So there are two options here that will work and hopefully provide you with the desired pattern:
* if you want the procs to go in different NUMA regions: $ mpirun --map-by numa:PE=2 --report-bindings -n 2 /bin/true [rhc001:131460] MCW rank 0 bound to socket 0[core 0[hwt 0-1]], socket 0[core 1[hwt 0-1]]: [BB/BB/../../../../../../../../../..][../../../../../../../../../../../..] [rhc001:131460] MCW rank 1 bound to socket 1[core 12[hwt 0-1]], socket 1[core 13[hwt 0-1]]: [../../../../../../../../../../../..][BB/BB/../../../../../../../../../..] * if you want the procs to go in the same NUMA region: $ mpirun --map-by ppr:2:numa:PE=2 --report-bindings -n 2 /bin/true [rhc001:131559] MCW rank 0 bound to socket 0[core 0[hwt 0-1]], socket 0[core 1[hwt 0-1]]: [BB/BB/../../../../../../../../../..][../../../../../../../../../../../..] [rhc001:131559] MCW rank 1 bound to socket 0[core 2[hwt 0-1]], socket 0[core 3[hwt 0-1]]: [../../BB/BB/../../../../../../../..][../../../../../../../../../../../..] Reason: the level you are mapping by (e.g., NUMA) must have enough cores in it to meet your PE=N directive. If you map by core, then there is only one core in that object.
