1. taskset
taskset 명령어는 running 중인 process의 CPU affinity를 확인하거나 설정하는 도구
특정 process의 affinity mask를 확인하는 방법
| [root@localhost etc]# ps -ef | grep mysqld mysql 2237 1 0 05:48 ? 00:00:01 /usr/sbin/mysqld root 2333 2022 0 06:02 pts/0 00:00:00 grep --color=auto mysqld [root@localhost etc]# taskset -p 2237 pid 2237's current affinity mask: ffffffff |
affinity mask는 2진수 값으로 설정하며 이를 16진수로 표현
| 8개의 논리 CPU에 대한 마스크는 8자리 00000000 첫 번째와 두 번째 CPU 00000011 => 0x03 첫 번째와 마지막 CPU 10000001 => 0x81 모든 홀수 번째 CPU 01010101 => 0x55 모든 CPU 11111111 => 0xff |

NUMA 정책
| Policy settings are: --all, -a Unset default cpuset awareness, so user can use all possible CPUs/nodes for following policy settings. --interleave=nodes, -i nodes Set a memory interleave policy. Memory will be allocated using round robin on nodes. When memory can‐ not be allocated on the current interleave target fall back to other nodes. Multiple nodes may be specified on --interleave, --membind and --cpunodebind. --membind=nodes, -m nodes Only allocate memory from nodes. Allocation will fail when there is not enough memory available on these nodes. nodes may be specified as noted above. --cpunodebind=nodes, -N nodes Only execute command on the CPUs of nodes. Note that nodes may consist of multiple CPUs. nodes may be specified as noted above. --physcpubind=cpus, -C cpus Only execute process on cpus. This accepts cpu numbers as shown in the processor fields of /proc/cpuinfo, or relative cpus as in relative to the current cpuset. You may specify "all", which means all cpus in the current cpuset. Physical cpus may be specified as N,N,N or N-N or N,N-N or N- N,N-N and so forth. Relative cpus may be specifed as +N,N,N or +N-N or +N,N-N and so forth. The + indicates that the cpu numbers are relative to the process' set of allowed cpus in its current cpuset. A !N-N notation indicates the inverse of N-N, in other words all cpus except N-N. If used with + notation, specify !+N-N. --localalloc, -l Always allocate on the current node. --preferred=node Preferably allocate memory on node, but if memory cannot be allocated there fall back to other nodes. This option takes only a single node number. Relative notation may be used. --show, -s Show NUMA policy settings of the current process. --hardware, -H Show inventory of available nodes on the system. |
--membind 옵션을 사용하여 프로세스를 구동하면, 지정한 NUMA Node의 메모리가 부족한 경우 프로세스 종료
--preferred 옵션을 사용하여 프로세스를 구동하면, 선호 NUMA Node의 메모리가 부족한 경우 다른 NUMA Node의 메모리 사용
--cpunobind 옵션을 사용하여 프로세스를 구동하면, 가급적 프로세스가 동작하고 있는 CPU의 Local Memory에 접근 시도, 특정 프로세스가 전체 Core를 사용하지 않는 방식이라면 이러한 방법이 좋은 전략이 될 수 있음
--interleave=all 옵션을 사용하여 프로세스를 구동하면, 모든 NUMA Node에 Memory가 골고루 할당, 하나의 NUMA Node가 보유한 Memory 크기 이상을 필요로 하는 Application에 유리한 정책일 수 있음
만약, mysql 프로세스에 정책을 부여하려면 다음과 같이 numactl 사용 가능
# numactl --interleave=all mysqld &
다음과 같은 에러 발생 시, /etc/my.cnf 파일에 user=mysql 라인 추가
| [root@localhost ~]# numactl --interleave=all mysqld 2023-06-09T08:50:15.273310Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.33) starting as process 6532 2023-06-09T08:50:15.275593Z 0 [ERROR] [MY-010123] [Server] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root! 2023-06-09T08:50:15.275639Z 0 [ERROR] [MY-010119] [Server] Aborting 2023-06-09T08:50:15.276252Z 0 [System] [MY-010910] [Server] /usr/sbin/mysqld: Shutdown complete (mysqld 8.0.33) MySQL Community Server - GPL. |

3. numastat
현재 NUMA 운영 상태 확인 도구
numa_miss, numa_foreign이 높다는 것은 의도한대로 메모리가 할당되지 못하고 있다는 것을 의미하기 때문에 이를 줄이는 것이 보다 효율성을 높이는 방법
## local_node : 프로세스가 local node에서 실행되고, 메모리도 local node에서 할당한 케이스
## other_node : 프로세스가 other node에서 실행되고, 메모리는 local node에서 할당한 케이스
## NUMA Node0의 local_node와 NUMA Node1의 other_node는 NUMA Node0에서 실행 중인 프로세스가 사용 중인 메모리
## NUMA Node1의 local_node와 NUMA Node0의 other_node는 NUMA Node1에서 실행 중인 프로세스가 사용 중인 메모리

Each numa_miss has a numa_foreign on another node. * numa_foreign is memory intended for this node, but actually allocated on some different node.
