Is it correct? As far as I browse the source code, map-by slot is used if
np <=2.
[mishima@manage openmpi-1.7.4rc2r30425]$ cat -n
orte/mca/rmaps/base/rmaps_base_map_job.c
...
107 /* default based on number of procs */
108 if (nprocs <= 2) {
109 opal_output_verbose(5,
orte_rmaps_base_framework.framework_output,
110 "mca:rmaps mapping not given -
using byslot");
111 ORTE_SET_MAPPING_POLICY(map->mapping,
ORTE_MAPPING_BYSLOT);
112 } else {
113 opal_output_verbose(5,
orte_rmaps_base_framework.framework_output,
114 "mca:rmaps mapping not given -
using bysocket");
115 ORTE_SET_MAPPING_POLICY(map->mapping,
ORTE_MAPPING_BYSOCKET);
116 }
