I want to know whether the NUMA bound memory node with CONFIG_CGROUPS related or associted with NUMA binding. I wrote an example test,the results are as follows. > euler-linux:/home/zhongjiang # numactl --membind=1 ./new & > [1] 6529 > euler-linux:/home/zhongjiang # ps -ef | grep new > root 6529 4483 0 14:40 pts/1 00:00:00 ./new > root 6556 4483 0 14:40 pts/1 00:00:00 grep new > euler-linux:/home/zhongjiang # cat /proc/6529/status > Name: new > State: S (sleeping) ........ > Cpus_allowed: ffffff > Cpus_allowed_list: 0-23 > Mems_allowed: 00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,007fffff > Mems_allowed_list: 0-22 > voluntary_ctxt_switches: 19 > nonvoluntary_ctxt_switches: 0 euler-linux:/home/zhongjiang # numactl --membind=3 ./new & [1] 9113 euler-linux:/home/zhongjiang # ps -ef | grep mew root 9140 8948 0 14:55 pts/1 00:00:00 grep mew euler-linux:/home/zhongjiang # ps -ef | grep new root 9113 8948 0 14:55 pts/1 00:00:00 ./new root 9209 8948 0 14:55 pts/1 00:00:00 grep new euler-linux:/home/zhongjiang # cat /proc/9113/status Name: new State: S (sleeping) Tgid: 9113 Ngid: 0 Pid: 9113 PPid: 8948 ......
