   @qw42 , you can use master branch or release version >= 1.2.0.
   
   A simple experiment by following commands. 
   
   ```
   export OMP_NUM_THREADS=${CORES_NUM}
   mem_num=0
   COMMAND="numactl -C 0-$[${CORES_NUM}-1] -m ${mem_num} python XXX.py"
   for ((i=1;i<${INSTANCES};i++))
           do
                 if [ $[${CORES_NUM}*$i] -ge 28 ];then
                  mem_num=1
                  fi
                 COMMAND+=" & numactl -C 
$[${CORES_NUM}*$i]-$[${CORES_NUM}*$i+${CORES_NUM}-1] -m ${mem_num} python 
XXX.py"
           done
   echo ${COMMAND} > run_instance.sh
   bash -x run_instance.sh
   ```
