Hello,

I wonder what is the correct way to tell mpirun that all processes should 
be run on specific NUMA node. I know that if I want to distribute processes 
evenly between all NUMA nodes I can use `--map-by numa --bind-to numa`. I 
guess if I need to run all processes on one node I should use --map-by, 
however I haven't figured out what argument  do I need to pass. For now I 
use something like `numactl -N $NODE -m $NODE mpirun --bind-to none ...`, 
however it feels to me like an ugly hack.

Thank you for any suggestions!
