the second process on node 0, and so on. n: Natural. MCW rank ordering follows the "natural" mapping layout. For example, in a by-socket layout, MCW rank 0 is the first process on the 1st socket on node 0. MCW rank 1 is then the first process on the 2nd socket on node 0. And so on. # [invalid mppr option] The specified Max Processes Per Resource (MPPR) value is invalid (in the rmaps_lama_mppr MCA paramter): Specified MPPR: %s Reason is is invalid: %s The MPPR is a comma-delimited list of specifications indicating how many processes are allowed on a given type of resource before an MPI job is considered to have oversubscribed that resource. Each specification is a token in the format of "NUMBER:RESOURCE". For example, the default MPPR of "1:c" means that Open MPI will map one process per processor core before considering cores to be oversubscribed. Multiple specifications may be useful; for example "1:c,2:s" maintains the default one-process-per-core limitation, but places an additional limitation of only two processes per processor socket (assuming that there are more than two cores per socket). The LAMA MPPR specifications are set via the rmaps_lama_mppr MCA parameter. The following resources can be specified: Hardware thread h Processor core c Processor socket s NUMA node N L1 cache L1 L2 cache L2 L3 cache L3 Node (server) n # [internal error] An unexpected internal error occurred in the LAMA mapper; your job will now fail.
